棉花杂种优势的利用以其高产、优质和较高的经济效益越来越多地得到了人们的重视.据有关专家认为:今后棉花生产发展的重要途径将是杂种优势的利用.为尽快推广应用杂交棉新技术,94年在兵团科委和石河子科委的支持下,立项继续研究,在石河子一三二团场开展了杂交棉的大田生产示范试验.经过课题组人员的努力,已完成了本年度试验.一、材料与方法参试材料5个,“102”F1、“128”F1、“102”F2、“128”F2和对照(新陆早1号原种).本试验随机排列三次重复.平均行距48.5厘米,株距13厘米,小区长28.5米、宽7.8米,面积222.3m~2.试验面积5亩,每处理面积1亩.理论密度10519株/亩.拾花三次,以小区霜前皮棉计产.
With its high yield, high quality and high economic benefit, more and more attention has been paid to the utilization of cotton heterosis.According to relevant experts, the important way for the development of cotton production in the future will be the utilization of heterosis.To promote the application as soon as possible Hybrid cotton new technology, 94 years in Corps Science Commission and Shihezi Science and Technology Commission, with the support of the project to continue research, Shihezi one or two field field carried out hybrid cotton field production demonstration test.After the task force’s efforts have been completed This year’s test.Material and methodTest materials 5, “102” F1, “128” F1, “102” F2, “128” F2 and control (Xinluzao No.1) .This experiment randomly arranged three times The average row spacing 48.5 cm, spacing 13 cm, cell length 28.5 m, width 7.8 m, an area of 222.3m ~ 2. The test area of 5 acres, each treatment area of 1 mu. Theoretical density of 10519 plants / Pre-frost lint production.
