摘要
在盆栽条件下,研究了添加硝化抑制剂双氰胺、硝化抑制剂3,5-二甲基吡唑、硝化抑制剂双氰胺与脲酶抑制剂氢醌组合的尿素(D-U、DMP-U、H-D-U)对芹菜生长及硝酸盐含量等影响。结果表明,施用抑制剂尿素能提高芹菜的地上部干重及其占总生物量的比例,降低芹菜叶、茎中的硝酸盐含量,提高芹菜叶、茎中的维生素C、氨基酸和粗蛋白的含量。H-D-U对减少芹菜体内的硝酸盐累积具有最明显的效果。
With pot experiment,this paper studied the effects of urea amended with dicyandiamide(D-U),3,5-dimethylpyrazole(DMP-U),and dicyandiamide plus hydroquinone(H-D-U) on the growth of celery and its quality.The results showed that applying test urea fertilizers could enhance the aboveground biomass and its proportion to total biomass,decrease the nitrate content of leaf and stem,while increase their vitamin C,amino acid,and crude protein contents.H-D-U had the best effect in decreasing the nitrate accumulation i...
