Cherry tomato planting:

1, the soil temperature of10-15cm cultivated in the greenhouse is stable above 10℃, and the seedling age of cherry tomatoes in the greenhouse in winter is 70-80 days, that is to say, 70-80 days before the seedling planting is suitable. The best way to raise seedlings is direct seeding of single seed in a seedling bowl, and the soil for raising seedlings should be half of agricultural fertilizer and half of garden soil, and it is better to add 1% ammonium sulfate and potassium dihydrogen phosphate, sieve, mix well and compost for use after months. Sowing until the soil temperature is 25-30℃. The minimum temperature at night shall not be lower than 10℃, and watering at seedling stage should be done when wet, and it is not allowed to be watered frequently. In the seedling shed, the air is often released to exhaust the temperature and control the occurrence of diseases. Under normal circumstances, no topdressing is applied at seedling stage. When it is found that the seedlings are yellow and thin, 30g of urea and 30g of potassium dihydrogen phosphate can be sprayed on the leaves, and water 1 5kg, spraying1time for 4-6 days and 3-4 times can restore normal growth. To 7-8 leaves, can be planted when the bud is seen.

2. The suitable planting period is when the soil temperature is stable above 10℃. Apply decomposed agricultural fertilizer 15 cubic meter, urea 7-10 kg, calcium superphosphate 70-80 kg and potassium sulfate 40 kg per mu, spread it on the ground, then turn it over 30 cm twice, and fertilize the whole layer. Apply decomposed agricultural fertilizer 15 cubic meter, urea 7-1 10 kg, calcium superphosphate 70-80 kg, and potassium sulfate 40 kg. After spreading it on the ground, turn it over 30 cm twice to achieve full layer fertilization. Make a ridge with a width of 1 11.10 m and a height of 20-30 cm. The ridge top is planted in two rows, with a small row spacing of 40 cm. The plant spacing is 60-70 cm, and about 3 seedlings are planted per square meter. Water the soles of feet 3-4 days before planting, and it is forbidden to apply any furrow fertilizer and manure after planting. Cover with transparent plastic film after planting. It is better to cut the plastic film from the ridge top cover to both sides and cover it tightly at the seedling part.

3, management after planting to fruit-setting stage to control fertilizer and water, except for special drought, generally do not water or topdressing. The temperature is controlled at13-25℃. From the fruit swelling stage, the ground should always be kept warm, 50 grams of potassium dihydrogen phosphate should be applied to each ridge with water for each furrow irrigation, and 50 grams of urea1-2 times should be added when the seedlings are thin. Each seedling has 2-3 lateral vines under each panicle, forming 3-4 vines for pruning. The rest of the lateral vines should be removed only after the vines are thick, which is beneficial to the root growth. The vines should be kept without pinching the top, and the vines should be erected and tied in time: in winter greenhouse cultivation, anti-falling elements such as Zuoguoling, Tomato No.2, 2,4-D can be used to spray flowers to protect the fruits. When spraying, the back of the ear should be covered with paper shells to prevent the liquid medicine from falling on the seedlings and vines to inhibit growth. Harvest begins 60-70 days after planting. It can be harvested continuously for 4-6 months.

4, pest control pests are mainly leaf miner and whitefly. Liriomyza sativae can be prevented and controlled by Verdi spray. Whitefly can be controlled by mirex and smoke agent No.4. Diseases include gray mold, leaf mold and virus disease. Gray mold and leaf mold are mainly to strengthen the prevention of outdoor cooling and dampness elimination and to spray the control agents 1 and No.3, such as Sukeling, chlorphenamine, Wanmeiling and Garinon. Virus disease must be completely eliminated aphids and managers can't work while smoking and control the source of infection. Direct seeding of single seed in seedling bowl is an effective measure to control the occurrence of virus disease.
