中文摘要:
      采用田间调查和实验室土壤分析方法,探讨了VT秸秆腐熟剂对怀集县秸秆腐解速度和土壤肥力的影响,以其更好地增加土壤肥力。结果表明,施用VT腐熟剂可以有效增加土壤的酸碱缓冲作用,加快秸秆腐解速度,提高土壤有机质含量。施用VT腐熟剂后,水稻秸秆的腐解程度在腐熟前期明显优于常规秸秆还田,有机质含量明显提升,有效磷含量明显下降,速效钾含量和缓效钾含量比对照明显上升,全磷含量和对照有显著差异,全钾含量比对照有所减少。
英文摘要:
      Using field survey and laboratory soil analysis, the effect of VT decomposing agent on straw decomposition rate and soil organic of Huaiji was studied, to improve soil organic content. The field experimental results showed that, after application of VT decomposing agent,straw decomposition level in the decomposing prophase was superior to conventional straw returning. Application of VT decomposing agent could effectively increase the cushioning effect of soil pH. The content of organic matter, available potassium and slow-available potassium were significantly increased than CK, but total potassium and available phosphorus content decreased compared with CK. There was significant difference in the total phosphorus content between application of VT decomposing agent and CK; VT decomposing agent could speed up the straw decomposing speed, improve soil organic matter content.
