长期极高温天气条件菌种对平菇产量影响试验

试验研究了长期极高温天气大棚条件下培养的平菇菌种和空调控温条件下培养的菌种，经过继续种植对菌丝和产量的影响，并对不同颜色的菌种和不同部位菌种对平菇菌丝生长和子实体发育的影响做了详细的比较。结果表明，对于灰黑色平菇2016而言，经历超高温天气下培养的菌种使生物学效率降低了17％也1．6％，使用菌袋外部厚度2cm的菌种比2cm以内菌种生物学效率提高了6．4％～11．0％。对于灰白色平菇F803而言，经历高温菌种使生物学效率提高了3．9％-5．9％；外部2cm厚度的菌种比2cm以内菌种生物学效率降低了1．7％～3．7％。总之，灰黑色品种没有灰白色品种耐热．在高温季节使用灰白色品种对食用菌生产可能更好。

Discussion on Super High-temperature Weather and City Construction

With the method of structure analysis, this work analyzes the real data of the high-temperature weather of China in 2003 and those in history, and finds out that the structure character of the high-temperature weather process corresponds to the distribution of urban buildings. The result shows that excessive dense buildings could influence the atmosphere structure, which leads to the urban temperature increasing sharply. On the other hand, the structure analysis also reveals some problems on urban construction, and the corresponding countermeasure is an efficient method for high-temperature weather forecast.
