玫瑰香葡萄在生产上存在着座果率低、果实松散、稀稀拉拉、穗形不美观等弱点。为了研究这一问题,我们分别选30年生和8年生的玫瑰香葡萄作试材,设置了6个处理,每一处理5株,对主梢进行不同时期的摘心,每株选4穗调查其座果率和测定其可溶性固型物。其结果如表1。 在葡萄花蕾进入初开花时(5月中旬),一般新梢展12—16片叶,其上的夏芽萌发8个左右,这样在一个主梢上就有8—9个生长点继续延长生长,一个要开花,一个要生长,在营养分配上就发生了矛盾。这对矛盾,在座果率低的玫瑰香葡萄品种上表现的比较突出。
Muscat grapes in the production there is a low fruit yield, loose fruit, sparse larvae, spike unsightly and other weaknesses. In order to study this problem, we selected three-year-old and eight-year-old rose grapes as test materials, set up six treatments, each dealing with five strains of the main shoots at different times, Fruit set rate and determination of its soluble solids. The results are shown in Table 1. At the beginning of the flowering grape bud (mid-May), the general shoot 12-16 leaves exhibition, the summer bud on it about 8, so that in a main shoot there are 8-9 growing point to continue to grow One must bloom and one grows, contradicting the distribution of nutrients. This contradiction, in the low rate of fruity grape varieties show more prominent.
