Kiwifruit seedlings have strict requirements on environmental conditions, so careful planning should be carried out when building gardens, such as selecting suitable gardens, planning irrigation and drainage systems, roads, windbreaks, configuring pollination trees, and selecting suitable shelves.
(A) Garden selection and planning
When choosing a garden, we should first consider the requirements of the growth and development of kiwifruit seedlings on environmental factors such as temperature, moisture and soil. Secondly, social and economic conditions should be considered, such as building a garden near the city, which is convenient for transportation and marketing of kiwifruit seedlings. The elevation of the garden site should not be too high, the groundwater level should be1.2m, and the terrain should be as flat as possible. Sandy loam with good drainage efficiency and high organic fertilizer content and pH less than 7 can be given priority.
After the park site is selected, it is necessary to plan and divide small areas according to the terrain and area, which is conducive to operation and management. There should be roads between communities, and drainage canals and shelterbelts should be arranged. Generally, about 0.67 hectares (10 mu) of plain land is divided into a community.
A rectangular shape is suitable. The mountainous and hilly areas with complex terrain can be appropriately reduced according to the terrain, and the residential area should be parallel to the contour line. There should be enough roads between communities, and a certain number of main roads, secondary roads and branches can be set aside according to the size of the orchard.
It is convenient for the operation and transportation of park management measures.
The channel design of irrigation system can match the road. In order to save water, facilities such as high-altitude sprinkler irrigation, drip irrigation under trees or surge irrigation can be used where conditions permit to ensure the water demand for kiwifruit seedling growth. It's rainy in the south of China, so the orchard drainage system is extremely necessary. At present, open ditch drainage is mostly used for flat land. The drainage system of mountain orchards is also beneficial to reduce the loss of soil and fertility caused by surface runoff.
When planning the orchard, it is necessary to set up shelterbelts on the windward side to prevent the harm of strong winds to kiwifruit seedlings, ensure their normal growth, and create good environmental conditions for bee activities during flowering to facilitate pollination and fertilization; Shelterbelt tree species require fast growth, long life, no pests and diseases like kiwifruit seedlings, cold tolerance and certain economic utilization value. When planting, trees and shrubs are mixed, deciduous trees and evergreen trees are mixed.
(2) Variety selection and pollination tree selection
1. Variety selection
There are many kinds of kiwifruit seedlings, but at present, the most economical ones are delicious kiwifruit seedlings and Chinese kiwifruit seedlings. Generally speaking, China kiwifruit seedlings mature earlier, and the fruit storability is poor, while delicious kiwifruit seedlings mature later, and the fruit storability is better. In large orchards, attention should be paid to the collocation of early, middle and late maturing varieties to avoid the concentration of varieties in a single mature period, but there should not be too many varieties in the same orchard. The production garden is not a variety garden, and each variety must have a certain production scale. Specific varieties can be selected according to local conditions and the characteristics of some excellent varieties introduced in the early stage.
2. Selection of pollination trees
Kiwifruit seedlings are dioecious, and only when the male plants are planted can the female plants fertilize and bear fruit, so pollination trees must be planted in the garden. The flowering period of male plants used as pollination trees should be the same as that of female varieties. Generally, the flowering period of male plants is required to be 1 ~ 2 days earlier than that of female plants, and it is more ideal if the flowering period of male plants is long. It is also required that male plants have strong growth potential, large flowers, good affinity with female plants and good pollination effect. The ratio of male to female plants in the production garden is generally 8: 1, which can ensure the pollination effect without reducing the production capacity.
(3) Planting
Kiwifruit seedlings are usually planted before germination in early spring or after defoliation in autumn, and the survival rate is high after autumn, and the growth is fast in the following year, but attention should be paid to the antifreeze of winter seedlings after planting. Before planting, the land should be leveled, and the best depth in the first autumn is 60 ~ 80 cm.
To build gardens on hills and slopes, we should improve the soil by digging ditches and building terraces, and make full use of the topsoil to increase fertile soil. Before planting, sufficient basic fertilizer should be applied, especially farmyard manure, 50 ~ 100 kg per hole, 0.5 kg of phosphorus, 0.5 kg of potassium and 0.5 kg of magnesium fertilizer respectively. Oil residue bean cake has a good effect on the growth and development of kiwifruit seedlings, and it is 1.5 kg per hole.
The row spacing of planting plants depends on the growth potential of varieties, soil fertility, framework, cultivation management level and mechanization degree. If kiwifruit seedlings grow well, the soil fertility is good, and the degree of mechanization is high, the orchard with scaffolding should be planted thinly, otherwise it should be dense. Generally, the row spacing is 4 meters, and the plant spacing is about 2.5 ~ 3 meters.
