近几年来,格达良乡高密度棉田每年发生不同程度的早衰现象,部分棉田发生严重,到9月下旬全田棉花70%早衰死亡,且有逐年加重的趋势。有超过40%左右的棉田秋桃未保住,直接影响棉花产量,难以确保高产田和超高产田总铃数。
In recent years, the high-density cotton fields in Qediangliang Township experienced various degrees of premature aging each year, with some cotton fields seriously affected. By the end of September, the death rate of 70% premature aging cotton fields was all over the world, and there was a trend of increasing year by year. More than 40% of cotton fields in autumn are not preserved, which has a direct impact on cotton production, making it difficult to ensure the total number of bolls in high yield fields and super high yield fields.
