草菇喜高湿,保证培养料中水分充足,是高产的基础。传统工艺要求培养料含水量为65%～70%,相当于加水量150%～190%,实际上供水不足,这是生产上草菇产量低的一个重要原因。本试验结果是,加水量由180%提高到220%～300%均能显著提高产量,其中以220%产量最高,生物学效率达32.8%,比加水量180%增产了36.72%。 Straw mushroom hi high humidity, to ensure adequate water culture materials, is the basis for high yield. The traditional process requires that the water content of the culture material is 65% -70%, which is equivalent to 150% -190% of water addition. In fact, the water supply is insufficient, which is an important reason for the low yield of mushroom production in the production. The results showed that the increase of water content from 180% to 220% ~ 300% could significantly increase the yield, of which the highest yield was 220%, the biological efficiency was 32.8% and the yield was 36.72% more than that of water added 180%.
