随着食用菌的发展,由于广泛使用棉子壳为培养料,使棉子壳价格不断上涨。为降低成本,生产中需开发其他原料,在南方大量油茶壳被作为薪柴烧掉。本试验是通过棉子壳与油茶壳不同配比对黑木耳生长及产量影响,筛选出最佳培养料配方。现将结果简报如下。 一、材料与方法 (一)供试材料 菌种为沪耳1号,引自上海农科院食用菌所。培养料配方,①棉子壳100％;②棉子壳50％,油茶壳50％;③棉于壳60％,油茶壳40％;④棉子壳70％,油茶壳30％;⑤棉于壳80％,油茶壳20％。各配方中另加麸皮8％,石膏和过磷酸钙各1％,料水比1:1。 (二)试验方法 先按比例称取干油茶壳,用1％石灰水浸泡24小时,沥于水、称重,再加其他原料及水拌匀,配料加水时要减去油茶壳吸收的水分。料拌好后装入规格为17×32cm袋中,加棉塞扎口,于100℃灭菌10小时,4月8日接种,在25℃下培养菌丝,5月20日开袋出
With the development of edible fungus, the price of cottonseed shells keeps rising due to the widespread use of cottonseed shells as the cultivation material. In order to reduce costs, other raw materials need to be developed in production, and a large number of Camellia shells are burned as firewood in the south. This experiment is through the different ratio of cotton seed hull and Camellia black fungus growth and yield, screened the best training material formula. The result is now as follows. First, the material and methods (a) for the test material strain Shanghai ear on the 1st, cited from the Shanghai Institute of Agronomy. Training material formula, ① cotton seed hull 100%; ② cotton seed hull 50%, 50% tea hull; ③ 60% cotton in the shell, oil tea shell 40%; ④ cotton seed hull 70%, 30% Shell 80%, Camellia shell 20%. Each formula plus bran 8%, 1% of gypsum and superphosphate, water to water ratio of 1: 1. (B) Test Method Weigh the proportion of dry oil tea shell, soaked in 1% lime water for 24 hours, leaking in water, weighed, together with other raw materials and water mix well, when the ingredients add water to subtract the moisture absorbed by Camellia shell . Mix well into the specifications for the 17 × 32cm bag, add tampon mouth, sterilized at 100 ℃ 10 hours, April 8 vaccination, cultured mycelium at 25 ℃, May 20 to open the bag
