1.灌水时期.早春,在解除防寒物枝蔓上架后,即可灌水。这时灌水可防止枝蔓抽干,促进萌芽和新梢生长。开花前(5月末至6月初)灌水,保证花蕾生长健壮,开花授粉良好,提高坐果率。开花后至果粒着色前(6月末至8月初)灌水,有利于提高产量和改善葡萄的品质。当葡萄进入休眠期防寒培土前两三天(立冬左右)灌水,可防
1. Irrigation period. In early spring, after lifting the shelves of dehumidification shelves, it can be irrigated. At this time irrigation can prevent the branches and stems to dry, promote germination and shoot growth. Before flowering (end of May to early June) irrigation, to ensure robust flower buds, flowering and pollination, improve fruit set rate. Irrigation before flowering to fruit coloration (late June to early August) helps to increase yield and improve grape quality. When the grape into the dormant period of cold-resistant soil two or three days before the beginning (about winter) irrigation, prevent
