进入9月份后,棉花处于吐絮和秋桃成铃阶段,加强9月份后的培管,不仅可减少烂桃、减轻虫害,而且可以确保秋桃盖顶。据我站苗情观察,今年棉花从移栽到盛花期表现出如下特征:移栽到现蕾比历年早10天,是一个典型的早发年份。但6月下旬至7月普降暴雨,光照不足,棉花普遍渍涝严重,生长发育受阻,接着是连续高温干旱天气,使部分前期生长较好的棉苗生长势下降,到7月中旬出现了严重不平衡现象。通过7月份后的培管,棉苗生长虽然得到了较好的恢复,但仍显营养体不足。针对今年棉花生长的特点,在后期培管中应重点抓好四件事。
After entering September, the cotton is in the stage of boll opening and autumnal bolls. Strengthening the cultivation after September will not only reduce the rotten peach and reduce insect pests, but also ensure that the autumn peach will be covered. According to my station observation of seedling situation, this year cotton from transplanting to flowering stage showed the following characteristics: transplanting to budding than 10 years earlier than the calendar year, is a typical early years. However, heavy rains in late June to July, inadequate lighting, cotton, waterlogging generally serious, blocked growth and development, followed by continuous high temperature and drought weather, so that some of the early growth of better growth potential of cotton seedlings decreased to mid-July appeared Serious imbalance. After training in July, cotton seedling growth has been better recovery, but still showed lack of nutrients. In response to the characteristics of this year’s cotton growth, training should focus on four things in the post-training.
