When it comes to strawberries, many people should be familiar with it. It is a common fruit in our daily life. It is liked by many people because of its delicious, red and tender appearance and juicy pulp. It is cultivated in all parts of our country, but the yield of strawberries planted by some growers is not high. So the editor would like to introduce to you the seven main points of strawberry cultivation:

1. Main point 1: choose a place

Strawberries should not be planted in places with low terrain and uneven ground, but the soil with strong drainage and irrigation capacity, loose soil fertility, good water retention and good permeability is the most suitable for strawberry planting. Strawberries are suitable for growing in acidic or neutral soil. Excessive alkali will hinder the development of strawberries, and the previous crops in the soil should choose watermelon crops as far as possible.

2. Point 2: land preparation

After selecting the land, all the weeds in the land should be removed and then disinfected. After 3-5 days of sun exposure, sufficient agricultural machinery fertilizer should be applied, and the amount of base fertilizer should be determined according to the land area, usually 5000 kg per mu and then mixed with a small amount of calcium superphosphate and potassium chloride. After applying the base fertilizer, tillage will be carried out to mix the base fertilizer with the soil evenly to improve soil fertility, and finally make the bed to facilitate strawberry growth and later management.

Third, the third point: planting

The planting method has a great relationship with the growth and management of strawberry in the later stage. During planting, it is necessary to ensure that the growth direction of each plant inflorescence is the same, the number of plants in each hole should not be more than one, and the planting depth should not be too shallow and too deep, and the planting density should be reasonably controlled. Planting density should not be too dense and too thin according to planting area and soil fertility.

Fourth, main point four: watering

Strawberries like water, so they should accumulate enough fixed root water after planting, and then irrigate the soil once every 5-7 days to ensure that the soil will not be dry. In the process of growth, sufficient water should be ensured to promote plant growth. Strawberries need a lot of water when they are in flowering stage. If they are not watered in time, they will lead to serious flower and fruit drop in later growth, thus reducing yield.

5. Point 5: topdressing

Strawberry needs more nutrients for growth, especially during and before flowering and fruiting period, so it is necessary to apply sufficient base fertilizer and then apply fertilizer properly according to the actual situation during growth. For example, during the flowering and fruiting period, the fruit expansion period and the final ripening period are the peak periods of fertilizer demand. At this time, fertilizers such as diammonium phosphate and potassium dihydrogen phosphate can be properly applied to increase yield. When topdressing, it is necessary to ensure a comprehensive and reasonable proportion of nutrition in order to effectively promote growth.

Point 6: temperature

Strawberry is a kind of temperature-loving fruit which is also sensitive to temperature changes. in the planting process, it is necessary to reasonably control the growth temperature around strawberry and strengthen temperature management. the most suitable temperature for strawberry growth is about 22-25 degrees. If the range of 5-30 degrees is more than 5-30 degrees, the growth of strawberries will be greatly hindered, so it is necessary to maintain the surrounding temperature balance to make strawberries grow better.

7. Point 7: management

Regularly inspect the orchard to remove the old leaves, withered leaves and diseased leaves in time, and clean up the fallen flowers and fruits and bring some diseased fruits out of the orchard for treatment, which can properly control the growth of plants to prevent excessive growth, and then do a good job in orchard drainage and irrigation. watering the orchard in a dry and rainy day to prevent stagnant water in the orchard, reducing the humidity of the orchard as far as possible to prevent the emergence of rotten roots and fruits and affecting the yield, in addition, the greatest harm to strawberry yield is caused by diseases and insect pests. For example, leaf spot and anthrax are common diseases, so it is necessary to do a good job in the prevention and control of diseases and insect pests.

Summary: the above is the introduction of the seven key points of strawberry high-yield planting. Growers can refer to the above seven points when planting, hoping to help friends in need!

Planting techniques and key points of cultivation and Management of Strawberry

Strawberry, also known as raspberry, raspberry, raspberry and so on, is a kind of red flower and fruit. Strawberry is a general name for strawberry plants of Rosaceae, which belongs to perennial herbs. Strawberries have a heart-shaped appearance, delicious red and tender, succulent flesh and a special rich fruit aroma. Strawberries have high nutritional value and are rich in vitamin C, which can help digestion. At the same time, strawberries can also strengthen gums, refresh breath and moisturize throat. People's anger tends to be exuberant in spring, and eating some strawberries can inhibit it.

