葡萄当年能够在多级枝上形成花芽并能开花结果,因此可以利用副梢多次结果。葡萄一年多次结果在生产上具有一定价值,运用得当可增产10%以上。河北省中南部地区一般二次果都能成熟。虽二次果的果皮较厚,果粒较小。酸度稍大,但可延长鲜果供应期,果实耐贮运。葡萄枝芽受到冻害、花期遇雨、冰雹低温等自然灾害,授粉受精不良,座果率低,产量不足或无果的情况下,采用多次结果技术弥补产量损失,能获得较好的经济效益。 Grape was able to form flower buds on the multilevel branches and flowering fruit, so the secondary shoots could be used for many times. Grapes many times a year results in the production has a certain value, properly used can increase production of more than 10%. In central and southern Hebei Province, secondary fruit can generally be mature. Although the second fruit of the peel thick, fruit smaller. Slightly larger acidity, but can extend the supply of fresh fruit, fruit storage and transportation. Under the conditions of natural disasters such as frost damage, flowering rain, hail and low temperature, poor pollination and fertilization, low fruit set rate, insufficient yield or fruitlessness, the grape bud shoots can make up for the loss of yield and obtain better economic benefits .
