棉花适期早播是促苗早发稳长,夺取优质高产的关键措施.而在实际生产过程中,往往因春旱无雨,不能做到适期播种,或因造墒后遇雨推迟播种时间,造成出苗晚,开花结铃晚,优桃少,影响棉花品质和产量.为解决棉花晚播与优质的矛盾和高旱地棉花迟发、霜前花少、品质差等问题,我们于1987～1988年对晚播棉田和因干旱迟发的棉田,进行了密植早打顶栽培试验,取得了优质、低成本、高效益效果.一、基本情况试验地为砂壤土,地势高燥、平坦,肥

Early cotton sowing is the key to promote early seedlings grow steadily, to seize high quality and high yield.In the actual production process, often due to spring drought, can not be sowing, or postpone planting due to rain after planting Time, resulting in late emergence, flowering bolls late, less peach, affecting cotton quality and yield .To resolve the contradiction between late sowing cotton and high quality cotton in late spring drought, frost less flowers, poor quality, we 1987 ~ 1988 on late-sowing cotton fields and cotton fields due to late onset of drought, carried out a close planting cultivation experiments, and achieved high-quality, low-cost, high efficiency results.First, the basic situation for the test of sandy loam, high terrain dry, flat ,fat
