摘要: 在呼和浩特市开展设施黄瓜氮肥不同用量试验,研究氮肥对黄瓜产量以及体内硝酸盐和亚硝酸盐含量的影响,结果表明,氮肥用量125 kg/667m2对于提高黄瓜产量来说是一个最佳的氮肥施用量。在氮肥用量为50-100 kg/667m2时,氮肥用量与黄瓜硝酸盐及亚硝酸盐成正相关关系,在氮肥用量100-125 kg/667m2时,黄瓜硝酸盐和亚硝酸盐含量相对较低,是比较适宜的氮肥用量;在综合考虑经济合理产量和良好品质的同时,兼顾最大肥料利用率,减少环境污染,可以得到目标产量8 000 kg/667m2下,氮肥用量100-125 kg/667m2为设施栽培黄瓜最佳的合理施肥量。

Abstract: The nitrogen fertilizer experiment was carried out in Hohhot to study the influence of nitrogen fertilizer on cucumber yield and the content of nitrate and nitrite. The results showed that nitrogen application of 125 kg/667m2 was an optimum nitrogen for improving the cucumber yield. There was a positive correlation between the nitrogen fertilizer and nitrate or nitrite in cucumber when the dosage of urea were between 50 to 100 kg/667m2.The nitrate and nitrite were relatively lower when the dosage of urea were between 100 to 125 kg/667m2. In consideration of the economic production and good product quality and the largest fertilizer utilization, reduce environmental pollution. For getting the target yield by 8 000 kg/667m2,the dosage of urea between 100 to 125 kg/667m2 was the reasonable fertilizer application for greenhouse cucumber in Hohhot.
