摘要： 采用叶面喷施的方法，研究了硼锰钼配施对紫花苜蓿草产量和矿质元素含量及产量的影响。结果表明：硼锰钼配施可以提高紫花苜蓿干草产量，其中以单施钼产量最高，硼钼配施次之，与CK处理相比分别增产约54.75%、40.34%。硼锰钼不同配施对紫花苜蓿矿质元素含量及产量的影响不同，硼锰钼配施降低了苜蓿铁、锰、锌含量，其中以硼钼配施降低效果最显著；施微肥可以提高苜蓿铜含量，其中以硼锰钼配施效果最好；而硼锰、硼钼配施可分别显著提高硼、钼含量。硼锰钼配施提高了紫花苜蓿矿质元素产量，其中单施硼显著提高了苜蓿铁、锰、锌产量，单施钼、硼锰、硼钼配施分别显著提高了苜蓿铜、硼、钼产量。

Abstract: This paper studied the effect of combined application of boron, manganese, and molybdenum on grass yield and mineral element contents and yield of alfalfa by the method of leaf surface spurting. The result show that: different combined application all could improve the yield of alfalfa, among all the treatments the effect of single application Mo was the best, the follow was B and Mo combined application treatment, compared to CK, increase was 54.75%, 40.34%, respectively. Different B, Mn and Mo combined application has different influence on mineral element contents and accumulation amount of alfalfa. combined application micronutrient fertilizers decreased Fe, Mn and Zn contents, and B and Mo combined application has an obvious effect. But they could increase the Cu content of alfalfa, and the effect of B, Mn and Mo combined application was the best. B+Mn and B+Mo treatments could singificantly increaser B and Mo contents of alfalfa, respectively. Different combined application all could improve the mineral element accumulation amount of alfalfa. Single application of B could emarkably increase Fe, Mn and Zn accumulation amount, while single application of Mo and B, Mn and B, Mo combined application could significantly increase Cu, B and Mo accumulation amount of t alfalfa respectively.
