The average yield per mu of cultivated cherry tomatoes was 4653.2 kilograms, which was 816.9 kilograms more than that of conventional cultivation, an increase of more than 20%, and the harvest period could be extended by more than 30 days. The main reason for increasing production is that the cultivation method keeps the cherry tomatoes in the middle and upper part of the greenhouse, and promotes new roots through soil pressure, shortens the nutrient delivery distance, and helps the fruits to absorb nutrients. First, choose a variety of high-quality, high-yield, disease-resistant Virgo, gold beads, purple jade, yellow pear, Zhu Li and other varieties, including the saint, Zhu Li is red, gold beads, Huang Yang pear yellow, purple purple . The individual fruit weights ranged from 12.8 to 15.2 grams, with 18 to 22 panicles per panicle. The virgins and purple jade are oval-shaped fruit, gold beads are round, yellow-orange pears are pear-shaped, and Julie is long cylindrical. Second, nurturing strong seedlings using plug electric heating root protection seedlings. The best formula for nursery substrate is mulberry stalks: straw: chicken manure is 3:3:4. The matrix was crushed, sifted, mixed and composted for 30 days and then inserted into a plug tray, and a hot wire was laid under the plug. Use small sheds and middle sheds to increase sheds and grasshoppers to keep warm. During the seedling period, the temperature is maintained at 25~30°C during the daytime. At night, the temperature needs to be heated by the electric heating line to keep the seedbed temperature above 10°C. Watering seedlings see dry see wet, can not be poured water. Third, colonization in the middle and late February, that is 7 to 8 leaves of seedlings, when the bud is planted. 7 to 10 days before planting, covered with film insulation, Mushi decomposed chicken manure 2000 kilograms, urea 10 kilograms, superphosphate 80 kilograms, potassium sulphate 40 kilograms, spread 30 centimeters deep after spreading, It is 90 cm wide, 20 cm high, and 30 cm wide. Each row is 2 rows and the spacing is 50 cm. Four, hanging vines, vines, cherry tomatoes using single vine pruning, when the plant grows to 30 cm high, hanging with a plastic rope. When the lower part of the 2 to 3 panicles were harvested, the lower disease, old and yellow leaves were removed, and the old vines were promptly dropped. The old vines were buried in the soil to promote new roots and promote plant growth. Fifth, fertilizer and water management After planting to control fruit and fertilizer to control the temperature, the temperature is maintained at 13 ~ 25 °C. From the beginning of fruit enlargement period, the ground should be kept moist. Generally, the roots of the plants should be placed under the membrane and piped with water. Each time, 200 g of potassium dihydrogen phosphate and 200 g of urea should be topdressed with water. 6. In early spring, the greenhouses can be cultivated in the flowering period. They can be used for flowering and fruiting, 2,4-D liquids and other anti-dropping agents to spray flowers and fruits, and the paperboard can be used to block the rear of the ear to prevent the liquid from falling onto the pods. Grow. 60 to 70 days after planting began harvesting. VII. Pest Control Pests mainly include leafminers and whitefly. The leaf miner was controlled with 20% of toxic chlorine 600 times, whitefly was treated with 10% imidacloprid 1000 times and 1% avermectin 600 times. Diseases mainly include gray mold, leaf mold, and viral diseases. Botrytis cinerea and leaf mold can be prevented and sprayed with 800 times liquid quickening and cooling on the basis of prevention of exhalation and temperature dehumidification. Virus disease can be controlled by spraying A600 liquid on the basis of eliminating aphids. (Jiangsu Suyu District Suyu Agricultural Technology Center (226100) Zheng Zhijun)
