Biological fertilizer for preventing and controlling watermelon fusarium wilt

Abstract

The invention discloses a biological fertilizer for preventing and controlling watermelon fusarium wilt. The biological fertilizer is prepared from, by mass, 35-50 parts of fermented ground beetle dung, 35-45 parts of fermented soybean meal, 2-5 parts of silicon calcium potassium magnesium, 3-6 parts of humic acid, 2-5 parts of bone meal, 3-6 parts of composite amino acids, 1-2 parts of medium and trace elements and 1-2 parts of functional microbes. The biological fertilizer for preventing and controlling watermelon fusarium wilt is prepared through the following steps: mixing the fermented ground beetle dung and the soybean meal with the silicon calcium potassium magnesium, humic acid and the medium and trace elements, adding the bone meal, the composite amino acids and the functional microbes, mixing above materials, drying the obtained mixture, and crushing the dried mixture. All components in the above product mutually cooperate and have synergism, so the product can be easily absorbed by crops, the resistance of the crops to bacterial wilt is improved, the incidence of the bacterial wilt is reduced, the application amount of the chemical fertilizer is reduced, and the quality of cultivated land is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a biological fertilizer for preventing and curing watermelon wilt. Background technique [0002] In recent years, due to one-sided pursuit of high yield, farmers have invested a large amount of chemical fertilizers in the planted land, which has caused soil compaction and acidification, which has seriously affected agricultural production. With the improvement of people's living standards, the quality requirements of crops are getting higher and higher. Biological application can improve the quality of crops and fertilize soil fertility. [0003] Watermelon bacterial wilt is a serious soil-borne disease, especially in acidified soil, which brings great challenges to agricultural production. [0004] At present, although there are also researches on fertilizers for preventing and treating Fusarium wilt of watermelon in the prior art, the obtained fertilizers often...
