Special organic-inorganic compound fertilizer for mulberries and preparation method thereof

Abstract

The invention discloses a special organic-inorganic compound fertilizer for mulberries. The special organic-inorganic compound fertilizer at least comprises an organic fertilizer, urea, monoammonium phosphate, potassium sulfate, ammonium bicarbonate, a medium trace element mixture and a complex microbial inoculant (consisting of saccharomycetes, bacillus cereus and bacillus megatherium). The preparation method comprises the following steps: weighing the urea, the monoammonium phosphate, the potassium sulfate, the ammonium bicarbonate and the medium trace element mixture, crushing, adding the organic fertilizer and the complex microbial inoculant, uniformly mixing, and carrying out drum granulation and coating to obtain the special organic-inorganic compound fertilizer for mulberries. The bacillus cereus and the micromonospora echinospora are added into the organic-inorganic compound fertilizer, metabolites generated during fermentation of the micromonospora echinospora have bacteriostatic activity, after fertilization, the bacillus cereus enters soil through release to generate antibacterial substances, metabolites generated by the micromonospora echinospora in the fermentation period has a doubled antibacterial function, so that the propagation of mulberry sclerotium is inhibited, the occurrence of the mulberry sclerotium disease is prevented, the nutritional ingredients in the soil are degraded, and the ecological environment is improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a special organic-inorganic compound fertilizer for mulberries and a preparation method thereof. Background technique [0002] Mulberry trees are susceptible to sclerotinia, which is commonly known as ginkgo disease. According to different pathogens and diseases, it is divided into three categories: mulberry hypertrophic sclerotinia, mulberry shrinking sclerotinia and mulberry small-grained sclerotinia . Although the pathogenic bacteria of different types of mulberry sclerotinia are different, the infection cycle is basically the same, and the disease spreads all over the country, causing great harm to the fruit mulberry industry. At present, mulberry sclerotinia is mainly controlled by chemical pesticides and agronomic measures. However, agronomic measures have little control effect. Excessive use of chemical pesticides not only makes pathogenic bacteria develop drug resistance, but...