In addition, strawberries had better be eaten after meals, because they contain a lot of pectin and cellulose, which can promote gastrointestinal peristalsis, help digestion, improve constipation, and prevent hemorrhoids and bowel cancer. The nutritional ratio of strawberries is very reasonable, in which the content of vitamin C is about 10 times that of the same amount of watermelons, grapes or apples. In addition, strawberries are rich in iron, fructose, glucose, citric acid, malic acid and so on. For lung heat cough, sore throat and long fire boils that are easy to appear in spring, the nutrient elements contained in strawberries can play an auxiliary role. At the same time, because of iron, anemic friends can also eat often. But doctors also suggest that although strawberries are good appetizers, they are cold, so don't eat too much at one time in early spring, especially for people with spleen and stomach deficiency and cold, diarrhea and excessive stomach acid.

General situation of production and cultivation

Strawberries are cultivated in most countries in the world at present. Strawberry cultivation in the United States covers an area of 23000 hectares, with a yield of 567000 tons, accounting for about 28 percent of the world's total output, with an average yield of 24.6 tons per hectare. Japan has a cultivated area of 11000 hm2, with a yield of 218000 tons, accounting for 11% of the world's total output, with an average yield of 19.3 tons per hectare. Europe is the main producer of strawberries, accounting for about 50% of the world's production. Poland, Italy, Spain, the Netherlands, Belgium, Russia, Romania and the United Kingdom have a large cultivated area, with a yield of 9.5-18.3 tons per hectare. China is the country with the most abundant wild strawberry resources in the world. It began to use wild strawberries a long time ago and has been following it until now. The cultivation of large fruit strawberry in China began in 1915, but it was neglected and developed slowly in the past. Strawberry production has developed rapidly since the 1980s. At present, the area of strawberry production in China is about 70, 000 hm2, ranking first in the world. The main producing areas are located in the eastern coastal areas such as Anhui, Liaoning, Hebei, Shandong, Jiangsu, Shanghai and Zhejiang. In recent years, Sichuan, Anhui, * *, Beijing and other regions have also developed rapidly. Key strawberry producing areas are Jiangsu Sihong, Anhui Hefei, Liaoning Dandong, Hebei Baoding, Shandong Yantai, Shanghai suburbs, Sichuan Shuangliu, Jiangsu Lianyungang and so on. Changfeng County, Hefei currently has 145000 mu of strawberry planting area, with an annual output of more than 200000 tons of strawberries, with a total output value of more than 1 billion yuan, expanding to more than 200000 mu by 2012, and building the only national virus-free strawberry science and technology park in the country. Every year, promotion meetings are held in the Great Hall of the people in Beijing and the Diaoyutai State Guesthouse in Beijing, and dealers and strawberry households are held in Beijing Xinfadi Market, Tianjin Red Flag Market and Shenyang Fruit Wholesale Market. Its production scale has jumped from the top of Anhui Province to the largest county of strawberries in the country, and Changfeng Strawberry has become a well-known trademark in China.

Growth condition

Strawberries are suitable for growing in sunny, hydrophobic soil. The depth of the soil is about 8 mi 10 inches. For large strawberries, the row spacing should be 12 inches and the plant spacing should be about 18 inches. The vines of the plant should be removed in time to facilitate the fruit of strawberries. The yield of strawberries is periodic, so it is best to cultivate some new plants in the first few years of planting. If you don't like managing strawberries, you can plant strawberries every 18mur24 inches so that strawberries can grow everywhere. Of course, it will look a little messy, and the strawberries are not big. If you want to avoid this situation, you can remove some vines properly. In autumn, cover the plant with a layer of soil to prevent frost. After the soil is frozen, the plant can be covered with hay 4 inches thick. In the spring of the following year, when new leaves grow, the hay is removed. After the weather becomes warm and stable, the covered soil on the surface of the plant is removed. But leave some hay between the rows to prevent the growth of weeds and retain moisture in the soil.

Planting technology

Strawberry ranks first in the production of small berries in the world. Strawberry is an economic crop with quick fruit, early maturity, easy reproduction, short cycle and high benefit.

