一九八四年五月上海市食用菌菌种站接受国际友人馈赠的香菇新菌株。通过出菇试验,从中选出了一批种菇用组织分离法得到一个编号为L-8450(8517)的新菌株。经过对该菌株的反复测试,发现该菌株比上海郊区目前生产上采用的中低温型香菇当家品种7402有较明显优势。目前试种面积已达三十万平方尺左右;经济效益显著,受到广大菇农欢迎。现总结报道如下: 一、材料和方法 (一)供试菌株 L-8450(8517),以下简称8450,以7402为对照。 (二)制种和栽培方法 1.母种采用
In May 1984, Shanghai Edible Fungus Strain Station received new mushroom strains from international friends. Through the fruiting experiment, a batch of mushrooms was selected and a new strain L-8450 (8517) was obtained by tissue separation method. After repeated tests of this strain, it was found that the strain had obvious advantages over the low-temperature-type mushroom-headed cultivar 7402 currently used in Shanghai suburbs. The current test area has reached about 300,000 square feet; significant economic benefits, welcomed by the majority of mushroom farmers. Now summarized report as follows: First, materials and methods (A) test strain L-8450 (8517), hereinafter referred to as 8450 to 7402 as a control. (B) seed and cultivation methods 1.
