覆土是蘑菇栽培中的一项花工多、劳动强度大的工作。为改革这项工艺,我们于1978年开始旧菌床覆土层再利用的尝试。本县有些公社已有较大面积推广,部分菇房已沿用三年了。实践证明,旧菌床土层的再利用,只要处理妥当,不会影响蘑菇产、质量,且比常规覆土节省工作日达60～70%。 (一)具体做法 1.旧床土的保存。事先把菇房门窗畅开,让床土层凉干约1周,再将床土逐层耙下(尽量少带菌料)聚集
Cladding is mushroom cultivation in a multi-labor, labor-intensive work. In order to reform this process, we started the attempt to recycle old soil coverings in 1978. Some communes in the county have a larger area to promote, some mushroom houses have been used for three years. Practice has proved that the old bacteria bed soil reuse, as long as properly handled, will not affect the mushroom production, quality, and save up to 60-70% of the work day than the conventional casing. (A) specific practices 1. Old bed soil preservation. Mushroom room doors and windows in advance to open, so bed soil dry for about 1 week, and then rake soil layer by layer (as little as possible with bacteria material) gathered
