近年来,我国金针菇生产发展迅速,许多单位引进我所选育的三明一号和日本信浓二号等菌株。三明一号菌株出菇快,栽培周期短,产量高,菇形圆整,菌柄较粗壮、抗病力强。经多年栽培,产质量稳定,但菌盖肉薄,较易开伞,菌柄基部也易褐变,制罐产品色泽较深。而日本信浓二号菌株菇体洁白,菌盖内卷,肉厚,开伞慢,较适合制罐,但出菇慢,栽培周期长,抗病力差,产量低,生物效率仅25～60%。为了选育出更优良的金针菇栽培菌株,笔者从1983年开始以这两个菌株为杂交亲本,进行杂交育种研究,获得了一批杂交菌株,其中19号菌株经四年的栽培结果表明,是
In recent years, the rapid development of Flammulina velutipes production in our country has led many units to introduce the strains of Sanming I and Shinano II that I have selected. Sanming No.1 strain fruiting quick, short cultivation cycle, high yield, mushroom-shaped round, stout stout, strong resistance. After years of cultivation, the quality of production and stability, but the cap thin, more easy to open umbrella, base stigma is also easy to brown, deep-tinned product. The Japanese Shinano no. 2 strain mushroom white, covered with cap, meat thick, slow opening, more suitable for canning, but slow fruiting, long cultivation period, disease resistance is poor, low yield, biological efficiency of only 25 ~ 60%. In order to breed better Flammulina velutipes cultivated strains, the author began in 1983 to these two strains of hybrid parents, cross breeding study, access to a number of hybrid strains, of which strain No. 19 after four years of cultivation showed that the
