Biology soil preparing method for soil animal ecological restoration in abandoned farmland

Abstract

The invention discloses a biology soil preparing method for soil animal ecological restoration in an abandoned farmland and relates to a soil preparing method for abandoned farmland ecological restoration. The technical problems that currently, restoration and improving attention on soil animals from animal soil is low, soil animal restoration is purely by nature, restoration speed is low, and community composition is not complete are solved. The method comprises the steps that first, a biology soil base is prepared; second, the biology soil base is cultured in a pre-restoration target natural ecosystem; and third, the biology soil is transplanted to the abandoned farmland. The method has the advantages that the biology soil is cultured in the natural ecosystem, soil animals in the biology soil are attracted and amplified, then transplanting to the abandoned farmland is carried out, the fact that the soil animals are native species is guaranteed, invasion of alien species is avoided, ecological risks are avoided, soil animal restoration in the abandoned farmland can be promoted effectively, the effects of soil improving, soil organic matter increasing, soil porosity enlarging and water retention and weight gaining are achieved, and operation is easy.

technical field

[0001] The invention relates to a soil preparation method for ecological restoration of returned farmland. technical background

[0002] With the further strengthening of my country's ecological civilization construction and the improvement of ecological protection awareness, a large number of illegally reclaimed cultivated land and low- and medium-yield fields in major ecological function areas have already started or will soon start returning farmland to forests, returning farmland to grass, and returning farmland to wetlands. At present, the restoration of vegetation on returned farmland adopts natural restoration of seed banks, artificial planting or auxiliary restoration of transplanting, etc., which can be effectively restored in a short period of time. Compared with vegetation restoration, soil restoration is slower. The physical, chemical and biological properties of cultivated land soil have changed significantly compared with the soil properties of...
