| 摘 要： | 秸秆还田是改良土壤的有效途径之一,秸秆的有效降解可以增强还田效果.利用黄孢原毛平革菌对玉米秸秆进行处理,分析不同粒径秸秆对N,P,K的释放情况,筛选出玉米秸秆还田的最佳预处理条件.结果看出,不同粒径秸秆在黄孢原毛平革菌的作用下,对N,P,K等营养元素的释放存在明显差异.粒径4～5 cm秸秆全N,P,K含量增长趋势明显,在第35 d时,全N,P,K含量分别为13.13,2.05和26.24 g/kg,增长率达到了103.70%,147.90%和62.90%.粒径0.5 cm秸秆的速效N,P,K含量增长趋势明显,在第35 d时,速效N,P,K含量分别为2.71,1.75和22.80 g/kg,增长率达到了289.52%,72.50%和37.71%.

| Abstract: | Straw returning is an effective way of soil amendment and effective degradation of the straw can enhance its effect.In a study reported in this paper,corn straw was pretreated with Phanerochaete chrysosporium,the release of nitrogen,phosphorus and potassium of corn straw of different granularity was analyzed and the optimum pretreatment conditions were screened.The release of N,P and K differed significantly in corn straw of different granularity under the influence of Ph.chrysosporium.Determined 35 d after... |
