Method for constructing and treating sand barrier of sandy land wind-proof sand-fixing grass belt

Abstract

The invention provides a method for constructing and treating sand barriers of sandy land wind-proof sand-fixing grass belt, which comprises the following steps of: arranging rhombic sand barriers ofthe grass belts in a flowing sandy land and a semi-flowing sandy land, and arranging strip-shaped sand barriers of the grass belts in a fixed sandy land; mixing and sowing grass seeds with a specificproportion on the rhombic grass belt sand barrier and the strip grass belt sand barrier, and planting shrub seedling of different types between the rhombic grass belt sand barrier and the strip grassbelt sand barrier, and between the rhombic grass belt sand barrier and the strip grass belt sand barrier; and applying granular organic fertilizer in the grass belt sand barrier and between the grassbelt sand barrier. The method for constructing and treating sand barrier of sandy land wind-proof sand-fixing grass belt can effectively solve the problems of long control period, poor stability, poorsand control effect and the like of the sand-fixing belt formed by the existing wind-proof sand-fixing greening construction technology.

Description

technical field [0001] The invention relates to the technical field of sand prevention and control, and more specifically, to a method for rapid establishment and control of sand barriers in windbreak and sand fixation grass belts in desertified land. Background technique [0002] Desertification is caused by unreasonable human activities acting on the fragile ecological environment. It is mainly manifested in the decline of land productivity, loss of land resource functions, and land degradation that presents a desertified landscape. As one of the countries with large desert area, wide distribution and serious desertification hazards in the world, the rate of desertification in my country is accelerating and showing a trend of expansion. Therefore, how to effectively prevent grassland desertification is an urgent problem to be solved. [0003] In recent years, windbreak and sand control generally adopts the method of building shelter belts, that is, planting some shrubs in...
