根据田间试验实测资料分析了田间土壤水分的空间变化特征和时间动态变化,探索了监测农田水分变化时如何确定其合理的取样数目,讨论了农田尺度的土壤水分应如何监测,为节水灌溉,提高田间用水管理水平提供科学依据。
According to the data of field experiment, the spatial variation of soil moisture and the temporal dynamics of soil moisture were analyzed. How to determine the reasonable sampling number of soil moisture during the monitoring of farmland moisture was discussed, and how to monitor the soil moisture of farmland scale was discussed. Improve the level of field water management to provide a scientific basis.