Carefully check the root system of each seedling before planting, cut off the damaged root system, and the seedlings planted in the same community should be uniform in size to ensure the neat growth after planting. Planting method is the same as other fruit trees. The planting depth should be the root neck and ground after watering and sinking. ......
In what season is kiwi fruit tree suitable for transplanting?
Kiwi is a perennial vine fruit tree, which needs more fertilizer. The important material basis of early fruiting, high yield, stable yield, high quality and long life depends on reasonable fertilization.
Apply germination accelerating fertilizer from the end of February to the beginning of March. You can loosen the soil around the tree tray first, then spread it, and then dig deep into the soil; Stripping applications can also be used. Generally, the ditch is about 20cm deep and covered with soil after fertilization. The amount of urea applied per plant is 0. 1 kg.
Kiwifruit planting, it is best to choose hilly and mountainous areas with loose soil, rich humus, sufficient light, sufficient water, moderate rainfall, slightly higher humidity and loose and breathable sandy loam.
In what month were kiwifruit seedlings planted?
In the traditional open seedbed, kiwifruit is usually sown in spring, and the sowing time depends on the local climate conditions. Generally, the middle and late March is in the south-central region of China, and the early April is in the north-central and northern regions.
In the middle stage, the seeds can be sown when the average temperature reaches 1 1.9℃. Sowing too early or too late will affect seed germination and seedling growth. When about 20% ~ 30% of the seeds germinate and are "exposed", it is suitable for sowing.
In greenhouse or plastic shed, the sowing date can be advanced by 1 ~ 2 months.
As for whether early April is the most suitable time, it depends on your area. If the season is suitable, the germination rate is 20%-30% in 20~30 days.
Management after sowing is very important:
Kiwifruit has small seeds and weak seedlings, and is afraid of drying, flooding and sun exposure. Therefore, it is necessary to strengthen post-sowing management to promote rapid, uniform and robust seedling emergence. To this end, special attention should be paid to:
( 1)
Spray (water) frequently.
Kiwifruit seeds are small and shallow, and the dryness of topsoil affects the germination and excavation of seeds. Therefore, water should be poured (sprayed) frequently to keep the seedbed soil moist. The standard of pouring (spraying) water should master the principles of diligence, uniformity and fineness. Watering every week in rainy days.
(Spray) water 1 ~ 2 times, or spray 1 time in the morning and evening. Spray water gently, slowly and evenly, don't wash it violently, and drain it in time when there is too much rain. For greenhouses, when the temperature is lower than 85% or the soil humidity is lower than
20%, can be equipped with spray device for spraying.
(2) When 20% ~ 30% of the seeds emerge after 20 ~ 30 days of sowing, the seeds are gradually uncovered on cloudy days or in the evening, and the seedlings are tempered by light. When uncovering grass, the action should be light and slow, so as not to uncover grass and pull out seedlings. When the eclosion reaches about 80%, it can be completely uncovered.
(3) The seedlings covered with grass in the shade shed are delicate, and direct sunlight and exposure are the most taboo. Therefore, when the grass is uncovered, a shade shed should be built in time, and the shade degree should reach 50% ~ 70%. With the growth, the adaptability of seedlings will be gradually enhanced. In order to meet the needs of their own growth, the management should gradually increase the light transmittance in time until 5 ~ 6 real leaves grow, and gradually dismantle the shade shed.
(4)
interplant
When the seedlings grow to 2-3 real leaves, it is necessary to start thinning. When thinning seedlings, master the principles of removing the weak and retaining the strong, removing the disease and retaining the right. When the seedling spacing is 3 ~ 5 cm and the true leaves grow to 4 ~ 5 leaves, the seedlings can be fixed. The combination of sparse seedlings will be too dense.
The general density can be 20 ~ 30 cm× 10 ~ 20 cm. Transplanting should be done in cloudy or evening. Water and shade after planting, and it will be the same as normal nursery management after survival and greening.
It is observed that the transplanted seedlings are generally healthy and have developed roots because of good ventilation and abundant nutrients, and the rate of reaching the grafting standard of that year is high. Therefore, it is suggested to use plastic shed, greenhouse, hotbed or nutrition bowl to sow in advance, and transplant when the seedlings grow to 4 ~ 5 true leaves, so as to achieve the purpose of more seedlings, Miao Zhuang and short seedling raising time.
(5)
Superficial application
In order to promote the vigorous growth of seedlings, topdressing can be carried out half a month after the seedlings are unearthed. Topdressing should follow the principle of "being diligent, less and even", generally spraying 0. 1% ~ 0.3% urea solution 1 ~ 2 times, and then every other time.
15 ~ 20 days 1 time, and it can also be combined with washing and smearing decomposed human feces. When the seedlings grow to 30 cm high, reduce the amount of nitrogen fertilizer and increase the amount of phosphorus and potassium fertilizer to prevent excessive growth.
