贴芽补种法是劳模吴吉昌同志创造出来的棉花补苗方法,是继芽苗移栽的新发展。1965年山西闻喜县东镇棉花样板田棉花播种后,连续四次降雨达64.5毫米,地温猛降,到4月30日最低,仅达5—7℃,形成低温高湿环境条件,严重威胁着棉苗出土。吴吉昌劳模针对不同缺苗程度提出了四道防线保全苗的措施,即缺苗20%以下时用芽苗移栽(两叶期以后带土移栽),缺苗30—40%时用贴芽补种, The bud bud replanting method is a cotton seedling cultivation method created by Comrade Wu Jichang and is a new development of sprout seedling transplanting. 1965 Shanxi Wenxi County, Dongzhen, cotton samples Cotton field planting, continuous rainfall of 64.5 mm four times, ground temperature plummeted to the lowest on April 30, only 5-7 ℃, the formation of low temperature and humidity environmental conditions, a serious threat Cotton seedlings unearthed. Wu Ji-chang model workers for different degrees of lack of seedlings proposed four measures to protect the whole line of seedlings, that is, when the seedlings less than 20% with sprouts transplanting (two-leaf stage with soil transplanting), 30-40% replant,
