一、概述寨沟位于湖北省房县土城公社吊桥大队。土城公社属山区,历史上少雨多旱,干旱时因木耳缺水,空气干燥、黑木耳生长出现“间歇”,夏季如遇41℃的高温,黑木耳菌丝死亡木耳无收。1981年以前,该公社黑木耳平均架产2斤多,最高不到5斤。据对栓皮栎木耳化验分析,一架耳木(长1米、直径8～10厘米的耳木50根,)所含营养物质,可产黑木耳50斤,黑木耳的增产潜力很大。
First, an overview Zhaogou is located in Hubei Province Fang County Tucheng commune drawbridge brigade. Tucheng commune is a mountainous area, the history of rainy and more drought, dry arid lack of water due to fungus, air dry, black fungus growth appears “intermittent”, in summer case of 41 ℃ high temperature, black fungus mycelium death agaric. Before 1981, the commune black fungus average shelf yield 2 pounds, up to less than 5 pounds. According to the analysis of cork oak ears, one ear of wood (1 meter long, 8 to 10 centimeters in diameter, 50 pieces of ear wood) contains nutrients that produce 50 grams of black fungus. The yield of black fungus is very high.
