| 摘 要： | 田间试验以中棉所41为材料,设置了6个密度处理,结果表明,蕾期和初花期低密度处理较高密度处理相对提前3～4 d,22.5万株/hm2密度处理的皮棉产量最高,达到2 778 kg/hm2,该群体从盛花期到吐絮期能维持较高的叶面积指教,其冠层总光吸收率均在89%以上,冠层上、中、下层平均光吸收率分别为75%、12%、7%,...

| Abstract: | The present investigation was undertaken in the field experiment in the South of Xinjiang to study the relationship between lint yield and leaf area index,canopy light absorption rate at different growth period in 6 various colony densities,which were 9,13.5,18,22.5,27,31.5 ten thousands plant/hm2 respectively.The cotton cultivar was Cotton Research Institute 41.The results revealed that the bud stage and the flowing stage of colonies under lower planting densities were earlier 3 to 4 days than that of colo... |
