| 摘 要： | 林木蒸腾作用与光照强度和土壤水分状况之间存在着密切的关系，蒸腾速率一般随光强的增强和土壤水分的改善而增大。因此，林木在苗期时，当土壤水分不足时，应采取措施避免强光照射，以减轻过度蒸腾失水造成生理伤害，提高成活率和促进苗木生长；有利于限制林木蒸腾失水，提高水分利用效率可考虑的土壤水分范围在１０％〈ＳＷＣ〈１５％之间。

| Abstract: | The transpiration is related closely
to irradiance and soil water,and generally,it is that the rate of transpiration is increased with
raising the irradiance and the soil water contant.Therefore,to lighten injuring on physiology as
transpiration seriously,to increase the rate of survivor and to promote growing,it is necessary
to adopt measure as avoiding violent irradiance of the saplings when the soil is short of
water.The soil water content as 10%