1. Preparation of breeding grounds

1) choose paddy fields with convenient drainage and irrigation, which are not easy to accumulate water and have high fertility, or vegetable garden soil (former crops and soil blocks that have used Lvhuanglong herbicide). Apply sufficient basic fertilizer (cake fertilizer, household fertilizer, human feces and urine, phosphate fertilizer) after ripening, at the same time, use 50% phoxim or 3% furan per mu, mix 25 jin of fine soil, and turn the soil to make a bed. The bed is 1.5 mi 1.8 meters wide and the turtle's back is shaped to prevent stagnant water and the soil should be broken.

2) selection and colonization of each plant. Select the new leaves to develop normally, the leaflets are symmetrical, the leaf color is dark green, the petiole is thick, the leaves are large, the growth is strong, the yield is good, and the diseased leaves and old leaves are removed. Our city is generally planted in the breeding ground in April of the Gregorian calendar (the daily average temperature is above 12 ℃). Two rows were planted in each border, 30 cm away from the edge of the border, and the distance between plants was 60 mi 80 cm. Immediately after planting, water the plant and fix it.

3) Fertilizer and water management, the principles of fertilization in seedling land are as follows: suitable nitrogen, heavy phosphorus and potassium, 200 jin of rotten vegetable cake plus 8 jin of urea per mu, 50 jin of phosphate fertilizer and 10 jin of potash fertilizer, and watering every 20 days after the water is dissolved. Human feces and urine can also be replaced.

4) after each plant survived (a week later), gibberellin (920) was sprayed, that is, each gram of "920" was mixed with water of 40 kilos and 50 jin, (920 was first dissolved in a clean bowl with high concentration of liquor). Spray twice at intervals of one week to 10 days. The application of nitrogen fertilizer should be strictly controlled in August to make it drought properly, but not too much.

2. Preparation and specification of timely transplanting and transplanting land.

1) Field preparation: choose fertile fields or soil with convenient drainage and irrigation as field land. Strawberries need a large amount of fertilizer, and there is generally less fertilizer in the later stage (harvest period), so the base fertilizer should be sufficient, and it should be dominated by organic fertilizer, generally 1500 tons per mu of organic fertilizer, 50 tons of cake fertilizer, 25-30 tons of compound fertilizer, 7.5 grams of urea, 40 grams of excess calcium and 10 grams of potash fertilizer. in addition to urea and compound fertilizer, other fertilizers, except urea and compound fertilizer, mix well with urea and compound fertilizer to spread the soil surface, and then turn the soil to make ridges. Generally, the height of the ridge is 25 tons, the width of the bottom of the ridge is 90 tons, and the surface of the ridge is 60 inches. The width of the ridge and trench is 30 cm, and the width of the furrow at the bottom of the ridge is about 100m / w. There is a certain inclination from the surface of the ridge to the bottom of the ditch.

2) planting period and mode: the protected cultivation in our city is generally transplanted from the end of September to the beginning of October. The planting density and seedling condition, soil fertilizer and thinness were treated separately, and strong seedlings, dry seedlings and soil fertilizer should be sparsely planted. On the contrary, it should be closely planted. Generally, 9,000 plants are planted in 7 mu. After the ridge is planted, it will be planted 5 cm from the edge of the ridge, with a distance of 12 cm to 15 cm. The length of the ridge generally does not exceed 30 meters.

Attention should be paid when transplanting: first, directional transplanting: both bow back outward, which is beneficial to the extraction of inflorescences later. Second, double-row triangular (zigzag) planting, which is conducive to ventilation and light to take root. The third is to grasp the depth so that the roots are not exposed and the seedlings are not buried at the top, which is beneficial to tillering. Fourth, transplanting with soil is beneficial to survival. Fifth, it will be planted in the afternoon on sunny days and all day on cloudy days. Sixth, strengthen the management of water and fertilizer, immediately pour through the fixed root water after planting, and add methyl topiramate according to 800 times liquid when watering. Seventh, check and replenish seedlings in time.

3. Field management

1) pre-winter management, after planting survived to mid-late November, we should pay attention to three points: first, frequent application of thin fertilizer, mainly nitrogen fertilizer, preferably dilute manure water; second, keeping moist; third, weeding and loosening soil to pick old leaves and diseased leaves.

2) pre-and post-flowering management: before flowering, young fruit stage and fruit expansion period, vegetable fruit Zhuangtieling was sprayed in time to improve the cyclic fruit setting rate of strawberry, promote fruit development, and control diseases and insect pests with topzine, Sukeling and dimethoate at the same time.

