Due to the improper use of auxiliaries, tomato fruit, cracked fruit, and green top are often caused. It is recommended that the control of tomato should be based on nutritional regulation. 1 Small fruit disease households use tomato (Zhongfeng Wang) at tomato seedling stage with a large dose and late (in the case of tall plantlets). Although the plant height is controlled, it also inhibits the development of the ear. This stage should adopt the rooting seedling method, the specific method is: use 500-800 times GAO Mei organic humic acid active liquid fertilizer to root, 100-150g per plant, another spray Wanchunchun plant auxiliaries plus hymexiling or green enjoy On the 1st, the organic nutrients produced by the leaves are transferred to the root system, which promotes root development and improves disease resistance. 2 Dehiscences The use of a booster (or Dwarf King) for chemical control will make the tomato skin thicker and cause the pulp to expand rapidly to form dehiscence. At this stage, boron should be added to reduce the temperature of calcium, the specific method is: in the tomato flowering period of spraying humic acid 300-500 times boron calcium, or high US 300-500 times the liquid, with small fertilizer flushing Zhuang root potassium treasure, also Chong Shi Shi Gao Zhuang Chong Shi Shi Gao. 3 Some farmers in Qingding disease have increased their fertilizer and water management, and their fruits have developed too quickly. However, uneven spraying of hormones has caused uneven development of various parts of the fruit, leading to the development of blue-green disease. Root-cutting cooling method should be adopted at this stage. The specific method is: when the young fruit of the second and third ear of tomato, open ditch (or acupuncture) biological organic fertilizer plus potassium sulfate compound fertilizer, promote the growth of secondary roots, enhance the suction and absorption capacity , laying a good foundation for later growth. In addition, cooling is also the key to promoting the early listing of tomatoes.
