| Abstract: | The transplanted cotton following rape harvest is a main crop pattern of cotton cultivation in the Yangtze River Valley. This planting pattern has the advantage of higher land use percentage and labour productivity compared to the pre-vailing cropping patterns. Qwing to the limited growth period,cotton yield and fiber quality usually decrease to a certain ex-tent. In 2012-2013,the bolls flowering at Jul.5,Jul.15,Jul.25,Aug.5,Aug.15,Aug.25 and Sep.5 were analyzed for their quality characters. The result showed that the best boll setting period was from Aug.15 to Aug.25. In this period,the boll's charac-ters,such as the boll setting percentage, boll weight and lint percentage were higher,and the non pregnant seed rate was lower. The fiber quality was also better and suitable for spinning medium count yarn,with detailed value of fiber length 28 mm,specific strength 26 cN/tex, Mic value 5 and spinning consistence index 130. |
