摘要： 为了建立安徽沿江棉区机采棉种植模式,采用正交设计3套3因素3水平田间试验,研究了安徽沿江棉区机采棉优化栽培技术。结果表明,对安徽沿江棉区机采棉产量影响显著的栽培因子有品种、播期和种植密度等,DPC、N和去蕾措施等3个栽培因子对机采棉产量有不同程度的影响。综合考虑,将安徽沿江棉区机采棉栽培技术优化为：品种选用中棉所50、机收50等早熟品种,于5月下旬直播,播种密度为10.50～11.25万株/hm2,N用量为180 kg/hm2左右,DPC用量为180～270 kg/hm2,施肥和化控的具体方法要结合地力、长势、天气等因素综合考虑,条件允许时可以适当去除早蕾或晚蕾以促使机采棉成铃更为集中。

Abstract: Based on field experiments of multi-factor orthogonal designed, machine picked cottonScultivation techniquesSwere studied in the area along the Yangtze RiverSin Anhui Province, in order toSestablish the mode ofSmachine picked cottonScultivation techniquesSin the area. The results show that varieties, sowing date and planting density influence the lint yield of machine picked cotton along the Yangtze River significantly, and DPC,SN andSsquare removalSmeasures influence the lint yieldSto varying degrees. Machine picked cottonScultivation techniquesSwere optimized in the area along the Yangtze RiverSin Anhui Province, which includes that selecting of early maturing varieties, such as Zhongmiansuo 50 and Jishou 50, direct seeding in late May, with planting density ranging from 105 000 to 112 500 plants per ha, the content of N about 180 kg/ha, the content of DPC ranging from 180 to 270 g/ha. The specificSmethods of fertilization andSchemical controlSshould consider many factors,Ssuch as soil, growth, weather, etc. If possible, the early or late buds can be removed, in order to shorten the boll opening stage of machine picked cotton, which can be more easily mechanized harvesting of cotton once.
