本研究测定了辽宁省5个主要土类及其上生长的大豆植株中微量元素含量,同时调查分析了东北三省4个土类不同的施钼方法,研究测定钼肥对大豆籽粒中微量元素Mo积累的影响。 研究结果表明,大豆植株含有丰富的B、Mn、Mo、Zn、Cu、Co、Fe、Pb、Ba、Sr等微量元素,其中Mn、Fe、Pb、Ba、Sr主要分布在叶片中;Mo、Co主要分布在籽粒中;大豆籽粒还会有相当数量的Zn、Cu和B。 耕作土壤上,大豆籽粒Mo含量与表土含Mo量存在良好的相关性. 施用钼肥不仅提高了大豆产量,而且提高其籽粒的含钼量。在不同的施钼方法中,喷施钼肥对大豆籽粒中钼的积累影响最大。
In this study, the content of trace elements in five major soils and soya plants grown in Liaoning Province were measured. In the meantime, four different molybdenum application methods in four soils of three northeastern provinces were investigated. The effects of molybdenum fertilizer on the trace elements Mo The impact of accumulation. The results showed that the soybean plants were rich in trace elements such as B, Mn, Mo, Zn, Cu, Co, Fe, Pb, Ba and Sr. Mn, Fe, Pb, Ba and Sr were mainly distributed in the leaves. Co is mainly distributed in the grain; soybean grain will also have a considerable amount of Zn, Cu and B. There was a good correlation between Mo content in soybean grain and Mo content in topsoil on cultivated soils, and application of molybdenum fertilizer not only increased soybean yield, but also increased molybdenum content in grains. In different molybdenum application methods, spraying molybdenum fertilizer had the greatest impact on the accumulation of molybdenum in soybean grains.
