Straw composite antimicrobial soil conditioner and preparation method thereof

Abstract

The invention relates to a straw composite antimicrobial soil conditioner which is prepared from the following raw materials in parts by weight: 30-40 parts of straw juice, 20-30 parts of biochar, 20-25 parts of polyacrylamide, 10-15 parts of animal manure, 2-3 parts of turfy soil, 2-2.5 parts of plant ash, 2-3 parts of zeolite powder, 2-3 parts of microbial functional microbial inoculant, 2-3 parts of chitosan, 2-3 parts of mugwort extract, 2-3 parts of sodium benzoate, 2-3 parts of amino acid, 1-2 parts of starch and 1-2 parts of molasses powder. The plant wastes are used as the raw materials, thereby being beneficial to enhancing the soil quality, lowering the production cost and further improving the physicochemical properties of the soil. The soil structure is comprehensively improved, so that the soil is loose and air-permeable and has the effects of water retention and fertilizer retention, thereby enhancing the utilization ratio of the chemical fertilizer. The straw composite antimicrobial soil conditioner has the effects of killing bacteria, eliminating weed, promoting the development of the crop root system, enhancing the crop yield and improving the product quality.

Description

technical field [0001] The present invention relates to a kind of soil improver, more specifically, the present invention relates to a kind of straw composite antibacterial soil improver and its preparation method Background technique [0002] In order to increase the yield, people will apply a large amount of fertilizer when planting, and fertilization every year will inevitably lead to poorer soil quality, problems such as hardening, poor air permeability, and serious lack of nutrition, and the planting yield is getting lower and lower. The quality is also getting worse. And with the improvement of people's living standards, people began to pay attention to green food. How to effectively improve poor-quality soil and make full use of limited land resources is a major problem that needs to be solved urgently in agricultural production, ecological construction and environmental protection. Applying soil amendments is one of the important measures to restore degraded soil. S...
