Leshan Shuiguo Township is located in Dadu River, Tsing Yi Wang Bank, soil sandy soil, the main peanut. Perennial planting area of more than 1,000 acres, mainly wheat peanut sets. Before 1983, because peanut varieties degenerated, mixed, and cultivation techniques lagged behind, the yield per mu was only 200 kg. In 1983, Shukou Township improved cultivation techniques and peanut yields rose from 200 kg to 347 kg in 1982. In 1984, the township summed up the experience of increasing production, focusing on the implementation of “six changes” measures to increase production more significantly. The average yield per mu of 1,002 mu of wheat peanuts was 438 kg. There have also been many high yield plots of more than 600 kg and 790 kilos each. Yields and total output doubled compared to 1982. The main experience of this rural wheat peanut doubled in two years is:
