| 摘 要： | 对福农15号、福农28号和福农39号等3个甘蔗品种在2种行距、3种群体密度下的农艺性状表现和冠层结构特点进行研究，以探明不同行距和群体密度对甘蔗生长的影响。结果表明，福农15号伸长前期长势稳健，中期快，后期慢，适于宽行稀植；福农39号伸长前期、中期长势稳健，后期持续伸长期最长，亦表现出宽行稀植的增产潜力。此外，针对上述品种特性提出了机械化栽培技术要点。 |

| Abstract: | The agronomic traits and canopy characteristics of sugarcane variety FN15, FN28 and FN39 under two line-width and three planting density were investigated. The results showed that both FN15 and FN39 were adapted to wider line and sparse planting. FN15 grew steadily in the earlier stage of elongation, quickly in the mid-term and slowly in the later stage. FN39 grew steadily in the earlier stage and the mid-term of elongation and sustained the longest later stage. From above, some technological points for those varieties in mechanized cultivation were proposed. |
