Chemical formula of efficient soil improver

Abstract

The invention discloses a chemical formula of an efficient soil improver. The efficient soil improver is prepared from the following raw materials in parts by weight: 32-36 parts of straw, 14-18 partsof humic acid, 12-16 parts of biomass carbon, 8-10 parts of superfine slag powder, 6-8 parts of maifanite powder, 2-6 parts of ground phosphate rock, 2-4 parts of ammonium hydrogencarbonate, 4-8 parts of a heavy metal treatment agent, 4-6 parts of a soil aggregation promoter and 1-3 parts of a water retention agent. The invention aims at providing the chemical formula of the efficient soil improver. The soil improver can provide rich organic matters, enable the soil to aggregate and remove heavy metals in the soil, thus having higher practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of improvers, in particular to a chemical formula of a high-efficiency soil improver. 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 atmospher...

[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 conditioners can provide rich organic matter, they are poor in removing heavy metals from the soil. Chinese patent document "(Application No.: CN201210277844.1)" discloses a soil conditioner and its preparation method, soil conditioner Including the following components by weight ratio: 6-12 parts of coal gangue, 8-16 parts of straw, 0.2-3 parts of phosphate rock powder, the preparation method of the soil conditioner, including the steps of mixing, aging, 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 edible fungus waste sticks, wood vinegar and microbial bacterial agents. The edible fungus waste The mass ratio of stick and wood vinegar is 1~3:0.5~2.5, and the microbial bacterial agent accounts for 0.1%~0.4% of the total mass of raw materials. The solution of the soil conditioner to the soil heavy metal content still needs further improvement.