(6) Loosening soil and weeding to prevent and control pests and diseases.
Master the principle of "early weeding and small weeding", loosen the soil and weed in time, and keep the border bed loose and free of weeds. Combined with weeding, the high new buds are bud-removed, vine-tied, lateral branches removed and core removed. The main diseases at seedling stage are damping-off and verticillium wilt.
Catastrophe, etc. And carbendazim should be sprayed before the onset to prevent it. Once the diseased strain is found, it should be removed immediately. The common pests in seedling stage are mole cricket, cutworm, grub and so on. It is very harmful to bite off the root neck and feed on leaves and whole plants, which should be paid attention to.
Prevention and control.
If the management is timely and proper, the fertilizer and water conditions are good, and the seedlings grow very rapidly, most seedlings can reach the grafting thickness (about 0.5 cm) in the same year.

How to plant potted kiwifruit seedlings is as follows
Kiwi is a deciduous vine fruit tree. In order to make potted plants blossom and bear fruit on the balcony, the following points should be paid attention to during cultivation:
(1) Choose fresh food species with moderate growth potential and short and compact internodes, such as Kuimi in China kiwifruit, Wuzhi No.2 and Xu Xiang in delicious kiwifruit; Others, such as ornamental and fresh kiwifruit and hairy kiwifruit, can also be used for potted fruit on the balcony.
(2) The cultivation container should be large to meet the requirements of vigorous growth of kiwifruit and high consumption of water and fertilizer by large-leaf fruit.
(3) Kiwifruit belongs to dioecious plants. In order to have normal fruit, a male plant with the same flowering period must be paired with a female plant, or a male branch must be grafted on the female plant to solve the pollination problem.
(4) Pay attention to the supply and adjustment of water and fertilizer, and keep the basin soil slightly dry in rainy season and dormant period; During the summer and autumn growth period, water frequently and keep it moist.
When will kiwifruit be transplanted?
Cultivation techniques of kiwifruit:
Time: March to April every year!
It is best to choose sandy loam or sandy soil in mountainous areas with convenient transportation, abundant sunshine, water source, moderate rainfall and slightly high humidity, or hilly areas with loose soil and rich humus as the garden. After the site is determined, roads, irrigation and drainage systems, fertilizer management rooms, etc. All of them are planned first, and then the ventilation culvert in the planting area is planned.
The main scaffolding methods used in kiwifruit planting are: T-frame, hedge frame, tripod, large shed frame and so on. Large flat-topped scaffolding is often used, and the original small-diameter trees can be used as live piles on the spot, and some replaceable bamboo and wood soil can be added, and concrete piles can be used in key parts. The height of the local frame is 1.8m, and the wires of 10- 12 are criss-crossed, forming a "well" network, and the spacing between wires is about 60cm.
When will the kiwifruit seedlings be planted?
Kiwifruit seedlings are best planted in spring.
What factors should be paid attention to when planting kiwifruit seedlings?
Kiwifruit planting should pay attention to pruning and shaping, fertilizer and water management, pest management and so on.
1, trimming and shaping. Kiwifruit grows rapidly and its branches and leaves are luxuriant. Timely pruning can promote flower bud differentiation and attack the nutrition on the fruit.
2. Fertilizer and water management, mainly based on calcium, magnesium, boron, iron, manganese and other elements, mainly based on basic fertilizer, accounting for 2/3 of the annual fertilization.
From germination to flowering and fruiting, appropriate topdressing, mainly available phosphorus and potassium fertilizer.
3. Love to prevent pests and diseases, and make it clear that diseases can be prevented and incurable. Therefore, it is very important to do a good job in pest control during the garden break. Especially for early prevention of canker and anthracnose.
When are the macaque seedlings planted?
Kiwifruit seedlings usually emerge from the nursery after falling leaves in autumn. If it is planted in autumn, you can also take out the seedlings from the nursery before the leaves fall, but you need to bring soil or pick some leaves before digging the seedlings. Seedlings are generally dug manually, and machines are used when conditions are good.
No matter how you dig, you should do as little damage to the roots as possible. When digging manually, don't rush for success, and don't worry. Shovel or hoe at a distance of 0/5-20 cm from kiwi seedlings/kloc-,and the inclination of the shovel should not be too large. We should dig out one by one according to the variety, not one plant in the east and one plant in the west. The excavated kiwifruit saplings are graded according to national standards, and each 50 saplings are bound, and then plastic or white cloth labels are attached, and the variety name and sapling grade are written on the plastic labels with a blue ballpoint pen.
If it is a white cloth strip, fill it in with a brush or a black ballpoint pen to make it clear. If someone had bought it at that time, take a sample in person and put it aside.
