Abstract

The invention belongs to the technical field of grassland degradation restoration, and discloses a method for repairing a grassland plaque sand land. The method comprises the following steps: acquiring grassland image data, and carrying out preprocessing and feature extraction to obtain the range of the grassland plaque sand land; determining node static technical information adapting to local regions and soil conditions; based on the range of the grassland plaque sand land and the node static technical information, carrying out ditching on the sand land boundary, and planting white poplar trees at the bottoms of ditches; covering the inner surface of the boundary of the plaque sand land with a plant fiber net in advance to construct a biological fence; turning over the grassland plaque sand land, and applying a soil remediation water-retaining agent; carrying out soil turning and ridging, breaking hardening of ridge surfaces, and flattening the ridge surfaces; sowing pasture seeds in the flattened sand land, and carrying out soil covering, watering and field management; and carrying out reseeding based on the grassland condition in the next year until the grassland recovers. The soil physical structure of the plaque sand land can be improved, the fertility of the plaque sand land is improved, the severe drought environment of the grassland is resisted, and the growth of pasture is promoted.

Description

Technical field [0001] The present invention belongs to the field of grassland degradation repair technology, in particular to a repair method of grassland plaque sand. Background technique [0002] At present, China's grassland area is about 400 million hectares, accounting for 40.7% of the land area, which is the largest land ecosystem and the most important green ecological barrier, and is also an important relying on the basic production of agricultural and animal husbandry. However, due to unreasonable grazing system, blind reclamation, abuse, etc. The main manifestation of grassland degradation is reduced by grassland vegetation coverage, changes in plant community, decreased species diversity, increased toxic weed, increased bare land, and decline in grassland productivity, etc., resulting in weakening of grassland ecosystems, such as soil erosion Weakened, soil nutrient water separation. In addition, grassland degradation will also affect climate change, leading to biomet...
