Problems solved by technology

[0003] The existing soil improvers used to improve the soil are mainly organic fertilizers and peat soils are directly applied as soil improvers. Although they can improve the fertility of the soil, they can only temporarily improve the fertility of the soil because they have no water retention function, but they cannot improve the soil. The nature of the soil, the solid-liquid-gas three-phase structure of soil retention, water retention, and ventilation is not ideal, which is not conducive to the growth of plant roots

Abstract

The invention relates to the technical field of soil improvement, in particular to an acidic soil improver which is composed of 150-180 g/kg of humic acid, 150-180 g/kg of calcium oxide, 0.22-0.36 billion/g of composite microorganism flora powder, 20-30 g/kg of chitosan powder, 50 ml/kg of angiosperm extract, 20-40 g/kg of oyster shell powder, 4.8-8.2 g/kg of mixture of calcium superphosphate and steel slag phosphorus fertilizer, 3.6-7.2 g/kg of magnesium sulfate and 2.8-4.8 g/kg of zinc sulfate. Compared with existing common soil improvers, the acidic soil improver has the advantages that content of alkaline ingredients and calcium needed for soil improvement is obviously high; almost no heavy metal ingredients are detected in the soil improver; after the soil improver is applied, soil bulk density after treatment is remarkably improved and lowered from 1.31 g/m3 to 0.95 g/m3.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an acidic soil improver. Background technique [0002] Due to natural factors and human factors, the quality of soil in my country is seriously degraded, especially soil acidification, which reduces the pH value of the soil and the reduction of basic cations. When the soil is toxic, the acidification of the soil reduces the internal pH of the soil, reduces the reduction of basic cations, and poisonous metal ions The increase of Mars caused the soil to be extremely viscous, the content of soil organic matter decreased, and the soil compacted. Therefore, it is necessary to apply soil amendments to urge the soil to improve; soil improvement is aimed at the poor geology and structure of the soil, and adopts corresponding physical, chemical and biological measures to improve soil shape, increase soil fertility, increase crop production, and improve the soil environment for hum...
