我们这里属特早熟棉区。无霜期短与棉花生育期长的矛盾比较突出。当前,影响我区棉花产量的主要因素是垅大苗稀,生育偏晚,枯黄萎病严重,群众叫做“稀、晚、病”。先进社队实行“密、早、抗”,改变“稀、晚、病”,使棉花亩产达到100—150斤。密,合理密植主要抓了“改、缩、补,借”四个字。改,就是打垅时把1.7—1.8尺的大垅改成1.3—1.4尺的小垅,小垅面积占棉田总面积的92%。缩, We are a very precocious cotton area here. The conflict between frost-free period and long-term cotton growing period is prominent. At present, the main factors affecting the cotton yield in our district are the large seedling shortage, the late birth and the serious yellow wilt disease. The masses are called “thin, late and sick.” Advanced team to implement “secret, early, anti”, change “thin, late, sick”, so that cotton yield reached 100-150 pounds.
