What about dry cleaners in the off-season? How do dry cleaners spend the off-season?
The profit of dry cleaners is still considerable. Due to the fast-paced living habits, more and more people send their clothes to dry cleaners to save time.

However, if you open different dry cleaners, the profit of each dry cleaner is different. Everyone wants their dry cleaners to be the most profitable, prestigious and endless source of business. Share with you the mental journey of opening a dry cleaner.

As we all know, now is the era of science and technology, so if you want to open a profitable dry cleaner, you must first join a powerful dry cleaner, and the key is to conform to the trend of today's science and technology era.

Oberson is the first choice for dry cleaners. Oberson Smart Dry Cleaning combines traditional dry cleaning with technology to achieve unified online and offline operations. Technology-based dry cleaners radiate five kilometers online, with a wide business circle and various platforms. It also facilitates the communication between customers, allowing those old customers to drive new customers and realize secondary profits.

The equipment investment is about 30,000 yuan, and the cost is not high. If you want to open a dry cleaning, the profit is considerable, but it will take some effort to decorate the offline store, because this is the only most intuitive storefront information to convey to customers.

Oberson Smart Dry Cleaning is the most decorated in this store, and offline technology stores can also identify it, attracting customers' attention, and people can't help but enter the store to watch and retain customers.

Compared with the traditional business model, this intelligent dry cleaning attracts more people and achieves higher profits, because the income of an Oberson technology dry cleaner can be compared with that of many traditional dry cleaners.

Although the customers of traditional dry cleaners are stable, the market is relatively single, so the income is less than that of technology dry cleaners. Secondly, we should choose a suitable business model, adopt a multi-channel business model, have intelligent robots to welcome customers, and ensure that you can manage dry cleaners 24 hours a day, so that you can easily collect high profits.

The six-core technology of process solution has the most powerful performance. For users who are ready to build a high-end platform, LGA 1366 still occupies the high-end market, and Core i7-980X and Core i7-950 are still good choices.

Core i5 is a quad-core processor based on Nehalem architecture, which adopts integrated memory controller and three-level cache mode, L3 reaches 8MB, and supports the new processor computer configuration of Turbo Boost and other technologies. The main difference between it and Core i7(Bloomfield) is that the bus does not use QPI, but uses mature DMI (Direct Media Interface), and only supports dual-channel DDR3 memory. LGA 1 156 interface is adopted in the structure, and i5 has turbo technology, which can overclock under certain conditions. The processors with LGA 1 156 interface cover different users from entry-level to high-end, and the 32nm process brings lower power consumption and better performance. The mainstream representative is Core i5-650/760, and the middle and high-end representative is Core i7-870/870K. We can clearly see Intel's positioning distinction in product naming. But overall, the high-end LGA 1 156 processor is more worth buying than the low-end entry. Faced with AMD's low-cost strategy, Intel Core i3 series processors can't match it in cost performance. The performance of LGA 1 156 high-end products is more eye-catching.

Core i3 can be regarded as a further simplified version (or castrated version) of Core i5, and there will be a 32nm process version (development code-named Clarkdale, based on Westmere architecture). The biggest feature of Core i3 is the integration of GPU (graphics processor), which means that Core i3 will be encapsulated by two cores: CPU and GPU. Due to the limited performance of integrated GPU, users can add graphics cards if they want to get better 3D performance. It is worth noting that even in Clarkdale, the manufacturing process of the display core will still be 45 nanometers. The biggest difference between i3 i5 is that i3 has no turbo technology. Represented by Core i3-530/540.

20 10 in June, Intel once again released the revolutionary processor-the second generation Core i3/i5/i7. The second-generation Core i3/i5/i7 belongs to the second-generation intelligent Core family, all of which are based on the brand-new Sandy Bridge micro-architecture. Compared with the first generation products, it mainly brings five important innovations: 1, and adopts a brand-new 32nm Sandy Bridge micro-architecture, with lower power consumption and stronger performance. 2, built-in high-performance GPU (core graphics card), video coding, graphics performance is stronger. 3, Turbo Boost Technology 2.0, smarter and more efficient. 4. A new ring architecture is introduced, which brings higher bandwidth and lower delay. 5. Brand-new AVX and AES instruction sets strengthen floating-point operation and encryption and decryption operation.

