1983年笔者从本地许多野生菌株中,筛选出广温型平菇新菌株—8301。经连续三年试验观察,该菌株适应温度范围广,四季皆能出菇,生物效率稳定在100—120％。现将其经济性状和栽培特点介绍如下: 一、材料和方法供试品种 8301(采于本地一林场混交林地一枫杨树蔸上)、 In 1983, many wild strains from the local, I selected a wide temperature-type Pleurotus new strain -8301. After three consecutive years of experimental observation, the strain adapted to a wide temperature range, fruiting in all four seasons, and the biological efficiency was stable at 100-120%. Now the economic traits and cultivation characteristics are as follows: First, the material and method to test varieties 8301 (collected in a local mixed forest on a maple Poplar 蔸)
