在当前的食用菌生产中,一个比较突出的问题是,菌种难以就地解决。因此,就地兴办菌种厂将是产菇乡镇一个可以开发的高效益项目。1.菌种有三级一级种,又叫母种,是直接用食用菌的孢子或组织分离培养(也可用从有关科研单位购进的试管种培养)而成;二级种,又叫原种,是由母种转接扩繁 In the current edible fungus production, a more prominent problem is that the strain is difficult to solve on the spot. Therefore, the local establishment of bacteria plant will be mushroom production township can be developed a high-efficiency projects. 1. Strain There are three levels of a species, also known as the mother species, is directly spores or tissue culture of edible fungi (also available from the scientific research units purchased test tube species) made; two species, also known as The original species, is transferred by the mother species expansion
