Nanchong City, Sichuan Province, is a water-poor area. It often affects the normal planting of Dachunchun crops due to insufficient agricultural water. In particular, in high-altitude village communities, once a drought occurs, farmers will have to postpone their time or find water due to lack of water. Childbirth has increased both the cost of raising the eel and seriously hindered the large area of ​​rice production. In order to save water for agriculture and ensure the timely implementation of rice production in the city, we have used the feature that plastic membranes can retain water, combined with the knowledge of soilless cultivation, and carefully designed rice plastic film water-saving technology. This technology was successfully tested at the beginning of 2000. Large-scale demonstrations began in 2001 and it has been widely promoted throughout the city. The area of ​​promotion is at least 100,000 mu per year. This technology is compared with similar technologies that are widely used in Nanchong City. The advantages are outstanding: First, the water resources can be recycled, saving a lot of water for raising seedlings; Second, it can be well insulated and protected against cold, and it is advantageous for early sowing. Third, it can reduce the rotten seed, rotten seedlings, and dead and dead seedlings; Fourth, it can save rice seeds: The fifth is that the cultivated seedlings return green and fast after being planted, and the tillering power is strong. The increase in yield is significant. Sixthly, less investment, low use cost, simple technology, and easy promotion, are currently a good breeding technique in rice production. In order to enable the technology to be promoted in larger areas and promote rice production and income increase, the technical points are introduced as follows.
