Summer Cherry Tomato Cultivation Techniques

1. Cultivation season: seedlings can be raised from mid-June to mid-July, planted in greenhouses from mid-July to mid-August, and harvesting begins in early October.

2. Seeding and nursery: the seedbed should be properly watered before sowing, and covered with 1 cm thick sieved soil after sowing. Generally, 3 to 5 grams of seed are used for seedbeds per square meter, and 6 to 8 square meters of seedbeds are planted per acre. The ground humidity of the seedbed before emergence should be controlled at 20 ℃ during the day and 12 ℃ ～ 15 ℃ at night. When the seedlings grow 2 true leaves, the seedlings are divided in the evening or cloudy, and the row spacing is about 10 cm × 10 cm. Irrigation water was applied after planting, and the temperature was controlled at 25 ° C to 28 ° C during the day and 15 ° C to 18 ° C at night. After slow seedling temperature control in the day 20 ℃ ~ 25 ℃, night 13 ℃ ~ 15 ℃. Due to the high temperature in summer, watering is often required. Seedlings are planted when they reach 8 leaves.

3. Planting: Select sandy loam soil with deep soil layer, fertile soil, good ventilation, convenient drainage, neutral or slightly acidic pH value for planting. Preparing the ground 7-10 days before planting, the single-stem pruned plant spacing is 25-30 cm, and the double-stem pruned plant spacing is 45-50 cm. When preparing the land, apply 80 to 100 kg of quicklime, 2,000 kg of rotten organic fertilizer, 80 kg of cake fertilizer, 30 kg of superphosphate and 40 kg of compound fertilizer per acre. Among them, the cake fertilizer and 60% of the organic compost were sprinkled into the soil before the next site preparation, and the rest was thoroughly mixed and applied to the planting hole.

4. Field management: * Pour large water after fruit setting and watering every 5 to 6 days during the result period. The soil is required to be dry and wet, and watering should be reduced during the harvest period to prevent fruit cracking. After slow seedlings and before flowering, 10-15 kg of quick-acting compound fertilizer is applied per acre. * After the ears are hung up, the fertilizer should be re-chased once, and then combined with the batch harvest of the fruit to supplement the fertilizer 2 to 3 times. Fertilizer for cherry tomatoes in the fruiting period should be applied with dung or special compound fertilizer, generally about 10 kg per mu. As a result, 0.3% potassium dihydrogen phosphate can be sprayed on the foliage.
