Compared with other vegetables, sweet pepper roots are underdeveloped, and the regeneration ability after root injury is weak. In particular, the current high temperature and high ground temperature are not conducive to the normal growth of sweet peppers. Therefore, management of top dressing should be more cautious. Only reasonable top dressing can effectively promote rooting, cultivate strong trees, and increase yield.
First, a small amount of fertilizer was used before the results to promote root growth. In general, before the results of sweet pepper should not be flushed with chemical fertilizers, otherwise it will easily lead to plant growth. However, in the summer, the early stage of colonization of bell pepper is easy to take root slowly due to high ground temperature, slow seedling slow, you need to topdressing (mainly functional fertilizers) to promote root seedlings. In general, large source new fast gunners or chitin can be used in conjunction with Fang Run (20-20-20) to flush and promote rooting. Dayuan new fast gunner Mu with 40-50 pounds, Fang Run 5-10 pounds.
Second, the results of the initial amount of fertilizer, promote tree attack. When the fruit is in the size of a walnut, it begins to top-dress. The top dressing time should not be too early nor too late. Prematurely due to adequate nutrition and water supply, the plants grow too vigorously to affect the development of flowers and fruits; too late can easily affect the growth of the plants. At this time dressing can be used Fang Run (20-10-30), 10-15 pounds per mu.
Once again, the result was a large amount of fertilization at the peak of the season. As the plant enters the full fruit period, the plant is dominated by reproductive growth. The purpose of the fertilization is mainly to ensure the normal expansion of the fruit and the normal differentiation of flower buds. A large number of plant results, the amount of fertilizer they need should be gradually increased, but taking into account the factors of high temperature in summer, should not be excessive overflooding, such as flushing Shi Fang Run can be applied 15 pounds each time, continuous rushing several times.
