黑木耳的食用及药用价值都很高,但过去生产一直以椴本为原料培养,这不仅产量低且周期长,又消耗大量木材。近两年来,我校生物兴趣小组以稻草为原料,瓶栽黑木耳,并获成功。原料为稻草66％(铡成寸长)、米糠32％、水200％、过磷酸钙1％、石膏粉1％。将碎稻草装袋称重浸水3—4小时,捞出,按比例加入米糠、石膏粉等充分混匀,手握此料见指缝有水不下滴即可。装 Black edible fungus has high edible and medicinal value, but in the past production has been cultivated with linden as raw material, which not only has low yield and long period, but also consumes a large amount of wood. In the past two years, the bio-interest group of our school took straw as raw material and used black fungus to make bottles for success. Raw materials for straw 66% (铡 into inch long), rice bran 32%, water 200%, superphosphate 1%, gypsum powder 1%. The broken straw bag weighing 3-4 hours immersion, remove, add rice bran in proportion, gypsum powder, etc. fully mixed, holding the material see the finger can not drop the water drops. Loaded
