| 摘 要： | 试验研究了氮磷钾肥配用以及化学氮肥与有机肥或硝化抑制剂配用对油菜硝酸盐积累的影响。结果表明 ,氮肥是提高油菜产量和增加硝酸盐积累的主要肥料品种。在施氮的基础上 ,配合施用磷钾肥有利于提高油菜产量和降低硝酸盐含量。不施氮肥 ,单施磷肥或钾肥均能增加油菜产量和硝酸盐积累。化学氮与有机氮各半 ,或在氮肥中加入硝化抑制剂 (DCD) ,既能提高油菜产量 ,又能降低硝酸盐积累

Effect of fertilizer application on nitrateaccumulation in rape |
| |
| Abstract: | Study on the effect of fertilizer application on nitrate accumulation in rape showed that nitrogen fertilizer was the major fertilizer in increasing yield and promoting nitrate accumulation in rape The corporation of nitrogen fertilizer with phosphate and pattasium fertilizers was available to raise yield and drop nitrate content in rape Without nitrogen application, phosphate or pattasium could increase yield and nitrate content The combination of half nitrogen coming from chemical and the other half from organic matter, or adding 10% of nitrification inhibitor(DCD)in nitrogen fertilizer was able to increase yield and decrease nitrate accumulation |
