1987～1989年,笔者承担了河北省科学院下达的食用菌增产剂研制课题。经两年多的研制试验,在10多个配方中筛选出冀微87—1增菇灵。以平菇、草菇为试验材料,在所内外进行了17批重复试验和多点示范,均取得了显著的增产效果,一般可增产30～40％,高者达70％以上,并可改善菇类的质量,提高丝氨酸、 From 1987 to 1989, the author undertook the research topic of edible fungus production increasing agent issued by Hebei Academy of Sciences. After more than two years of research and development trials, more than 10 formulations were screened Ji micro 87-1 by Mushroom Ling. With mushrooms and mushrooms as test materials, 17 batches of repeated tests and multiple demonstration were conducted both inside and outside, and significant yield increase was achieved. Generally, the yield could be increased by 30-40% and the highest by more than 70% Mushroom quality, improve serine,
