目前,银耳菌种质量不够稳定。我们试图用耳木分离法,定向筛选早熟、高产、质优,适宜木屑栽培的银耳菌株。种木选择及预处:人工栽培的段木,需选早熟,出耳率高,朵型大,耳片疏松,色白的段木;若选野生银耳,应尽量寻找坚实少朽的木头;木屑瓶、袋中长有银耳的下端基质,也可以挖取出来供分离。由于耳木湿度大,常带有病虫,可将耳木风干(耳片干缩),然后放入杀虫剂中弃虫1～2天。菌株分离及菌落挑取:从耳基部位附近挑取少许木屑,分接于试管斜面上,置25℃下10～25天。各试管可能出现下列情况:①斜面长满杂菌;
At present, the quality of fungus species is not stable enough. We tried to use ear separation method, directional screening of precocious, high yield, high quality, suitable for sawdust cultivation of fungus strains. Seed selection and pre-selection of wood: Artificial cultivation of wood, the need to be elected precocious, high ear rate, type large, loose ears, color white section of the wood; if selected wild Tremella, should try to find solid and rotten wood; wood chips Bottles, bags have white fungus at the bottom of the matrix, you can also dig out for separation. As the ear wood humidity, often with pests, ear dried can be dried (ear shrinkage), and then into the insecticide 1 to 2 days. Strain isolation and colony picking: pick a little sawdust from the vicinity of the ear base, tap the tube ramp, set at 25 ℃ for 10 to 25 days. The test tube may appear the following conditions: ① ramp covered with bacteria;
