摘  要：
为了在准确把握土壤墒情信息的前提下,简化土壤剖面水分的测量,减少传感器的埋设数量,对蓄水坑灌果园水分测点优化布设进行研究。结果表明:不过坑且距离果树30cm处监测点(b30)的体积含水率和整个试验区10个监测点体积含水率的加权平均值有着显著的相关性,并且两者之间的关系可用线性公式表示,进一步利用相同处理的不同果树的相关数据进行验证,结果表明所建立的线性公式具有较高的预测精度。因此,可以利用b30测点的体积含水率来估算蓄水坑灌条件下整个果树周边土壤的含水率情况。

摘  要：
In order to simplify the soil profile moisture measurement and reduce the number of embedded sensors under the premise of accurately grasping the soil moisture information,the layout of fruit trees moisture-measuring points under the water storage pit irrigation are studied.The results show that there are obvious correlation between the volumetric water content of the monitoring point which does not across the pit and of fruit trees 30 cm distance(b30)and the average volumetric water content of the whole fruit tree and linear formula can be used to show the relationship between them.Meanwhile,the result of the verification of other fruit tree with the equal condition also indicates the linear formula which is established with high prediction accuracy.Therefore,the volumetric water content of the monitoring point of b30 can be used to estimate fruit trees surrounding soil moisture conditions under the water storage pit irrigation.
