北疆地区是新疆重要的植棉区,棉花早熟性是决定北疆棉花夺取丰产稳产的关键性因素。目前,北疆地区棉花品种多、乱、杂,主要原因是种子管理力度不够,乱引、乱调,不遵循品种试验、示范、推广程序,在引种鉴定、试验、示范上缺乏统一管理。为了验证自育的棉花品种(系)在沙湾县种植表现,新疆农业科学院经济作物研究所在沙湾县四道河子镇进行品种比较试验,旨在为该单位开展育种工作,和为本地区选择棉花品种提供参考。
The northern region is an important cotton-growing area in Xinjiang. Cotton precocity is the key factor that determines the cotton yield in northern Xinjiang is high and stable. At present, there are many varieties, chaos and miscellaneous varieties of cotton in northern Xinjiang. The main reason is that the management of seeds is not enough, chaotic and disorderly, and does not follow the varieties test, demonstration and popularization procedures. There is a lack of unified management on the introduction and appraisal, experiment and demonstration. In order to verify the performance of self-raised cotton cultivars (lines) in Shawan County, the Institute of Economic Crops of Xinjiang Academy of Agricultural Sciences conducted a comparative trial of cultivars in Si Dahezi Town, Shawan County, aiming to carry out breeding work for this unit and Regional selection of cotton varieties for reference.
