Jianping County is a mountainous agricultural county located in western Liaoning. It has arid climate, short frost-free period, large temperature difference between day and night, and the drought always plagued and restricted the development of agriculture in Jianping County. In order to make the grain yield in Jianping stable, solve the problems of short frost-free period, lack of moisture and drought caused by the drought, the introduction of mulching cultivation techniques has achieved remarkable success in agricultural production. By analyzing the natural climatic conditions in Jianping County, the history of the development of plastic film mulching, practical measures of work and cultivation techniques and measures have been taken and significant economic and social benefits have been achieved. At the same time, the technical advantages of mulch film mulching cultivation were analyzed and relevant development countermeasures were put forward.
