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，将结铃盛期与当地光、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；协调源库关系，高能期加快储积产品器官干物质积累速度，延长积累天数，提高经济系数，盛铃期为48．58％～57．47％；控制适宜果节数为94．7～105．5个m-2叶，增加单位叶面积的载铃量，生殖器官干重，分别为27．38～32．03个·m－2叶、0．1637～0．2303kg·m-2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 study of fertility and physiology of high-yielding cotton in north Xinjiang using crop-derived pool theory showed that the fertility of high-yielding cotton had to adapt to the characteristics of low mid-height and high temperature during the growing season in northern Xinjiang. , Temperature and water were in good agreement with each other, increasing the leaf area index (LAI) in the early stage of canopy formation in cotton. LAI of Shengling boll stage was 3.23 ~ 4; coordination of source-sink relationship and high energy period accelerated the accumulation rate of dry matter in organs of storage products, prolonged the number of days of accumulation and increased economic coefficient, with 48.58% ~ 57.47% The number of suitable fruit nodes was 94.7 ~ 105.5 m-2 leaves, which increased the leaf volume per unit area and the dry weight of reproductive organs, which were 27.38 ~ 32.03 m-2 leaves, respectively. 1637 ~ 0.2303kg · m-2 leaves, leaf boll ratio of 2.5 ~ 3: 1. This is a measure of cotton source library coordination of important physiological indicators.
