Abstract

The invention discloses a soil restoration conditioner for controlling cadmium pollution. The soil restoration conditioner comprises 40-50 parts of lime, 45-60 parts of peat and 3-8 parts of zinc sulfate. It is prepared by drying, crushing, sieving, stirring and mixing lime, zinc sulfate and peat according to the weight ratio. The soil remediation conditioner of the present invention can simultaneously have the characteristics of increasing soil pH, reducing active Cd effective state, preventing soil chemical and physical properties from deteriorating, and increasing soil organic matter. Combine the adjustment of soil acidity barriers, the restoration of soil heavy metal pollution and the improvement of soil fertility to avoid the problems of poor governance efficiency, soil compaction, salinization, loss of organic matter and N, P, K elements, and nutrient imbalance caused by a single component. To achieve comprehensive treatment of cadmium-contaminated acidic soil, the purpose of coexistence of restoration and fertilizer use.

Description

technical field [0001] The invention relates to the field of agricultural production fertilizers, in particular to a soil repair conditioner for controlling cadmium pollution and acidic fields. Background technique [0002] Cultivated land is the foundation of agricultural production and an important resource for the survival and development of the people. The soil area polluted by heavy metals in my country has reached 300 million mu, accounting for 1 / 6 of the total cultivated land area, which shows that the overall situation of soil pollution in my country is very serious. The polluted fields in South China are mainly polluted by acidic soil and Cd. Insufficient quantity and low quality of cultivated land are the biggest obstacles restricting my country's agricultural production, and improving the quality of cultivated land is the fundamental way to develop agriculture in our country. It is an important task before us to make good use of land, maintain good land, maintai...
