Abstract: By analyzing the correlation of weather conditions and annual average total soil moisture storage of every 10cm from soil surface to 50cm depth in soil.The results showed that,during crop growth period with precipitation and irrigation from 1986 to 2006,it was soil loses moisture stage in spring,which was the critical to water and fertilizer management.The conclusion could be used to forecast soil moisture and provide a scientific reference for agricultural management reasonably.
