[目的] 研究摘叶、铺膜以及摘叶结合铺膜处理对赤霞珠葡萄叶片光和性能的影响.[方法] 以7年生赤霞珠葡萄为试材,设摘除果穗周围叶片、树冠下铺银色反光膜、树冠下铺银色反光膜+摘叶3个处理,以常规管理株为对照,分别测定4个处理的叶片光合速率(Pn)、气孔导度(Gs)和细胞间隙CO2浓度(Ci)以及光照强度.[结果] 摘叶和铺膜处理均可提高葡萄结果部位叶片的光合速率,其中摘叶处理比对照提高28.3%,铺膜处理比对照提高72.6%;铺膜+摘叶处理相对于铺膜或摘叶处理并未表现显著的加和效应,摘叶和铺膜处理对叶片气孔导度有一定影响,以摘叶处理影响较大.不同时期各处理叶片细胞间CO2浓度存在一定差异.[结论] 综合考虑,铺膜效果优于摘叶处理.

[Objective] The aim was to study the effect of picking leaves,paving reflecting film and leaf picking combined with paving reflecting film on photosynthetic characteristics of leaves of Cabernet sauvignon grapes. [Method] With 7-year-old C. sauvignon grapes as the test materials,3 treatments of picking the leaves around the fruit,paving the silver reflecting film and leaf picking combined with paving reflecting film were set up and the conventional management plants were taken as the CK. The leaf photosynthetic rate (Pn),stomatal conductance (Gs),intercellular CO2 concn(Ci). and light intensity of 4 treatments were measured,resp.. [Result] The treatments of picking leaves and paving reflecting film all increased the Pn of leaves in setting fruit position of grapes. Compared with CK,Pn of leaves with picking leaf treatment was increased by 28.3%,and that with paving reflecting film treatment was increased by 72.6%. Compared with the treatment of paving reflecting film or picking leaves,there was no significant additive effect with paving film + picking leaves treatment. There was a certain influence of paving reflecting film and picking leaves treatment on leaf Gs and the effect of picking leaves was great. There were some differences on the Ci. of leaves at different times in all treatments. [Conclusion] In general,paving reflecting film had a better effect than that of leaf picking.
