| 摘 要： | 在北疆气候生态条件下,以杂交棉品种新陆早43号和鲁棉研24号为材料,采用育苗移栽稀植,研究杂交棉稀植条件下冠层结构、光合特性及与产量的关系.结果表明:与直播棉相比,移栽稀植条件下叶面积指数较低、冠层开度和透光率偏高,群体漏光损失严重,群体光合速率和干物质质量显著降低,但叶枝成铃的比例显著增加,且棉株生育进程有所提前,霜...

| Abstract: | Selected two hybrid cotton cultivars(Xinluzao 43 and Lumianyan 24) as experimental materials,canopy architecture and its correlation with yield characteristics of transplanted hybrid cotton at low planting densities were studied in North of Xinjiang.The results showed that compared with direct-seeded cultivation,transplanted hybrid cotton at low planting densities had decreased leaf area index and canopy photosynthetic rate and dry-matter accumulation,but increased canopy openness and light transmittance ra... |
