塑膜育苗移栽棉花大面积推广以后,育苗基地约占棉田面积10%。床地移栽棉花由于迟栽晚发、结铃少、铃重轻、产量产值低。为了提高床地棉花产量,我们在生产实践中。试行棉花苗床留苗技术,取得了显著的增产效果。据调查床地留苗錦花比同床移苗棉花亩铃数增加15.8～78%,单铃重增加0.86克左右,亩增皮棉22～79.6%,平均增产34%左右。其栽培技术如下: Plastic film nursery cotton transplanted a large area after the promotion, nursery base accounts for about 10% of cotton area. Cotton bed transplanting late late as late, less bolls, bolls light weight, low production value. In order to improve the bed cotton production, we are in production practice. Trial cotton seedling seedling technology, and achieved remarkable yield increase. According to the survey bed stay Miao Jin than the same bed Miao Mian cotton acre increased 15.8 ~ 78%, a single boll weight increased about 0.86 grams, mu lint cotton 22 ~ 79.6%, an average yield of about 34%. The cultivation techniques are as follows:
