| 摘 要： | 不同施肥途径对土壤有机质的影响各异,有机质总量比培肥前5年累积增长为:有机肥>秸秆还田>草木樨还田>化肥,对照区有所下降。重组有机质、复合有机质及复合体中不同结合态腐殖质也发生明显变化。有机物料培肥土壤是提高土壤肥力的重要途径。

| Abstract: | The effects of different fertilizing ways on soil organic matter were different. The increase of the total content of soil organic matter in five years before soil fertilizing was as follows: farm manure>crop straw left in soil>sweet clover left in soil>fertilizer, while in control plot the content went down. The contents of organic matter in heavy fraction, complex organic matter and differently combined humus in organo-mineral complexes changed markedly. Applying organic material to the soil is the important way to increase soil fertility. |
