锰、锌、铜、硼及钼五种微量元素在大豆上喷施,不管对大豆的营养生长或子实产量均有显著的效果。在营养生长上如叶数、根及根瘤风干重,一般比对照提高17.5—32.6%。子实产量方面以Mo、Zn两处理最好,分别比对照提高20.9%和20.7%,其次为Cu、Mn、B,分别提高14%、9.9%和6.6%。喷施微量元素各处理子实的千粒重和油脂及氮的含量,也一般比对照有所增长,可见它们对大豆品质的提高也有良好作用。喷施微量元素所收获的子实,其发芽力也比对照有所增加。
Manganese, zinc, copper, boron and molybdenum five kinds of trace elements sprayed on the soybean, regardless of the vegetative growth of soybean or fruit yield have significant effect. In vegetative growth, such as the number of leaves, roots and root nodules air dry weight, generally higher than the control 17.5-32.6%. In terms of seed yield, the treatments of Mo and Zn were the best, increasing by 20.9% and 20.7% respectively than the control, followed by Cu, Mn and B by 14%, 9.9% and 6.6% respectively. Spraying of trace elements in each treatment of the grain weight of 1000 and oil and nitrogen content, also generally increased compared with the control, we can see that they also have a good effect on the quality of soybeans. Spraying trace elements harvested fruit, its germination power also increased compared with the control.
