应用作物源库理论,研究北疆高产棉花的生育规律及生理指标,初步结果表明,高产棉花的生育进程必须适应北疆作物生长季节气温两头低中间高的特点,使结铃盛期与当地光温水最佳时段高度吻合。增加棉花群体冠层形成初期的叶面积指数(LAI),盛铃期LAI在3.23~4,协调了源库关系,加快了高能期储积产品器官干物质积累速度,延长了积累天数,提高了经济系数,盛铃期为48.58%~57.47%,控制适宜果节数为94.7~105.5个/m2叶,增加了单位叶面积的载铃量、生殖器官干重,分别为27.38~32.03个/m2叶、0.1637~0.2303kg/m2叶,叶铃比2.5~3∶1。这是衡量棉花源库协调的重要生理指标
The crop yield and sink theory was applied to study the fertility and physiological indices of high-yielding cotton in northern Xinjiang. The preliminary results showed that the growth of high-yielding cotton must adapt to the characteristics of low mid-height and high temperature of crop growth in northern Xinjiang, The best time for warm water is highly consistent. LAI increased at the early stage of canopy formation, and the LAI in Shengling stage was 3.23 ~ 4, which coordinated the relationship between source and sink, accelerated the accumulation of organ dry matter in high-energy storage products, prolonged the accumulation days and increased The economic coefficient was 48.58% ~ 57.47% in the boll stage and 94.7 ~ 105.5 / m2 leaves in the control, which increased the amount of bolls per leaf area and the dry weight of the reproductive organs , Respectively, from 27.38 to 32.03 leaves / m2 leaf, from 0.1637 to 0.2303 kg / m2 leaf and boll ratio of 2.5 to 3:1. This is a measure of cotton source library coordination of important physiological indicators
