| 摘 要： | 为探讨菌渣还田对土壤肥力的影响,在大田试验条件下,研究不同菌渣(F)与化肥(C)配施对水稻生育期内土壤养分含量动态变化的影响。结果表明:在水稻的整个生育期内,菌渣与化肥配施能够明显提高土壤有机质、碱解氮、有效磷和速效钾含量,其中处理C100F100对土壤有机质的积累、提高土壤有效磷和速效钾水平作用最强,处理C100F50次之;处理C100F50提高土壤碱解氮的能力最大。综合考虑,在本试验条件下,处理C100F50可维持较高的土壤肥力,节约化肥施用及降低成本,实现废弃菌渣还田资源化合理利用。

| Abstract: | In order to investigate the effect of edible fungus residue on soil fertility,dynamic changes of soil nutrients contents during rice growth were monitored in a field experiment.Results showed that application of edible fungus residue(F) in combination with chemical fertilizers(C) could increase soil organic matter(SOM) content,available phosphorus(SAP) and available potassium(SAK),among which,the C100F100 treatment gained the highest SOM content,SAP and SAK,while the C100F50 treatment gained the highest available nitrogen.Based on this experiment conditions,C100F50 treatment could be a cost effective method to reduce the application rate of chemical fertilizers as well as to recycle the use of the edible fungus residue. |
