CCEF89是1991年An河北省食用菌研究所引进的几个品种中驯化选育出的一个优良菌株。几年的试验和推广表明，该菌株在山东适应性很强，尤其是该菌株的抗杂性、菇的质量和产量均名列前茅。目前该品种栽培量不断增加，有希望成为山东省的当家品种。现将生物学特性及高产栽培技术介? CCEF89 is an excellent strain domesticated and breeding in several varieties introduced by Hebei Edible Mushroom Research Institute in 1991. Several years of experiments and promotion show that the strains in Shandong adaptability, especially the anti-hybrid strains, mushroom quality and yield are among the best. At present, the varieties of cultivated increasing, promising to become the mastermind of Shandong Province. Now the biological characteristics and high yield cultivation techniques
