中文摘要:
      为了提高氮肥利用效率,减少因过量施氮对环境造成的危害,以河南温县和许昌为试验地点,对添加不同浓度的脲酶抑制剂在小麦上的应用效果作以比较,结果表明:(1)不同浓度的脲酶抑制剂在拔节、开花期对冬小麦群体动态和干物质累积的影响较大,以加0.12%脲酶抑制剂效果较好。(2)加0.12%脲酶抑制剂处理高于其他处理产量,可提高单位面积穗数与籽粒千粒重。(3)加脲酶抑制剂处理氮肥当季利用率、氮因子生产力、氮肥农艺效率都高于习惯施氮,都以加0.12%脲酶抑制剂处理最高。
英文摘要:
      In order to guarantee the high yield of grain and improve the nitrogenous fertilizer utilization efficiency,an experiment was conducted in Wenxian and Xuchang of Henan province to compare the effects of nitrogenous fertilizer with different concentration of urease inhibitor on wheat.The results showed:(1) The great effects on groups developments and dry matter accumulation was in jointing stage and anthesis,with 0.12% urea\|urease inhibitor was the best.(2) Urea with 0.12% urease inhibitor made the highest yield,and improved the number of ear of wheat and the weight of the seeds.(3) Urea with urease inhibitor get higher RE,PFP and AE than conventional urea use,and urea with 0.12% urease inhibitor made the highest.
