冬季结冰的天气较多,如果防寒防冻,保温增温措施不当,在平菇产菇期的管理中极易发生瘤盖、粗柄、蓝色等三种畸形菇。 (一)瘤盖菇①症状:菇体生长发育极慢,菌盖表面出现瘤状或颗粒状的突起物,菇农称之为“起泡”或“起皱”,严重时菌盖僵缩,菇质硬化,停止生长。②发生原因:菇体生长发育期温度过低,且低温持续时间过长造成菌盖内外层细胞伸长失调而变形。这种现象在室内外菇场均有发生。③预防方法:购买菌种时必须了解该品种的最适温度范围
More cold weather in winter, if the cold frost, heat insulation measures improper warming in the management of mushroom production prone to tumor cover, stems, blue and other three kinds of mushrooms. (A) tumor cap mushroom ① symptoms: growth and development of mushroom body is very slow, the cap surface of tumor-like or granular protrusions, mushrooms called “blistering” or “wrinkling”, severe cap rigidity , Mushroom hardening, stop growing. ② causes: growth and development of mushroom body temperature is too low, and prolonged low temperature caused by the cover of the outer layer of cell cover dysplasia deformity. This phenomenon occurs in indoor and outdoor mushroom fields. ③ prevention methods: when buying species must understand the temperature range of the species
