Formula for improving soil

Abstract

The invention discloses a formula for improving soil. The formula comprises the following raw materials of, by weight, 32-36 parts of dry organic matters, 14-18 parts of humic acid, 12-16 parts of biomass carbon, 8-10 parts of slag micro-powder, 6-8 parts of medical stone powder, 2-4 parts of ammonium hydrogen carbonate, 4-8 parts of a heavy metal treatment agent, 4-6 parts of a soil aggregate promoter and 1-3 parts of an acid-base conditioner. The invention aims to provide a formula for improving soil, a soil modifying agent can provide the abundant organic matters, the soil aggregates, heavymetal in the soil is removed, the practical value is higher, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of improvers, in particular to a formula for improving soil. Background technique [0002] Soil improvers are mainly used to improve the physical, chemical and biological properties of soil to make them more suitable for plant growth, rather than materials that mainly provide plant nutrients. They are all called soil improvers. Soil is the basis of crop planting and is precious. Natural resources, but the current soil compaction, serious pesticide residues, rampant soil-borne diseases, soil water retention capacity decline, poor air permeability, and with the rapid development of industry and mining in today's society, soil heavy metal pollution is becoming more and more serious, and most of them are in the form of compounds in nature Existence, with the mining and processing of heavy metals by humans, many heavy metals such as lead, chromium, mercury, etc. have entered the atmosphere, water or soil, causing...

[0002] Soil improvers are mainly used to improve the physical, chemical and biological properties of soil to make them more suitable for plant growth, rather than materials that mainly provide plant nutrients. They are all called soil improvers. Soil is the basis of crop planting and is precious. Natural resources, but the current soil compaction, serious pesticide residues, rampant soil-borne diseases, soil water retention capacity decline, poor air permeability, and with the rapid development of industry and mining in today's society, soil heavy metal pollution is becoming more and more serious, and most of them are in the form of compounds in nature Existence, with the mining and processing of heavy metals by humans, many heavy metals such as lead, chromium, mercury, etc. have entered the atmosphere, water or soil, causing serious heavy metal pollution. Heavy metals themselves are difficult to degrade, and heavy metals entering the soil cannot be destroyed Microorganisms decompose and accumulate in the soil for a long time, and some are absorbed by crops and finally enter the human body through the food chain, which has certain ecological risks

[0003] Although existing soil improvers can provide rich organic matter, they are poor in removing heavy metals in the soil. Chinese patent document "(Application No.: CN201210277844.1)" discloses a soil improver and its preparation method, soil improver Including the following components by weight ratio: 6-12 parts of coal gangue, 8-16 parts of dry organic matter, the preparation method of soil conditioner, including mixing, ripening, drying, crushing and sieving; Chinese patent document "(application No.: 201410331400.0)" discloses a soil conditioner and its preparation method. The soil conditioner is composed of waste edible fungus sticks, wood vinegar and microbial agent raw materials. The quality of waste edible fungus sticks and wood vinegar is The ratio is 1 to 3:0.5 to 2.5, and the microbial agent accounts for 0.1% to 0.4% of the total mass of raw materials. The solution of the soil conditioner to the heavy metal content in the soil still needs further improvement
