摘　　要：以"北京新3号"大白菜为试材,在露地生产条件下,研究了两种聚合物包膜尿素(CRF-Ⅰ、CRF-Ⅱ)及硝化抑制剂结合尿素(DCD)对大白菜产量及品质的影响。结果表明,与习惯施肥(FP)相比,CRF-Ⅰ处理下大白菜产量提高了6.40%,CRF-Ⅱ、DCD处理下大白菜产量分别降低了1.48%、2.09%;CRF-Ⅰ、CRF-Ⅱ及DCD处理均能显著降低大白菜叶片中硝酸盐含量并提高VC、还原糖、粗纤维含量。Taking Chinese cabbage variety “Beijing New No.3” as material, the effects of coated control -release-urea and nitrification inhibitor on its yield and quality were studied under open -field condition.The results showed that, compared with conventional fertilization (FP), the self -made control -release-urea ( CRF-Ⅰ) could significantly increase the yield of Chinese cabbage by 6 .4%.The sold control-release-urea (CRF-Ⅱ) and nitrification inhibitor (DCD) decreased the yield of Chinese cabbage slightly by 1.48%and 2.09%respectively, and there was no significant difference .Compared with FP, CRF-Ⅰ、CRF-Ⅱand DCD could improve nutritional quality , such as the contents of vitamin C , amino acid , reductive sugar and crude protein , and decrease the nitrate content in Chinese cabbage leaves .
