土壤酸性磷酸酶与微生物群落结构对磷素养分变化的响应
摘要
Abstract
Soil acid phosphatases and microbial communities are closely related to phosphorus nutrients.Experiments were conducted to study the responses of soil acid phosphatase genes and microbial communities to changes in phosphorus indicators.The results showed that:When the soil available phosphorus content changed from 14.63 mg/kg to 110.70 mg/kg,there was a significant positive correlation between acid phosphatase and available phosphorus(P<0.05).When the available phosphorus content changed from 14.63 mg/kg to 213.93 mg/kg,there was no significant correlation between acid phosphatase and available phosphorus;the response of soil acid phosphatase to changes in the available phosphorus/total phosphorus ratio was similar to that of available phosphorus;the correlation between soil acid phosphatase and total phosphorus was not significant.Soil available phosphorus,available phosphorus/total phosphorus,etc.showed extremely significant correlations with 19 phosphorus-solubilizing bacterial genera(P<0.001),acid phosphatase showed extremely significant correlations with 3 genera(P<0.001),and total phosphorus showed extremely significant correlations with 9 genera(P<0.001).RDA analysis showed that the four soil phosphorus indicators accounted for 94.05%of the variation of phosphorus dissolving microbial genera,and all had a very significant impact on soil phosphorus dissolving microbial genera(P<0.000 5).关键词
