| 摘 要： | 试验在蒜套模式下对杂交抗虫棉品种鲁棉研15，设置了不同密度的对比栽培试验。结果发现，密度对棉花一生的影响，主要表现在花铃期，在高密度条件下，加强化控管理是夺取高产关键；密度与产量之间的变化符合二次曲线关系。密度较低时，棉花产量随着密度的增大而增加。高密度下随密度的增大而减少，蒜套杂交抗虫棉最佳种植密度为28500株/hm^2，籽棉平均产量最高约为5113．5kg／hm^2。

| Abstract: | garlic sets of test mode in the hybrid cotton varieties of Lumianyan 15, set up a comparison of different planting density trial. It was found that the density of the impact of life on the cotton, the main bell in the period spent in the high - density conditions, strengthen the control of high - yield management is the key to win; density and yield changes between the second curve in line with the relationship between the density is low, cotton production increased with increasing density, high -density increases with the density decrease in the best garlic sets of hybrid cotton planting density of 28 500 / hm^2, the highest average yield of seed cotton is about5 113.5 kg/hm^2. |
