不同有机物料在土壤中的分解速率及腐殖化系数与有机物料的C/N值及化学组成分密切相关,腐殖化系数高的有利于土壤培肥,分解速率快的有利于供肥;土壤呼吸强度与有机物的分解速率表现一致趋势;土壤易氧化有机质与作物产量的相关性优于土壤有机质,用土壤易氧化有机质数量作为土壤肥力指标较土壤有机质更切合实际.连续向土壤施入有机物料,土壤腐殖质数量增加、品质改善,有利于土壤结构的改良,对增产、增收起到良好作用.
The decomposition rate and humification coefficient of different organic materials in soils are closely related to the C / N value and chemical composition of organic materials. High humification coefficient is beneficial to fertilizing soil and the decomposition rate is favorable for supplying fertilizer. Soil respiration intensity and decomposition rate of organic matter tended to be consistent with each other. The correlation between soil vulnerable organic matter and crop yield was better than that of soil organic matter. It was more practical to use soil organic matter as indicator of soil fertility than that of soil organic matter. Materials, soil humus quality increased, quality improvement, is conducive to the improvement of soil structure, to increase production, increase income play a good role.
