Soil conditioner and preparation method thereof

Abstract

The invention relates to the field of soil improvement, and particularly discloses a soil conditioner and a preparation method thereof. The soil conditioner comprises, by weight, 50-60 parts of plant organic matters, 20-30 parts of excrement, 10-20 parts of mushroom dregs, 5-15 parts of a regulator, 8-15 parts of chitosan, 2-12 parts of hematite and 2-12 parts of aluminum oxide. The preparation method comprises the following steps: uniformly mixing the plant wastes, the excrement and the mushroom dregs, performing anaerobic fermentation, adding the conditioning agent, the chitosan, the hematite and the aluminum oxide after anaerobic fermentation, performing fermentation again, and cooling to 15-20 DEG C after fermentation to obtain the soil conditioner. After the soil conditioner is soaked in deionized water, the content of residual total nitrogen in soil reaches 0.96 g / kg or above, the content of total phosphorus reaches 0.53 g / kg or above, the content of organic matter reaches 52.68 g / kg or above, and the total cation exchange amount reaches 7.83 cmol / kg or above.

Description

technical field [0001] The application relates to the field of soil improvement, more specifically, it relates to a soil conditioner and a preparation method thereof. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. With the development of industry, harmful substances in industrial production continue to flow into the soil, and the unreasonable use of herbicides, pesticides, chemical fertilizers, etc., lead to soil pollution, which deteriorates the physical and chemical properties of soil in some areas. Nutrient loss, so that the plant cannot grow normally. [0003] At present, in order to improve the soil environment and make the soil more suitable for plant growth, people generally use fertilizers and soil improvers to adjust the soil environment. Soil conditioner refers to the material added to the soil...
