Similarly, we should pay attention to the application of organic fertilizer.

When the personnel of the Agricultural Service Center of Daibu Town, Liyang City, went to Niuchang Village to investigate vegetable cultivation, a farmer responded that the chili peppers he planted this year had seldom blossomed, and young peppers were easy to fall off. This year's varieties, fertilizers, and planting time were the same as last year, and last year's chili peppers were very productive. This is indeed the case when we go to the field and see it. He was asked to recall the planting process carefully, but he still said it was the same as last year. Judging from the growth of hot pepper, it is preliminarily judged to be the cause of excessive nitrogen fertilizer. In order to verify this judgment, the Agricultural Service Center tested the content of soil available nitrogen, phosphorus and potassium, and the results showed that available nitrogen was very high, phosphorus and potassium was low, which did not meet the needs of pepper flowering and fruiting. Why did this happen? The farmer said that last year, the base fertilizer of pepper was a sufficient amount of mixed fertilizer of stable manure and rapeseed cake fermented by retting heap, and this year's base fertilizer was also mixed fertilizer of barnyard manure and rapeseed cake, but it was not fermented and was directly applied. The problem lies here: the content of nitrogen in organic fertilizer is generally higher than that of scale potassium, the nitrogen of rapeseed cake is several times higher than that of phosphorus and potassium, and the ammoniation time of nitrogen-containing substances in unfermented organic fertilizer is longer, which is more than 2 months. During flower bud differentiation, flowering and fruiting, nitrogen in organic fertilizer is continuously supplied to pepper, which leads to high nitrogen in pepper plant and affects flowering and fruiting. It can be seen from this example that due to the short time from planting to flowering, the organic fertilizer in the base fertilizer must be applied after fermentation to ensure that nitrogen fertilizer is sufficient to promote the growth of branches and leaves in the early stage, and less nitrogen fertilizer to promote flowering and fruiting in the middle and later stage.
