Tomato fruitful period should mainly pay attention to water and fertilizer management, temperature control, plant adjustments and other work.
As a result, a large amount of water and fertilizer is required during the peak period. In the sunny morning, small water and large water are combined and poured. Once every 7 days, three water and two fertilizers are used. Topdressing uses small water, and empty water uses large water. Fertilizer has two parts, one is chemical fertilizer, which uses high-nitrogen and low-phosphorus potassium fertilizer. It uses 16-20 kilograms of vegetables and 1 mus of fertilization. One is biological bacterial fertilizer and 1 mu of prebiotic bacteria fertilizer is applied. - 20 kg. During the harvesting period, potassium fertilizer should be added. Potassium dihydrogen phosphate 2 kg per mu can be flushed to promote the rapid expansion of fruit in the later period. Pay attention to calcium, foliar spraying of Ribec calcium, 30 grams per mu, once every 10 days, can control the umbilical rot and cracking fruit. Tomato fruits appear blue or unevenly colored with 200 g/mu of Boron-Zinc. During this period, no foliar fertilizer with high nitrogen content or high hormone content can be sprayed to avoid uneven coloration and slow coloration of fruit.
This period adopts medium and high temperature management. The control temperature is 26°C-28°C during the day and 12°C at night. Properly high temperature in the shed can supplement ground temperature, promote better growth of tomato roots, and lay the foundation for the strong foal.
Falling vines are best chosen for sunny afternoons, where the height of vines is 30-40 centimeters, so that the tomato growth point is maintained at about 1.5 meters high. At the same time pay attention to promptly knock out the old leaves and the leaves that are folded too close to each other to ensure ventilation and light transmission, so that the two leaves of the two leaves of the tomato can be left intact.
