摘要
选用5年生红地球和弗雷无核,进行了集约化管理模式下的定穗、疏果、套袋等花果管理实验,通过比较不同定穗方式、疏果标准、疏果方法和套袋类型,确定了适宜的鲜食葡萄花果管理集约化技术。定穗时弱枝不留果、壮枝留1穗果,红地球葡萄结果枝不做连续结果,弗雷无核壮结果枝可做连续结果;疏果时可在花前拉长果穗的基础上用"两剪拉臂式"疏果方法进行,红地球葡萄每穗留60粒果,弗雷无核每穗留80粒果;在西部地区应选用无纺布袋作为葡萄套袋,在起到防病、防水、防尘作用的同时,避免成熟延迟、果粒变小和日灼等现象的发生。
Fruit management experiments including cluster thinning, berry thinning and cluster bagging were conducted on five-year- old Red Globe and Flame Seedless. Effects of different cluster thinning strategies, berry thinning standards, berry thinning protocols, and bag materials on fruit quality and operating effeciency were compared to determine the appropriate intensive fruit management protocol. Only strong shoots can burden fruits with one cluster per shoot. Fruiting cane of Flame Seedless can burden continuously, while that of Red Globe can not. A ＂Two-cut＂ thinning protocol can be employed in berry thinning by elonging the cluster before florescence, The appropriate berry numbers per cluster for Red Globe and Flame Seedless are 60 and 80 respectively. Mekralon cluster bag was more suitable than paper cluster bag in West China. It＇s effecient in protecting clusters from fungi disease and water or dust pollution, and erasing the disadvantages such as ripening-delay, berry lessening, and sunburn that usually occurring inside paper cluster bag.
