双孢蘑菇菌株在杏鲍菇菌糠中的发菌情况及适宜菌种筛选

以4个双孢蘑菇菌株As2796、W192、W136、W20为材料,观察其在杏鲍菇菌糠栽培基质上的发菌状况及产量。结果表明,4个供试菌株在杏鲍菇菌糠基质上均可发菌,表现最好的为W192菌株,其菌丝发菌速度快、长势强、菌丝长满料层的时间短(19 d),发菌至出菇时间为45 d,菌丝稠密而整齐、颜色洁白;其次为As2796和W136,菌丝发菌速度较快,菌丝长满料层的时间为20 d,发菌至出菇时间分别为46 d和47 d,菌丝稠密而整齐、颜色洁白;较差的为W20,菌丝发菌速度慢、长势弱,菌丝长满料层的时间为21 d,发菌至出菇时间为49 d。子实体表现最好的为W192,其菌盖大小适中且厚,直径为3.85 cm,厚度为2.16 cm,菌柄粗短,不易开伞,菇质最好;其次为As2796和W136,菌盖厚度分别为2.13 cm和2.14 cm,直径为3.89 cm和3.25 cm,菌柄略细微长,菇质中等;较差的为W20,菌盖薄且小,厚度为2.10 cm,直径为3.13 cm,菌柄细长,菇质较差。W192产量最高,达到53.44 kg/m~2;其次为As2796和W136,分别达到46.73 kg/m2和44.43 kg/m~2;产量较差的为W20,仅42.53 kg/m~2。

Spore Germination of Agaricus bisporus on Pleurotus eryngii Matrix and Screening of Appropriate Strains

Four strains(As2796,W192,W136 and W20) were used as materials to observe the sporocarp growth and yield of Agaricus bisporus on fungus chaff of Pleurotus eryngii.The results showed that the spore germination of all the four strains of Agaricus bisporus occurred on the fungus chaff of Pleurotus eryngii,and the best one was W192,of which hyphae germinated faster and grew well,taking 19 d to cover the matrix layer and 45 d to pick up mushrooms,with dense and neat hyphae and white color.Followed by As2796 and W136,of which hyphae germinated faster,taking 20 d to cover the matrix layer,and 46 d and 47 d respectively to collect mushrooms,being dense and neat,with white color.W20 was the worst,of which hyphae germinated slowly and grew weak,taking 21 d to cover the matrix layer,and 49 d to collect mushrooms,dense and neat with white color.The best sporocarp was also W192,of which the cap was proper of size and thick with diameter of 3.85 cm and thickness of 2.16 cm,the stipe was stubby,the mushroom umbrella did not open easily and the quality was best.Followed by As2796 and W136,for which the cap thickness was 2.13 cm and 2.14 cm respectively,the diameter was 3.89 cm and 3.25 cm respectively,the handles were slightly longer and the quality was medium.The worst was W20,of which the cap was thin and small,with thickness of 2.10 cm and diameter of 3.13 cm,the handle being long and thin,and its quality was poor.In addition,W192 had the highest yield of 53.44 kg/m2,followed by As2796 and W136(46.73, 44.43 kg/m2 respectively);W20 was the lowest,with a yield of 42.53 kg/m2.
