摘　　要：以天杂26号棉花品种为试材,在裸根苗移栽和穴盘苗移栽2种栽培方式下,研究了不同栽培密度对棉花第1-9节位叶枝长度、叶枝籽棉重量和叶枝数量的影响。结果表明：穴盘苗移栽棉和裸根苗移栽棉的单株叶枝籽棉重及有效叶枝数量均随栽培密度的增大而降低,其中穴盘苗移栽棉的降低幅度较大。The effects of different plant density on the length of leafy shoot at 1-9 node orders,the seed cotton weight of leafy shoot and the leafy shoot number of cotton variety Tianza No.26 were studied with the cultivation patterns of bare root seedling transplanting and plug seedling transplanting.The results showed that the seed cotton weight of leafy shoot per plant and effective leafy shoot number decreased with the increasing of plant density with two cultivation patterns,which decreased larger with plug seedling transplanting.
