经国内外学者的研究,微量元素锰、钼、锌和硼,都是植物生长必须的微量元素。研究证明,锰能增加植物的呼吸强度,加强叶子的光合作用,从而促进植物生长。钼的生理作用主要在于参加蛋白质的代谢作用,加强荳科植物根部根瘤的发育,促进植物对氮的利用,从而增加产量。锌是植物组织内氧化酶活动性的必须元素。同 By domestic and foreign scholars, the trace elements manganese, molybdenum, zinc and boron, are all necessary trace elements for plant growth. Studies have shown that manganese can increase the plant’s respiratory intensity, enhance leaf photosynthesis, thereby promoting plant growth. The main physiological role of molybdenum is to participate in the metabolism of the protein to enhance the growth of root nodules in legumes and promote plant nitrogen utilization, thereby increasing production. Zinc is an essential element of oxidase activity in plant tissues. with
