Effects of Co-inoculation of Arbuscular Mycorrhizal Fungi and Phosphate-solubilizing Bacteria on Phosphate Fertilizer Utilization Efficiency in Wheat
摘要
Abstract
The inoculation of inactivated fungi was used as the control,and a single factor randomized block design was used to analyze the effects of co-inoculation of two arbuscular mycorrhizal fungi(Rhizophagus irregularis,RI;Glomus intraradices,GI)and four phosphate-solubilizing bacteria(Bacillus amyloliquefaciens,BA;Bacillus megaterium,BM;Arthrobacter pascens,AP,Bacillus subtilis,BS)on wheat growth and phosphate fertilizer utilization efficiency.The results showed that:(1)Compared with the control,the colonization rate,yield and available phosphorus content of wheat were significantly increased,while the soil pH was significantly decreased.The yield and available phosphorus content were increased by 7.31%～27.00%and 19.03%～60.35%,respectively.(2)GI+AP had the highest yield.The content of available phosphorus and the alkaline phosphatase activity in the inoculation group supplemented with RI were higher than those in the inoculation group supplemented with GI,and RI+BS was the highest.The phosphate fertilizer utilization efficiency in RI+BS and RI+BA were 30.86%and 27.94%respectively.(3)Correlation analysis showed that the phosphate fertilizer utilization efficiency in wheat was extremely significantly positively correlated with colonization rate,grain weight,phosphorus content in grain,available phosphorus content and alkaline phosphatase activity,significantly positively correlated with leaf phosphorus content,and extremely significantly negatively correlated with soil pH.In conclusion,co-inoculation of arbuscular mycorrhizal fungi and phosphate-solubilizing bacteria could enhance soil alkaline phosphatase activity,increase soil available phosphorus content,decrease soil pH,and thus increase wheat yield and phosphorus accumulation.RI+BS had the most significant effect on improving the phosphate fertilizer utilization efficiency in wheat.关键词
