陈旧棉子壳生料栽平菇,在发菌期会出现污染,老菇房或栽培多年几经污染的环境,更令人担忧。一般生料栽培常在播种后10天左右,因大量霉菌污染而造成种菇失败。对菇房进行消毒,往往因条件不具备,难以做到彻底。改用熟料栽培,不但费工费燃料,增加成本,而且无法大量投料,生产规模受到限制。为此,笔者试用石灰水浸泡棉子壳、袋栽、室外地面掩埋发菌,避开发菌污染关,取得了一定效果。现总结如下。 一、试验环境及条件 (一)菇房 三间门朝南的菇房及40m~2庭院一间。菇房有8年种菇史,头两年春秋季用棉子壳生料压块室内栽平菇,均获好收成。第三年继续栽培,出现污染,以后逐趋严重。每次污染,都将污染块清除至室外;室内清扫,用石灰水冲洗消毒,再用常规法进行生料栽培,结果仍大量污染,以绿霉居多也有黑霉。说明菇房及环境已严重污染,难以进行生料栽培。
Obsolete cotton seed shell planted mushrooms, in the germ will be contaminated, the old mushroom house or cultivation of many years after the pollution of the environment, even more cause for concern. The general raw material cultivation is often about 10 days after sowing, due to a large number of mold pollution caused by mushroom failure. Mushroom room disinfection, often due to conditions do not have it, it is difficult to achieve thorough. Switch to clinker cultivation, not only fares fuel costs, increase costs, and can not be a lot of feed, the production scale is limited. To this end, I try lime soaked cotton seed hulls, bagged, outdoor ground buried bacteria, to avoid germs off, and achieved some results. Now summarized as follows. First, the test environment and conditions (A) Gu Fang three doors south of the mushroom house and 40m ~ 2 courtyard. Mushroom room has 8 years of history of mushrooms, the first two years of spring and autumn with cottonseed shell raw material crush indoor planted mushrooms, were good harvest. In the third year, cultivation will continue and pollution will occur. Each pollution, will remove the contaminated block to the outdoors; indoor cleaning, disinfection with lime water, and then the conventional method of raw material cultivation, the result is still a lot of pollution, most of the mold to have mildew. Description Gu Fang and the environment has been seriously polluted, it is difficult to raw material cultivation.
