| 摘要: |
| 通过对法引赤霞珠(Cabernet Sauvignon)、霞多丽(Chardonay)等15个酿酒葡萄品种采用不同的冬季修剪方法,从萌芽率、果枝率、结果系数等方面较系统地研究了其对修剪的反应。结果表明,作为供试栽培品种的预备枝,采用单、双芽修剪效果好;对结果母枝采用3～4芽的修剪,适合于大多数供试品种;中、长梢修剪(5芽以上)会造成严重的结果部位外移和内部光秃。 |

| Research on wine-grape reaction to winter-pruning |
|
|
| Abstract: |
| A research is conducted on the reaction of 15 wine-grape varieties introduced from France to winter-prune about sprout percent, fruit percent and fruit coefficient.The results show that the effect of single and dual buds pruning is best as replacing branch.The effect of 3-4 buds pruning suits for most wine-grape varieties studied.
The middle and long branch pruning (≥5 buds) results in fruit branch shifting outwards and inside bareness of tree. |
