Strain characteristics and cultivation points of snow antler (Pleurotus eryngii) 251

The snow antler (Pleurotus eryngii) 251 strain (Pleurotus eryngii), newly selected by the Tillage Institute of Fujian Academy of Agricultural Sciences and the Institute of Plant Protection, belongs to the low temperature type, the period is short, generally 45-60 days; the variety is excellent, the yield is high, and the bioconversion rate is 70%-80%. It is welcomed by the growers in the extension area. Its characteristics and cultivation points are introduced as follows. 1 morphological characteristics: the cap width of fruiting body of strain 251was 60.8 cm, it was arcuate at first, the edge of cover was curled, then expanded, the center was slightly concave, showing funnel shape, and the surface of cap had dark brown fine stripes with silk radiation. The bacterial fold extends downward, milky white. Stipe 815 cm × 2.5 cm, partial or lateral, white to light yellow, medium solid, fleshy white fibrous. The spores are white. 2 cultivation points 2.1 cultivation materials sawdust 38%, cottonseed shell 40%, wheat bran 15%, corn meal 5%, sugar and gypsum 1% each. 2.2.The optimum temperature for mycelial growth and fruiting body development was 24 ℃ and 13 ℃, respectively. In this range, the mycelium could grow normally with fluctuation of 2 ℃. 2.3 the best local temperature for mushroom production should be selected in the cultivation season. Bags and inoculations should be made in Fuzhou in the middle of September, about the first ten days of November, and in late January in winter, and about the middle of March. 2.4.The mycelium of ① can grow in the bag for about 30 days, and the primordium can be seen on the material surface and the mouth of the bag. At this time, the mycelium can be moved into the mushroom room (cultivation room), remove the cotton plug and ring, straighten the mouth of the bag and arrange it neatly, then cover it with plastic film, wait for the primordium to differentiate into small mushroom bud, remove the plastic film, let the fruiting body grow normally, and the growth period is 45-50 days. ② ground sprinkles, the humidity of the mushroom is controlled at 85% and 95%. ③ regulates the light of the mushroom, and the fruit body development stage needs bright scattered light, which is slightly different from other mushrooms. ④ harvested in good time. Most of the snow antler 251 strains are solitary and clustered, with an average weight of about 60 g and more than 100 g. The commodity rate is high and can be harvested when there is a slight convexity in the center of the cap.
