摘要： Soil moisture is one of the key factors which can limit crop growth. Based on the observation data of soil moisture and precipitation, during the 2005-2007 growing seasons, in the village of Jielin, about 10 km south of Dongxi town in northeast Sichuan hilly area, the relationship between soil moisture and precipitation under two crops farmed by conservational farming method was analysed. The crops were green pepper in ridge and wheat ridge in ground grid and solitary wheat. Both the duration and quantity of rainfall were considered. The statistical results of soil moisture showed that the change range of solitary wheat was 20.98. Precipitation lasted for different times, and each crop grew at changing speed, but the total trend was a gradual decrease. In addition, a comparison of different precipitation years showed that the average soil moisture has different changing patterns.
