With the development of furrow gutting technology, the area of continuous no-tillage in paddy field has been expanding year by year in our province. According to incomplete statistics, there is currently only 1 million mu of continuous no-tillage rice field in Changning County, The trend of increasing year by year is very obvious. According to the fixed-point observation of 64 households, the average mu production was 480.25 kg in 1983 and 554.85 kg per mu in 1986, an increase of 15.5% over 1983. Continuous no-tillage forms and practices are the following: 1, medium rice - fish (Ping) - ratooning rice. Xiangling Township, a group of Xinqiao Cun civilization, Hou Shuan Kuan and a group of five-star Chen Dongcai in the field of raising good Ping to 2 feet open Ridge Ridge 埂 埂 8 inches high, 1-inch wide and 2 inches wide, the first Base fertilizer, mu with pure nitrogen 15 pounds, P_2O_57 pounds, K_2O7 pounds mixed in the castration, and then covered with mud covered with fertilizer fertilizer, its purpose is to rice paddy fish symbiosis, so that rice double harvest, the use of fish
