| 摘 要： | 试验采用尼龙布袋埋袋法研究了5种单一物料(玉米秸、稻秸、苜蓿、鸡粪、猪粪)和2种混合物料(玉米秸-猪粪-鸡粪、苜蓿-猪粪-鸡粪)在潮土中的腐解状况,以了解土壤中有机质的积累规律,探讨有机肥料对土壤的培肥效果。研究结果表明,玉米秸、稻秸、苜蓿、鸡粪、猪粪等是增加土壤有机质的较好物料;对C/N比较高的物料,当增加N素(添加猪粪、鸡粪这些氮含量较高的物料)、调节C/N比值时,可以促进混合物料有机碳的分解和向腐殖质的转化。

| Abstract: | A nylon mesh bags method was conducted in aquic brown earth to study the decomposition and retention rate of organic material, with five single treatments (maize straw,rice straw,alfalfa,chook manure and pig manure) and two mixed treatments (maize-chicken manure-pig manure, alfalfa-chook manure-pig manure).The results showed that these five organic materials were very important to increase soil organic matter and cultivate soil fertility. The decomposition and humification ratio of the organic materials could be increased by adjusting its C/N ratio. |
