葡萄幼树冬剪时,往往是人们用眼睛观察枝条成熟到哪就剪留到哪,待第二年春则发现大多数枝蔓先端的几个芽眼不能萌发。因而,只用眼睛来鉴别枝条成熟部位是不准确的。枝蔓先端芽眼不萌发的原因主要是枝条成熟度差,不能正常越冬。1987年,我对康太和黑奥林葡萄枝条粗度与新梢成熟度的关系进行了调查,并进行了相关、回归分析和 Grape saplings winter shear, people often use the eyes to observe where the branches mature where to leave, until the second spring is found that most of the branches of a few buds of the bud can not germinate. Therefore, it is inaccurate to identify only the mature part of the shoot with only the eye. The reason why the spur of bud is not germinated is that the branches are poor in maturity and can not winter normally. In 1987, I conducted a survey on the relationship between the shoot thickness and the shoot maturity of the Hongtai and Hongliao grapes and conducted correlation and regression analysis
