通常把棉铃生理机能衰亡前受病菌侵染而致的病害称为铃病,俗称烂铃。而不包括棉花采摘阶段因棉铃生理机能衰亡所诱致的生物霉烂。近年来,由于秋雨连绵,以致大面积棉花遭受霉烂,所以生产中也多把霉烂当作“烂铃”。如果只注意铃病防治,不考虑霉烂,仍达不到生产的目的。此外,铃病、霉烂界线不清,不仅不利于区别对待、深入研究,更不能得到有效的控制。一、生物霉烂的发生棉花进入吐絮后,生命力基本停止,此时若遭阴雨高湿即可诱致霉烂,所以生物霉烂主要发生于9月份的低温高湿阶段,而铃病则主要发生于8月份的高温高湿阶段。通过镜检,导致霉烂的有害微生物主要
The disease caused by pathogen infection before the physiological function of cotton boll is usually called bell disease, commonly known as rotten bell. It does not include the biological mildew caused by the decline of the physiological function of cotton bolls during the cotton picking stage. In recent years, as a result of the continuous autumn rains, mildew on large areas of cotton has been dampened. As a result, mildew is also regarded as “bad bell” in production. If you only pay attention to bell disease prevention and control, do not consider mildew, still can not achieve the purpose of production. In addition, the bell disease, moldy ill-defined, not only not conducive to discrimination, in-depth study, but can not be effectively controlled. First, the occurrence of biological mildew Cotton into the bream, the vitality of the basic stop at this time if the rain was wet and humid can cause mildew, so biological mildew mainly occurred in September low temperature and humidity stage, while the bell disease occurs mainly in August High temperature and humidity stage. Through microscopic examination, harmful microorganisms that cause mildew are mainly