3) overwintering management: before the cold winter comes, it is necessary to pour water thoroughly to prevent the cold.

4. cover the film at the right time

Plastic film mulching can double the yield, reduce fruit loss and prevent pollution. The film is divided into greenhouse cover film and mulch film. The time of covering the film should be controlled when the daily average temperature drops to about 8 ℃. First cover the greenhouse film, then cover the plastic film. Weeding, ploughing and fertilization should be done before mulching to control diseases and insect pests. (greenhouse production and film purchase model) due to limited space will not be introduced, interested parties please contact the Agricultural Science Institute. After covering the film, the temperature in the shed should be kept at 8 ℃ at night and about 20 ℃ during the day. The film should be lifted at noon on a sunny day and covered at 3 p.m. If the temperature is too high, the pollen dies, and the activity of the pollen is not enough to pollinate.

5. Planting in greenhouse

Strawberries planted in greenhouse in early spring can blossom and bear fruit.

6. Open-field cultivation techniques

Strawberry can be cultivated in open field in two ways: one plant a year or one plant for many years. The former can be rotated with other crops after harvest every year. Under this system, strawberry has strong vitality, good fruit quality, early ripening and less diseases and insect pests. However, the key technology is to cultivate strong seedlings with more than 3 leaves and well-developed roots, which can be planted closely. Once planted, harvested for many years, transplanted in autumn, and harvested in May of the following year. After 3 years, it was renewed once with stolon seedlings.

1) applying basic fertilizer for land preparation

Strawberry has shallow roots and is suitable for growing in loam or sandy loam with good permeability and rich in organic matter. Wheat, legumes, melons and vegetables are suitable for the previous crops. It can also be intercropped with high-stem crops. Plough the land deeply early, apply manure and base manure with full rot heat of 3000kg per mu, and burn in the sun. Diammonium phosphate 25kg was applied during soil preparation. Potassium chloride 10kg. Irrigate a small amount of water before planting.

2) colonization

Seedlings with 5-6 compound leaves, strong plants and complete roots were selected before transplanting and planted in the field in cloudy days or in the evening. The planting density is (20-25) cm × (25-30) cm. The degree of planting seedlings is that the roots are not exposed and the seedlings are not buried. After planting, the seedlings are irrigated once. After the water is dry, the condition of the seedlings is checked in time to loosen the soil, cultivate the soil or replenish the seedlings. When planting, the seedlings grow with the bow back to the flat border, which is easy to manage and harvest fruit.

3) Field management

After strawberry planting, watering the root water, keeping the field moist, lowering the ground temperature, and irrigating according to the humidity in the field. When overwintering water was irrigated, 15-20kg/ mu compound fertilizer was applied to improve the overwintering ability. The flowering and fruiting period in spring is a water sensitive period, so the soil should be kept moist. When applying nitrogen and phosphorus compound fertilizer or foliar spraying fertilizer during irrigation, the water should not be too much, and the stagnant water should be discharged in time. At the same time, vegetable and fruit Zhuangtieling should be sprayed before flowering, young fruit stage and fruit expansion period, so as to improve the fruit setting rate of strawberry cycle and promote fruit development. Strawberries should be ploughed and weeded frequently after transplanting. Cultivate the soil at the right time after fruit harvest. Appropriate ground cover should be taken when overwintering, so as to prevent cold and heat preservation, and keep strawberries survive the winter smoothly. Now, more than plastic film mulching from the end of January to early February can promote the early ripening of strawberries and prolong the harvest time.

Nursing care of strawberries

Once the strawberries begin to bear fruit and turn red, be careful not to let the birds peck at them, because birds are easy to find red things. Connect a net to the strawberries or cover the strawberries with a wooden basket. But if you have a greenhouse at home, you can move the strawberries to the greenhouse, which will be better. Strawberries are also easier to bear fruit. When the fruiting period of strawberries is over, you can move them out of the greenhouse and leave them outside for the winter.

In a way, if strawberry plants are subjected to some frost, it will be more beneficial to increase yield in the coming year. Strawberries are easy to grow and can be transplanted. Sometimes you may find that the plant has yellow leaves, but don't worry, just remove it. In winter, you can keep the yellow leaves until new leaves grow in the following spring, then remove the dead yellow leaves, and pay attention to watering, weeding, and killing insects. Strawberries can also be planted in plant bags, but they must be watered evenly to prevent birds from pecking at strawberries and insect pests. The soil in the plant bag dries easily and needs to be checked frequently to make sure the soil is moist. If it is a small amount of planting, try not to use pesticides, you can use a large amount of dishwashing detergent mixed with water to spray; you can also put some melon peel, beer and so on nearby to ward off mollusk pests such as snails.

