麦套棉比纯作棉吐絮期偏迟,后发性较强,在今年前期干旱、中期多雨的气候条件下,上部结桃多。加强吐絮期管理,一是保叶、保根,使根系保持吸收能力,确保棉铃所需的有机养料;二是为棉铃正常吐絮创造良好环境条件,加速棉铃内部有机养料的转化,促早熟、防早衰、增铃重、增衣分,提高棉花产量和纤维品质,具体抓好5项培管技术措施:1、窨水抗旱。棉花吐絮期虽然耗水量较少,只占全生育期耗水量的16～20%,但还需要一定的水分供应,维持棉株正常的生理活动,此时棉根吸收肥水的能力减弱,窨水后能促进根系对养分的吸收作用。当土壤水分低于田间持水量的60%以下时,当棉花顶部叶片中午呈萎蔫下垂表现或土壤含水量低于15%以下时,应立 Wheat cotton than pure cotton boll opening late, strong after-onset drought earlier this year, the mid-rainy weather conditions, the upper part of the peach more. Strengthen the management of boll opening period, the first is Paul leaves, Paul root, so that the root system to maintain absorptive capacity to ensure that the necessary cotton boll nourishment; Second, the normal boll boll boll to create good environmental conditions and accelerate cotton bolls within the transformation of organic nutrients, and promote early maturity Premature aging, boll weigher, add clothing points, improve cotton yield and fiber quality, do a good job of five technical measures for culture control: 1, swill drought. Cotton boll-opening period, although less water consumption, only accounts for 16 ~ 20% of the water consumption during the whole growth period, but also requires a certain amount of water supply to maintain the normal physiological activity of cotton plants. At this time, the ability of cotton roots to absorb fertilizer is weakened. After the root can promote the absorption of nutrients. When the soil moisture is less than 60% of the field water holding capacity, when the cotton top leaves at noon showed wilting sagging or soil moisture content below 15%, should stand