SNB(Sandy Bridge) is a new generation of processor microarchitecture released by Intel at the beginning of 20 1 1. The greatest significance of this architecture lies in redefining the concept of "integrated platform", and the "core graphics card" seamlessly integrated with the processor ends the era of "integrated graphics card". This pioneering work benefits from the brand-new 32 nm manufacturing process. Because the processor under the framework of Sandy Bridge adopts a more advanced 32nm manufacturing process than the previous 45nm process, the power consumption of CPU is further reduced theoretically, and the circuit size and performance are significantly optimized, which creates favorable conditions for the integrated graphics core (core graphics card) and CPU to be packaged on the same substrate. In addition, the second-generation Core also added a brand-new high-definition video processing unit. The speed of video conversion and decoding is directly related to the processor. Due to the addition of high-definition video processing unit, the video processing time of the new generation Core processor is at least 30% longer than that of the old processor. The new generation of Sandy Bridge processor adopts a new interface design of LGA 1 155, which is not compatible with LGA 1 156. Sandy Bridge is a new micro-architecture, which will replace Nehalem, but will still adopt 32 nm process. What's more attractive is that this time, Intel no longer uses "glue" to stick the CPU core and GPU core together, but really combines them into one.

20 12 Beijing planetarium on the afternoon of April 24th, Intel officially released the Ivy Bridge (IVB) processor. 22nm Ivy Bridge will double the number of execution units to a maximum of 24, which will naturally bring about a further leap in performance. Ivy Bridge will add an integrated graphics card supporting DX 1 1. In addition, the newly added XHCI USB3.0 controller * * * enjoys four channels, so it can provide up to four USB3.0, thus supporting native USB 3.0. The production of cpu adopts 3D transistor technology, and the power consumption of CPU will be reduced by half. Ivy Bridge products with 22nm technology will continue the service life of LGA 1 155 platform, so users who intend to buy LGA 1 155 platform will not have to worry about interface upgrade for at least one year.

On June 4th, 20 13, Intel released the fourth-generation CPU "haswell". The pins (CPU sockets) of the fourth-generation CPU were named Intel LGA 1 150, and the motherboards were named eight series chipsets such as Z87, H87 and Q87, among which Z87 was an overclocking player and a high-end customer base. Haswell CPU will be used for laptop, desktop CEO package and DIY component CPU, replacing the current third-generation Ivy Bridge.

1. Young trees should be pruned according to the principle of "giving priority to lightness, paying equal attention to modeling and results, and promoting early yield increase". (1) 2-4-year-old young trees, under the premise of arranging backbone branches, the key point of pruning is to clean up a layer of tightly squeezed branches and straighten the tree shape. According to the planting density, the small crown sparse layer shape (less than 80 plants per mu) and free spinning cocoon shape (more than 80 plants per mu) can be popularized. Small crown and sparse layer shape: select 3-4 main branches in the first layer, clean up the dense branches that affect the growth of the main branches after selection, and clean up 1-2 branches every year, and strive to clean them up in 2 years. Free-spinning reeling shape: 3-4 small main branches are selected every year, and the spacing between the main branches is about 20 cm, and the branches that are too dense are properly loosened. (2)5-8-year-old young trees have entered the fruiting stage, and the key point of pruning is to clean up the dense branches between layers, improve the lighting conditions of the trees, and make the fruiting parts gradually transition to the backbone branches. Clean up 2-3 crowded places every year, and strive to clean them up in 3 years. After several years of adjustment and cleaning, five main branches, 1-2 auxiliary branches and 10- 13 main branches were preserved in the sparse layer of small crown.

