There is a rooting peak, 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
Vitamin C in apples is a protector of cardiovascular system and a healthy element for patients with heart disease.
People who eat more apples are much less likely to catch a cold than those who don't eat or eat less apples. Therefore, some scientists and doctors call apples "all-round healthy fruits" or "general practitioners". The air pollution is serious. Eating more apples can improve the respiratory system and lung function and protect the lungs from dust and smoke in the air. [7]
Pectin: It belongs to soluble fiber, which promotes cholesterol metabolism, lowers cholesterol level and promotes fat excretion.
Trace elements: potassium dilates blood vessels, which is beneficial to patients with hypertension; Zinc deficiency will lead to disorder of blood sugar metabolism and decline of sexual function.
Can regulate the stomach: fiber helps to excrete; It also has astringent effect on diarrhea.
Apple peel+a few slices of ginger boiled water: it can stop vomiting.
It can reduce the coldness of pears and strengthen moistening the lungs and stomach.
Autumn lung moistening syrup: apple/pear+1 lily+Dendrobium 15g+ apricot 9...[7]
value
Apple is mild in taste, rich in carbohydrates, vitamins and trace elements, including sugars, organic acids, pectin, protein, calcium, phosphorus, potassium, iron, vitamin A, vitamin B, vitamin C and dietary fiber, and also contains malic acid, tartaric acid and carotene, which is the closest one in nutritional value among all fruits and vegetables.
zinc (Zn)
Apple has the reputation of "wisdom fruit" and "memory fruit". People have long found that eating more apples can improve memory and intelligence. Apples are not only rich in essential nutrients such as sugar, vitamins and minerals, but also rich in zinc. According to research, zinc is a component of many important enzymes in human body and a key element to promote growth and development. Zinc is also an essential element for nucleic acid and protein, which is closely related to memory. Zinc is also closely related to the production of antibodies and the improvement of human immunity.
The water content of apples is 85%.
Apples contain polyphenols and flavonoids, natural chemical antioxidants and a lot of crude fiber.
It contains more potassium, which can be combined with excess sodium salt in human body and excreted. When the human body ingests too much sodium salt, eating some apples is beneficial to balance the electrolytes in the body.
It contains phosphorus, iron and other elements that are easily absorbed by the intestinal wall, and has the functions of strengthening the brain, nourishing blood, calming the heart and sleeping.
The aroma of apples is a good medicine for depression and depression. After many experiments, experts found that among many smells, the aroma of apples has the greatest impact on people's psychology and has obvious effect on eliminating psychological depression. Clinical application has proved that the mood of patients with depression is greatly improved, and their spirits are relaxed and happy. After smelling the fragrance of apples, their depression is eliminated.
Malic acid in apples has whitening effect. Many people worry that the acidity of apples will corrode their teeth. Apples with cheese can limit the acidity in apples. Eating apples can also effectively help clean teeth.
It can be eaten raw or cooked, and can also be made into dried fruit, jam, jelly and so on. Apples are used in many sweets.
It can protect human body from harmful substances-free radicals, and help prevent many diseases related to free radicals. Anthocyanin can enhance vascular elasticity and protect the inner wall of arterial blood vessels; Lowering blood pressure; Improve skin smoothness and beautify skin; Inhibit inflammation and allergy, improve joint flexibility and prevent arthritis; It can promote the regeneration of rhodopsin in retinal cells and improve vision; It also has anti-radiation effect and so on. Anthocyanins maintain human health in many ways and bring many benefits. Therefore, when eating pitaya, try not to discard the pink peel inside. Because anthocyanins are sensitive to temperature, it is better to eat them raw. You can scrape it off with a knife and eat it raw, or you can cut it into thin strips for cold salad. Juicing is also a good choice.
It contains plant albumin and anthocyanins, rich vitamins and water-soluble dietary fiber, which are rare in general plants. Albumin is a viscous colloidal substance, which has detoxification effect on heavy metal poisoning. Due to the lack of attention to the treatment and recycling of industrial wastewater and waste, various water resources have been seriously polluted by heavy metals. In addition to direct drinking water poisoning, human food intake is also prone to heavy metal poisoning. When albumin meets heavy metal ions in the human body, it will automatically combine with heavy metal ions and be excreted by the excretory system, thus playing the role of detoxification. So eating pitaya rich in albumin can avoid the absorption and poisoning of heavy metal ions. Albumin also has a protective effect on the stomach wall. Moreover, the albumin in the flowers, fruits and stems of pitaya is very good and has excellent stability.
1, different tastes: pitaya is delicious or not, which has a lot to do with varieties. Generally, red pitaya is more delicious than white pitaya, with sugar content above 15, and sweet but not greasy taste.
