| 摘 要： | 在氮磷钾基肥供应足量的基础上,采用叶面喷施的方法,研究Zn、Fe、Mo、Co、B、Cu、Se和Mn 8种微肥混合喷施对紫花苜蓿微量元素营养的影响。结果表明,喷施微肥能促进苜蓿Zn、Fe、Mo、Co、B、Cu、Se和Mn的含量及积累量的增长,且恰当的组配微肥中Mo和Co含量,如本试验的高钼低钴处理,能显著促进苜蓿8种微量元素的含量及积累量的同时增长(P<0.05)。

| Abstract: | Based on a regime of ample N,P,K fertilizer,the effect of 8 kinds of trace element fertilizers(Zn,Fe,Mo,Co,B,Cu,Se,Mn)with mixed spraying on trace element nutrition of Medicago sativa was investigated by spraying leaf surfaces.Spraying a mixture of trace elements increased the content and accumulating quantity of Zn,Fe,Mo,Co,B,Cu,Se,Mn.An optimal combination of mixed trace elements could considerably enhance the content and accumulating quantity of these eight elements(P<0.01).For example,there was a high Mo and low Co treatment in the experimental design. |
