| 摘 要： | 2008~2010年连续3年设12 000、21 000、30 000、39 000、48 000、57 000株/hm26个处理,在赣北中等肥力沙壤土上,进行合理密植技术及机理比较试验,结果表明:不同密度处理对棉花的生育进程、农艺性状、棉株叶面积、单株干物质积累与分配、冠层内温度与湿度、群体光透射率、成铃分布、纤维品质以及产量与经济效益等方面均有差异变化;根据试验结果和结合生产实践认为环鄱阳湖棉区中等肥力沙壤土湘杂棉8号的适宜种植密度为30 000~39 000株/hm2,实际种植密度可根据上述密度按照品种株型松散宜稀、紧凑宜密和肥力好宜稀、肥力差宜密的原则适当增减,以获得最佳产量和最佳经济效益,达到高产稳产的目的。

| Abstract: | From 2008 to 2010,6 treatments were designed 12 thousands per hm2,21 thousands per hm2,30 thousands per hm2,39 thousands per hm2,48thousands per hm2,57thousands per hm2,the results show that different densities have influence on growing process,agronomic characters,cotton's leaf area,dry material accumulation and distribution,temperature and humidity in Canopy structure,distribution of boll-setting,fiber quality,yield and economic efficiency.The Suitable density of Xiangzamian NO.8 is 30~39 thousands per hm... |