2. Pruning of adult trees The purpose of pruning of adult trees is to "improve the illumination, improve the quality of branches, stabilize the quality and increase the yield". The key point of pruning is to remove two layers of excessively dense large auxiliary branches, large lateral branches and large branches in batches, so that the large branches remaining in two or more layers extend outward as much as possible in a whip shape, and the total branches account for less than 20% of the total branches of the whole tree, which is beneficial to the illumination in the inner room of the first floor. If the crown of the tree is on the high side, it is necessary to gradually bow your head and be happy by the strength of the tree, and the height of the tree should be controlled below 3.5 meters; If the crown has crossed, the densely packed branches should be drained or transformed into small branches, and the branches should be shortened to slow down the outside and promote the inside, or the direction and angle of the main branches should be changed by changing the main branches, so that the crown distance should be kept at about 1 m to improve the lighting conditions of the population and individuals.

Land leveling, sundries removal and deep ploughing. There are two ways:

1. Full-scale deep ploughing: Before deep ploughing, 4,000-5,000 kilograms of soil manure or farmyard manure should be sown per mu with a depth of 30-40 cm;

1. Tillage: Ditching shall be carried out according to the planting method, with a depth of 50 cm and a width of 60 cm, and the topsoil and core soil shall be set separately. 2,500-5,000 kilograms of soil miscellaneous fertilizer or farmyard manure are applied to each mu in the border, and the topsoil is returned to the field 10 cm, and mixed evenly. Digging time:11-65438+before planting mulberry in February. [5]

Planting management

1. Planting time: 65438+ February to March of the following year.

2. Planting density and form: per mu 1 0,000-10,200 mulberry seedlings. There are two forms of planting:

(1) Wide and narrow row planting: For the flat land with good water and fertilizer conditions, wide and narrow row planting is adopted and triangular transplanting is carried out in the air. It is required that the large row spacing is 6 feet, the small row spacing is 2 feet, and the plant spacing is 1- 1.5 feet.

(2) Equal row planting: terraces and gentle slopes with poor water and fertilizer conditions should be planted in equal rows, with row spacing of 4 feet and plant spacing of 1.2- 1.5 feet.

13. Variety and seedling treatment: The fertilization principle of annona squamosa is to scientifically fertilize according to the tree size and different growth stages, mainly applying organic fertilizer, combining organic fertilizer with inorganic fertilizer, and gradually moving closer to green agriculture. Generally, 1 year is applied three times, and 1 time is carried out before and after pruning in winter, combined with deep tillage and garden cleaning. The application is mainly organic fertilizer, deep digging and deep loosening, full application, all organic fertilizer, phosphorus fertilizer 80%, nitrogen and potassium fertilizer 20% throughout the year; For the second time, in the young fruit period after flowering in Xia Guo (May-June), nitrogen fertilizer was 35%, phosphorus fertilizer 10% and potassium fertilizer was 20%. For the third time, at the young fruit stage in winter (September-June, 65438+1October), 35% nitrogen fertilizer, 35% phosphorus fertilizer 10% potassium fertilizer were applied. When applying, it should generally be dug and buried, and it is not appropriate to spread it. Trenching can be ditch-shaped, annular, semi-annular, radial, etc. And according to the situation of trees, topdressing outside the roots can also be carried out, which is also a limited way to supplement the nutrition of fruits and trees.

Fruits can be covered with a layer of plastic film, hay or leaves, and then covered with soil. This method is suitable for scaffolding and mature gardens with many branches and vines. 13. Local soil burying method (covering the root neck with soil) In some areas where the absolute minimum temperature in winter is higher than-15℃, the plants are not taken off the shelf in winter, and a mound with a height of 30-50 cm is piled at the base of the plants to protect the root neck before freezing. This method is only applicable to varieties with strong cold resistance and places with the lowest temperature above-15℃. If grapes are grafted with cold-resistant rootstocks (such as Peking University and Beichun). ), it will be easier to bury them underground to keep out the cold. The depth of covering soil is generally thinner in loam and flat vineyards, and thicker in sandy soil and mountain vineyards. For some plants grafted and transplanted that year, although the lowest temperature in winter can't reach-17℃, the plants grow vigorously, fall leaves late and have many fruits, so they should be buried in time to prevent cold.

