| 摘 要： | 利用盆栽油菜的二因素完全随机区组设计,研究了北方石灰性土壤上施用不同解磷菌群对土壤速效养分及土壤磷酸酶、脲酶活性的影响。结果表明:不同解磷菌群施入不同P素水平土壤中,油菜整个生育期内都能不同程度地提高土壤速效养分和土壤酶活性;土壤磷酸酶活性则随P素水平增高而降低,即低P水平下磷酸酶活性较强;施用菌肥土壤磷酸酶活性高于不施用菌肥处理,施与不施菌肥处理间脲酶活性在苗期及低P水平下差异显著。

| Abstract: | A pot experiment was conducted in a completely randomized block design to study the effect of different phosphate-dissolving groups of microorganism on soil nutrient and enzymatic activity of rape in the north lime soil.Results indicate that all the phosphate-dissolving groups of microorganism can increase soil available nutrient and soil enzymatic activity in the different treatments in rape breeding period.By increasing the level of phosphorus,soil phosphatase activity drops.Soil phosphatase activity is higher with bacterial manure application than without bacterial manure.There are significant differences in urase activity in rape seedlings at different levels of phosphorus. |
