近年来,麦粒种之所以推广很快,是囚为麦粒营养丰富,麦粒种菌丝洁白、粗壮、生长快、耐保存、成活率高等优点。然而不同配制的麦粒培养基,所得到的菌种效果差异很大。为解决这个问题,笔者从1994年开始进行试验,现将试验结果报告如下; (一)培养基配方 ①对照组:麦粒90％,干牛粪8％,石膏粉、轻质碳酸钙各1％。②试验组:麦粒80％,麸皮8％,干牛粪10％,石膏粉、轻质碳酸钙各1％。 (二)菌种制作程序 ①对照组:将麦粒用1％的石灰水浸泡8～12小时,捞起后用清水冲洗干净,滤干放入100℃开水锅内蒸煮30分钟,焖1～2小时,而后加入石膏粉、轻质碳酸钙,拌匀后pH为7～8,装好瓶,用备好的牛粪粉封口,在压力1～1.5kg/cm~2、温度121℃条件下灭菌2～3小时,冷却至室温接种,置20
In recent years, the reason why the promotion of wheat seed quickly, is prisoners nutritious wheat, wheat mycelium white, stout, fast growth, preservation, survival rate advantages. However, different formulations of wheat grain medium, the resulting strains vary widely. To solve this problem, the author started the experiment from 1994, the test results are reported as follows: (a) medium recipe ① control group: wheat 90%, dry cow dung 8%, gypsum powder, light calcium carbonate each 1 %. ② experimental group: 80% wheat, wheat bran 8%, dry cow dung 10%, gypsum powder, light calcium carbonate 1%. (B) strain production procedures ① control group: the wheat grains soaked in 1% lime water for 8 to 12 hours, picked up and rinsed with water rinse, dried into the boiling water at 100 ℃ cook 30 minutes, simmer 1 ~ 2 hours, and then add gypsum powder, light calcium carbonate, mix well pH 7 ~ 8, bottled, sealed with prepared cow dung powder, under the pressure of 1 ~ 1.5kg / cm ~ 2, temperature 121 ℃ conditions 2 to 3 hours under sterilization, cooled to room temperature inoculation, set 20
