摘要:
以8年生黄冠梨为试材，在黄冠梨不同生长期采用调亏灌溉的灌水方法，研究了滴灌模式下轻度与重度调亏灌溉对黄冠梨叶片含水量及叶绿素含量的影响。结果表明：不同时期的调亏灌溉降低了梨树叶片叶绿素含量和叶片相对含水量，增加了叶片的自然饱和亏；复水后，在新梢速长期，轻度调亏处理的叶片叶绿素含量和叶片相对含水量和对照差异不显著；在新梢速长期和幼果期的重度调亏处理，其叶片叶绿素含量和叶片相对含水量和对照差异显著。在新梢速长期对黄冠梨采取调亏灌溉处理可以减少灌水量，同时对黄冠梨树的生长发育没有影响。
Abstract:
Eight-year-old Huangguan pear were taken as test material and regulated deficit irrigation method was used in different growth periods of Huangguan pear.The effects of mild and severe regulated deficit irrigation under drip irrigation mode on leaf water content and chlorophyll content were studied.The results showed that the regulated deficit irrigation could reduce chlorophyll content and relative leaf water content in different periods,which increased the natural saturation deficit of the leaves.After rewatering,chlorophyll and relative leaf water content of mild regulated deficit irrigation were not significantly different from CK in new shoot rapid growth period.And chlorophyll and relative leaf water content of severe regulated deficit irrigation were significantly different from CK in new shoot rapid growth period and young fruit period.In conclusion,it could not only reduce irrigation water but also take no effects on growth of pear that regulated deficit irrigation on Huangguan pear in new shoot rapid growth period.