Grape root system is developed, which is fleshy root and stores a lot of nutrients, including water, vitamins, starch, sugar and other organic and inorganic components.

The function of grape root system is not only to fix the plant, but also to absorb water and nutrients from the soil and accumulate stored nutrients, which becomes the material basis for the regeneration and rejuvenation of aboveground parts.

Root characteristics of grapes

Root species

The composition and distribution of grape roots are slightly different due to different propagation methods.

Rooting line: a plant propagated by seeds, with vertical main roots and lateral roots at all levels. The taproot is developed, the root system is deep, there are obvious rhizomes and the branching angle is small.

Stem root system: Branched plants have no vertical straight roots and are mainly composed of lateral roots at all levels. There is no true rhizome, the lateral roots are developed, and the root branching angle is large.

Root distribution

Grape roots are generally distributed in soil with a depth of 20~60 cm, and the deepest part can reach about 2 meters, but the depth is directly related to fertilization depth, soil quality and variety. Because the growth of roots is water-oriented, fertilizer-oriented and geotropic, the deeper the fertilization, the deeper the roots will be, and vice versa.

Growth characteristics

Grape roots can grow all year round when the soil temperature is kept at 13 ~ 25℃ and the water content is suitable. Generally speaking, grapes have a rooting peak in spring, summer and autumn, and roots and new shoots grow alternately.

The first peak: before and after grape germination, when the soil temperature is low, the root system grows slowly by absorbing water and nutrients, reaches the growth peak after leaf spreading, and then gradually decreases, reaching the lowest point in the first half of flowering.

The second peak: after the grapes set, the demand for nutrients of the whole fruit tree reached the peak of the annual demand, so the corresponding root growth also reached the peak of the annual growth, and then gradually decreased to a low peak with the maturity of the grapes.

The third peak: after the grapes are picked, the vines start to grow again, and the corresponding roots gradually resume to grow, reaching a new peak, and then gradually decrease and enter the winter dormancy period.

Factors affecting the growth of grape root system

Grape root growth is related to temperature, light, moisture, nutrition, soil pH and organic matter content.

temperature

The optimum temperature for grape root activity is 2 1~24℃. When the soil temperature reaches 8~ 10℃, the roots begin to move and grow at 12~ 13℃. When the soil temperature reaches 20~25℃, the root system enters the vigorous growth period. When the soil temperature exceeds 25℃, the root system growth is inhibited, and it stops growing when it exceeds 28℃, and it quickly becomes cork with the continuous increase of temperature.

Grape roots are weak in cold resistance and stop growing at 10℃. Generally, the roots are slightly frozen at -4℃ to -5℃ and freeze to death at -6℃ for about two days. Different populations have different resistance to low temperature, and the order is:

East Asian population (Vitis amurensis):-15℃ ~-16℃;

North American population (Peking University):-12℃ ~-13℃;

Mixed species of Europe and America (Kyoho):-7℃ ~-8℃;

European species (red soil):-4℃ ~-5℃;

moisture

The soil moisture suitable for root growth is 60%~80% of the maximum field capacity. Soil moisture and nutrient status and their related physical and chemical characteristics play a decisive role in root growth.

Excessive soil drought: it is difficult for roots to absorb water and nutrients from the soil, photosynthesis is weakened, old leaves are easy to turn yellow and fall off, and even plants wither and die.

Soil waterlogging or high water content: causing soil hypoxia, forcing roots to supplement oxygen by leaves. Over time, the roots have difficulty breathing and lack oxygen to rot. At the same time, soil hypoxia affects microbial activities, making it difficult for roots to absorb nutrients, making trees gradually weak, and root growth tends to stop or wither or even die.

