| 摘 要： | 经过12 a的不同施肥试验分析,秸秆还田和秸秆还田+NPK处理土壤密度比试验前下降0.34～0.37g/cm3,施栏肥和施栏肥+NPK处理土壤密度比试验前下降0.30～0.36 g/cm3。秸秆还田和秸秆还田+NPK处理田间持水率比试验前增加4.09%～5.01%,施栏肥和栏肥+NPK处理田间持水率比试验前增加3.26%～5.99%,单施NPK和对照处理田间持水率比试验前增加1.82%～2.15%。

| Abstract: | The consecutive 12 years of application different kinds of fertilizers greatly impacted the plain soil bulk density and the structure of water-stable aggregate.The treatments of return of rice stalk and return of rice stalk plus application of N,P and K fertilizer induced the decline of soil bulk density by 0.34~0.37 g/cm3 than before,and that of the treatments of application of manure and application of manure plus N,P and K fertilizer was 0.30~0.36 g/cm3.Otherwise,the treatments of return of rice stalk and return of rice stalk plus application of N,P and K fertilizer increased the field capacity than before by 4.09%~5.01%,the treatments of application of manure and application of manure plus N,P and K fertilizer was 3.26%~5.99%,and that of the treatments of application N,P and K fertilizer only and the control treatment was 1.82%~2.15%.All of these showed that the physical characters of soils. |
