摘　　要：苏棉 13号是江苏沿江地区农科所于 1995年选育、1999年由江苏省农作物品种审定委员会审定定名的早熟棉新品种 ,尤其适合油菜或大元麦收获后移栽种植。 1998～ 2 0 0 0年 ,笔者对公顷总铃 12 0万个以上的高产典型进行了调查 ,从产量结构、单株结铃性状、成铃动态 3个方面 ,对苏棉 13号的单株成铃、果枝成铃、果节成铃、时间成铃和成铃强度、成铃高峰期、成铃率等 7个指标进行了分析 ,总结出了高效栽培技术 ,包括奠定高产生育基础、改善群体生长环境、合理肥料运筹等 3项主要措施。New cotton variety-Sumian No.13 with the character of early rnaturity was bred by Yangjiang Prefecture Agricultural Institute of Jiangsu province in 1995 and approved by Jiangsu Province Committee of Crop Approval in 1999. Sumian No.13 was suitable for planting after rapeseed or wheat harvesting. The plants growing in the field with 1.2 million bolls/hm 2 were investigated in the yielding components, the bolling character of single plant and the bolling dynamic and seven factors (the bolls per plant, bolls per branch, bolling time and density, maxium bolling period and bolling rate) were analyzed. The techniques with high efficiency including development base with high yield, the improvement of population growth environment and reasonable application of fertilizer were summrized.
