Abstract

A composite material for ecological construction consists of organic polymer, organic biological active material, organic refuse, nutrients for plant growth and slow-release and soil conditioning material. It can be used in semiarid region and desertification soil. It can improve plant growth environment, resist wind and water erosion. It is also cheap and non-toxic.

Description

technical field [0001] The invention relates to a composite functional chemical material for ecological construction. Background technique [0002] Affected by the climate environment and the intensification of human activities, the ecological environment of plants in my country, especially in the western region, has deteriorated and intensified, posing a major threat to people's production and life, and seriously threatening the sustainable development of my country's society and economy. Severe soil erosion causes siltation of rivers and lakes in the middle and lower reaches of the water system, increases in hanging rivers and lakes, reduces flood control and storage capacity, and aggravates flood disasters in the middle and lower reaches; at the same time, the imbalance and deterioration of plant ecology lead to natural disasters such as mudslides and strong sandstorms Frequent occurrence, and the trend of land desertification is intensifying. Therefore, improving and pr...
