| 摘 要： | 在田间小区实验下,通过水杨酸比色法研究不同氮肥用量、不同磷肥用量对黄瓜体内硝酸盐含量的影响.结果表明:黄瓜体内硝酸盐含量随氮肥用量的增加而增加.第1次采样施肥后,每隔7d采1次样,第3次采样时黄瓜体内硝酸盐含量最高,之后又随时间的推移而下降.最佳氮磷配施用量(氮为375kg/hm2,磷为75k/hm2),此施肥量下黄瓜产量最高,并且硝酸盐累积量不超标.

| Abstract: | Effects of different applying quantity of Nitrogen fertilizer and Phosphorus fertilizer on condition of field experiment.The results show:Nitrate content of Huang-gua increases with Nitrogen fertilizer applied quantity improved,The Nitrate content of Huang-gua is the highest at the forteenth day,and afterwards reduced.The best proportion of applying of Nitrogen fertilizer and Phosphorus is 375kg/hm2(Nitrogen fertilizer)and 75kg/hm2(Phosphorus fetilizer),nitrate content of Huang-gua don't surpass the standard,and the yield is the highest. |
