生物焖棚对盐渍化设施土壤理化性质与微生物群落结构的影响
Effect of bio-stew management on the physicochemical properties and microbial community structure in salinized greenhouse soils
摘要
Abstract
This study aimed to explore the influence of bio-stew management(high temperature and organic materials+biological agent)on the soil quality of the vegetable greenhouses.Two treatments including conventional sealing(T1)and biological sealing(T2)were set up in Qingdao,Weifang,Liaoyang,Jiaxing and Hangzhou city.Soil chemical properties,soil aggregate structure,soil microbial community structure,soil microbial richness and diversity index,and soil microbial biomass carbon content were determined.The results showed that:Compared with T1,the contents of soil organic matter,alkali hydrolytic nitrogen,exchange copper and microbial biomass carbon for T2 were significantly increased by 19.55％,27.53％,58.43％and 37.52％(P＜0.05),respectively,and the mean weight diameter(MWD)of soil aggregates was significantly increased by 20.96％(P＜0.05).However,the effects on soil salinity,pH,available phosphorus and available potassium,and exchange zinc under T2 treatment were not significant(P＞0.05).The soil microbial community structure was changed by the microbial biomass carbon,microaggregates and soil salinity content.Due to the changes in soil's physical and chemical properties,the richness and diversity index of bacteria were increased by 15.06％(Chao 1),20.63％(PD),16.97％(Shannon),12.49％(Simpson),respectively.The richness and diversity index of fungi were increased by 17.63％(Chao 1),19.29％(PD),6.11％(Shannon)and 4.51％(Simpson),respectively.Meanwhile,the geometric mean value(GM)of soil quality was increased by 5.39％.Overall,this study suggest that biological sealing is beneficial for improving soil quality,soil microbial community structure and function compared to conventional sealing.Therefore,biological sealing is an effective measure to improve soil quality in salinized greenhouse soils.关键词
