钼是硝酸还原酶的重要。组成成分。动、植物在合成蛋白质时,首先需要将吸收的硝酸盐通过硝酸还原酶还原成铵后,方能为动、植物体吸收利用。因而钼能使动、植物体中的氮素顺利转化。由此可见钼是动、植物不可缺乏的微量元素。在我省不同土壤上进行钼肥试验,78个紫云英试验,增产幅度为0.65～99.25％,平均每亩增产鲜草368.2公斤:14个紫云英留种试验,增 Molybdenum is an important nitrate reductase. Composition. Moving, plants in the synthesis of protein, the first need to absorb the nitrate by nitrate reductase reduced to ammonium, before moving, plant absorption and utilization. Thus molybdenum can move, plant nitrogen in the smooth transformation. This shows that molybdenum is a moving plant essential trace elements. Molybdenum fertilizer tests were conducted in different soils in our province. 78 trials of Astragalus sinicus showed a yield increase of 0.65-99.25% and an average of 368.2 kg of fresh grass per acre: 14 species of Astragalus sinicus
