段木栽培木耳,经常会碰到因接种失败而影响产量的情况.这可能与栽培种培养基配方有关.为此,笔者从1990～1991年进行了栽培种培养基不同配方对比试验.现将结果报告如下:(一)试验材料 菌种引自华中农大的黑人901.母种培养基为PDA.原种为竹签培养基,先将无霉变的干竹签放在水中(100kg水+10g磷酸二氢钾+1g硫酸镁)煮沸1小时,沥于后再与木屑培养基(木屑78%,麸皮20%,糖和石膏各1%)拌匀,装瓶、灭菌.(二)试验方法①栽培种配方:A. 木屑78%,麸皮20%,糖、石膏各1%;B.木屑90%,麸皮8%,糖、石膏各1%;C.杂木屑89%,麸皮10%,石膏1%;D.杂木
Parasite cultivation of fungus, often encountered due to inoculation failed to affect the yield situation.This may be related to cultivar medium formula.To this end, the author from 1990 to 1991 for different varieties of cultivated medium contrast test will now The results are reported as follows: (a) Test material The strain is quoted from blacks of Huazhongnongda 901. The mother cultivar is PDA, the original is bamboo shoot medium, and the moldy dried bamboo is first placed in water (100kg water + 10g potassium dihydrogen phosphate + 1g magnesium sulfate) boiled for 1 hour, leached and then mixed with sawdust medium (sawdust 78%, bran 20%, sugar and gypsum 1%), bottling, sterilization ) Test Method ① Cultivation formula: A. Sawdust 78%, bran 20%, sugar, gypsum each 1%; B. sawdust 90%, bran 8%, sugar, gypsum each 1%; C. sawdust 89% , Bran 10%, gypsum 1%; D. Zamu
