双孢蘑菇(A.Bisporus)是目前世界上栽培面积最多的食用菌之一,而我国的出口总量占世界生产总量的1/5。但目前我国的单产水平很低,上海地区也仅1斤/尺~2左右,为了进一步发展我国的蘑菇生产,提高单产水平,我们既要改革、完善栽培管理措施,创造最佳的生态条件,来满足蘑菇生产的需要。更重要的是要筛选、培育高产的菌株。根据1982年5月在福建省福州市召开的华东六省一市蘑菇协作组会议对蘑菇选育种的要求,我们进行了菌株对比试验。现将两年来的工作总结如下。一、材料和方法1.供试菌株:系双孢蘑菇,共15个菌株。各菌株的来源、形态及表现详见表1。2.培养料配比、堆 A. Bisporus is one of the most cultivated edible mushrooms in the world at present, and our country’s total export volume accounts for 1/5 of the world total. However, at present, the yield level in China is very low, only about 1 kg / ft ~ 2 in Shanghai. In order to further develop the production of mushrooms and raise the yield level in China, we must reform and perfect cultivation management measures to create the best ecological conditions, To meet the needs of mushroom production. More important is to screen and cultivate high-yielding strains. According to the requirement of mushroom selection and breeding at the Meeting of Mushroom Collaboration of East China, Six Provinces and One City, held in Fuzhou, Fujian Province in May 1982, we conducted a comparative test of the strains. The work of the past two years are summarized below. First, the material and methods 1 test strains: Department of Agaricus bisporus, a total of 15 strains. The origin, morphology and performance of each strain are shown in Table 1.2
