(一)选用优质高产菌种优质的黑木耳菌种,除保持产量高、抗逆性强、成活率高、朵大、出耳多等优良性能外,在生产中必须具备:菌丝粗壮密集、颜色洁白、上下一致、呈细羊毛状,菌丝在培养基上蔓延时齐头并进.菌丝长满瓶后,一般会出现米黄色色素,这种色素会使培养基变成褐色.瓶口的培养基表面有牛角状耳芽,沿瓶壁的培养基表面会出现菊花状耳芽.另外,菌种没有干涸收缩现象,菌龄不超过2个月.
(A) the selection of high-quality high-quality strains of fungus Auricularia species, in addition to maintaining high yield, strong resistance, high survival rate, big flower, ears and other excellent performance, the production must have: thick mycelium intensive , The color is white, up and down the same, was fine wool, mycelium go hand in hand when the medium spread mycelium over the bottle, the general will appear beige pigment, this pigment will make the medium brown. There are horn-shaped ear buds on the surface of the culture medium, and chrysanthemum-like ear buds appear on the surface of the culture medium along the wall of the flask body. In addition, the strain does not dry and shrink, and the age of the bacteria does not exceed 2 months.
