钼是一种微量元素,大豆是对钼较为敏感的作物,对钼的需要量比其它作物高出100倍。钼可以促进大豆根系发育,增强根系对养分的吸收能力,并提高植株的耐旱力;钼可以提高固氮酶的活性,提高根瘤菌固定空气中游离氮分子的能力,对大豆氮素代谢有重要作用,可增加蛋白质含量;大豆施用钼肥促进植株对磷的吸收、分配和转化,进而促进开花结荚,增加粒数、粒重。据有关试验表明,适当施些钼肥,可使大豆增产10%以上。
Molybdenum is a trace element, and soybeans are more sensitive to molybdenum crops, the demand for molybdenum 100 times higher than other crops. Molybdenum can promote the root development of soybean, enhance the ability of root to absorb nutrients, and improve the plant’s drought tolerance. Molybdenum can enhance the activity of nitrogenase and increase the ability of rhizobia to fix free nitrogen in the air, which is important for nitrogen metabolism in soybean Can increase the protein content; Soybean application of molybdenum fertilizer to promote plant absorption, distribution and transformation of phosphorus, and then promote flowering pod, increase grain number, grain weight. According to relevant tests show that some molybdenum fertilizer application, soybean yield can be increased by 10%.
