锌是作物生长发育必需的微量营养元素,在作物体内主要参与生长素(吲哚乙酸)的合成和某些酶系统的活动。缺锌影响碳水化合物的合成和新陈代谢作用,造成植株矮小,不利于种子的形成,使作物产量和品质下降。 1983年我所盆栽玉米施锌,地上部生物产量较对照增加9％,地下部重量增加21.1％。1984年在
Zinc is an essential micronutrient for crop growth and development. It is mainly involved in the synthesis of auxin (indole acetic acid) and the activity of certain enzyme systems in crops. Zinc deficiency affects the carbohydrate synthesis and metabolism, resulting in short plants, is not conducive to the formation of seeds, crop yield and quality decline. In 1983, my potted corn was applied with zinc, the above-ground biomass increased by 9% compared with the control, and the weight of the underground increased by 21.1%. In 1984
