江淮地区实施夏收油菜或大麦后移栽双秆棉栽培方式 ,实现伏桃和早秋桃皮棉 1 5 0 0 kg· hm-2的优质高效栽培目标。双秆棉开花结铃期 40天左右 ,大田生长期 1 40天左右 ,分别较麦套移栽棉缩短 30～ 40天。在 5 .2 5万株·hm-2适宜密度下选用抗虫杂交棉、加大前期施氮比重 ,即安家肥与花铃肥比例 2∶ 2或 3∶ 1、两步化调等关键技术 ,为大幅度提高植棉经济收益、优质高效和生态环境改善、向机械化植棉过渡提供了新途径
The implementation of transplanting double-stalk cotton cultivation method after summer rape or barley in Jianghuai region achieves the goal of high-quality and high-efficiency cultivation of peach and early peach peach cotton 1 500 kg · hm-2. Double stalk cotton flowering period of about 40 days, about 40 days of field growth, respectively, than wheat transplanting cotton shortened 30 to 40 days. Insect-resistant hybrid cotton was selected at a suitable density of 52 500 plants · hm-2, and the proportion of nitrogen fertilizer in the early stage was increased, that is, the ratio of 2: 2 or 3: , In order to greatly improve the economic benefits of cotton, high quality and efficiency and improve the ecological environment, to provide a new way for mechanized cotton transplanting