2. Different nutrition: The nutritional value of red pitaya is much higher than that of white pitaya. The content of carotene in red dragon is high, which helps to improve immunity and protect the lens of eyes.
3, the price is different: the price of red pitaya is generally higher than that of white pitaya, mainly because the nutritional value of red pitaya is higher than that of white pitaya, and the taste and taste are slightly better.
1, anti-aging: Red pitaya has high anthocyanin content. Anthocyanin is an effective antioxidant, which has antioxidant, anti-free radical and anti-aging effects, and also has the functions of inhibiting brain cell degeneration and preventing dementia.
Generally, grafting can be carried out in all seasons except the low temperature period in winter. Because winter and spring are cold and humid for a long time, the wound is not only difficult to heal, but also expands, endangering the plant. Therefore, the best grafting time is March-June, 65438+1October, which has sufficient healing growth period and is conducive to the next year's results.
3. Drug treatment before grafting
The knife used for grafting should be disinfected with alcohol or white wine to prevent bacterial infection. Conditional availability. Dipping the base of scion with sodium naphthylacetate solution can not only promote the formation of callus, but also improve the survival rate. [3]
4. Grafting method
A. Docking method
In Lady Enforcers, a sharp knife is used to cut the triangular prism crosswise at a proper height, then three edges are cut at 30-40 degrees, the sterilized fairy thorn is used to pierce the vascular bundle in the middle of the rootstock, and the cut scion is connected to the other end of the thorn, and the scion is connected to the thorny rootstock. Rootstock and scion should be as close as possible without gaps, so as to avoid poor healing caused by bacterial infection. Then add a thorn on both sides to fix it, and then tie it tightly around the base with thin iron wire.
B. wedging method
Cut a slit longitudinally at the top of the rhizome with a sterilized knife, but not too deep. Then cut the lower part of the scion into a duckbill shape with a sterilized blade, insert it into the crack of the rootstock immediately after cutting, fix it with plastic tape, and cover it with a plastic bag to keep the air humidity, which is beneficial to survival. After 20 days, the growth of grafting was observed. If it can keep fresh and bright green, it will survive. You can leave the nursery in a month.
pot culture
The germination temperature of pitaya seeds is about 25℃.
To choose culture soil with fine particles, you can also use commercially available sowing soil instead.
Be sure to remove the pulp and gum attached to the seeds, otherwise mold will easily grow when sprouting.
To make a small potted plant, the seeds should be spread densely, especially at the edges, otherwise it will be scattered loosely and lose its aesthetic feeling.
If there is no bottom hole in the basin, don't water it directly with the kettle, so as not to water it too much. Just spray water with the watering can once every 2-3 days.
Including peaches, plums, apricots and cherries. The outer wall of the ovary forms exocarp, the middle wall develops into fruit meat, and the inner wall forms lignified stone. There is usually a seed in a stone. The edible part is mesocarp.
3. Berry fruit trees
Include kiwi fruit, raspberry, pomegranate, grape, etc. The fruit is juicy, and the seeds are small and numerous, which are distributed in the pulp, and most of them are not resistant to storage. This kind of fruit has great differences in fruit structure due to different tree species. Its representative tree species is grape, the fruit develops from ovary, the exocarp is membranous and the mesocarp is soft and juicy. The edible part is mesocarp.
4. Nut fruit trees
Including walnuts, chestnuts, hazelnuts, ginkgo, etc. It is characterized by a hard shell outside the fruit and seeds in the shell. Edible parts are mostly seeds, which have low water content and are resistant to storage and transportation, commonly known as dried fruits.
5. Persimmon and jujube trees
Exocarp membranous, mesocarp fleshy. The endocarp of jujube forms a nucleus, and the edible part is mesocarp; Persimmon endocarp is tough, and the edible part is the middle endocarp.
Including oranges, oranges, oranges, grapefruit and so on. The fruit developed from ovary, the exocarp was leathery with oil cells, the endocarp was a white sponge and the endocarp was a juicy sac. The edible part is endocarp capsule. Most fruits are resistant to storage and transportation.
2. Others
Include litchi, longan, loquat, bayberry, coconut, mango, avocado, etc.
Perennial herbaceous fruit trees
Include bananas, pineapples, strawberries and the like.
(1) Nutrition and health functions of fruits are rich in nutrients, including vitamins and inorganic salts, as well as sugar, starch, protein, fat, organic acids and aromatic substances, which are necessary for human growth, development and nutrition. According to nutritionists, each person needs 70 ~ 80 kilograms of fruit every year to meet the normal needs of the human body.
