摘　　要：为考察在棉花生育期叶面喷施含腐殖酸水溶肥料的增产效果,开展了田间小区试验。试验设置了3个处理,分别为常规施肥、常规施肥+叶面喷施等量的清水、常规施肥+叶面喷施含腐殖酸水溶肥料,每个处理重复3次。结果表明:喷施含腐殖酸水溶肥料处理的单株结铃数增加0.6~0.7个,成铃率提高9.7%~9.8%,单铃质量增加0.3 g,衣分提高0.2%,籽棉增产率为23.0%~25.6%,投入产出比为1∶(7.9~8.7)。叶面喷施含腐殖酸水溶肥料可以显著提高棉花产量,具有明显的经济效益。In order to investigate the yield increasing effect of spraying humic acid containing water-soluble fertilizer on the leaves of cotton at the growth stage,a field plot experiment is carried out.Three treatments are being set up:conventional fertilization,conventional fertilization plus foliar spraying of equal amount of clear water,conventional fertilization plus foliar spraying of humic acid water-soluble fertilizer and each treatment is repeated for three times.The results show that the number of bolls per plant increased by 0.6-0.7,the boll rate increased by 9.7%-9.8%,the weight of single boll increased by 0.3 g,the lint content increased by 0.2%,the yield of seed cotton increased by 23.0%-25.6%and the input-output ratio is 1∶(7.9-8.7).Spraying water-soluble fertilizer containing humic acid on leaves can significantly improve cotton yield and show obvious economic benefits.
