硼属于蔬菜生长发育过程中所必须的微量元素。具有促进叶绿素的形成和糖的合成与运输的功能,还可促进花粉提前萌发,加快受精和种子的形成,能显著增加产量。蔬菜如果在生长发育过程中缺硼,表现出根系生长差,生长点死亡,花发育不全,果实畸型,影响产量和品质。 不同的蔬菜缺硼,其表现出的症状不同。如大白菜缺硼叶柄呈黄色;花菜、萝卜缺硼易患“褐腐病”,芹菜缺硼产生茎裂,黄瓜缺硼植株矮小,侧茎形成加快,
Boron belongs to the necessary trace elements in the process of vegetable growth and development. It has the function of promoting the formation of chlorophyll and the synthesis and transport of sugar. It also promotes the early germination of pollen, accelerates fertilization and the formation of seeds, and significantly increases the yield. If the lack of boron in the process of growth and development of vegetables, showing poor growth of the root system, the growth point of death, flower hypoplasia, fruit abnormal, affecting yield and quality. Different vegetables lack boron, which show different symptoms. Such as cabbage lack of boron petiole yellow; cauliflower, radish boron deficiency susceptible to “brown rot”, celery boron deficiency produce stem split, cucumber boron deficiency plants short side, the formation of side stems accelerated,
