How to grow cherry tomatoes

There are actually many types of tomatoes, one of which is cherry tomatoes. Cherry tomatoes are also loved by many people and are very delicious. Here I will introduce to you how to grow cherry tomatoes.

1. Seedling cultivation

The soil temperature of 10-15 cm in greenhouse cultivation is stable above 10℃, which is the suitable period for planting. The best age for cherry tomatoes in winter greenhouse is 70-80 days, that is, 70-80 days before the suitable period for planting is the seeding period. The best method for raising seedlings is single seed direct seeding in the seedling bowl. The seedling soil should be half agricultural fertilizer and half garden soil, and add 1% ammonium sulfate and potassium dihydrogen phosphate, sieve, mix and pile for more than a month. The soil temperature from sowing to emergence is 25-30℃. The minimum temperature at night should not be lower than 10℃. Watering during the seedling stage should be seen when it is wet, and small water should not be frequently watered. The seedling shed is often ventilated to discharge temperature and control the occurrence of diseases. Under normal circumstances, no topdressing is done during the seedling stage. When the seedlings are found to be yellow, thin and lack of fertilizer, 30 grams of urea and potassium dihydrogen phosphate can be sprayed on the leaves, with 15 kg of water, once every 4-6 days, and normal growth can be restored after 3-4 times. It can be transplanted when it has 7-8 leaves and flower buds appear.

2. Planting

The soil temperature is stable above 10℃, which is the suitable period for planting. Apply 15 cubic meters of decomposed agricultural fertilizer per mu, 7-10 kg of urea, 70-80 kg of superphosphate, and 40 kg of potassium sulfate. Apply it to the ground and then turn it 30 cm deep twice to achieve full-layer fertilization. Apply 15 cubic meters of decomposed agricultural fertilizer, 7-10 kg of urea, 70-80 kg of superphosphate, and 40 kg of potassium sulfate. Apply it to the ground and then turn it 30 cm deep twice to achieve full-layer fertilization. Make ridges 1-1.10 meters wide and 20-30 cm high. Plant double rows on the top of the ridge, with a small row spacing of 40 cm. The spacing between plants is 60-70 cm, and about 3 seedlings are planted per square meter. Water the bottom 3-4 days before planting, and no ditch fertilizer or ridge fertilizer is allowed after planting. Cover with transparent mulch after planting. Cover the mulch from the top of the ridge to both sides, and cut the film to cover it tightly at the seedling part.

3. Management

Fertilizer and water should be controlled from planting to fruiting period. Except for special drought, no watering or topdressing is generally required. The temperature should be controlled at 13-25℃. From the fruit expansion period, the ground should be kept warm and moist. Each time the furrow is irrigated, 50 grams of potassium dihydrogen phosphate should be topdressed with water per ridge. When the seedlings are weak, 50 grams of urea should be added 1-2 times. There are 2-3 side vines under each flower spike of each seedling, and 3-4 vines are pruned. The remaining side vines should be removed after the vines are thick, so that the roots are nourished by the vines, which is conducive to the growth of the root system. The vines should be left without pinching the tops, and the vines should be tied up in time: In winter greenhouse cultivation, when the flowers are in full bloom, you can use fruit setting spirit, tomato No. 2, 2, 4-D and other anti-drop agents to spray flowers and protect fruits. When spraying, the back of the fruit spike should be covered with paper shells to prevent the liquid from falling on the vines and inhibiting growth. Harvesting begins 60-70 days after planting. It can be harvested continuously for 4-6 months.

4. Pest and disease control

The main pests are leaf miners and whiteflies. Leaf miners can be controlled with Wei Di spray. Whiteflies can be controlled with cypermethrin and smoke agent No. 4. Diseases include gray mold, leaf mold and viral diseases. Gray mold and leaf mold are mainly prevented by strengthening ventilation, cooling and dehumidification, spraying cyproconazole, cyproconazole, chloranil, carbendazim and smoke agents No. 1 and 3. Viral diseases must be completely eliminated. Aphids and management personnel cannot smoke while working to control the source of infection. Single seed direct seeding in the seedling bowl during seedling cultivation are effective measures to control the occurrence of viral diseases.
