Abstract

The invention provides a soil remediation agent for improving fertility of saline alkali soil. The soil remediation agent is prepared from the following raw materials in parts by weight: 40 to 60 parts of an organic remediation fertilizer, 10 to 20 parts of humic acid, 1.5 to 2.5 parts of a microbial agent, 25 to 30 parts of an organic fertilizer, 6 to 8 parts of weathered coal and 2 to 4 parts ofpyroligneous liquor. According to the saline-alkali soil remediation agent, the fertility of saline-alkali soil is improved, the alkalization degree of the saline-alkali soil is reduced, and the looseness and oxygen absorption capacity of the soil are improved; pond sludge, livestock and poultry manure and crop straw are utilized, so that the utilization rate of resources is increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil pollution remediation, in particular to a soil remediation agent and a preparation method for improving the fertility of saline-alkali soil. Background technique [0002] Soil is the natural environment on which human beings depend and an important resource for agricultural survival. The food, resource and environmental problems faced by the world are closely related to soil. However, with the continuous acceleration of industrialization, rural intensification and urbanization in our country, the area of ​​polluted soil is constantly expanding, and the problem of soil salinization is becoming more and more serious. Due to the salinization of the soil, the beneficial microorganisms in the soil are constantly being killed, resulting in poorer porosity and oxygen absorption capacity of the soil, becoming thinner and thinner, and even compaction, and the fertility of the soil is degraded. With the passa...