(2) Medicinal functions of fruits Many fruits and seeds can be used as medicine and have therapeutic effects. Such as walnuts, lychees and longan are all good tonics; Pear cream and persimmon cream are often used as medicine; Almond, peach kernel and orange complex are important Chinese herbal medicines. Guava can treat diabetes and lower cholesterol.
(3) The eco-environmental benefits of fruit trees have universal adaptability. Fruit trees can be planted not only in plains, rivers, roads and rural gardens, but also in deserts, hills and beaches. Choosing suitable fruit trees can not only increase economic income, but also prevent soil erosion, increase green coverage area and adjust climate, thus greening, beautifying and purifying the environment.
(4) Fruit trees are important raw materials for food industry and chemical industry. In addition to fresh food, fruits can also be processed into preserved fruits, fruit juices, preserves, jams, cans, fruit wine, fruit vinegar and so on. The hard shell of some fruits can be used to make activated carbon, the leaves, bark and peel of some fruit trees can be used to extract dyes or tanning materials, and orange peel and neroli can be used to extract essential oils. The wood of many fruit trees is an excellent material for national defense industry, construction industry and carving technology.
(5) Economic Benefits of Fruit Trees Fruit trees are an important part of agriculture and play a decisive role in agriculture.
Excessive drought in soil: it is difficult for roots to absorb water and nutrients from the soil, and photosynthesis of branches can shape trees. 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", and 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 number of branches accounts for less than 20% of the total number of 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.
Second, cut off the diseased branches and insect branches. According to the survey, many diseases and insect pests that harm apples overwinter on the branches. For the diseases and pests that overwinter in trees, combining with winter shears, all branches of diseases and pests are cut off, burned or buried deeply, which can obviously reduce the harm in the coming year.
Third, scraping the rough old bark In the gap between the rough old bark and trunk of fruit trees, there are often a large number of overwintering bacteria and pests. Scraping rough old bark, burning or burying it deeply has a good control effect on many kinds of pests and diseases, and sometimes even completely eliminates some pests.
Apple is a beauty product, which can not only lose weight, but also make the skin smooth and tender. Apple is a low-calorie food, every 10.
0 g only produces 60 kilocalories; The nutrients in apples are soluble and easily absorbed by the human body, so they are called "living water", which is beneficial to dissolve sulfur and make the skin smooth and tender. Apple contains copper, iodine, manganese, zinc, potassium and other elements. Without these elements, the skin will be dry, fragile and itchy.
Vitamin C in apples is a protector of cardiovascular system and a healthy element for patients with heart disease.
People who eat more apples are much less likely to catch a cold than those who don't eat or eat less apples. Therefore, some scientists and doctors call apples "all-round healthy fruits" or "general practitioners". The air pollution is serious. Eating more apples can improve the respiratory system and lung function and protect the lungs from dust and smoke in the air. [7]
Wood is an excellent material for national defense industry, construction industry and carving technology.
(5) The economic benefits of fruit trees are an important part of agriculture. With the adjustment of rural industrial structure and the liberalization of agricultural products market, especially in hilly, mountainous and desert areas, developing fruit tree production according to local conditions can bring considerable benefits to farmers. China fruit is rich in resources, and fruit tree production is highly competitive in the international market, which is an important source of foreign exchange earned by agricultural products export.
First, the selection of excellent varieties of saplings should be pure and adapt to local natural environmental conditions. To develop new varieties of fruit trees, it is necessary to consult relevant scientific research departments and experts, and never trust advertisements and choose seeds by ear. The seedlings supplied by general scientific research units and competent departments are more reliable. For seedlings sold by individuals, it is necessary to find out the source of seedlings or scions.
Illicium verum: aggregate fruit consists of 10- 14 joints. It is grayish brown or grayish brown. The skin of the fruit is thin, and the front end of the single-petal fruit is long, tapering and slightly curved. The smell is light and special, the taste is light, and it has a numbness.
Illicium verum: It consists of 10- 14 fruit. The single fruit is irregular, broadly conical,1.6-2cm long and 0.4-0.6cm wide, and the top is long, tapering and slightly curved. The peel is thin, the pedicel is about 1.5-2 cm long, and the taste is light, and it has a spicy feeling after a long taste.
Illicium verum: It consists of 10- 13 fruit. Single fruit boat, length 1.8-2.3 cm, width 1.5- 1.8 cm. Its apex is sharp, its apex is not curved, its peel is slightly thick, slightly smelly, slightly bitter and slightly spicy.
The common counterfeiting method is to break the fruit to make it difficult to identify. Then the star anise is mixed with counterfeit goods, and the true and false are mixed.
