采用 熟性不同 的３ 个陆 地棉 品种 ，在 肥水 充 足的 生 长条 件下 ，研 究了 棉 株不 同载 铃 量对其主要 生育性状 的影响 。结果表 明， 棉株 载铃 量 对株 高、果枝 总长 、果 节总 数均 有 极强 的 影响 ，其影响强 度随载 铃量的增 加而增加 ，累积 影 响量 随棉 株 生长 发 育时 间的 延 长而 增大 ；但 棉株 载 铃量对主茎 节数、果 节平均长 度影响 不显 著。 由此 分析 了 蕾铃 脱 落和 棉株 旺 长之 间的 关 系，以 及 棉株在一定 地力条 件下适宜 的单株载 铃量。
Using three different cultivars of upland cotton, the effects of different bolls of cotton plants on their main reproductive traits were studied under sufficient water and fertilizer conditions. The results showed that the boll weight of cotton plants had a very strong effect on plant height, fruit branch length and the total number of fruit nodes, and the impact strength increased with the increase of boll weight. The cumulative effect amount increased with the growth of cotton plants However, the boll weight of cotton had no significant effect on the number of main stems and the average length of fruit nodes. The relationship between the shedding of buds and the growth of cotton plants was analyzed, and the suitable boll weight of cotton plants under certain conditions of soil fertility was analyzed.
