Problems solved by technology

[0005] The present invention aims to solve the technical problems that the restoration and improvement of soil animals in biological soils are rarely concerned at present, and soil animals rely solely on natural recovery, the recovery speed is slow, and the community composition is incomplete, and provides a soil animal ecology that is applied to degraded land. Restorative biological soil preparation method

specific Embodiment approach 1

[0017] Specific implementation mode 1: This implementation mode is a biological soil preparation method applied to the restoration of soil animal ecology in returned farmland, specifically carried out according to the following steps:

[0018] 1. Production of biological soil base: 10 to 30 parts by weight of crop straw, 30 to 35 parts of soft rotted wood with epiphytic fungi, 30 to 55 parts of peat and 5 parts of returned farmland soil Fully mixed to obtain a biological soil base; the 10-30 parts of crop stalks, 30-35 parts of soft rotten wood of epiphytic fungi, 30-55 parts of peat and 5 parts of returned farmland soil were all obtained from the field direct access;

[0019] 2. Cultivation of biological soil base in the pre-restoration target natural ecosystem: divide the biological soil base obtained in step 1 into 20cm-40cm in thickness and 2m in area 2 ~5m 2 Rectangular bio-soil base, the rectangular bio-soil base is evenly scattered and piled up in the natural ecosyste...

specific Embodiment approach 2

[0027] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, 20 parts by weight of crop stalks, 35 parts of soft rotten wood of epiphytic fungi, 40 parts of peat and 5 parts of degraded The cultivated land soil was fully mixed to obtain a biological soil base; the 20 parts of crop stalks, 35 parts of soft rotted wood with epiphytic fungi, 40 parts of peat and 5 parts of returned farmland soil were all directly obtained from the field. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0028] Specific embodiment three: this embodiment is different from one of specific embodiments one to two: the soft rotten wood of the epiphytic fungus described in step one is soft rot white birch, black birch, Yue birch, Mongolian oak, poplar or mountain Poplar. Others are the same as one of the specific embodiments 1 to 2.

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.

Description

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...
