| 摘 要： | 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.

| Abstract: | In order to explore the effect of moistube-irrigation method on navel orange ecophysiological parameters,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. |
