利用食用菌純菌种来栽培各种食用菌,是提高食用菌的质量和促使早熟丰收的重要和最有效的措施。因为純菌种质量純淨无杂,菌絲生活力旺盛,接种床肥、草堆或段木上以后,很快就能萌发生長,对环境的适应性和抗逆力也比較强。且具有成活率高,出菇出耳时間快,产量高,质量好,使用方便,利于大量推广等等优点。現将培育食用菌純菌种,必須掌握的几个主要关鍵,介紹如后。一、选好种菌种菌必須选择朶大形正,生活力旺盛而又无病虫害的子实体,才能达到优质高产的目的。据个人多年实驗,采用孢子分离方法,一般要比用組織分离培养出来的純菌种,生活力旺盛,产质量也較高。蘑菇、草菇由于有菌环和脚苞的关系,只要在无菌操作条件下,通过特殊的装置就可采得純淨的孢 The use of pure mushroom species to cultivate a variety of edible mushrooms, is to improve the quality of edible fungi and promote early harvest the important and most effective measures. Pure pure quality without impurities, mycelium vitality, inoculation bed, hay or section of the wood after the rapid germination and growth, adaptability to the environment and resilience are also relatively strong. And has a high survival rate, fruiting ear out time, high yield, good quality, easy to use, conducive to the promotion of a large number of advantages. Now that purebred edible mushrooms should be cultivated, a few key points that must be mastered are described below. First, choose a good species of bacteria must choose a large positive shape, vitality and no pests and diseases of fruiting bodies, in order to achieve the purpose of high quality and high yield. According to personal experiments for many years, the use of spore separation methods, generally more than pure tissue culture with tissue culture, strong vitality, quality of production is also higher. Mushrooms, mushrooms due to bacteria ring and the relationship between the foot buds, as long as the aseptic operating conditions, through a special device can be obtained pure spores
