Formation of bald tips or few seeds. Corn lacks zinc, which affects the synthesis of chlorophyll. The growth of corn is hindered at the seedling stage, the leaves of the plant become smaller, and the plant dwarfs. This causes white corn seedlings, and at the flowering and pollination stage, zinc also plays a role in many enzyme reactions, because zinc also has vitality to pollen. It has a great impact. Therefore, zinc deficiency will cause poor fertilization and pollination of corn, resulting in lack of grain and baldness. Prevention methods 1.
