我县从1981年开始推广阳畦栽培平菇,近几年每年的投料量(棉子壳)在700吨左右.虽然平菇对生活条件要求不很严格,但每年都有部分菇农栽培失败.现将其失败的原因及防止措施谈点浅见.(一)菌种块发黄,菌丝萎缩产生原因:①栽培期气温高,畦面覆盖物薄,料温长时间超过40℃.②高温季节栽培,料厚或料堆制发酵未达到要求,播种后培养料继续升温发酵.③培养料内带入或栽培床地发生食菌丝的螨类.防止措施,在高温季节栽培平菇,场地应尽可能选在有遮荫处,料面整成龟背形,料床内要开沟,畦面覆盖物要厚一点,高温期中午要进行喷水降温.一般培养料不需堆制发酵,对培养料质量
Since 1981, my county has promoted the cultivation of Pleurotus ostreatus, and in recent years, the annual feed amount (cotton seed shell) is about 700 tons. Although Pleurotus ostreatus does not require strict living conditions, some mushroom cultivation fails each year. Now the reasons for the failure and prevention measures to talk about the point of view. (A) Yellow yellow bacteria, mycelium atrophy causes: ① high temperature during cultivation, mulberry surface cover thin, material temperature for a long time over 40 ℃. ② high temperature Season cultivation, material thickness or material heap fermentation system does not meet the requirements, sowing the culture material to continue heating and fermentation .③ culture material into the or cultivation bed occurs mites mycelium.Prevention measures, cultivation of mushrooms in the hot season, Venues should be selected as far as possible in the shade, the material into a turtle shape into the whole shape, the material bed to be ditched, 畦 surface cover to a little thick, high temperature at noon to be spray cooling. Fermentation, the quality of culture materials
