摘要
通过2011～2013年连续三年在江苏丰县棉花“万亩”高产创建区内进行了棉花高产和超高产栽培示范及产量形成因素的调查与分析，结果表明：形成超高产棉田的主要因素是光热资源丰富、株行距配置合理、品种的产量潜力大、肥水运筹与棉花生育协调性好；超高产棉田表现成铃多、成铃率高、成铃协调和棉株透光性好等特点。
From 201 1 to 201 3,the author carried on the . high yield and super high-yielding cultivation demonstration,in-vestigated and analyzed of the factors of yield formation for three consecutive years in”ten thousand mu”high-yielding cre-ating area in Fengxian of Jiangsu province . Results showed that：the main factors in the formation of super high-yielding cot-ton field were these,abundant light and heat resources,spacing reasonable,potential high-yielding variety,application of fertilizer and water was good coordination of cotton growth;characteristics of super high-yielding cotton field were boll num-ber,high rate of boll-setting,coordination and good light transmittance and so on .
