| 摘 要： | 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，铺膜效果优于搞叶处理。
