摘要
为提高山葡萄(Vitis amurensis Rupr.)主栽品种双红、双优和左优红的果实品质和产量,对结果枝进行了不同留叶数的摘心试验。结果表明:留2片叶摘心,3品种均表现出坐果率、果穗重、含糖量、出汁率和产量偏低,果粒重和总酸高;留3～5片叶摘心,果穗重、含糖量、出汁率较高,总酸含量较低,坐果率和产量中等;留6～7片叶摘心,坐果率、产量和总酸较高,但果粒重、果实含糖量和出汁率较低,果穗松散,而且增加了夏季修剪的用工量。
Experiment was carded out by pinching of bearing branches for increasing yield and improving fruit quality of three varieties of Vitis Amurensis Rupr.： ‘Shuanghong＇, ‘Shuangyou＇ and ‘Zuoyouhong＇. The results showed that fruit set rate ,cluster weight, sugar content, juice rate and yield were low for 2 leaves pinching in three varieties. Cluster weight, sugar content, juice rate were high; total acid content was low; fruit set rates and yield were moderate while 3-5 leaves were leaved on the bearing branches. Fruit set rates ,yield and total acid content were high, but berry weight, sugar content and juice rate were low for 6-7 leaves pinching, cluster apperars relax, and more workload in summer pruning.
