| 摘 要： | 通过对南疆皮棉产量3000kg/hm2的超高产田进行研究,得出超高产棉株生长稳健矮壮,成铃数多,单株成铃5~7个,成铃率高,单铃重5.5g,衣分达42%;总干物质积累14223~22056kg/hm2,吐絮期比一般高产棉花铃重占干物质总重的比值高;叶面积指数最大为3.99,出现盛铃初期到盛铃期之间且维持时间长。

| Abstract: | The lint with 3 000 kg/hm2 of hybrid cotton in the south of Xinjiang was studied.The results indicated that the high-yielding cotton in the test field grew strongly with great number of boll,5-7 bolls per plant,5.5 g weight per boll,42% gining outturn,the total dry matter accumulation 14 223-22 056 kg/hm2.The maximum index of leaf area was 3.99. |
