笔者通过对陕西省秦巴山区黑木耳重点县的调查,认为该区提高黑木耳单产应重视以下技术问题;一、选用优良菌种秦巴山区黑木耳生产多在交通不便的深山区,人工科学养耳技术尚未被生产者重视,相当一部分山区农民还沿用古老的人工砍花、天然下种法。黑木耳产量低、耗初多。纯种栽培始于七十年代初期,多从外地引进菌种,当地菌种厂也分离一些菌种,大多数菌种不知系谱,随意编号、定名,因此生产上使用的菌种十分混
Through the investigation of key counties of black fungus in Qinba Mountains in Shaanxi Province, the author thinks that the following technical problems should be paid attention to in improving the yields of black fungus in this area. First, the selection of excellent fungus species of black fungus in Qinba Mountain area is mostly in the mountainous areas with inconvenient transportation. Ear technology has not yet been the producer of attention, a considerable part of the mountain farmers also follow the ancient artificially cut flowers, the natural method of planting. Black fungus production is low, consumption early. Purebred cultivation began in the early 1970s, the introduction of more species from the field, the local plant species also separated some strains, most strains of unknown pedigree, random number, named, so the production of bacteria are very mixed
