我县人工木棒栽培银耳已有十余年,年产量十万斤左右,是山区社队一项主要致富门路。根据历年来的调查,单产很不一致,少数高产典型百斤段木可产干耳二斤以上,差的百斤段木只收几两,绝大部份产量在一斤左右。为什么银耳产量这样悬殊?我们通过调查和试验,初步认为影响银耳产量的有以下几个方面: (一)菌种质量与产量的关系。分离或引进的母种,在扩大培养过程中,能否将其母种原来的优良性状比较稳定地保存下来,将是保证菌种质量的关键。银耳菌种是由银耳菌丝和伴生菌组成的,在育种过程中既要考虑到营养、温度、湿度、通风、酸碱度等因子,还要注 County artificial wooden stick cultivation Tremella has been more than ten years, annual output of about one hundred thousand jins, is a major community riches mountain community. According to the survey over the years, yield is very inconsistent, a few high-yielding typical peanuts can yield dry ears more than two pounds, poor wood only received a few pounds, most of the output in a pound. Why the production of such a huge white fungus? We through the investigation and experiments, initially believed that the impact of white fungus production in the following areas: (A) the quality of the strain and the relationship between yield. Separated or introduced the mother species, in the expansion of culture process, whether the mother of the original elite traits preserved relatively stable, will be the key to ensuring the quality of the strain. Tremella species is composed of fungus hyphae and associated bacteria in the breeding process, it is necessary to take into account nutrients, temperature, humidity, ventilation, pH and other factors, but also note
