Prevention and control fertilizer for resisting banana wilt and preparation method thereof

Abstract

The invention discloses a prevention and control fertilizer for resisting banana wilt and a preparation method thereof. The prevention and control fertilizer comprises 80 to 100 parts of an organic compost, 40 to 50 parts of urea, 30 to 45 parts of a phosphorus fertilizer, 40 to 50 parts of a potassium fertilizer, 10 to 20 parts of nitrohumic acid, 30 to 40 parts of silicon dioxide, 5 to 10 parts of a filling material and 10 to 20 parts of an antagonistic microbial agent. The preparation method comprises the following steps: uniformly mixing an organic fertilizer, and carrying out stacking and fermentation so as to obtain a fermented mixture; naturally cooling the fermented mixture to 25 to 30 DEG C, then adding the urea, the phosphorus fertilizer, the potassium fertilizer and the antagonistic microbial agent into the fermented mixture, and carrying out uniform mixing for refermentation; and crushing the silicon dioxide and the filling material until the particle sizes of the crushed silicon dioxide and filling material are 200 meshes or above, adding the crushed silicon dioxide and filling material powder into a ferment obtained in the step S2, carrying out uniform mixing under stirring, and carrying out granulation and drying in the air so as to obtain the prevention and control fertilizer for resisting the banana wilt. According to the invention, on the basis of reasonably controlling nitrogen and increasing potassium, absorption of bananas to a silicon element is increased; and by combination of the antagonistic microbial agent, the banana wilt is inhibited.

Description

technical field [0001] The invention relates to the technical field of banana disease prevention and control, in particular to a fertilizer for the prevention and control of banana fusarium wilt and a preparation method thereof. Background technique [0002] Banana wilt, also known as Panama disease and yellow leaf disease, is a devastating soil-borne disease caused by the infection of Fusarium oxysporum Cuban specialization type 4 physiological race and causes the necrosis of banana vascular bundles. With the development of banana planting industry in China and even in the world, according to reports, there were more than 200,000 hm2 of banana orchards in Guangdong and Hainan provinces in 2010 alone, and suffered heavy economic losses due to infection with Fusarium wilt. At present, the disease is widespread in the Pearl River Delta and western Guangdong The main banana production areas in Guangdong Province spread rapidly, and the rate of diseased plants in banana orchards...

Problems solved by technology

[0002] Banana wilt, also known as Panama disease and yellow leaf disease, is a devastating soil-borne disease caused by the infection of Fusarium oxysporum Cuban specialization type 4 physiological race and causes the necrosis of banana vascular bundles. With the development of banana planting industry in China and even in the world, according to reports, there were more than 200,000 hm2 of banana orchards in Guangdong and Hainan provinces in 2010 alone, and suffered heavy economic losses due to infection with Fusarium wilt. At present, the disease is widespread in the Pearl River Delta and western Guangdong The main banana production areas in Guangdong Province spread rapidly, and the rate of diseased plants in banana orchards is generally 10%-40%, and seriously exceeds 90% (Qi Peikun, 2000; Lin Lanwen et al., 2003; Liu Jingmei et al., 2004). Banana Fusarium wilt has already It seriously affects the normal development of banana industry in our province. Therefore, it is imminent to strengthen the research on the prevention and control of banana fusarium wilt. For this reason, we propose a kind of fertilizer for the prevention and control of banana fusarium wilt and its preparation method to solve the above problems
