Junan Xian summer peanut plastic film mulching in successive years to obtain high and stable yield. Its yield-increasing mechanism is to improve the physical and chemical properties of soil, enhance the ability of drought resistance and waterlogging, promote the accumulation and rational distribution of photosynthetic products, increase the economic coefficient, solve the problem of accumulated temperature and improve the result rate and full-fruit index. The technology is to choose good conditions of fertile water plots, the implementation of formula fertilization, reasonable close planting, stubble early seeding, timely cover film, spraying plant growth regulators, timely pest control and drought prevention and premature senility
