摘要： In order to establish rational soil moisture monitoring system for under film chip irrigation. With samples taken with grid sampling method and random sampling method at the field of 148 Tuan of Div 8th (Shihezi area) in Xinjiang and the soil moisture data obtained along fie different depth underground, which are then analyzed with typical statistic methods, the methods to determine the numbers and the distribution mode of sampling points are put forward and fie relative errors of soil moisture contents gained with different sampling types and numbers are analyzed in the paper.
