Since the successful trial of Shihezi Reclamation Area in 1980, due to the remarkable increase in production and economic benefits, the popularization area of plastic film covers an area that has expanded rapidly in the past three years. At present, Has grown to 860000 acres. The development of the country is also very fast, the total area of plastic film planting more than 700 million mu. Plastic film cotton new technology has many advantages, it can increase ground temperature, promote cotton early, early strong, early peach; water and drought, anti-salinity; weed control fertility and so on. Premature, increase production, value-added effect is very significant. 80 years in Corps
