Abstract: In order to better evaluate the Shandong agricultural meteorological station, research on regulation of soil water movement, according to the data from 120 moisture measurement stations in Shandong Province, the author measured different soil texture and wilting coefficient, using Van Genuchten model to describe soil water characteristic curve (h-? curve) to establish the connection between moisture volume ratio and soil water potential based on agricultural meteorological automatic observatory of Shandong Province. The comprehensive analysis indicated that: sticky soil had higher stable and effective water content in field than sand, so the sticky soil could stably provide water to plant and coordinate water themselves, thus sticky soil had a strong ability in resistance to drought and flood.
