Abstract

The invention discloses a bioorganic fertilizer for adsorbing heavy metals and improving greenhouse soil. Raw materials of the bioorganic fertilizer comprise, by weight, 83-88 parts of a decomposed organic fertilizer, 8-12 parts of biochar, 1-2 parts of attapulgite, 2-3 parts of functional bacteria, and 0.5-1 part of methyl salicylate, wherein raw materials of the decomposed organic fertilizer comprise, by weight, 45-60 parts of straws, 30-45 parts of traditional Chinese medicinal residues, 1-5 parts of a urea fertilizer with the nitrogen content of 46wt%, 1-2 parts of a straw fermentation inoculant, 1-2 parts of penicillium oxalicum and 0.5-1 part of brown sugar. The content of organic matters in the bioorganic fertilizer is not lower than 30%, the quantity of effective live bacteria in the bioorganic fertilizer is not lower than 0.02 billions/g, and the bioorganic fertilizer can effectively enrich heavy metals in soil and reduces the content of the heavy metals; and functional bacteria and methyl salicylate can dually defense internally and externally, can effectively inhibit breeding and invasion of root-knot nematodes, also can improve the structure of soil, increases the permeability, improves the pH value, and reaches yield increase, quality improvement and environmental protection.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a bio-organic fertilizer which absorbs heavy metals to improve greenhouse soil and a preparation method thereof. Background technique [0002] Due to economic development and social progress, people's demand for vegetables is increasing. Vegetable greenhouses are of great significance to solve the problem of vegetable demand in our country. In the future, vegetable greenhouses need to be large-scale and industrialized with high input, high output and high efficiency. However, high investment will exacerbate the negative problems inherent in my country's vegetable greenhouses. The extensive use of chemical fertilizers leads to soil acidification, compaction, and increased solubility of elements such as Fe, Mn, and Al in vegetable greenhouses, and will easily aggravate the problems of diseases and insect pests in the soil, especially root-knot nematodes, which are the ...
