在水肥条件和栽培技术措施基本一致的情况下,选择不同棉花品种进行分期打顶处理,进一步验证供试品种的丰产规律性,为棉花生产提供有价值的技术依据。因此,我们在2008-2010年在博尔塔拉蒙古自治州精河县、博乐市分别进行了此项试验,通过棉花不同时期打顶试验,进一步明确了博州棉花打顶最佳时期和棉花不同时期打顶对产量和各生育性状的影响。
Under the conditions of water and fertilizer and cultivation techniques are basically the same, choose different cotton varieties staged stope processing, to further validate the test varieties of high yield regularity, provide valuable technical basis for cotton production. Therefore, we carried out this experiment in Bole, Jinghe County, Bortala Mongol Autonomous Prefecture from 2008 to 2010 respectively. Through the cotton topping test at different periods, we further clarified that the optimal period for cotton toping in Bose and Cotton Effects of Topping on Yield and Fertility in Different Periods.
