【摘要】 利用平板稀释涂布培养法,分析高温双环蘑菇5种覆土在覆土后菌丝生长期和子实体生长期细菌消长规律。结果表明,不同覆土中的细菌数量均随着高温蘑菇菌丝的生长而增多,不同覆土细菌数与其中的蘑菇菌丝生长量成正相关;覆土后细菌数于原基形成时达到首个峰值,进入子实体生长期后,覆土层中的细菌数明显下降,至子实体采收时为低谷,采收后随着蘑菇菌丝的恢复生长,细菌数又迅速回升,表明覆土中细菌的消长与蘑菇菌丝生长代谢强弱成正相关。更多还原

【Abstract】 The growth and decline regularity of bacteria in 5 different casing soils were investigated by using plate culture techniques, the soil samples were collected during different growth periods of Agaricus bitorquis. Results revealed that bacterial populations increased with mushroom mycelial growth in casing soil, the bacterial populations in different casing soils were in direct proportion to the quantity of mushroom mycelia in casing soil. Of all casing soils, the bacterial populations increased to a peak point when primordium formation, and then decreased to a valley point before harvest, but the bacterial populations increased again rapidly after harvest when mushroom mycelia return to growth, it indicated that the growth and decline regularity of bacteria in casing soil was in direct proportion to the activity of mushroom mycelial growth and metabolism.更多还原
