摘要：

A review of the possible methods of measuring soil water content under high frequency trickle irrigation suggested that the gravimetric method was most appropriate. Three sources of errors in this method have been evaluated and discussed. The sources are those of water content by weight, bulk density, and integration based on the sampling grid.
