| 摘 要： | 检测了四川省凉山州会理烟区土壤肥力及根际微生物数量,研究了两者之间的相关关系.利用多因子及互作项逐步回归方法得到肥力因子与微生物数量的回归方程.偏相关和通径分析结果表明:在烟草的团棵期,碱解氮与速效钾的正互作效应以及有效磷与pH的正互作效应与细菌数量呈正相关;旺长期,细菌数量与pH无显著相关性,与碱解氮、有效磷、速效钾、有机质的含量均呈显著相关;成熟期,碱解氮与细菌数量呈显著正相关.团棵期,有效磷与pH的正互作效应以及有机质与pH的正互作效应与真菌含量呈正相关;成熟期,碱解氮与真菌含量呈显著正相关性.不同时期的放线菌含量与有机质、pH以及有效磷具有相关性.说明在烟草的不同生长期,各种微生物数量与肥力因子的关系各不相同;同一生长期,不同种微生物量与肥力因子的关系也有很大差异.

| Abstract: | The quantitative correlations between the soil fertility factors and microbial biomass were studied by the analysis of the soil fertility and microbial biomass contents collected from Huili tobacco growing areas of Sichuan Province. Polyfactorial regression analysis showed that different kinds of soil fertility factors could affect the contents of different kinds of microbial biomass. There were no significant correlation between pH and the content of bacteria in vigorous period, but the other four soil fertility factors were correlated with it. The available nitrogen was positively correlated with the content of bacteria in maturity period. Partial correlation and path analysis suggested that the interaction effects of available phosphorus and pH were positively correlated with the content of fungi in group pieces, also the significant effects of organic matter and pH were discovered. There were obvious interaction effects of available nitrogen and fungi in maturity period. The results also showed that actinomycetes had a correlation with available phosphorus, organic matter and pH in three different periods, and the relationship between soil fertility factors and microbial biomass was different. |
