采取合理的促控技术,可使巨峰葡萄提前成熟,提早上市,提高经济效益。具体技术措施如下: 1、适期控氮、控水。当葡萄座果后,叶片数量和叶面积已经达到要求,在施肥上要适当控氮,一般在进入果实第一次膨大期要少施、甚至停止施用氮肥,追施磷肥,以促进叶片增厚和果实膨大,利于整个树势由营养生长向生殖生长过渡。当果实进入第二次膨大期之后,则要注意适当控制浇水,以免贪青晚熟。在控水上要做到“三看”。即看天、看树、看果。看天是指在雨水勤时少浇或不浇水;看树是指树势旺而密蔽则少浇水;看果是指果实膨胀迅速时少浇水。
Adopting reasonable promotion and control technology can make Kyoho grapes mature in advance and go public early to increase economic benefits. Specific technical measures are as follows: 1, the appropriate control of nitrogen, water control. When the grape fruit, the number of leaves and leaf area has reached the requirements in the fertilization should be appropriate nitrogen, usually in the first expansion into the fruit to less Shi, or even stop the application of nitrogen fertilizer, topdressing phosphate fertilizer to promote leaf thickening And fruit enlargement, which will benefit the entire tree by the vegetative growth to reproductive growth transition. When the fruit into the second expansion period, we must pay attention to proper control of watering, so as to avoid greyish late maturing. To control the water to do “three see.” To see the sky, see the tree, see the fruit. To see the sky refers to the time when the rain poured less or not watering; see the tree is strong and the tree is less dense watering; see fruit refers to the rapid expansion of fruit less watering.
