| 摘 要： | 研究了陕西关中主要蔬菜产区设施栽培蔬菜的硝酸盐累积现状,探讨了施氮量对蔬菜硝酸盐累积的影响。结果表明,宝鸡、杨凌、咸阳、西安四地的新鲜大棚蔬菜硝酸盐污染严重,部分对硝酸盐敏感的蔬菜如萝卜、芹菜等硝酸盐含量超过无公害蔬菜卫生限量标准。施氮对蔬菜硝酸盐累积量的影响显著,随施氮量的增加,蔬菜可食部分的硝酸盐含量增加。

| Abstract: | The status of nitrate accumulation in vegetables under protected cultivation in Shaanxi Guanzhong area was investigated. The effect of nitrogenous fertilizer's quantity on nitrate contents in vegetables' edible parts was discussed. Results were as follows: nitrate contamination in fresh vegetables' edible parts was very serious in Baoji, Yangling, Xianyang and Xi'an. Nitrate accumulation in some sensitive vegetables as radish, celery and others exceeded the standard value of contamination-free vegetables. The quantity of nitrogenous fertilizer's effect was notably, with its adding, the nitrate contents in vegetables increasing. |
