Abstract

The invention relates to the technical field of agricultural ecology, in particular to an establishment material for recovering vegetation of cold-dampness type desertified grassland and a use method thereof. The vegetation establishment material is prepared from, by weight, 200-400 parts of cow dung, 100-200 parts of sheep manure, 500-1,000 parts of meadow soil, 100-200 parts of peat soil and 100-200 parts of bentonite, and is particularly suitable for recovering planting of the vegetation of the cold-dampness type desertified n grassland. As for plateau regions, yak dung can be directly used as one local raw material of the vegetation establishment material. The vegetation establishment material is added with water to ensure that during blending, the raw materials can be bonded to one another, and therefore the desertified grassland can be effectively covered, and meanwhile, more convenience is brought to excavation work in the later period. The establishment material for recovering the vegetation of the cold-dampness type desertified grassland and the use method thereof relate to the following approaches, steps and tools, and the steps consist of investigating a desertification diffusion direction in a desertified grassland region to determine the main movement orientation of a desert and then determine windward sides and leesides of fixed dunes, semi-fixed dunes and traveling dunes in an area where governance work is conducted, applying the vegetation establishment materials to the desert according to a usable area, and conducting monitoring and testing.

Description

technical field [0001] The invention relates to the technical field of agricultural ecology, and relates to a cold-damp desertification grassland restoration vegetation building material and a use method thereof. Background technique [0002] Desertification is a major problem of degradation of terrestrial ecosystems worldwide. Grassland desertification has increasingly become an important part of China's ecological construction in the western region of my country. Large areas of land and vegetation are desertified every year, and desertification has seriously threatened local ecological security, people's livelihood and frontier construction. Therefore, effective control and prevention of desertification is an important project of current ecological construction. Cold-humid desertified grasslands are more common in alpine regions, especially at the edges of watery areas in alpine regions, and desertified areas in areas with high rainfall are also very obvious. In the Thr...
