Facilities eggplant cultivation management misunderstanding
In winter, with the cultivation of eggplant with facilities, there are still some misunderstandings in the management process of vegetable farmers, which should be improved.
Misunderstanding 1: Many farmers in the new greenhouse do not grow seedlings. Many farmers believe that there are fewer root-knot nematodes in the new greenhouse, Verticillium wilt, blight, and bacterial wilt are less likely to be planted. it's not true. The planting of ungrafted eggplant seedlings in the new greenhouses caused the temperature to rise after the Spring Festival. The eggplant trees withered, died, and even became obsolete. The eggplant grafted with Santos rootstock was relatively normal and the yield was high. When grafted seedlings are planted, if they are grafted and colonized too early, they are prone to premature aging, and after the year, the yield is low, affecting income.
Myth two: Reapplying chemical fertilizers and ignoring organic fertilizers to re-apply chemical fertilizers can cause soil compaction, severe salinization on the ground, green moss on the surface, severe red moss, impeded root system development in high-concentration soil solutions, aging of leaves, and vegetative growth. Bad, the output declines. Such greenhouses should be supplemented with organic fertilizers, with or without chemical fertilizers to reduce fertilizer damage.
Misunderstanding 3: Single fertilization, partial application of nitrogen fertilizer Currently, fertilization of vegetable growers is dominated by nitrogen fertilizers. Phosphate fertilizers, potash fertilizers, and trace fertilizers are neglected, resulting in excessive nitrogen wastage and waste, and it is also easy to cause salty disorders in the soil and increase disease severity. In particular, the approximate ratio of nitrogen, phosphorus, and potassium required for eggplant is 3:1:4. Therefore, large-scale use of nitrogen fertilizer in the result period does not meet the growth pattern of eggplant. Should avoid the application of a single fertilizer, nitrogen, phosphorus, potassium fertilizer application.
Misunderstanding 4: Improper use of pesticides in mixed plants The prevention and treatment of eggplant diseases should be based on prevention and supplemented by treatment. Preventing the use of drugs in advance is not only cost-effective, but also effective. Some vegetable farmers, regardless of their chemical composition, like to use a variety of pesticides for compounding. Such use of drugs results in a chemical reaction between some agents, which reduces the efficacy of the drug. Second, when the concentration increases, the leaves are often immersed in high-concentration liquids. Reduced function, accelerated aging, reduced photosynthesis.
