一、症状及原因 葡萄谢花期,花朵顶部的花冠脱不掉,座果少,果粒稀疏。果穗中,产生许多小型的“豆粒果”,果粒发育不整齐,并在后期大粒果面出现干斑,造成早期脱落,这主要是缺硼引起的。葡萄缺硼时,花芽发育不良,花序瘦小,授粉受精不正常,落花落果严重。葡萄缺硼症也称葡萄小粒病 First, the symptoms and causes Grape thanks to the flowering period, the top of the flower corolla can not afford to lose fruit, fruit sparse. In the ears, many small “bean grains” are produced, and the fruit grains are irregularly developed, and dry spots appear on the large grain surface at the later stage, resulting in early shedding, which is mainly caused by boron deficiency. Grape lack of boron, flower buds poorly developed, small inflorescences, pollination and fertilization is not normal, falling seriously. Grape boron deficiency also called grapes disease
