【摘要】 旱地和水田施用新型N肥试验结果表明,与普通尿素相比,施用腐殖酸尿素、木质素尿素和涂层尿素对水稻、小麦均具有明显增产效果,稻谷增产率为14％～16％,小麦籽实增产率为4％～17％,肥效为腐殖酸尿素≥木质素尿素>涂层尿素。水稻对肥料N素利用率提高7％,差异达显著水平,小麦对肥料N素利用率提高2.7％～17％。更多还原

【Abstract】 The experiments of new-type N-fertilizers were carried out in paddy field and upland field. Compared with common urea,after humic acid-urea,lignin-urea and coating-urea were applicated,the output of paddy rice and wheat were oboviously increased. The yield of rough rice was increased by 14%- 16%,and the yield of wheat grain was increased by 4%-17%,the order of fertilizers efficiency was humic acid-urea≥lignin-urea>coating-urea. Apparent efficiency of nitrogen was also increased by 7% in paddy rice and increased by 2. 7% -17% in wheat.更多还原