Tree nutrition

The growth of grape root system is related to the nutrient supply of the tree, and the balance of leaf-fruit ratio or light load is beneficial to rooting; The heavy load consumes a lot of nutrients, which is not conducive to rooting.

If the high yield meets the weak tree stage, the yield must be reduced first, and then the nutrition should be supplemented appropriately. At the same time, the sea elf biostimulant should be applied to promote the root growth and balance the nutrient absorption.

Fertilize soil or land

The roots of any plant have a procreation tendency. Generally speaking, fertilization on grapes is beneficial to rooting. However, if we do not pay attention to fertilization methods, it will not only promote the growth of roots, but also damage the roots.

Excessive fertilizer concentration: physiological water in the tree oozes out to the periphery of the root system to balance the physiological concentration inside and outside the root system. If too much physiological water seeps out, the tree will wither or die due to physiological dehydration, which is often called "fat burning root".

Fertilization: It is easy to cause the root system to float. The soil surface layer at 20cm is rich in microorganisms and various pathogenic bacteria, and the probability of root infection will greatly increase after the root system floats. At the same time, the ability of cold tolerance, drought tolerance and waterlogging tolerance of root system decreases, which affects the tree potential, causes the quality of fruit trees to decline and is easy to crack.

Timing of fertilization: At the peak of grape root growth, timely fertilization can promote root growth and enhance tree potential. It is worth noting that after spring germination, the soil temperature is low and the root activity is poor, so it is not suitable for a large number of topdressing. A small amount of available nitrogen fertilizer can cooperate with sea elf biostimulant to restore root activity. At the same time, spraying sea elf (foliar type) on the leaves after unfolding can quickly supplement the nutrition of trees and improve the photosynthesis of leaves.

soil acidification

Soil acid damage is characterized by stiff plants, slow root growth, slow leaf emergence, small and few leaves, increased soil-borne diseases and easy occurrence of nematodes.

Root growth is poor in acidic environment, including black root, rotten root, dead root and no white root.

After soil acidification, the absorption efficiency of grapes to nitrogen, phosphorus, potassium, calcium, magnesium, boron and other nutrients becomes low. Cause nutrient loss or waste, and still lack fertilizer after fertilization.

It is easy to cause soil hardening, resulting in less air and more gaps in the soil, which is not conducive to root growth and nutrient absorption.

The number of beneficial bacteria and organisms is reduced, which is easy to breed pathogenic bacteria and nematodes.

To reduce acid damage, it is necessary to control the amount of nitrogen fertilizer and reduce the use of other acid fertilizers, such as calcium superphosphate, phosphogypsum and immature organic fertilizer. In view of soil acidification, grapes can use sea elf biostimulant containing mineral humic acid and seaweed extract in the growing period to balance soil pH value and improve soil microenvironment.

organic matter

Soil with high organic matter content and good aggregate structure has good permeability, high fertility and vigorous microbial activity, which is most conducive to root activity and growth.

For the soil with heavy clay, less organic matter and poor permeability, organic fertilizer should be added to improve it, combined with biological bacterial fertilizer and sea elf biological stimulator, and ditch drainage should be carried out to promote root growth. [ 16]

Fresh storage

Modern storage mostly adopts controlled atmosphere refrigeration, and the equipment is more complicated. At present, simple storage methods are mainly used in rural areas, such as cellar storage, cylinder storage, sulfur dioxide fumigation storage, micro-cold storage and so on.

