Abstract
Combined with the actual situation of Cangzhou City in Hebei Province, variation characteristics of soil moisture in Cangzhou City are analyzed with winter wheat and summer maize as the typical crops. It also reveals the variation and evolution trend of soil moisture and analyzes the monitoring data of soil moisture in Jiedi Test Station. Prediction scheme of increasing soil moisture is built by correlation method of P~ρ0~△ρ, and prediction scheme of decreasing soil moisture is built by correlation method of ρt~T~ρ0. Discussion on prediction methods of soil moisture content suitable for Cangzhou area is a promotional value for relevant study.关键词
