Simple soil remediation method liable to implement

Abstract

The invention discloses a simple soil remediation method liable to implement. The method comprises the following steps: (1) polluted soil is deeply ploughed; the deep ploughing depth is 30-40 cm; then, wide and narrow rows are set; the wide rows are 2.5-3 m wide; the narrow rows are 1-1.5 m wide; and the row distances are 1.5-2 m; (2) grass and plant vines are paved on the surfaces of the wide and narrow rows; and a layer of farmyard manure is covered thereon; (3) microbial agents are fed in the soil; (4) plants are planted in the wide and narrow rows; and the planting distances are kept in 1-1.5 m during planting; (5) earthworms are fed in the soil; and (6) the earthworms are collected after feeding by 30-40 days. The microbial agents are fed in the soil, so that the content of microorganisms in the soil is increased, the decomposing effect of the microorganisms on pollutants is further improved, and the repair effect is improved; in addition, the soil repair effect is achieved through the excessive accumulation of the plants to heavy metal elements and the enriching effect of the earthworms on the heavy metal elements; and the whole repair process is simple and liable to implement.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, and in particular relates to a simple and easy-to-implement soil restoration method. Background technique [0002] When the soil contains too many harmful substances and exceeds the self-purification capacity of the soil, the composition, structure and function of the soil will change. Although there are many soil restoration methods on the market, they are all complicated and inconvenient to implement.
