| 摘 要： | 通过大田试验探索不同灌溉模式下氮肥分次施用对稻田氮磷径流流失的影响.结果表明,传统灌溉条件下,不同施肥处理总氦、总磷流失量分别约为4.4l～17.85 kg/hm2和0.28～0.44 kg/hm2,其氮、磷流失率分别为3.2%和0.17%.相对于传统灌溉,间歇灌溉模式下的氮、磷流失量分别降低了约22.99%和10.01%,其氮肥流失率降低了1%,磷肥流失率与其大致相当.通过研究得出,间歇灌溉各施肥处理下小区产量较传统灌溉的平均增产约7.35%.在间歇灌溉条件下氮肥分四次施用处理下的径流氮、磷流失量相对较低,且增产效果明显.

| Abstract: | The article explored the influence of nitrogen fertilizer application with several times under different irrigation modes on nitrogen and phosphorus loss in paddy fields under field experiment condition.The results indicated that the runoff of total nitrogen and phosphorus was between 4.41~17.85 kg/hm2 and 0.28~0.44 kg/hm2 under different fertilizer treatments with traditional irrigation respectively.The loss percentage of nitrogen and phosphorus fertilizer was respectively about 3.2% and 0.17%.Compared to ... |
