我站从79年开始试验生料制蘑菇二、三级种,收到了较好的效果。此法可以节省草料堆制发酵的工序,简化操作。实践应用表明,生料未经堆料,碳、氮损失少,后劲足,菌丝生长强壮,在夏、秋季能忍受33～35℃高温的袭击,菌丝不易萎缩、老化。用生料二级种扩接三级种,以及在大床栽培上,菌丝恢复快,吃料快,试种单产达1.5斤/尺~2以上。现将几种生料的制种法简介如下:
From 79 stations, I started experimenting with second and third grade raw mushrooms and received good results. This method can save the fermentation process of heap compost, simplifying the operation. Practical application shows that the raw material has no material loss, less carbon and nitrogen loss, sufficient stamina and strong mycelial growth. It can withstand the high temperature attack of 33-35 ℃ in summer and autumn, and the mycelia hardly shrink and age. Second grade raw materials with three species of expansion, and in the big bed cultivation, mycelium restore fast, eat fast, try planting yield of 1.5 kg / ft ~ 2 above. Now several kinds of raw materials, seed production method is as follows:
