Eco-friendly modified-rice-straw soil modifier

Abstract

The invention discloses an eco-friendly modified-rice-straw soil modifier. The soil modifier is made from the following raw materials, by weight part, 6-7 of sodium alginate, 3-4 of calcium lignosulphonate, 1-2 of zinc lignosulphonate, 36-39 of fresh chicken manure, 5-6 of cocoa powder, 5-6 of calcium dihydrogen phosphate, 4-5 of potassium humate, 44-46 of rice straw, 1.7-1.8 of monochloro acetic acid, 13-14 of kaolin, 3-5 of calcium-based bentonite and a proper amount of water. Natural raw materials are adopted in the soil modifier and can be totally absorbed by soil during soil modification, and the problem of non-decomposable residues resulting from adoption of chemical organic materials in a conventional soil modifier is overcome. The soil modifier also has the functions of growth promotion, stress resistance and soil activation. Through the soil modifier, consumption of a fertilizer during a planting process in modified soil is reduced, and comprehensive development of recycling economy is achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an environment-friendly modified rice straw soil modifier. Background technique [0002] my country's agriculture is relatively developed, and it is a large agricultural country with a long history. A large amount of agricultural solid waste is produced every year, such as sugarcane dregs, rice husks, rice and wheat straw, etc. These agricultural solid wastes are often not comprehensively utilized in a timely manner, and are dumped and incinerated indiscriminately, causing huge pollution to the environment. The use of low-quality agricultural solid waste as raw material for soil improvement has become a research hotspot in the field of high-quality solid waste utilization and environmental restoration. Through simple physical or chemical treatment of these solid wastes, the adsorption performance of heavy metals and organic pollutants in the soil can be improved, the ph...
