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。
Sumian No. 13 was selected by the Institute of Agricultural Sciences in Jiangsu Province along the Yangtze River in 1995 and was accredited by the Crop Variety Approval Committee of Jiangsu Province in 1999 as a new precocious cotton variety. It is especially suitable for transplanting after harvest of rape or Danyuan Mai. From 1998 to 2000, the author conducted a survey of more than 120000 high-yield typical bolls of hectare. From three aspects of yield structure, boll bolling per plant and boll-forming dynamics, Such as boll, fruiting branches, bolls, time bolls and bolls, boll timing, boll rate and other seven indicators were analyzed, and efficient cultivation techniques were summarized, including laying a foundation for high yield fertility, improving Population growth environment, rational fertilizer operation and other three major measures.
