Microorganism soil restoration conditioner as well as preparation method and application thereof

Abstract

The invention discloses a microorganism soil restoration conditioner as well as a preparation method thereof. The preparation method comprises the following steps: crushing 10 to 25 parts of plant carbon powder, filtering the crushed plant carbon powder by virtue of a 120-mesh screen to obtain plant carbon powder; mixing the plant carbon powder and 0.5 to 3.5 parts of pseudomonas aeruginosa underthe effect of 1 to 15 parts of a biological chelating agent, chelating and fermenting for 48 hours at 40 DEG C, then successively and uniformly mixing the fermented mixture and 20 to 35 parts of biological organic matter, 15 to 35 parts of bentonite, 10 to 40 parts of organic silicon, and 10 to 25 parts of weathered coal, and stirring to obtain the microorganism soil restoration conditioner; and placing the microorganism soil restoration conditioner in a thickened polyethylene plastic bag and introducing nitrogen to protect the storage of the conditioner. The microorganism soil restoration conditioner can restore and condition a soil micro environment, can activate the soil to promote crop roots to absorb the nutrition, thereby improving the quality of crops and increasing the yield; the effect of reducing the consumption of fertilizer is apparent, and the microorganism soil restoration conditioner is environmentally friendly and residue-free.

Description

technical field [0001] The invention relates to the technical field of soil remediation conditioner, in particular to a microbial soil remediation conditioner and its preparation method and application. Background technique [0002] Soil is the natural base for plant growth and reproduction, the basic means of production in agriculture, and an extremely important natural resource for human survival. With the intensification of industrial and urban pollution and the increase in the types and quantities of agricultural chemicals, soil heavy metal pollution is becoming more and more serious. Soil heavy metal pollution is concealed. Long-term use of chemical fertilizers and chemical pesticides will accumulate harmful heavy metals in the soil to a certain extent, which will not only lead to the decline of soil organic matter, soil compaction and degradation, and the decline of crop yield and quality, but also cause pollution through runoff and leaching. Surface water and groundw...

AI Technical Summary

Problems solved by technology

Phytoremediation technology is suitable for the treatment of most heavy metals. It has strong applicability and is suitable for the treatment of large-scale contaminated sites. However, this treatment has high requirements on soil conditions and is limited by environmental factors. The remediation depth is only in the rhizosphere and the remediation period is long. , and the heavy metal concentration will significantly inhibit the normal growth of plants
