摘　　要：本文以双红、双优和左优红为试材,进行结果枝不同时期摘心的试验。结果表明,开花前10d和7d摘心,表现为坐果率和产量高,生理落果低。而在开花后摘心,则表现为坐果率和产量低,生理落果率高。因此,山葡萄品种的摘心时间适宜在开花前7～10d。Experiment was carried out by pinching beating branches in different periods on three varieties of Vitis amurensis Rupr.： Shuanghong, Shuangyou and Zuoyouhong. The results showed that pinching beating branches 10 days and 7days before blooming had higher fruit set rate and yield, and lower physiological fruit drop rate than treatment of pinching after blooming, So the optimal pinching period of Vitis amurensis Rupr. was 7-10days before blooming.
