Composite biological soil modifier and application thereof

Abstract

The invention discloses an unpolluted, green and high-efficiency composite biological soil modifier which comprises the following components: trichoderma pseudokoningii fermentation liquor, bacillus subtilis fermentation liquor, water-soluble chitin, potassium humate and decomposed organic matter. The trichoderma pseudokoningii and the bacillus subtilis are high-efficiency bacterial strains which are obtained through screening and mutating, the trichoderma pseudokoningii fermentation liquor and the bacillus subtilis fermentation liquor are obtained by a liquor submerged fermentation technology, and the unpolluted, green and high-efficiency composite biological soil modifier can be prepared in a combination way. The soil modifier has the following functions that the physicochemical property of the soil can be improved, the hardening of the soil can be broken up, the volume weight of the soil can be reduced, the air permeability of the soil can be improved, the microbiological activity of the soil can be promoted, the growth of the plant root system can be promoted, the disease resistance of the crop can be enhanced, the yield of the crop can be improved, the quality of the crop can be improved, the original ecology of the crop can be recovered and the like, and the soil modifier is the novel soil modifier which is high-efficiency, environment-friendly and convenient to use.

Description

technical field

[0001] The present invention is a composite soil improver. Specifically, active composite bacteria are added as the center and potassium fulvic acid and decomposed organic matter are added, which can not only improve soil physical and chemical properties, but also provide nutrients necessary for the growth of crops. It is a green and efficient soil conditioner that inhibits plant diseases. Background technique

[0002] Soil is an important carrier of plant growth environment. It provides photosynthetic raw materials and attachment substrates for plants. Soil quality is closely related to crop yield. Soil quality refers to the ability of soil to sustain animal and plant production, maintain and improve water and air quality, and human health and life within the boundaries of natural or artificially managed ecosystems. The basis of soil quality is soil fertility, which is the ability of soil to provide and coordinate nutritional and environmental conditions fo...
