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。
In this experiment, five kinds of single materials (corn stalks, rice straw, alfalfa, chicken manure and pig manure) and two kinds of mixed materials (corn stalks - pig manure - chicken manure, alfalfa - pig manure - chicken manure ) Decomposing condition in the soils to understand the accumulation of organic matter in the soil and to explore the effect of organic fertilizers on soil fertility. The results showed that corn stalks, rice straw, alfalfa, chicken manure and pig manure were the better materials to increase soil organic matter. For those with higher C / N ratio, Higher material), adjusting the C / N ratio can promote the decomposition of organic carbon and the conversion to humus in the mixed material.
