Soil improving agent for ecological restoration of high-and-cold arid desertification soil and ecological restoration method

Abstract

The invention discloses a soil improving agent for ecological restoration of high-and-cold arid desertification soil. The soil improving agent is prepared from the following raw materials: in parts byweight, 50-100 parts of a microbial inoculant, 500-2000 parts of biological humic acid fertilizer, 20-100 parts of inorganic fertilizer, 50-150 parts of a water-retaining agent, 10-100 parts of palygorskite, 100-300 parts of bentonite and 10-20 parts of polyaspartic acid. The invention also discloses an ecological restoration method for high-and-cold arid desertification soil, and the method comprises the steps: applying the soil improving agent as base fertilizer to the soil at an applied amount of 100-200 kg of the soil improving agent to soil per mu, then performing rotary tillage and mixing, pouring water, and performing balance for 1-2 weeks so as to construct a plant community. The soil improving agent has the advantages that soil desertification can be managed effectively, the soilstructure and environment in high-and-cold arid zones can be improved, the plant growth in the zones can be promoted, the economic benefit can be increased, and the desertification control can be promoted.

Description

technical field [0001] The invention relates to the field of agricultural technology, more specifically, it relates to a soil improver for ecological restoration of alpine and arid desertification land and an ecological restoration method. Background technique [0002] Land desertification is one of the biggest environmental-socio-economic problems facing the world today. "Desertification" refers to land degradation in arid, semi-arid, and sub-humid areas caused by various factors including climate variability and human activities. my country is one of the countries most seriously affected by desertification in the world. The occurrence and development of desertification have caused serious harm to the ecological environment, natural resources, social economy and people's lives in vast areas of our country. The process of desertification development and reversal is the result of the interaction and coordination between human activities and the natural environment and resourc...

Problems solved by technology

Controlling desertification Chengyong grass grid sand-fixing, tree planting and other engineering methods, but generally can only achieve the effect of sand-fixing, how to restore the fertility of desertified soil to the effect of plant growth has always been a subject of research, especially for alpine and drought The soil in the zone is one of the difficulties in current research both at home and abroad.
