Soil conditioner and preparation method thereof

Abstract

The invention discloses a soil conditioner and a preparation method thereof and relates to the field of soil conditioners. The soil conditioner is prepared from the following raw materials in parts byweight: 10 to 15 parts of straw particles, 40 to 45 parts of fermented cow dung, 3 to 7 parts of medical stone, 2 to 5 parts of dolomite powder, 5 to 10 parts of modified attapulgite, 2 to 5 parts ofdesulphurization gypsum powder, 4 to 9 parts of seafood shell powder, 5 to 10 parts of plant ash, 4 to 9 parts of sweet potato waste, 4 to 9 parts of fermented residue, 1 to 3 parts of shiitake mushroom extract, 1.5 to 3.5 parts of plant growth agent, 2 to 5 parts of amino acid salt, 1.5 to 3.5 parts of ferric chloride, 3 to 7 parts of ammonium dihydrogen phosphate, 2 to 5 parts of calcium superphosphate and 0.5 to 1.2 parts of microorganism acting bacteria. According to the soil conditioner, the soil fertility can be improved and a soil caking phenomenon is improved; the breathability, seepage, fertilizer-keeping and water retention capabilities of salt-alkali soil are remarkably enhanced; the physical-chemical properties of the soil are effectively improved.

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.
