施用不同有机物土壤有机质增加,不同有机物对土壤有机质的累积作用与有机物的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土壤供肥;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;连续向土壤施用有机物料,土壤腐殖质数量增加、品质改善,有利于土壤结构的改良,施用有机物养地、供肥能力的增强,对作物产量的增加起到良好的作用。
The application of different organic matter increased soil organic matter, organic matter accumulation of different organic matter and organic matter C / N value and chemical composition closely related; humification coefficient is conducive to soil fertility, decomposition rate is conducive to soil fertilization ; Soil respiration intensity and the decomposition rate of organic matter showed a consistent trend; the correlation between soil easy oxidation of organic matter and crop yield was better than that of soil organic matter; continuous application of organic material to the soil increased soil humus quality, quality improvement is conducive to soil structure improvement, The use of organic matter to raise fertility, enhance the capacity of crops to play a good role.
