为解决山葡萄栽培中夏季修剪费工费时问题 ,我们于 1 999和 2 0 0 1年对“双优”、“左山二”、“双丰”3个品种的成龄树进行了夏剪试验。结果表明 ,山葡萄结果枝在花前摘心时留 3～ 5片叶摘心 ,不留副梢 ,可减少夏季摘心用工量 30 %以上 ,对果实产量及品质无不良影响 ,其中以留

A trial for the pruning in the growth period of bearing tree of Vitis amurensis Rupr.among these three varieties-ShuangYou,ZuoShan No.2 and ShuangFeng was conducted in 1999 and in 2001 in order to solve the problems of time consuming and work consuming of the pruning in the growth period of Vitis amurensis Rupr.The results showed that this method could lower more than 30% of total work load without bad effect on yield and quality of fruit as reserving 3～5 leaves before blooming in the fruit bearing branch with no accessory shoot.To reserve 5 leaves was the best.
