为提高山葡萄生产栽培果实质量和产量,以双红、双优和左优红为试材,进行单株不同留果量的试验。结果表明:随着单株留果量和产量的增多,植株萌芽率、穗重、粒重、果实含糖量和出汁率大幅度降低,而果穗小青粒和果实总酸大幅度增高;适宜的单株留果量为50～70个。 In order to improve the quality and yield of the fruit cultivated and cultivated in mountain grape, double red, double excellent and left red for the test material, the amount of individual fruit retention test. The results showed that the germination rate, panicle weight, grain weight, fruit sugar content and juice yield decreased sharply with the increase of the amount and yield of single fruit per plant, but the total acidity of small fruit and fruit increased significantly The number of leaves per plant is 50 ~ 70.
