Sand fixation control and planting integrated method for sand land

Abstract

The invention discloses a sand fixation control and planting integrated method for sand land. The method includes: spreading a sand-fixing agent to the surface of the sand land, planting plants on thesand land where the sand-fixing agent is spread to form a grid sand-fixing plant zone, and planting two rows of different crops in grids; planting shrubs or perennial herbs in the prevailing wind direction of one side of the sand-fixing plant zone. By adoption of the sand-fixing agent, sand loss is prevented; by planting of the crops in the grid windbreak sand-fixing plant zone, the vegetation coverage of the sand-fixing plant zone can be increased, effects of wind speed reduction and effective prevention of sand flowing are achieved, and accordingly crop damage caused by wind erosion or sandaccumulation can be prevented.

Description

technical field

[0001] The invention relates to the technical field of sand fixation in sandy land, and more specifically relates to an integrated method of sand fixation control and planting in sandy land. Background technique

[0002] At present, the degree of desertification in Northwest China is gradually aggravating, and at an annual rate of 3000km 2 Due to the large area of ​​land desertification, crop planting in the northwest sandy area is limited, and the crop yield is low, which seriously restricts the sustainable economic development of the northwest region.

[0003] At the present stage, most methods of controlling desertified land are based on planting sand-fixing plants, but sand-fixing plants only partially reduce the wind speed to achieve sand-fixing. When encountering strong winds, sand will still be lost under the action of wind. Due to the loose texture of the sandy soil and long-term drought and water shortage, the sand-fixing plants are restricted by wa...
