Soil improver and preparation method thereof

Abstract

The invention discloses a soil improver and a preparation method thereof, and relates to the field of the soil improver. The soil improver is prepared from the following raw materials in parts by weight: 17 to 22 parts of bentonite, 9 to 15 parts of modified montmorillonite, 5 to 10 parts of silicon dioxide, 4 to 8 parts of cinerite, 5 to 10 parts of carbon bran, 21 to 26 parts of animal waste, 6to 12 parts of fermentation residue, 2 to 5 parts of stem of Herba Schizonepetae, 2 to 5 parts of ramulus uncariae cum uncis, 4 to 8 parts of powdered rock phosphate, 3 to 7 parts of silicon-potassiumfertilizer, 2 to 5 parts of desulfurization gypsum, 2 to 5 parts of potassium fulvate, 1 to 3 parts of microbial bacteria powder, 1 to 3 parts of a nutritional agent and 1.2 to 2.5 parts of organic acid. According to the soil improver disclosed by the invention, through a synergistic effect of components, the physical property of soil can be improved, nutrient absorption of crops can be promoted,the soil moisture content can be effectively increased, the soil structure can be improved, and the water and the fertility conserving ability of the soil can be enhanced.

Description

technical field [0001] The invention relates to the field of soil improvers, in particular to a soil improver and a preparation method thereof. Background technique [0002] Soil is an important component of the geographical environment, the material basis of agricultural production, and the basic resource for ecological environment construction, which is inseparable from human beings. However, due to people's unreasonable development and utilization of soil, soil erosion, desertification, desertification, salinization and soil pollution have caused land degradation and soil quality decline. 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. [0003] At present, soil improvement materials in my country mainly include minerals, natural materials, synthetic polymer materials, and beneficial microbial prepar...

AI Technical Summary

Problems solved by technology

[0003] At present, soil improvement materials in my country mainly include minerals, natural materials, synthetic polymer materials, and beneficial microbial preparations. Improvement and regulation of physical and chemical properties such as resistance and reunion ability, the comprehensive functionality is not strong, and the cost of raw materials is high, and the product price is also high

[0004] Chinese patent CN103242851A discloses a humic acid soil improver and a preparation method thereof, which consists of soil improver mother liquor, amino acid, citric acid, polyacrylamide, humic acid, urea, ammonium dihydrogen phosphate, and potassium chloride. The mass ratio is 50-65:3-10:0.3-1.5:2.3-2.9:3-10:5-6:5-7, which can effectively increase the organic matter and nutrient content of newly repaired farmland, loosen and compact the soil, and improve the quality of the land. Productivity, but the fertilizer has poor air permeability and short fertilizer action time

However, it lacks the improvement and regulation of soil air permeability, water retention and agglomeration ability, and its comprehensive performance is not strong.
