膨体珍珠岩质地松软,蓄水和透气性能好,从理论上来讲,香菇压块中添加少量膨体珍珠岩,对改善栽培块的物理性状可能有一定作用,但对菌丝生长有无不利影响未见报道。为此,我们于1985年进行了本项试验。 The bulky perlite is soft in texture and has good water storage and permeability. Theoretically speaking, the addition of a small amount of expanded perlite into the mushroom briquette may play a role in improving the physical properties of the cultivation block, but there is no adverse effect on the mycelium growth No impact has been reported. To this end, we conducted this test in 1985.
