| 摘 要： | 在河南省高产栽培条件下,研究了抗虫杂交棉豫杂35的适宜密度和行距配置。结果表明,在保留2~3个强势叶枝时,豫杂35以种植2.25万株/hm2配合行距1.20 m较为适宜,分别比1.50万株/hm2配合行距1.20 m、2.25万株/hm2配合行距1.00 m、1.50万株/hm2配合行距1.00 m、3.00万株/hm2配合行距1.20 m、3.00万株/hm2配合行距1.00 m的处理增产皮棉3.31%,4.42%,5.41%,8.63%,16.38%。增产的主要原因是棉花叶面积系数(LAI)适中,冠层光分布合理,干物质分配到生殖器官的比例较大,单位面积的总成铃数较高。

| Abstract: | Suitable densities and configurations of insect-resistant Bt transgenic hybrid cotton Yuza 35 was studied under high yield cultivation conditions in Henan province.Results showed that,in the cases of 2-3 predominant monopodium per plant was retained,population of 2.25×104 plant per ha with 1.20 m-wide rows was suitable for Yuza 35 and 3.31%,4.42%,5.41%,8.63%,16.38% more lint yield was harvested comparing with 1.50×104 plant per ha with 1.20m-wide rows,2.25×104 plant per ha with 1.00m-wide rows,1.50×104 plant per ha with 1.00m-wide rows,3.00×104 plant per ha with 1.20m-wide rows,3.00×104 plant per ha with 1.00m-wide rows respectively.Cotton population of 2.25×104 plant per ha with 1.20m-wide rows also showed appropriate LAI and light distribution in canopy,more dry matter distributed to reproductive organs and more bolls retained. |