Chemical identification
Put 5g of powder of Illicium verum sample to be tested in a distillation bottle, add150ml of water, conduct steam distillation, and collect 50ml of distillate (Illicium verum distillate is milky white). Adding the same amount of ether into the distillate, extracting and separating the ether layer. Then add 30-50 ml of 0. 1 mol sodium hydroxide solution to the ether layer, shake well, and discard the alkaline aqueous solution, and repeat this for three times.
Volatilize the ether in the water bath and dissolve the residue with 2-3 ml of ether. Then drop it into the phosphoric acid solution containing phloroglucinol (1-2 mg phloroglucinol dissolved in 3 ml phosphoric acid), shake it evenly while dropping, and observe its color reaction.
After the above operations, Illicium verum changed from five colors to yellow and then to pink, and the solution was turbid. After the fake star anise turns from colorless to yellow, it can't turn pink, and the solution is still transparent.
Relatively unchanged, it can be divided into three types: exogenous, endogenous and endogenous. The cross section of pine needles is used in toothpaste, mouthwash, food and medicine. Eucalyptus globulus and Eucalyptus verticillata are excellent tree species, and eucalyptus oil is extracted from their branches and leaves with the best texture.
golden
Australian scientists used X-rays to find a trace of gold in eucalyptus leaves, which is considered to be the first time that humans have found naturally occurring gold in organisms. [ 12]
Through research, scientists found that eucalyptus and acacia trees in western and southern Australia have deep and extensive roots. During drought, their roots dig three feet to find water, and some roots touch gold veins, from which they suck a tiny part of gold. Then, the roots will dilute the gold and conduct it to the venous system of trees. After a large amount of gold material accumulates at the top of the blade, it can form larger crystals. [ 13]
Scientists further pointed out that gold is toxic to plants, so gold can be transported to the ends of plants, such as leaves, which can reduce destructive biochemical reactions. [ 12]
In addition, the researchers said that the amount of gold contained in leaves is very small, and the gold content in 500 eucalyptus leaves grown in gold mining areas may be enough to make a wedding ring, so this discovery will not bring wealth to gold diggers. However, scientists point out that this discovery will help people explore gold in a more environmentally friendly and cheap way. [ 12]
Edible
The roots of eucalyptus can be used as food or water. Some places also use eucalyptus as fuel. There are many eucalyptus leaves that can be used as feed.
Medicinal value
Fresh eucalyptus leaves can be distilled with water to produce eucalyptus oil (the oil yield is 0.5- 1.8%). Eucalyptus mainly contains cineole (65-75%). Terpene, isoprene leaf oil, carvone, menthone, piperidone, etc. It can also be used as medicinal raw materials for oral cavity, rhinitis, expectorant, cooling oil, Qufeng ointment, etc.

6. Treatment of pustular herpes and eczema: eucalyptus grandis leaves and neem bark are suitable. Wash with boiling water twice a day.
The usual dosage of this product is 9- 15g (fresh 15-30g), so it is not advisable to take it in excess. Appropriate amount for external use, decoction and external washing.
Natural value
Eucalyptus has graceful posture, evergreen seasons, rapid growth and strong drought resistance, and is suitable for street trees, windbreak and sand fixation forests and landscaping trees. The leaves contain aromatic oil, which can sterilize and repel mosquitoes and can be used to extract sesame oil. It is also a good greening tree species in convalescent areas, residential areas, hospitals and public green spaces.
Eucalyptus plantation is also a huge carbon pool. According to research, eucalyptus can absorb 9 tons of carbon dioxide per hectare and release oxygen at the same time. Planting eucalyptus on degraded land can improve soil structure, increase soil biomass, improve microclimate and change the ecological environment of afforestation area. Leizhou Peninsula used to be thousands of miles away, the environment deteriorated, and the forest coverage rate was only 8%. Since 1954, a large number of eucalyptus plantations have been built, with nearly 3 million mu of eucalyptus and a forest coverage rate of 24%. The ecological environment has obviously improved and it has become an important agricultural city in the south subtropical zone.
The mixed forest of eucalyptus, Sophora japonica and poplar can make full use of land resources and light energy resources to maximize economic benefits.
