摘要
在干旱胁迫和不同施肥处理条件下,用Flow4 TM茎流计测定了4个抗旱树种白榆(Ulmus pum ilaL.)、女贞(Ligustrum lucidumA it.)、刺槐(Robinia pseudoacaciaL.)和元宝枫(Acer truncatumBge.)的树干茎流量。结果表明,施肥处理对各树种日蒸腾量和日茎流量影响显著,其中对元宝枫和白榆的影响最大。
By using Flow4 TM sap flow system, sap flows and transpiration of Ulmus pumila L. , Ligustrum lucidum Ail, Robinia pseudoacacia L. and Acer truncatum Bge with different fertilization treatments were measured under drought stress. The results showed that the effect of fertilization on diurnal transpiration and diurnal sap was obvious, and the effect on A. truncatum and U. pumila was most significant.
