Description

It is a kind of that water-retention nanofiber degradable is green plants felt and preparation method thereof
Technical field
The invention belongs to Desert Control field of material technology, particularly a kind of water-retention nanofiber degradable is green plants felt and preparation method thereof。
Background technology
The living environment of the mankind and socioeconomic development have been arrived in the serious threat of desertification phenomenon, at present, China's desertification area has reached 2,620,000 square kilometres, account for the 27% of area, and in the situation of constantly extension, China is also one of country that desert area is bigger, distributed more widely in the world, desertification hazard is serious simultaneously。Desertification not only causes ecosystem unbalance, and makes arable area constantly reduce, and China's industrial and agricultural production and people's lives is brought and has a strong impact on。NORTHWEST CHINA arid biogeographic zone desert and desertification land, it has also become one of main seedbed of China or even Asian-Pacific area sandstorm, cause huge loss to national society's economy。Therefore, control of desert is country's urgent needs in ecological construction and environmental conservation。
Afforestation is the main path of Desert Control, but encounters insoluble problem in actual control of desert process, and one is that desert area wind-force is big, and sandy soil are loose easily mobile, just planted into plant cannot effectively take root fixing, survival rate is low;Two is that in desert, sand does not have water-holding capacity, and owing to the effect water evaporation quantity of sunlight is big, plant cannot survive because of hydropenia。In the face of control of desert, most expert also tries to strengthen the water-holding capacity in desert, and the measure taked includes irrigating and afforestation, but due to the sternness of above-mentioned desert problem, result is mostly failed, wastes a lot of manpower financial capacities。
In recent years, along with developing rapidly of nano material technology, nanofiber technology has become forward position and the study hotspot of fibre science, and nanofiber, due to the specific surface area of its super large, is widely used in the purification of the product such as chemical industry, medicine, filtration etc.。Current nanofiber product is applied in the report of various fields have been had a lot, but the research that nanofiber is applied to control of desert rarely has report。
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of water-retention nanofiber degradable is green plants felt and preparation method thereof, nanofiber technology is reasonably applied to control of desert field and environmentally safe, has been effectively increased the survival rate that Desert Green is planted。
