多菌灵对青贮玉米产量和真菌群落的影响
Effects of Carbendazim on Yield and Fungi Community of Silage Maize
摘要
Abstract
Carbendazim is widely used for prevention and control of leaf diseases in maize(Zea mays L.).However,the effects of different carbendazim concentrations on silage maize yield and fungal commu-nity structure were lack of research.In this research,serial dilutions of 1∶1500(low),1∶1000(medium),and 1∶500(high)carbendazim(80%active ingredient,wettable powder)solutions were applied to investi-gate their effects on silage maize agronomic traits and fungal community structure during three growth period(big trumpet stage,milk stage,and dough stage).The results revealed that compared with big trum-pet stage,the plant height and leaf area of silage maize were increased significantly at the milk and dough stages(P<0.05).Fresh weight per plant of silage maize under medium and high concentrations were decreased by 22.04%and 11.82%,respectively,compared with the low concentration.The contents of total phenolics,reducing sugars,vitamin C,free amino acid,and phosphorus,and mold count were signifi-cantly higher at the dough stage(P<0.05)compared with the big trumpet and milk stages.Carbendazim concentration had no significant effects on chemical properties of silage maze such as total phenolics,pro-line,reducing sugars,vitamin C,soluble protein,free amino acid,and phosphorus.Diversity analysis of fungi identified 186,186 and 202 OTUs under the application of low,medium,and high concentrations of carbendazim,respectively.At the genus scale,Symmetrospora,Papiliotrema,Hannaella,Filobasidium,and Cladosporium were the five fungi with the highest relative abundances.Under different carbendazim concentrations,the relative abundances of Symmetrospora,Phoma,and Hypoxylon varied significantly(P<0.05).The determination coefficient of vitamin C content for molds and soluble protein for yeast counts was the highest whereas free amino acid content was the lowest.Considering the yield,utilization pattern,as well as species and relative abundances of epiphytic fungi,the low concentration of carbendazim was recommended to be applied.关键词
