基金项目:柴胡等9种中药饮片标准化建设（ZYBZH-Y-JIN-34）

中文摘要:目的：探究锰、钼、硼三种微量元素对黄芪生长指标、总多糖含量及生理特性的影响。筛选最佳的锰、钼、硼配比及合适的营养液浓度，为黄芪施肥过程中微量元素的施入提供一定的理论依据。方法：本试验采用三因素三水平正交试验设计，在保证其他营养元素用量一致的基础上，调整锰、钼、硼三种元素的用量，以黄芪的生长情况、总多糖含量及生理特性为评价指标。结果：0.48 mg·L-1的锰元素、0.54 mg·L-1L的钼元素和0.81 mg·L-1的钼元素组合条件下，更有利与促进黄芪的生长和物质积累。0.96 mg·L-1的锰元素、0.54 mg·L-1的钼元素和0.27 mg·L-1的钼元素组合条件下，更有利与增加黄芪总多糖的含量。0.48 mg·L-1的锰元素、0.54 mg·L-1的钼元素和0.27 mg·L-1的钼元素组合条件下，更有利黄芪生理指标及抗逆性的增加。结论：锰钼硼合理配施能促进黄芪生长和多糖含量的增加，并增加黄芪的抗逆性。以0.48 mg·L-1的锰元素、0.54 mg·L-1的钼元素和0.27 mg·L-1的钼元素组合条件作为基肥施入，可促进黄芪抗逆性的增加，生长旺盛期以0.96 mg·L-1的锰元素、0.54 mg·L-1的钼元素和0.81 mg·L-1的钼元素配比下进行叶面喷施，更有利与促进黄芪的生长和总多糖含量的增加。

Effects of Three Microscale Elements of Manganese，Molybdenum and Boron on Growth Index，Total Polysaccharide Content and Physiological Characteristics of Astragalusme mbranaceus

Abstract:Objective：To explore the effect of Mn，Mo and Bapplication amountand proportionon growth index，total polysaccharide content and physiological characteristics of Astragalu smembranaceus andprovide a basis formicroscale elements in the process of A.membranaceus fertilization.Methods：Three factors and three levels orthogonal test were adopted in this experiment.Onthe basis of ensuring the consistency of other nutrient elements，the amount of Mn，Mo and B in three elements was adjusted，and the growth index，total polysaccharide content and physiological characteristics of A.membranaceus were used as evaluation indexes.Results：Under the conditions of 0.48 mg·L-1 manganese element，molybdenum element of 0.54 mg·L-1 and molybdenum element of 0.81 mg·L-1，the growth and substance accumulation of A.membranaceus were more favorable and promoted.Under the conditions of 0.96 mg·L-1 manganese element，molybdenum element of 0.54 mg·L-1 and molybdenum element of 0.27 mg·L-1，the content of total polysaccharide of A.membranaceus were more favorable and increased.Under the condition of combination of 0.48 mg·L-1 manganese element，molybdenum element of 0.54 mg·L-1 and molybdenum element of 0.27 mg·L-1，the physiological index and stress resistance of A.membranaceus are more favorable.Conclusion：The reasonable application of manganese，molybdenum and boron can promote the growth of A.membranaceus and increase polysaccharide content，and the stress resistance of A.membranaceu .The molybdenum molybdenum manganese，combination of 0.48 mg·L-1 0.54 mg·L-1 and 0.27 mg·L-1 as basic fertilizer，can increase the resistance of A.membranaceus.At the vigorous growth period，molybdenum and manganese can promote the growth of A.membranaceus and total the content of polysaccharide.
