Abstract

The invention relates to a modified rice-straw soil amendment. The modified rice-straw soil amendment is prepared from the following raw materials in parts by weight:30-35 parts of rice straws, 20-30 parts of biochar, 10-15 parts of bean meal, 5-10 parts of cassava residue, 10-15 parts of chicken manure, 5-10 parts of diatom ooze, 2-2.5 parts of plant ash, 2-3 parts of zeolite powder, 2-3 parts of microbial functional bacterium agent, 2-3 parts of sodium benzoate, 1-2 parts of amino acid, 1-2 parts of starch and 1-2 parts of molasses powder. According to the modified rice-straw soil amendment, plant wastes are adopted as the raw materials, so that the improvement on quality of soil is facilitated, the production cost can be reduced; the physicochemical properties of the soil are improved, the structure of the soil is comprehensively improved, and the texture of the soil can achieve soft, air-permeable, water-retention and fertilizer retention effects; and the modified rice-straw soil amendment plays roles in increasing the utilization ratio of chemical fertilizers, promoting the root system development of crops, increasing crop yield and improving product quality.

Description

technical field [0001] The invention relates to a soil modifier, more specifically, the invention relates to a modified rice straw soil modifier and a preparation method thereof. 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. Soil amendments can effectively impr...
