在食用菌的生产过程中,经常遇到菌种退化、产量降低等同题.为了解决这一问题,必须不断地选育新菌种.常用的育种方法是组织分离和孢子分离.笔者在实践中摸索了一种混合培养法,现简介如下:(一)材料菌种育猴头和平菇.斜面和甲板培养基均为土豆蔗糖培养基.原种、栽培种培养料配方为棉子皮78%、麸皮20%、糖和石膏各1%、磷酸二氢钾0.1%、硫酸镁0.1%、料水比1∶1～1.05.(二)方法①混合培养:将猴头和平菇菌种混合培养于同一斜面上,基本长满斜面后用蜡封口,置冰箱
In the production of edible fungi, often encountered strain degeneration, yield reduction equivalent to the problem.In order to solve this problem, we must constantly breeding new species. Common breeding methods are tissue separation and spore separation. In a groping of a mixed culture method, are summarized as follows: (A) material bacteria breeding Hericium ermine and mushrooms.The slope and deck medium are potato sucrose medium.Original species, cultivar culture material formula for the cotton seed skin 78 %, Bran 20%, sugar and gypsum 1%, potassium dihydrogen phosphate 0.1%, magnesium sulfate 0.1%, water ratio of 1: 1 to 1.05 (B) method ① mixed culture: Mixed training in the same bevel, basically covered with a beveled wax, set the refrigerator
