摘  要：
以夏季露地黄瓜为试材,采用田间小区试验与室内分析相结合的方法,研究了2种氮肥(颗粒尿素和尿素硝铵液态肥)不同用量对黄瓜产量和品质、肥料利用效率以及土壤养分变化的影响。结果表明:2种氮肥配合施用时,2个用量水平下黄瓜均增产显著,比单施等量单一氮肥更能促进产量的形成。尿素硝铵液态肥能提高黄瓜品质。氮源相同时,225 kg·hm~(-2)施氮水平下氮肥利用率高于300 kg·hm~(-2)水平处理。黄瓜收获后,土壤pH略有下降,土壤有效氮、有效磷和速效钾含量均有所提高。试验区露地种植黄瓜氮源以底肥150 kg·hm~(-2)尿素配合150 kg·hm~(-2)尿素硝铵液态氮肥作追肥效果最佳。该试验结果为黄瓜种植上氮肥配施用量及施用方法提供参考依据。

摘  要：
Taking summer cucumber as test material,field plot experiments and indoor analysis were conducted to study the effects of different amounts of two kinds of nitrogen fertilizers(granular urea and urea ammonium nitrate solution) on cucumber yield and quality,nitrogen use efficiency and soil effective nutrient changes.The results showed that the yield of cucumber increased significantly at the two N levels when the two kinds of nitrogen fertilizers applying in combination,which could promote the yield formation while applying alone at the same level of N.Urea ammonium nitrate liquid fertilizer could improve the quality of cucumber.Nitrogen use efficiency at 225 kg·hm~(-2) N level was slightly higher than 300 kg·hm~(-2) N level when nitrogen source was the same.The soil pH decreased slightly after planting cucumber using chemical fertilizers(nitrogen,phosphorus and potassium),while the contents of available nitrogen,available phosphorus and available potassium increased.The best effect of nitrogen for cucumber in open field was 150 kg·hm~(-2) urea as base fertilizer and 150 kg·hm~(-2) urea ammonium nitrate solution as top dressing.The results of the experiment would provide theoretical basis for the amount and method of nitrogen fertilizer on cucumber planting.
