Abstract:
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.
