Alpine region quicksand treating method with ligularia virgaurea plant

Abstract

The invention discloses an alpine region quicksand treating method with the ligularia virgaurea plant. The treating method comprises the steps that 1 moving sand dunes are settled, and the moving sand dunes formed by grassland desertification formed by over grazing in the alpine grassland are settled; 2 transplanting the ligularia virgaurea seedlings or sowing seeds of the ligularia virgaurea, the ligularia virgaureas on the deteriorated grassland are excavated with shovels before the rainy season, the ligularia virgaureas are transplanted to the moving sand dunes with manpower, and the seeds of the ligularia virgaurea on the deteriorated grassland are collected and sowed; 3 the transplanted ligularia virgaurea seedlings or the sowed seeds of the ligularia virgaurea are covered with covering objects. The alpine region quicksand treating method with the ligularia virgaurea plant has the advantages that the local materials are used, the operation is simple and convenient, the moving sand dunes are fixed with inedible poisonous grass of the livestock, not only can the biodiversity of the grassland be guaranteed, but also vegetation restoration of the moving sand dunes is guaranteed and the vegetation is free from the tread of the livestock, and grassland vegetation fast revegetation and environment improving in Alpine region grassland vegetation are achieved.

Description

technical field [0001] The patent of the present invention belongs to the technical field of sand prevention and control, and specifically relates to a method for controlling quicksand in alpine regions by using Ligia syringae plants. Background technique [0002] In recent years, under the superimposed influence of various factors such as global climate change, overgrazing, rat infestation, and human disturbance, land desertification in alpine regions has developed from sporadic distribution to local contiguous contiguous areas, presenting a trend of rapid expansion, which has affected regional ecological functions. Significantly affected. Although the mobile sand dune management technology is very mature in the arid area, it is difficult to apply it directly due to the special environmental conditions in the alpine area. Mechanical sand barriers can completely fix the mobile sand dunes in a short period of time, and if no biological measures are taken, the sand dunes may ...