Prevention and control of diseases

Plant strawberries, change or control the environmental conditions for their growth and development, overcome unfavorable factors, make them blossom and bear fruit normally, harvest ahead of time, and supply the market out of season. Greenhouse cultivation has the characteristics of low investment, quick effect, high yield and good benefit. The yield per mu is 1500 kg, which is more than twice that of the open field, and the output value is more than 10 times higher than that of the open field. In order to prolong the supply period of strawberries and meet the demand of annual supply, four cultivation forms are commonly used at present:

(1) promoting cultivation (maturing in late autumn and early winter from November to December).

(2) semi-facilitative cultivation (matured and listed from February to March).

(3) Super-facilitative cultivation.

(4) restraining cultivation.

Although the use of greenhouse production has many advantages, but also has shortcomings, because of the high temperature and humidity in the greenhouse. It is easy to create favorable environmental conditions for the occurrence of diseases and insect pests. It is particularly important to strengthen the comprehensive prevention and control of diseases and insect pests, and it has become the key link to realize the high and stable yield of strawberries in greenhouse.

1. Leaf spot

Also known as snake eye disease, mainly damage leaves, petioles, fruit stalks, tender stems and seeds. Small dark purple spots are formed on the leaves, which are enlarged to form near-round or oval disease spots, with purple-red-brown edges, gray-white center and slightly fine wheels, so that the whole disease spot is snake-eye-like, and small black grains are not formed on the disease spot.

Prevention and control measures: timely removal of diseased leaves, old leaves. The initial stage of the disease with 70% chlorothalonil wettable powder 500 ~ 700 times liquid, ten days later spray again. Or spray 75 kg of water with 70% mancozeb wettable powder, 200 grams per mu.

2. Powdery mildew

It is mainly harmful to leaves, but also to flowers, fruits, pedicels and petioles. The leaves are rolled up in the shape of a spoon. The flower buds and petals are purplish red, can not bloom or bloom completely, the fruit is not inflated, is slender, and the young fruit loses luster and hardens. Near-ripening strawberries will lose their commercial value when they are damaged.

Control measures: focus on spraying Baume 0.3 degree stone sulfur mixture in and around the disease center strain. After harvest, the leaves of the whole garden were cut and sprayed with 1000 times of thiophanate methyl or 5000 times of methamphetamine and 5000 times of Teflin.

3. Grey mold

It is the main disease after flowering, which can occur on flowers, petals, fruits and leaves. Brown spots were formed on the fruit during the expansion period, and gradually enlarged. Botrytis cinerea caused the fruit to soften and rot, which seriously affected the yield.

Control measures: spray with 25% carbendazim wettable powder 300 times solution, 50% carbendazim wettable powder 800 times solution, 50% prohydantoin 500 times ~ 700 times liquid and so on.

4. Root rot

Starting from the lower leaf, the leaf margin becomes reddish brown, gradually withered upward, and even withered to death. The pillar begins to turn dark brown and rotten in the middle, and the central column of the root is red.

Control countermeasures: before transplanting strawberries, use 40% asparagus green powder 600 times liquid, pour on the border, and then cover the soil, flatten and transplant, in order to effectively kill the bacteria in the soil, reduce the number of bacteria in the field, and reduce the chance of infection.

5. Verticillium wilt

The disease is a soil disease, and the main symptoms are deformities of young leaves, yellowing leaves and rough leaf surfaces. Then the leaf margin browned and withered inward until it died.

Control measures: strictly introduce the planting of disease-free plants, shorten the renewal life, disinfect the soil with 13.5 ~ 20 liters of chloropicrin or solar film irrigation, and remove those who have been burned.

Key points of cultivation techniques of virus-free strawberry varieties strawberry (scientific name: Fragaria × ananassa Duch.), perennial herb, 10-40 cm high. Stems below leaves or subequaling, densely opened. Show yellow pilose. Leaves Ternate, leaflets short-stalked, thick, Obovate or rhombic, dark green above, few glabrous, pale green below, sparsely hairy, densely along veins; petiole densely covered with yellow pilose. Cymes, leaflets with a short stalk below inflorescence; flowers bisexual; sepals ovate, slightly longer than epicalyx; petals white, suborbicular or Obovate-elliptic. Aggregate fruit large, persistent sepals erect, adherent to fruit; achene apex ovate, smooth. The florescence is from April to May and the fruiting period is from June to July.

