栽培食用菌普遍采用斜面母种制作原种,再扩大制成栽培种的方法。我们在1993年上半年,对小平菇用液体菌种制作原种和栽培种进行了栽培试验。试验表明,用液体种栽培小平菇具有发茵快、菌丝壮、出菇早而整齐、生长期短等优点。现将结果报告如下: (一)材料 供试小平菇菌种引自山西省原平农校。培养液配方为葡萄糖1g,黄豆粉1.5g,玉米粉4g,羧甲基纤维素0.2g,加水至100ml。培养料配方为棉子壳90％,麸皮5％,葡萄糖、石膏、磷肥、石灰各1％,
Cultivation of mushrooms commonly used slant mother species of the original species, and then expand the method of making cultivated species. In the first half of 1993, we conducted cultivation experiments on the production of original and cultivated species of Pleurotus ostreatus using liquid strains. Experiments show that the cultivation of small mushrooms with liquid species with Yin rapid, strong mycelium, fruiting early and neat, short growth period and so on. The results are reported as follows: (A) for the test materials Mushroom species from the original farm in Shanxi Province. The culture solution formula 1g of glucose, soybean powder 1.5g, corn flour 4g, carboxymethyl cellulose 0.2g, add water to 100ml. Training materials formula for the cotton seed shell 90%, bran 5%, glucose, gypsum, phosphate fertilizer, lime, 1%
