摘要: 采用田间试验和实验室分析方法研究了滴灌马铃薯施用尿素硝酸铵溶液(UAN)的施肥肥效,研究结果表明,马铃薯施用氮磷钾肥均有显著的增产效果,施用氮、磷、钾肥分别增产23.5%、18.3%和14.8%。马铃薯施用氮、磷、钾肥的农学效率分别为23.0,34.9,23.5 kg/kg。施用氮、磷、钾肥均显著提高马铃薯的单薯重和商品薯率。滴灌马铃薯施用氮、磷、钾肥的肥料利用率分别为46.0%、15.9%和53.7%。马铃薯施用氮肥块茎的淀粉含量均有所降低,平均降低1.04个百分点。施用尿素硝酸铵溶液和施用尿素处理马铃薯的淀粉含量没有差异。

Abstract: It was researched that the fertilizer effect of drip irrigation potato was applied urea ammonium nitrate solution(UAN)by the method of field experiment and laboratory analysis.Results indicated that:Yield of potato was increased significantly by applying NPK fertilizer,increased by 23.5%,18.3%,and 14.8%,respectively.Fertilization utilization efficiency of N,P,K were 46.0%,15.9%,53.7% on potato,respectively.Per tuber weight,rate of commodity and fertilize utilization were increased significantly by applying NPK fertilizer.Potato tuber starch content was decreased 1.04 percent point by applying nitrogen fertilizer,however,it was not influenced by application of UAN and urea treatment.
