段木栽培香菇、木耳等木生食用菌,采用木屑菌种,接种后每个穴都必须盖上大小厚薄适合的树皮盖或涂上特制的封蜡(石蜡4份、松香1份),以保护菌种。制作树皮盖既花工,又浪费段木;配制封蜡成本高,如果穴周围的树皮潮湿,封蜡便粘不上,且在干旱时封蜡易碰碎,故不太保险。日本已研制出碎屑基塑料盖(以木栓颗粒加酚醛树脂或尿醛树脂,热压而成)、泡沫塑料盖等;国内也有用木屑加细泥混合物来代替树皮盖的。笔者在比较树皮盖、封蜡、塑料盖的优缺点后,研制出一种成本较低、使用方便的新型密封材料,现介绍如下。
Section wood cultivation mushrooms, fungus and other woody mushrooms, the use of sawdust species, after vaccination each hole must be covered with the appropriate size bark cover or coated with a special sealing wax (paraffin 4, rosin 1) To protect the species. Making bark cover both flower workers, but also waste section wood; preparation sealing wax high cost, if the bark around the hole damp, wax seal will stick, and in the dry seal wax easy to break, it is not too safe. Japan has developed a detritus-based plastic cover (with cork particles plus phenolic resin or urea formaldehyde resin, hot pressing), foam cover, etc .; also useful wood shavings plus fine mixture of mud instead of bark cover. After comparing the advantages and disadvantages of the bark cover, sealing wax and plastic cover, the author has developed a new type of sealing material with lower cost and convenient use as described below.
