闻喜县涑阳大队党支部书记吴吉昌同志,是全国著名的植棉劳模、农民科学家。解放前,吴吉昌是个种瓜的能手。解放后,他积极走合作化道路。二十多年来,认真研究棉花生产技术,围绕当地影响棉花生产的三个主要问题:前期低温难抓苗、中期荫蔽难抓桃、后期低温多烂桃,经过反复实践,先后摸索和创造出了:“冷床育苗”、“一窝双株”、“巧留油条”、“芽苗移栽”、“手捏蹲苗”、“闷芽穴播”、“贴芽补种”、“一株双秆”、“防雨灌花”、“计划整枝”、“多秆两层”等植棉新技术。形 Wuji Chang, secretary of Party Branch of Xingyang Brigade in Wenxi County, is a famous cotton model worker and farmer scientist throughout the country. Before liberation, Wu Jichang is a kind of melon master. After the liberation, he actively followed the path of cooperation. Over the past two decades, we have carefully studied the cotton production technology and focused on three major issues affecting cotton production in the region: the early low temperature was difficult to grasp the seedlings; the medium shade was difficult to grasp the peaches; the late low temperature and rotten peaches experienced repeated attempts to find and create “Cold bed nursery”, “a litter double strain”, “clever fritters,” “transplanting shoots”, “pinch Dunmiao”, “Sowing Buds”, “Bud Bud replanting”, “a Double stalk, ”“ rain and irrigation ”,“ plan pruning ”,“ multi-stalk two ”and other new cotton-planting techniques. shape