(1) The experience of storing grapes in northern China is harmful. Generally, a cellar is built on the hillside or the source bank, with 4-6 layers of wooden scaffolding, and L layers of grape ears are gently placed on each layer. The specific methods of cellar management are as follows: ① Pre-cooling grapes in the shade for 2 days after harvest, and the pre-cooling temperature must be controlled below 65438 00℃ to fully radiate the heat in the field. Then carefully put the grapes on the shelf in the cellar. ② Control the temperature and humidity in the cellar. Due to the high outdoor temperature in the early stage of cellar, ventilation measures can be taken to keep the temperature below 65438 00℃. After winter, when the temperature drops, it can be kept at 0- 1℃ during the day and closed at night. The relative humidity should be 80%-90%, and when the humidity is insufficient, water can be sprayed on the ground to moisturize. When the outside temperature drops below 10℃, the cellar door should be closed. (3) Strengthen inspection, and timely eliminate rotten grains of diseased ears.

⑵ When the number of grapes stored is small or the grapes are stored in the courtyard, the storage method can be adopted. In the north, household urns are commonly used or stored by themselves. Before storage, wash the jar, dry it, and then put in the grapes. The method of filling the ear is as follows:

1. Young trees should be pruned according to the principle of "giving priority to lightness, paying equal attention to modeling and results, and promoting early yield increase". (1) 2-4-year-old young trees, under the premise of arranging backbone branches, the key point of pruning is to clean up a layer of tightly squeezed branches and straighten the tree shape. According to the planting density, the small crown sparse layer shape (less than 80 plants per mu) and free spinning cocoon shape (more than 80 plants per mu) can be popularized. Small crown and sparse layer shape: select 3-4 main branches in the first layer, clean the dense branches that affect the growth of the main branches after selection, and clean 1-2 branches every year, and strive to clean them up in 2 years.

Root knot nematode

Disease symptoms: after injury, the aboveground parts of crops grow slowly, the leaves are yellow and dull, and the internodes become shorter like lack of fertilizer and water; There are many milky white nodules in the underground root system, which turn yellowish brown to dark brown in the later stage. In severe cases, the roots rot and the whole crop dies.

Prevention and control methods:

Improve the soil and apply more organic fertilizers (such as cooked human and animal manure, humic acid, amino acids, etc.). ).

Often turn over the soil and dry the land, and destroy underground eggs through farming operations and direct sunlight.

Chemical control: at the beginning of the disease or in March and April every year, 10,1/0.8% avermectin 3000 times solution +40% phoxim 600 times solution or 3% ground worms kill the stars (4 kg per mu).

poultry rearing

Bacterial leaf sheath rot

Symptoms: At the early stage of the disease, there are waterlogged spots on the petiole, some leaves break from the waterlogged petiole, there are irregular waterlogged spots on the petiole, the veins are yellow and the veins are soft. In the middle stage, the tip of the leaf began to turn yellow and gradually spread inward, and then the petiole turned yellow, softened and began to rot. In a few days, the whole banana quickly turned yellow, the leaf sheath rotted and stinked, and the surface was somewhat saprophytic.

Prevention and control methods:

Adjust the planting density appropriately.

Chemical control

Roushuitong 3000 times +3% Kejunkang 1000 times spray (mainly sprayed on pseudostems and petioles).

Meat and water are sprayed 3000 times +2% kasugamycin 400 times +20% diclazole 400 times (mainly on pseudostems and petioles).

77% Keith Downing 500-fold solution or copper sulfate 500-fold solution was used for root irrigation, and the dosage of each plant was 1 ~ 2kg.

Heart rot

Banana bacterial heart rot

Symptoms of the disease: The disease infects the base of banana pseudostems, making the base black and rotten, giving off a bad smell when it is serious, and there are a lot of maggots and flies. The aboveground parts grow slowly or stop growing, and the leaves turn yellow. With a gentle push, you can make bananas lodging.

Prevention and control methods:

Cover the ground with straw at high temperature to avoid burning the base.

Clean up the seriously ill plants in the field in time and sprinkle lime on the diseased plants.

Pay attention to avoid the spread of labor tools when diseases occur in the field.

At the initial stage of the disease, root irrigation with 3% Kejunkang 1000 times or 77% Keith Downing 600 times +90% neophytomycin 2500 times was used to promote plant growth.

