我们这里每年都不同程度地发生棉花烂铃。一般在旱年、薄地较轻,涝年、丰产地较重。秋涝年份,有的生产队僵瓣花几乎占总收花量的四分之一。为防止烂铃,除了搞好棉花整枝、中耕、排水外,还要做到:(一)及时推株并垅,以增加光照,通风良好,促进早熟。凡湿度大,地力肥,生长旺盛,比较郁蔽的棉田,要及时进行推株并垅。用两手分开棉垅,扶住棉棵,两脚在基部向外侧踩踏。隔5—7日轮换一次,使受光均匀,如此进行三,四次即可。(二)摘除烂铃。棉铃腐烂后的损失程度与年份及感病早晚有 Cotton wears every year to varying degrees. Generally in dry years, thin to light, flood years, heavy yield heavier. Autumn flood years, and some production teams stiff petal flower accounts for almost a quarter of total revenue. In order to prevent bad bell, in addition to doing a good job of cotton pruning, cultivating, drainage, but also to do: (a) promptly push the plant and 垅, in order to increase the light, good ventilation and promote premature. Where the humidity, fertility, vigorous growth, more stagnant cotton fields, push the plant in time and 垅. Use both hands to separate the cotton 垅, hold the cotton tree, both feet stamped to the outside of the base. Alternate every 5-7 days, so that the light evenly, so three or four times can be. (B) removal of bad bell. Cotton boll rot loss and the year and the extent of the disease sooner or later
