室外纯长稻草栽培平菇是食用菌生产上最经济适用的栽培方法。近年来,笔者在普通栽培的基础上经过反复实践,摸索出一套切实可行的措施。1990年冬天用100公斤纯长稻草栽培平菇,收获鲜菇118.6公斤,生物效率达118.6％。菇农丁小林首次试种,用稻草25公斤,产菇32.2公斤,生物效率为128.8％。许多菇农运用这种方法栽培,均反映很好。 室外纯长稻草栽培平菇关键应注意如下二点: 1.选择适宜品种 经引种“吃草性”好的平菇品种进行比较,筛选出“831”、“昆26”和从“831”分离出的新菌株“P_(26)选”等表现较 Pure long straw outdoor cultivation Mushroom cultivation of edible mushrooms is the most economical cultivation methods. In recent years, on the basis of ordinary cultivation, the author went through repeated practice and worked out a set of practical measures. In the winter of 1990, 100 kg of pure long straw was used to grow Pleurotus ostreatus, and 118.6 kg of fresh mushrooms were harvested. The biological efficiency reached 118.6%. Mushroom farmers Ding Kobayashi first test, with straw 25 kilograms, mushroom production 32.2 kilograms, the biological efficiency of 128.8%. Many mushroom farmers use this method of cultivation, are reflected very well. The key points of outdoor pure long straw cultivation of Pleurotus ostreatus should pay attention to the following two points: 1. Select the appropriate varieties by introduction of “grazing” good Pleurotus species are compared to filter out “831”, “Queensland 26” and from the “831” separation Out of the new strain “P_ (26) election” and other performance than