Mosaic heart rot

Symptoms and characteristics: It is a plant-wide disease. The leaves of diseased plants are faded with green stripes, showing typical mottled leaves and slightly swollen or necrotic veins. There are dark brown necrotic stripes or plaques on the inside of the pseudostem, and the diseased plant shrinks or even dies.

Chemical control method: spray aphid killer regularly to eliminate the virus transmission medium.

Other prevention and treatment: choose disease-free and healthy tissue culture seedlings and don't transfer them from the ward; Sucking seedlings as seedlings; Keep the garden clean, remove the diseased plants in time and destroy them centrally; And sprinkle lime in the diseased plant area for disinfection; Strengthen fertilizer and water management without applying nitrogen fertilizer; Rotation with crops such as sugarcane, rice, soybean or peanut. ? [4]?

withered

Symptoms and pathogen characteristics: Banana Fusarium wilt, also known as yellow leaf disease, is internationally known as Panama Fusarium wilt, which mainly invades vascular bundles. The diseased plant has yellow leaves, soft petiole base, withered leaves and drooping leaves, and in severe cases, the whole plant leaves droop and die. The longitudinal section of the diseased pseudostem shows that the vascular bundles are brown stripes; Cross is brown spot and defensive spot.

Prevention and control methods:

Strengthen quarantine, and it is strictly forbidden to transport banana seedlings such as powdered coke and bananas from the ward.

The disease-free seedlings were cultivated by combining heat treatment with tissue culture.

Rotation for 2 ~ 3 years.

Dig out diseased plants in time and isolate and block them [diseased plants and surrounding plants should be sprayed with 20% Haoliang 1500 times or 15% friends 800 times].

Treatment methods of diseased plants:

Glyphosate was injected to kill the diseased plants, and each plant was injected with 40% glyphosate 15 ~ 20 ml.

After the diseased plants are dried in the sun, they are burned centrally.

Dig a ditch around the diseased banana garden for isolation (specification: height 80cm× width 80cm), and sprinkle lime in the ditch.

Post warning signs at the entrance of the diseased orchard.

Replant other crops, such as corn and mango.

Sugarcane moth

Harmful state of sugarcane borer: the larvae feed on the fleshy parts of leaves, leaf sheaths and pseudostems, and produce a lot of feces on the leaves after feeding.

Control method: Spraying chemicals during larval incubation. The pesticides used are 48% Robam 1500 times, 40% anmin 1500 times, 1.8% avermectin 2000 times, 10% imiquine 3000 times or other pyrethroid pesticides.

Net stinkbug

Banana net bug

Harm: smelly bedbugs concentrate on harm and suck leaf juice, resulting in a large number of taupe spots on leaves and slow growth of leaves.

Prevention and control methods: remove the seriously damaged leaves as soon as possible and burn or bury them centrally. During the larval incubation period, 10% acetaminophen is used for 3,000 times or 3% alfat for 2,000 times or 60% trichlorfon crystal for 600 times to kill 2-3 times. Spraying 10% imidacloprid wettable powder 1000 ~ 2000 times and 50% pirimicarb wettable powder 1000 ~ 1200 times.

Elephant beetle

Banana weevil

Harmful symptoms: the banana weevil feeds on the larvae in banana leaf sheaths, pseudostems or corms, which leads to glue coating in holes, yellowing of leaves, withering and gradual death of plants.

Prevention and control methods:

After the banana is harvested, plow and dry in time to destroy the underground egg pieces.

After the larvae are drilled:

Mix 15% lesburn granules with fine sand at the ratio of 1: 30, and apply them on the axils of banana leaves after stirring evenly.

Dilute 40% dimethoate with water by 500 times or 48% dimethoate by 65,438+0,000 times, and spray it evenly on the trunk.

captain

Banana butterfly

Danger state: adults eat leaves until they are disabled, and larvae roll their bracts.

Prevention and control methods:

Artificial removal of insect bracts.

