利用新肥料，构建高效、简便的施肥管理措施，对于提高棉花生产的生态和经济效益具有重要的现实意义。该文采用田间试验方法，研究了基施涂层缓释肥与叶面施肥相结合，不同用量基施缓释肥与花期追肥氮肥相结合的不同管理措施对棉花结铃数、单铃重和产量的影响。结果表明，当地农民习惯施肥没有增产效果；基施涂层缓释肥，花期追施尿素增产效果显著，以基施1.2t/hm2涂层缓释肥，花期追施尿素187.5kg/hm2单产最高，较不施肥增产39%；叶面喷施氨基酸水溶性肥料没有显著增产效果。

To improve chemical fertilizer management in cotton cultivation is of significance for high ecologi?cal and economic benefit. Plots scale experiment with 11 treatments was executed and the results showed that local conventional fertilizer management had no effect on increasing cotton yield;slow releasing fertiliz?ers as base dose and urea topdressing at flowering and boll forming significantly increased the average bolls per area,the average weight per boll and the cotton yield per area. The yield increased at 39%when slow releasing fertilizers as base dose at 1.2t/hm2 and topdressing urea at N187.5kg/hm2. No signifi?cant effect was observed for cotton cultivation to spray amino acid water soluble fertilizer at the periods of flowering and boll forming.
