| 摘 要： | 研究了油-稻-稻种植模式下氮肥的后效应作用.结果表明,氮肥的施用对当季油菜生长的影响作用显著,油菜生长期间施用的氮肥对下季早稻的后效作用非常明显,但后效作用不长,对晚稻的生长已无促进作用.早稻生长期间施用的氮肥对下季的晚稻生长有一定的后效作用.因此,施用了氮肥的油莱田种植早稻可以减少氮肥的施用量;施用了氮肥的早稻田种植晚稻也可以适当减少氮肥的施用量.

| Abstract: | In order to study the residual effect of nitrogen in flow aquic paddy soil,a field experiment was carried out in planting mode of rape-early season rice-late season rice.The results showed that rape growth was significantly influenced by pplication of nitrogen fertilizer.The early-season rice growth was significantly influenced by aplication of nitrogen during rape growth,but residual effect of nitrogen during rape growth on late-season rice was not obvious.The late-season rice growth was influenced by application of nitrogen during early-season rice growth.Therefore,early-season rice could reduce application of nitrogen after planting rape and late-season rice could reduce application of nitrogen after planting early-season rice. |
