化肥减量配施微生物菌剂对蒙古黄芪产量、品质与土壤养分状况的影响
Effect of Fertilizer Reduction Combined with Microbial Agent on Yield,Quality and Soil Nutrient Status of Astragalus membranaceus var.mongholicus
摘要
Abstract
Objective:To improve the yield and quality of Astragalus membranaceus var.mongholicus by screening suitable fertilizer and microbial microbial ratio.Methods:The effects of fertilizer reduction combined with microbial agent on yield,active components con-tents and soil nutrient characteristics of Astragalus membranaceus var.mongholicus were studied in a randomized field experiment.Results:Compared with CK,fertilizer reduction(T1,T2)treatment could decrease the yield of Astragalus membranaceus var.mongholi-cus,but the difference was not significant.Under fertilizer reduction combined with microbial agent(T3,T4)treatment,the yield in-creased significantly,with a maximum increase of 35.26%;T1 and T2 treatment could decrease the contents of total saponins and total flavonoids,and increase the content of polysaccharides.T3 and T4 treatments could increase the content of active components,and com-pared with CK,the highest increase of total sapenins,total flavonoids and polysaccharides contents was 4.54%,14.38%and 37.19%,respectively.T1 and T2 treatments reduced the contents of soil organic matter,alkali-hydrolyzed nitrogen,available phosphorus and a-vailable potassium,and T3 and T4 treatments significantly increased the soil nutrient content.The content of total saponins was signifi-cantly correlated with the soil available potassium content,and the content of total flavonoids was significantly correlated with yield and extremely significantly correlated with organic matter content.Conclusion:The content of soil organic matter,alkali-hydrolyzed nitrogen,available potassium and available phosphorus can be effectively increased with 25%reduction of fertilizer and application of microbial microbial agent,and the yield and quality of Astragalus membranaceus var.mongholicus can be promoted.关键词
