摘　　要：采用盆栽称重法,通过对在干旱期间的土壤含水量分析了华北落叶松土壤水分含量的变化动态以及凋萎系数。结果显示,1 a中6月上旬土壤含水量最低,4月份和8月份为土壤含水量高峰期。华北落叶松的凋萎系数为4.83%,苗木从控水至暂时凋萎时间可以维持35 d.Change dynamics and wilting coefficient of soil water content of potted Larix principis-rupprechtii were studied.The results showed that soil water content was the lowest in the early June in a year.However,April and August were the highest.Wilting coefficient of Larix principis-rupprechtii was 4.83%.Seedling can resist drought of 35d from water control to temporary wilt.