Spray the larvae with chemicals from the complete incubation period to before the bracts are rolled up. 1. Remove insect buds. 2. Remove dead leaves and residual plants in winter. 3. Spraying trichlorfon 800 times to kill the first instar larvae. 4. Protect and utilize egg parasitic wasp-Trichogramma. ? [5]?

Caterpillar control

Banana caterpillars are gray-black and covered with poisonous hairs. They mainly eat leaves and petioles and eat a lot. When they occur for a long time, they do great harm and affect field work. It usually occurs in June ~ 165438+ 10.

The control method is to spray methamidophos and metronidazole (2: 1) 2500 times to kill.

Banana is a kind of beneficial fruit rich in starch. Sweet and cold, it can clear away heat and moisten intestines.

It can promote gastrointestinal peristalsis, but it is not suitable for diarrhea due to spleen deficiency. According to the principle of "heat is cool", it is most suitable for people who are hot and dry. People with hemorrhoid bleeding and people with hot and restless fetus can eat raw banana meat.

The folk prescription is more effective to treat chronic cough with banana stewed rock sugar; Cook wine with bananas as a diet. Modern medicine believes that banana can cure hypertension, because it is rich in potassium, which can balance the adverse effects of sodium and promote the growth of cells and tissues. Banana can be used to treat constipation because it can promote gastrointestinal peristalsis.

Form. When selecting, retaining and cultivating the main lateral branches of young plum trees and completing the shaping task, it is necessary to balance the tree potential, maintain the master-slave relationship of the backbone branches at all levels, and appropriately prune the backbone branches that grow too fast. The trees that bear fruit for the first time are mainly short fruit branches and bouquets. After entering the fruit, according to the strength of its growth, leave 2 ~ 3 full buds at the base for further cutting. For long branches, it can be reduced to biennial branches, so that the middle and small branches in the whole crown are densely distributed. ? [4]?

Overwintering and cold prevention

In the absence of freezing injury in winter, it is generally not appropriate to overwinter indoors, and let it overwinter naturally outdoors to improve the ability of trees to resist various natural disasters. In order to prevent freezing injury, you can choose to pour 1 time soil before freezing in sunny days, wrap the whole container with straw bags after the water seeps down, tie it tightly with ropes, or dig ditches and bury it in the leeward and sunny places. ? [4]?

Tiantuan management

Enlarge the pit, improve the soil and apply heavy fertilizer deeply. Topdressing should be based on the principle of diligent application and thin application, and more application should be made at the tip stage. Fertilizer should be diluted first and then concentrated, and the dosage will increase with the expansion of trees. Pay attention to shaping and controlling branches to cultivate high-yield tree species. In summer, the long branches are mainly picked or cut short, and the long branches growing on the trunk and main branches are thinned. In winter, dead branches, diseased branches and drooping branches are mainly cut off. ? [2]?

Fertilizer and water management

After the planted seedlings survive, they are made into terraces with shallow ditches with a width of 20 cm and a depth of 5 cm. The terraces are used for drainage, irrigation and fertilization in summer. Topdressing once every 10 day in the early growth stage, applying 25 kilograms of ammonium bicarbonate and potassium dihydrogen phosphate per mu from germination to flowering stage, and applying 25 kilograms of urea, diammonium phosphate and potassium sulfate per mu from young fruit stage to mature stage. Fertilize the fruits underground in time during the vegetative growth period, with ammonium bicarbonate or urea of 0/50 kg per mu/kloc, and apply organic fertilizer in the border or tree tray in September every year, mainly with decomposed chicken manure and circulating fertilizer. Apply 3000 kg of high-quality coarse fertilizer, 30 kg of diammonium phosphate, 30 kg of potassium sulfate and 30 kg of urea per mu, and water once after each fertilization. In the whole production process, except watering after fertilization, water 1 ~2 times according to soil moisture, and intertillage and loosen the soil at any time after irrigation. ? [2]?

Temperature and humidity control