Mixed forests are mixed and matched according to the characteristics of plants like light and shade tolerance, root rooting depth, plant growth cycle, and fertilizer preference, so as to make full use of land resources and rationally distribute light, water and nutrients at different levels. Another feature of the mixed forest is that the light in the forest is weakened and the water evaporation is reduced, which can form a microclimate mixed forest with more developed roots and more effective water conservation, wind prevention and sand fixation. Mixed forest has thick crown, more litter and more leaves per unit area, which can improve soil fertility more than simple forest. Mixed forest has many varieties, good habitat and many natural enemies of pests and diseases, which can effectively inhibit the propagation and spread of pests and diseases; Because of the low temperature, high humidity and low wind speed of mixed forest, the risk factor of fire is low; The main tree species of mixed forest, with the help of associated tree species, grow more generally and roundly, and have better dry wood quality.
High quality wood
Eucalyptus wood is heavy and hard with strong corrosion resistance, and can be used in buildings, sleepers, columns, piles, furniture, matches, farm tools, poles, fences, carbon materials and so on.
It is very effective in delaying aging and inhibiting pigmentation.
Antiemetic fruit: aromatic lemon "suitable for mother and child" to eliminate morning sickness
Cantonese, a work of traditional Chinese medicine in Guangdong and Guangxi, records: "Lemon is suitable for mother and child, and tastes extremely sour. Pregnant women are addicted to it because of liver deficiency, so it is suitable for mother. It is better to hide more than old when people bid, and juice can replace vinegar. " In other words, pregnant women can put some lemons beside the bed and get up in the morning to smell them, which can eliminate morning sickness.
1. Fresh lemon can be drunk directly: clean the fresh lemon, cut it into 2mm thick slices, put it into a cup to brew cold water after removing seeds, and add a proper amount of crystal sugar to drink.
2. Making sugar-stained lemons: After cleaning, slicing and removing seeds, put the lemons into a porcelain jar or porcelain bottle with a layer of lemon and a layer of sugar according to the ratio of 1 kg of lemon slices and 2-3 kg of sugar, and drink them one week later (diabetics can use salting, the method is the same as sugar-stained, and the salt content is 25-30% of the amount of lemon).
3. Lemon is used for cooking: when cooking fishy food, fresh lemon slices or lemon juice can be put into the pot before taking the pot, which can remove fishy smell and get tired. Seasoning with fresh lemon juice instead of vinegar is delicious and nutritious.
4, lemon fresh fruit beauty: after washing and slicing the lemon, put it in cold boiled water for 3~5 minutes, which can be used for applying face, wiping body and washing hair. Long-term use can melt the spots on the face and body, and achieve the effect of hair like an ink waterfall, face like beautiful jade, body like coagulated fat and radiant.
5. Lemon sterilization: slice fresh lemon fruit and rub herpes directly for 2-3 times to recover; Soaking feet for 2-3 times can cure beriberi.
6. Lemon deodorization and preservation: putting 2-3 fresh lemons naked in the refrigerator or living room can play a very good role in removing the odor of the refrigerator or living room; Slices in a pickle jar can remove white and make pickles crisp.
instructions
1. Although lemon has the function of strengthening the spleen and promoting digestion, it is not suitable for people with gastric ulcer and hyperacidity.
2. Patients with dental caries and diabetes should avoid eating lemons.
There are many cosmetic effects of lemon, and there are also many ways to make rational use of each part of lemon.
In the process of making lemon mask, it is often impossible to use up the whole lemon, which can be said to be a waste of resources. In fact, lemons are full of treasures. People can make full use of the beauty effects of various parts of lemon to make a perfect beauty for the whole body.
Lemon is one of the most medicinal fruits in the world. Its main functions are: anti-acid, anti-sclerosis, anti-bad blood, anti-neuralgia, anti-rheumatism, anti-itching, anti-bacteria, anti-calculus, sterilization, flatulence removal, purification, diuresis, softening, wart treatment, fever reduction, hemostasis, liver benefiting, blood sugar lowering, blood pressure lowering, insecticidal, diarrhea relieving and stomach benefiting. Arteriosclerosis, anemia, hemostasis, immune enhancement, headache, migraine, nosebleeds, sore throat, fever, cough, liver detoxification, constipation, arthritis, rheumatalgia, oily skin, pigment decomposition (anti-plaque), regenerative wrinkle removal, cellulitis, herpes and scar promotion. It also has the functions of dissolving food, relieving alcoholism, losing weight, moistening skin, caring skin and eliminating peculiar smell.
Essential oil can be extracted from the skin, leaves and flowers of lemon. Lemon embryos can be used to make preserves, jams, cakes and wines after being squeezed. Lemon juice can be made into drinks, tea and various condiments, which are fragrant and delicious.
Lemon juice is a delicious and refreshing drink, which is very simple and convenient to make. Fresh fruit is squeezed directly from fruit juice, then mixed with sugar, ice cubes and ice water, and can be drunk after stirring. That faint sweet and sour, faint fragrance is refreshing.
