| 摘 要： | 采用土培试验对含硝化抑制剂DMPP(3，4-二甲基吡唑磷酸盐)硫硝铵(ASN)氮肥(简称ASN DMPP)不同基追肥比例对小青菜硝酸盐累积及营养品质的影响进行了探讨．结果表明，等氮量(每千克土用0．5g氮)施用条件下基肥75％、追肥25％的基追肥比例不仅可提高蔬菜产量、降低硝酸盐含量，还可提高Vc、氨基酸、Zn、N、K含量，改善了蔬菜品质。

| Abstract: | Effects of different ratios of basal application to top dressing of ammonium sulphate nitrate (ASN) fertilizer with nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) (for short ASN+DMPP) on nitrate accumulation and nutritional quality of greengrocery (Brassica campestris L. ssp. chinensis) was investigated in pot experiment. Results showed that the ratio of basal application to top dressing of 75 to 25 in equal ASN+DMPP rate (1 kg soil 0.5 g N) could not only increase vegetable yield, decrease nitrate concentration,but also increase Vc, amino acid, Zn, N and K concentration, and hence improved vegetable nutritional quality. |
