Soil remediation agent with pest killing efficacy and preparation method of soil remediation agent

Abstract

The invention discloses a soil remediation agent with pest killing efficacy. The soil remediation agent comprises the following raw materials in parts by weight: 40-80 parts of an organic fertilizer,10-15 parts of croton fruit powder, 10-20 parts of durian shell powder, 8-15 parts of black soybean powder, 8-15 parts of tobacco stem powder, 10-20 parts of garlic stalks, 10-15 parts of honeycombs,6-8 parts of big-leaf tea (camellia sinensis), 4-8 parts of blastus caualeriei leaves, 3-7 parts of hemp seeds, 1-3 parts of zineb, 2-5 parts of baeckea frutescens, 2-5 parts of nano aluminium oxide,1-3 parts of horseradish, 20-50 parts of sugar cane juice, 2-5 parts of a selenium-enriched protein, 2-5 parts of polyrhachis dives, and 50-100 parts of water. The soil remediation agent provided by the invention can effectively remove heavy metals such as nickel in soil, realize soil remediation, and has a remarkable pest killing effect; the raw materials are easy to obtain and environmentally friendly, and secondary pollution to the soil is not easy to cause; and the preparation process is simple, the production costs are greatly reduced, and the soil remediation agent is beneficial for promotion and application of agriculture.

Description

technical field [0001] The invention relates to the technical field of soil pollution control, in particular to a soil remediation agent with insecticidal effect and a preparation method thereof. Background technique [0002] Soil remediation improver is a new type of biological strain in the form of powder, which has the characteristics of rapid reproduction, strong vitality, safety, non-toxicity, high temperature resistance, no inactivation during granulation and drying, and long-term preservation; it contains rich and high The value of active bacteria has the effect of improving soil structure. Composed of a variety of probiotics, it can greatly increase the beneficial bacteria in the soil and restore the diversity of soil microbial communities, enhance air permeability, effectively solve the problem of soil compaction, and improve the soil micro-ecological environment. However, due to the use of various chemical components, the existing soil remediation agents generally...

AI Technical Summary

Problems solved by technology

However, due to the use of multiple chemical components, the existing soil remediation agents generally have greater toxicity and are likely to cause secondary pollution to the soil; moreover, their cost of raw materials is high and their economic efficiency is relatively poor; meanwhile, their insecticidal efficacy is relatively poor.
