| 中文摘要 |
| 为提高堆肥产品中可利用磷素含量，采用不接种解磷菌剂、不添加磷矿粉处理（CK），不接种解磷菌剂、添加磷矿粉处理（CP），接种解无机磷菌剂、添加磷矿粉处理（CMP）3种处理进行了堆肥试验，并对堆肥不同时期样品中磷组分的动态变化进行分析.结果表明，与CK比较，在堆肥不同时期，CMP、CP处理有机态磷、水溶性磷、速效磷均呈不同程度的增加.堆肥结束后，CP、CMP处理有机态磷、水溶性磷、速效磷与CK比较的增加值分别为2 049.8、4 188.6mg/kg，264.2、648.7 mg/kg，954.0、3 576.4 mg/kg，其中CMP处理分别是CP处理的2.04、2.46、3.75倍.试验结果证明，采用高温解无机细菌接种，可明显促进堆肥中添加难溶性磷矿粉的转化效率，提高堆肥产品中植物可利用磷素含量. |
| 英文摘要 |
| In order to enhance the available phosphorus (P) of compost production, the experimental design of composting included three treatments was conducted. The treatments were: Control (CK) with no dissolved phosphate microbes inoculation, no rock phosphate mixing; CP with no dissolved phosphate microbes inoculation, rock phosphate mixing; CMP with dissolved phosphate microbes inoculation, rock phosphate mixing. At different composting phases, the samples were taken for the determination of phosphorus forms. Compared to CK, organic P, dissolved P and rapidly available P of CP increase by 2 049.8, 264.2, 954.0 mg/kg at final stage of composting, respectively; while that of CMP increase by 4 188.6, 648.7, 3 576.4 mg/kg, respectively. The increase of organic P, dissolved P and rapidly available P in CMP is 2.04, 2.46, 3.75 times as that of CP, respectively. The results indicated dissolved phosphate microbes inoculation composting with pre-mixing rock phosphate would accelerate transform efficiency of insoluble phosphate, increase the available P of compost production. |
