| 摘 要： | 以农家肥、化肥、秸秆、绿肥等培肥物质为试验因素,研究长期定位试验耗竭阶段土壤有机质的持续效应。4年耗竭试验结果表明,各处理土壤有机质含量皆呈现明显下降趋势。其中,农家肥、秸秆、化肥三种肥料的持续效应的大小顺序依次是:农家肥>秸秆>化肥。玉米连作不施肥区下降幅度不明显。绿肥—玉米轮作区变化有起伏;休闲区缓慢下降。从每两个培肥物质的交互作用对土壤有机质的影响来看,农家肥和秸秆、化肥和秸秆之间有明显的正交互作用,而农家肥和化肥之间交互作用不明显。

| Abstract: | A long-term fertilizing location test was carried out with farm manure,chemical fertilizer,straw and green manure from 1986 to 1996 in black soil.The sustainable effect of different fertilizing matters on soil fertility in exhausted stage was observed.During four years' experiment,it has been proved that the content of soil organic matter was degrading in all soil fertilizing treatments.According to the test,farm manure was the best for increasing the con- tent of soil organic matter,straw was the second an... |
