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
Effects of Three Microscale Elements of Manganese,Molybdenum and Boron on Growth Index, Total Polysaccharide Content and Physiological Characteristics of Astragalusme mbranaceus
摘要
Abstract
Objective:To explore the effect of Mn,Mo and Bapplication amountand proportionon growth index,to-tal polysaccharide content and physiological characteristics of Astragalu smembranaceus andprovide a basis formicroscale ele-ments 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 ele-ments 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-1manganese element,molybdenum element of 0.54 mg·L-1and 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-1manganese 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 in-creased.Under the condition of combination of 0.48 mg·L-1manganese element,molybdenum element of 0.54 mg·L-1and 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-10.54 mg·L-1and 0.27 mg·L-1as basic fertilizer,can increase the resistance of A. membrana-ceus.At the vigorous growth period,molybdenum and manganese can promote the growth of A.membranaceus and total the con-tent of polysaccharide.关键词
