河北省科学院微生物研究所研究成功的棉籽皮袋栽黑木耳于1983年通过省级鉴定后,两年多来在本省示范推广,栽培350余万袋,成功率为90.2％,平均百千克料产干耳8.5千克,至1985年经济效益已达200余万元。如万全县1985年有1100户栽培黑木耳235万袋,产千耳5.88万千克,产值132.7万元,每个种植户平均收入达1206元。1986年已有一千多农户签订合同1300万袋,预计产值500万元;阳原县1985年有52户种木耳28万袋,产干耳5600千克,收入8万4千元,
Hebei Institute of Microbiology, Institute of Microbiology, successfully studied the black fungus bag after 1983 provincial-level identification, more than two years in the province to promote demonstration and cultivation of more than 350 million bags, the success rate of 90.2%, the average yield of 100 kg Ear dry 8.5 kg, to 1985, economic benefits have reached 200 million. Such as Wanquan County in 1985 1,100,000 cultivation of black fungus 2350000 bags, ear production 58,800 kilograms, the output value of 1327000 yuan, the average income of each growers amounted to 1206 yuan. In 1986, more than a thousand farmer households had signed 13 million bags of bags and the output value was estimated at 5 million yuan. In 1985, there were 52 kinds of edible fungus in Yangyuan County, with 280,000 bags of edible fungus and 5600 kg of dry ears, earning 84,000 yuan,
