Control method of sand barrier establishment and planting in windbreak and sand fixation grass belt in sandy land

Abstract

The invention provides a method for building and planting grass belt sand barriers for windbreak and sand fixation in sandy land, comprising: setting diamond-shaped grass belt sand barriers in mobile sandy land and semi-fluid sandy land, and setting strip grass belt sand barriers in fixed sandy land; Grass belt sand barriers and strip grass belt sand barriers are mixed with a specific proportion of grass species, and planted between diamond grass belt sand barriers and strip grass belt sand barriers and at both ends of diamond grass belt sand barriers and strip grass belt sand barriers Seedlings of different types of shrub materials; apply granular organic fertilizers in the sand barriers of the grass belt and between the sand barriers of the grass belt. The invention can effectively solve the problems of long treatment cycle, poor stability, poor sand control effect and the like in the sand-fixation zone formed by the existing windbreak and sand-fixation greening and planting 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...
