Embodiment Construction

[0023] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details.

[0024] Aiming at the above-mentioned problems such as the long treatment period, poor stability and poor sand control effect of the existing sand-fixing greening construction technology for windbreak and sand-fixation, the present invention proposes a new sand barrier construction for windbreak and sand-fixation grass belt in sandy land. Planting control method, by setting different grass-belt sand barriers in mobile sandy land, semi-fluid sandy land, and fixed sandy land, the grass-belt sand barriers use annual and perennial fixed grass species to form a network structure in time and space order, Combined with suitable shrubs in sandy land, a stable sand barrier with shrub-grass belt structure can be...

Abstract

The invention provides a method for establishing and planting a wind-proof sand-fixing grass belt sand barrier in sandy land. The method includes: setting a rhomboid grass belt sand barrier in mobilesandy land and semi-mobile sandy land, and setting a strip grass belt sand barrier in fixed sandy land; subjecting a specific proportion of grass species on the rhomboid grass belt sand barrier and the strip grass belt sand barrier to mixed sowing, and planting different kinds of shrub seedlings between the rhomboid grass belt sand barrier and the strip grass belt sand barrier as well as both endsof the rhomboid grass belt sand barrier and the strip grass belt sand barrier; applying granular organic fertilizer in the grass belt barriers and between the same. With the method, problems of longtreatment cycle, poor stability and poor effect of sand control formed by existing wind-proof sand-fixing greening and planting technology and the like can be effectively solved.

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...
