1.采前处理:可在采前3～5天使用“防落1号”500倍液喷洒果穗,时间在晴天上午9—11时为好,喷后6小时内如遇降雨,需再补喷一次。 2.适期采收:葡萄没有明显的后熟期或后熟过程,所以供贮藏用的葡萄应在充分成熟时采收。一般以果粒外观、颜色和风味作判断标志,对于巨峰葡萄,较为准确的指标是:舍糖15％～17％;含酸0.8％～1.2％;糖配比16～20。
1. Pre-harvest processing: In mining 3 to 5 days before the use of “anti-drop No. 1” 500 times spraying spikes, the time in the sunny morning 9-11 as well, within 6 hours after the spray in case of rainfall, to make up Spray once. 2.
