| 摘 要： | 通过田间试验,研究了不同秸秆(水稻秸秆和玉米秸秆)不同量覆盖条件下早地油菜株高、花序数和分枝数的差异,以及0～10cm和10～20cm土层土壤有机质、全氮、碱解氮、全磷、有效磷、全钾、速效钾和pH的动态变化过程,并进行了产量分析.结果表明:秸秆覆盖处理下油菜株高高于对照,有速腐剂处理的株高最高;秸秆覆盖处理花序数多于对照;速腐剂处理下一级分枝数高于不加速腐剂处理;覆盖处理的有机质和碱解氮含量均略高于对照;加速腐剂覆盖处理的产量最高.

| Abstract: | A field trial was undertaken to investigate the performance of varying rice and corn mulch treatments with and without rottening agent on growth,yield and soil nutrients dynamics.The dynamic alteration in soil organic matter,total nitrogen,total phosphorus,alkali-hydro nitrogen,effective phosphorus,rapidly-available potassium and pH in 0~10cm 10~20cm soil layer were determined.The results revealed that rice and corn straw mulching improved the plant height over control but this improvement in plant height w... |
