摘  要：
[目的]筛选适合黑龙江春玉米田的肥料增效剂。[方法]研究添加不同配比长效复合增效剂、脲酶抑制剂氢醌、硝化抑制剂双氰胺、复硝酚钠、DA-6胺鲜酯肥料增效剂对春玉米产量、叶绿素含量、叶面积指数及氮肥利用率的影响。[结果]施用肥料增效剂处理比常规处理产量均有所增加,提高了8.3%～25.2%;最佳肥料增效剂是硝化抑制剂双氰胺添加量为肥料总重的0.6%、长效复合增效剂添加量为肥料总重的0.3%;施用肥料增效剂处理玉米植株叶绿素含量、叶面积指数、农艺性状及产量均有所提高;施用肥料增效剂氮肥利用率提高了5.63～25.73百分点;氮农学效率提高了4.73～14.43 kg/kg;氮肥贡献率提高了5.43～14.34百分点。[结论]硝化抑制剂双氰胺、长效复合增效剂为黑龙江春玉米田最适合的肥料增效剂。

摘  要：
[Objective]To select fertilizer synergists suitable for spring maize field in Heilongjiang Province. [Method]The effects of long-acting compound synergists,urease inhibitor hydroquinone,nitration inhibitor dicyandiamide,sodium nitrophenol,DA-6 amine fresh ester fertilizer synergists on yield,chlorophyll content,leaf area index and nitrogen use efficiency of spring maize were studied. [Result] Compared with the conventional treatment,the yield of fertilizer synergist treatment increased by 8.3%-25.2%.The optimum fertilizer synergist was 0.6% of the total fertilizer weight and 0.3% of the total fertilizer weight. The chlorophyll content,leaf area index and agronomic traits affecting yield were all increased by applying fertilizer synergist. The application of fertilizer synergist increased the utilization rate of nitrogen fertilizer by 5.63-25.73 percentage point,the agronomic efficiency of nitrogen increased by 4.73-14.43 kg/kg,and the contribution rate of nitrogen fertilizer increased by5.43-14.34 percentage point. [Conclusion]Nitrification inhibitor dicyandiamide and long-acting compound synergist were the two most suitable fertilizer synergists for spring maize field in Heilongjiang Province.
