姬松茸制种料与产量相关性研究简报

本文研究了采用五种不同制种料培养姬松茸(Agaricus biazei Murvill)菌种的生物学效率(产量)与菌丝生长速度、平均单朵重,子实体始菇期,子实体个数及污染串的关系。结果表明,生物学效率与菌丝生长速度、平均单朵重的相关性不显著,而与子实体始菇期、子实体个数。污染率的相关性达显著或极显著水平。五种制种料以稻草最好,稻草种发菌快,封面快,不易污染杂菌,成活率达100％,出菇早,生物学效率达40.67％,其次为木屑种及棉籽壳种。

A Preliminary Study on the Correlation between the Spawn Media and the Yield of Agaricus biazei Murvill

The relationship between the biological efficiency (yield) and the mycelium growth rate, the fruitbody formation period, the average weight per fruitbody, the number of fruitbody and the pollution rate of Agaricus biazei Murvill cultivated with five kinds of spawn media was studied in this paper. The results showed that the correlation between the biological efficiency, the mycelium growth rate and the average weight per fruitbody was not significant. However, the correlation between the biological efficiency, the fruitbody formation period, the number of fruitbody and the pollution rate was significant. The results suggested that the straw spawn had the advantages of high mycelium growth rate, early fruitbody formation period, high pollution resistant ability, 100 % survival rate and the highest yield with a biological efficiency of 40.67%, and that the less efficient spawns were sawdust spawn and cotton hull spawn.
