摘要
利用油松和山杏光合生理参数与土壤水分定量关系的研究结果,提出大青山阳坡土壤水分对两树种有效性的分级阈值,结合生长季林地土壤水分的动态测定结果,对土壤水分有效性进行了评价,认为两树种在2010年和2011年的2个生长季内均受到严重的水分胁迫。
According to the results of study on the quantitative relationship between soil water and photosynthetic physiological parameter of Pinus tabulaeformis and Prunus armeniaca,the range values of validity grades of soil water for the two kinds of trees have been put forward.In the light of the results of dynamic measurement on soil water in woodland,the two kinds of trees grew with serious water stress in the growth season of 2010 and 2011.
