微量元素钼在大豆栽培中得到广泛应用并已获得良好效果,其在大豆生物固氮中的作用机理也比较清楚。国外也有学者研究微量元素钼在大豆植株内运转的特点,及钼在籽粒中的含量对维持根瘤含量的重要性;而且也有人研究微量元素镁、锌、硼、锰、钴、铁、铜对大豆产量的影响以及微量元素对大豆生物固氮的促进作用。在我国黑龙江大豆种植
Trace element molybdenum has been widely used in soybean cultivation and has achieved good results, and its role in soybean biological nitrogen fixation is also relatively clear. Some foreign scholars also study the characteristics of trace element molybdenum in soybean plant operation, and the content of molybdenum in the kernel to maintain the importance of nodulation; but also some people study the trace elements magnesium, zinc, boron, manganese, cobalt, iron, copper The effect of soybean yield and the promotion effect of trace elements on nitrogen fixation of soybean.
