本实验对藤稔/蜜汁两个品种进行处理。实验堆葡萄进行花前修剪和花后修剪各留3叶/4叶/5叶/6叶/7叶,以不修剪为对照,共11个处理,进行比较/分析。实验结果表明;花前修剪留4叶时两个品种产量均达到最高;有机酸含量在花期前修剪留6~7个叶时最低;可溶性固形物的含量与所留叶片数量成正比;修剪过程中,花前留6叶的含糖量最高,由此可见;最适宜的修剪方法为花前修剪留4~6叶,此时的产量与各种品质均可达到最优。
In this experiment, we deal with two varieties of rattan cake and honey cake. The pre-pruning and post-pruning grapes of the experimental reactor were left with 3 leaves / 4 leaves / 5 leaves / 6 leaves / 7 leaves, respectively, for comparison and analysis without pruning. The results showed that the yield of the two cultivars reached the highest when the 4 leaves were pruned; the content of organic acids was lowest when pruned 6 ~ 7 leaves before flowering; the content of soluble solids was proportional to the number of leaves retained; the pruning process , The pre-flower leaves 6 leaves the highest sugar content, we can see; the most appropriate pruning method for the pre-pruning leaves 4 to 6 leaves, this time the yield and quality can be achieved optimal.
