【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、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:喷施复混微肥能促进苜蓿对Zn、Fe、Mo、Co、B、Cu、Se、Mn 8种微量元素的吸收,且适当组配复混微肥,能显著提高苜蓿对Zn、Mo、Co、B、Cu、Se的吸收量及积累量(P<0.05),极显著地促进Mo、Co、Cu、Se的吸收及积累(P<0.01)。更多还原

【Abstract】 Based on the ample N,P and K fertilizer,the experiment in the application effect of 8 kinds of mixed trace element fertilizers(Zn,Fe,Mo,Co,B,Cu,Se and Mn)sprayed on trace element’s nutrition of Medicago sativs was conducted.The results showed that the mixed trace elements could promote the absorbability of Zn,Fe,Mo,Co,B,Cu,Se and Mn,and the proper combination of mixed trace elements could markedly improve the absorbing and the accumulating quantity of Zn,Mo,Co,B,Cu and Se(P<0.05),and very much remarkably promote the absorbing and accumulating quantity of Mo,Co,Cu and Se(P<0.01).更多还原
