为探明微润灌溉对脐橙生长过程中生理生态参数的影响，对微润灌溉、常规灌溉和雨养灌溉3种灌溉方式下的脐橙叶片最大光合速率（ Amax ）、叶片呼吸（ rd ）、表观初始量子效率（α）、光补偿点（ Lcp ）、叶片的比叶面积（ SLA）等生理生态参数进行了测定和对比分析。研究结果表明，在其他条件相似的情况下，采用微润灌溉的方式对脐橙叶片Amax、rd、α、SLA的促进作用最为明显，常规灌溉次之，雨养灌溉下值最低。叶片的Lcp在微润灌溉方式下最低，常规灌溉和雨养灌溉下的该值依次递增。

In order to explore the effect of moistube-irrigation method on navel orange ecophysiological pa-rameters,the ecophysiological parameters of navel orange were measured under three irrigation methods ( moistube-irrigation,conventional irrigation and rain-fed irrigation ). The maximum photosynthetic rate (Amax),leafrespiration(rd),apparent quantum yield(α)and specific leaf area(SLA)had the highest values with the moistube-irrigation method,and we found that the values were lower with the conventional irrigation and the values were lowest with rain-fed irrigation. However,light compensation point( Lcp )was lowest with rain-fed irrigation,and highest with moistube-irrigation.
