中文摘要在 15 a长期定位试验基础上研究了黄土高原旱地长期施用不同用量和配比的氮、磷肥对土壤剖面中硝态氮分布和累积的影响。结果表明:长期大量施用氮肥,在土壤剖面 100~180 cm之间形成硝态氮累积层,峰值出现在 140 cm处,最大值为 67.92mg/kg(单施 N 180 kg/hm~2); 配合施用磷肥可以降低土壤剖面硝态氮质量分数,根据试验,提出了旱地合理施肥的氮磷肥用量。
英文摘要Effects of application of N and P on distribution and accumulation of NO_3-N in soil profile were studied according to the basis of a 15-year located experiment. The results show that NO_3-N would be accumulated in 100~180 cm of soil profile under the condition that lots of N was applied for long time. And application of P would reduced this accumulation. The N and P quantity of reasonable fertilization was advanced according to the test.