Strawberry is a nutritious health fruit. Virus-free strawberry is a new variety with large fruit type and high yield introduced from abroad, which is accelerated by plant tissue culture and virus-free technology. In order to give full play to the power of improved varieties, in addition to conventional strawberry cultivation methods, combined with the characteristics of improved varieties, it is suggested to adopt the following technical measures: first, to select land with high fertility and conditions of drainage and irrigation, where strawberries have not been planted before, at the end of August and early September, organic fertilizer was applied per mu of ploughed land with 8000 kg of organic fertilizer, 200 jin of bean cake and 200 jin of phosphate fertilizer as base fertilizer. Strawberry is a fertilizer-tolerant and high-yield crop, which should ensure the nutrients needed for growth, development, flowering and fruiting. Strawberries produced with organic fertilizer are sweet and delicious. Strawberries made from chemical fertilizers taste sour. . Second, planting method and density. It is recommended to use double-row high ridge planting. The width of each ridge is 50cm, the row spacing is 30cm, the plant spacing is 25-30cm, and the density is 6000-7000 plants per mu. The planting depth of strawberry should be full root and shallow planting, and the soil can not cover the seedling center. Third, transplant at the right time. Make sure to send it early before winter. It is generally appropriate to transplant in October (slightly earlier in the north of the Yangtze River and slightly delayed in the south of the Yangtze River). Watering or watering in time after transplanting to promote its survival. After a week of survival, human dung and urine per mu or 50 jin of compound fertilizer was used to promote its rooting and early development, and topdressing 1-2 times (the best nitrogen, phosphorus and potassium compound fertilizer for fruit trees) to promote its rooting. "there were strong seedlings before the year, but great fruit after the year. Fourth, topdressing in time to promote flower bud differentiation. In the middle of November, 50 jin of human feces and urine or compound fertilizer and 40 jin of potash fertilizer were applied per mu to ensure the nutrients needed for flower bud differentiation. Fifth, apply sufficient fruit fertilizer. At the end of March of the second year, the plant grows vigorously, so it is necessary to apply sufficient fruit fertilizer in time to promote the development of flowers and fruits and promote large fruits. Apply compound fertilizer 50 jin per hole, not nitrogen fertilizer alone. Sixth, the fruit should be thinned in time and the stolon should be removed. Strawberries begin to blossom and bear fruit in early April, when a large number of buds and fruits can be formed. the fruits on weak fruits and small branches should be removed in time to ensure that each plant has 8-10 fruits, no more than 15 at most. At the same time, it is found that the stolon should be removed in time to reduce nutrient consumption and promote big fruit. Seventh, remove weeds in time after fruit harvest, root out diseased plants and weak plants, leaving only 1/4 new seedlings, and the excess seedlings can be transferred to other fields with soil. the general culture coefficient of breeding seedlings can reach 20-50 times. Virus-free seedlings should be eliminated after 2-3 years of propagation. new virus-free seedlings can be introduced from our room to replace them, otherwise the fruit will become smaller, deformed and the yield will decrease due to virus infection year by year. eight. If you want to bear fruit in winter, you can use greenhouse or vegetable greenhouse to promote cultivation, winter flower non-dormant varieties or Baojiao Zaosheng, Fengxiang, Mingbao, 94-3, Nvfeng, American No. 13 and other spring varieties covered with greenhouse when the temperature drops below 10 ℃ from November to December, and then set a small greenhouse to keep the temperature at about 10 ℃. January to May, that is, the results of five months, mature listing in batches. nine. If you want strawberries to mature one month earlier than the normal season, plastic film and shed film can be used to cover heat preservation, and strengthen fertilizer and water management. The results were listed from March to April. ten. Covering heat preservation in greenhouse or small shed and promoting cultivation, honeybees or artificial pollination should be released, which will help to increase the rate of big fruit and increase the yield. During the result period, 0.2% potassium dihydrogen phosphate or 2% superphosphate solution was sprayed with foliar topdressing, which could also increase production and income.
