摘　　要：[目的]筛选盐碱棉田改良剂的最优组合。[方法]采用4因素3水平正交试验设计,研究复合肥、腐殖酸、磷石膏、牛粪4种土壤改良剂对盐碱地棉花株高、果枝台数、成铃数及产量的影响。[结果]磷石膏对棉花产量影响最大;最优组合为复合肥450 kg/hm2、腐殖酸600 kg/hm2、磷石膏22 500 kg/hm2、牛粪7 500 kg/hm2,该处理的棉花株高中等,果枝台数、成铃数均为最高水平,籽棉产量最高,达到3 146.8 kg/hm2。[结论]为提高盐碱地棉花产量提供了技术支撑。[Objective]The aim was to select the optimal combinatiion of saline-alkali cotton. [Method]Using the orthogonal experiment design with four factors and three levels,effects of compound fertilizer,humic acid,phosphogypsum and cow dung on plant height,fruit-bearing branch number,number of bolls and yield of cotton were studied. [Result] The results showed that phosphogypsum was the most influential for cotton yield. The best ameliorant combinantion was compound fertilizer 450 kg / hm2,humic acid 600 kg/hm2,phosphogypsum22 500 kg / hm2,cow dung 7 500 kg/hm2. Under this treatment,cotton plant height was medium level,fruit-bearing branch number and number of bolls were the highest level,the seed cotton yield was 3 146. 8 kg / hm2. [Conclusion] The study can provide technical support for improving cotton yield in saline-alkali land.
