以湘杂棉8号为试材，采用一基多喷、一基一追及当地常规施肥3种不同的施肥方式，比较司尔特棉花专用配方缓控释复合肥对不同收花期棉铃性状拉产量构成的影响。结果表明，各处理棉铃性状以一基一追处理最好，其次为一基多喷处理；不同施肥处理产量以一基一追处理的籽棉总产量最高，达3619.9 kg/hm2，籽棉产量比常规施肥高568.6 kg/hm2，增幅为15.71%，差异极显著。一基一追处理，即基施1500 kg/hm2专用缓控释肥，盛花期追施尿素117 kg/hm2+氯化钾90 kg/hm2+过磷酸钙192 kg/hm2，可解决棉花生长关键时期（花铃期）因天气干旱或雨涝难以追肥等问题，减少施肥次数，在节省施肥用工的同时达到增产增效的目的。

Cotton controlled-release compound fertilizers are of comprehensive reasonable proportion, which can realize synchronization betweenthefertilizernutrientreleaserateandcottongrowth,speeduplatergrowthstage,andincreaseinthenumberofflowersandbolls.At full-bloomstage, 117 kg urea/hm2 and 90 kg K CL/hm2 as topdressing can meet the nutrient demand of cotton growth, and solve the topdressing problemcaused by drought and water logging in the key period of cotton growth (flowering and boll setting stage). Cotton controlled-release compound fertilizers can reduce the number of fertilization, and achieve the purpose of increasing efficiency and saving fertilization employment.
