| 摘 要： | 利用田间试验研究了硫加树脂包膜尿素对冬小麦最大分蘖数、叶片叶绿素、穗数、千粒重、产量、籽粒粗蛋白含量、肥料利用率的影响.结果表明,与施用普通尿素比较,控释期为4个月的硫加树脂包膜尿素在减少20%和40%用量且一次性作基肥施用情况下,冬小麦最大分蘖数、穗数、产量没有明显差别,而千粒重、籽粒粗蛋白含量和肥料利用率显著提高;研究还表明,硫加树脂包膜尿素一次性作基肥施用效果优于基肥和追肥分次施用. |

| Abstract: | This paper investigated effects of polymer/sulfur coated urea on number of tillering,proportion of chlorophyll,number of ears of grain,thousand-grain weight,yield,grain protein content and fertilizer use efficiency by field experiment.The results showed that comparison to normal urea,polymer/sulfur coated urea which was used as base fertilizer with a release period of four months could achieve same effects on number of tillering,number of grain ears and wheat yield with 20% and 40% less use level,while thou... |
