Soil conditioner and preparing method thereof

Abstract

The invention discloses a soil conditioner and a preparing method thereof, and relates to the technical field of agricultural production. The soil conditioner is prepared from, by weight, 15-20 partsof modified apple branch biochar powder, 5-10 parts of pulverized fuel ash, 10-15 parts of alkaline residues, 25-35 parts of distiller's grains, 20-30 parts of medical stone, 15-35 parts of waste bacterial sticks, 10-15 parts of zeolite, 40-60 parts of calcium magnesium phosphate fertilizer, 5-10 parts of diammonium hydrogen phosphate and an appropriate amount of polyacrylamide spraying liquid, wherein the modified apple branch biochar powder is prepared by wetting apple branch biochar powder with a 6-10% dilute sulphuric acid solution, soaking the apple branch biochar powder with deionized water, conducting filtering 2-3 times, and then conducting vacuum drying modification. The apple branch biochar powder is prepared by conducting carbonization and deionized water treatment on apple branches, drying and smashing the apple branches, and then making the apple branches pass through a 100-mesh sieve. The calcium magnesium phosphate fertilizer contains by weight, 12-20% of P2O5. Accordingto the soil conditioner and the preparing method thereof, through the addition of the modified apple branch biochar powder, the capability of soil of exchanging positive ions can be effectively improved; meanwhile, by applying biomass carbon, the content of soil organic carbon can be effectively increased, soil agglomeration is promoted, and the soil circulation is coordinated.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a soil conditioner and a preparation method thereof. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. In our country, land resources are not only very limited, but also have a considerable proportion of soil with obstacles due to soil-forming factors or human factors, including erosion. , Poor texture, poor structure or cultivability, salinity, acidification, toxic substance pollution, unfavorable soil layer in the soil that hinders the growth of plant roots, excessive or insufficient soil moisture, low fertility or imbalance of nutrient elements, etc. [0003] Under normal circumstances, these barrier soils are difficult to use, but in recent years, the use of soil conditioners for improvement has shown better results. Soil conditioners are derived from agricultural pr...
