摘　　要：以中熟品种苏棉４号为材料，研究麦后移栽棉不同长势棉株的不同花期棉铃各部分干物质积累与产量、晶质形成的关系。结果表明，健壮型棉铃内予棉干物质积累的速度最快；养分转化利用率最高；有利于产量和品质的形成。早衰型较差，贪青型居中。Su Mian No. 4 (medium mature varicty) was used as experimental material to study the relationshipbetween the accumulation of dry matter and the formation of lint yicld and quality at the differnt parts in bollsdeveloped at various blooming dates on variously vigorous cotton plants transplanted after wheat harvest. The resultswere as follows. The accumulation rate of dry matter in seed cotton of the sound type was fastest, and the rate oftransformation and consumption of nutrition of the sound type was highest. As mentioned above, it was bencfited to form lint yicld and quality. The premature senesencetype was the lowest, and the over growth type was medium.
