| 摘 要： | 通过对北疆棉花主栽品种中棉36号,在三种不同打顶条件下,群体冠层结构的源库分布特点的分析。结果表明,在相同的管理水平下,此品种在2×104株/667m2经打顶处理2次的条件下群体光合速率达到峰值后下降缓慢,仍具有较强的光合能力;在盛铃期生殖器官干重较其他都高,通风透光良好;叶片叶面积指数适中有利于干物质积累和分配,此处理产量较其他处理都高。 |
| 关 键 词： | 棉花 打顶处理 切片 干物质 叶面积 源库 |

| Abstract: | The experiment began with the analysis of one variety of cotton by topping treatment to provide basis for reasonable distribution of source storehouse.The leading variety of cotton in the north Xinjiang was analyzed.The experiment results were as following:The photosynthetie rate of population reached the peak value,then slowly was decreased when the variety at 2×10~4 plants/667m~2 was treated with topping twice and it had still stronger photosynthetic ability;It's loin's dry weight,which had good ventilation and photopermeability,was higher than others at blooming stage;There was moderate index on the leaf surface which was available for accumulation and distribution of dry material.The yield with the treat-ment was higher than others with different treatment. |
| Keywords: | cotton topping treatment section dry materials area of leaf source storehouse |
