| 摘 要： | 通过盆栽和田间试验研究了固体和液体调节剂对大白菜硝酸盐含量和产量的影响。结果表明，固体调节剂对大白菜硝酸盐含量有明显的降低作用，幅度在 30％左右，基本消除大白菜硝酸盐污染，同时明显提高大白菜的产量。液体调节剂对大白菜硝酸盐含量影响不一，且幅度较小。

| Abstract: | Effects of solid and liquid N－ regulators on nitrate content and yield of Chinese cabbage were investigated by pot and filed experiments, respectively. The results showed that nitrate content was reduced by 30％ and the yield greatly increased by applying solid N－ regulator, making it possible to alleviate nitrate pollution. However, the effect of liquid N－ regulators on the nitrate content was not very significant. And different liquid N－ regulators had different effects on nitrate contents in Chinese cabbage. |
