黑木耳是我国传统出口商品,历来都是用段木栽培,由于段木资源减少,近年来不少耳产区的耳农采用木屑、棉子壳等为代料来生产黑木耳,节约了不少木材,但在非棉区、林区要发展木耳生产比较困难。为此我们因地制宜,以稻草为栽培黑木耳的主料,1992年至1993年6月先后进行了三次实验,取得了突破性的成功和良好经济效益。现简报如下: (一)品种选育 我们从国内12个科研单位和大专院校引进的一些黑木耳品种,通过品比试验筛选出了一个适应稻草原料栽培的高产优质、抗逆性强的菌株,定名为随丰一号。该菌株每百公斤稻草料可产干耳12～14kg。 (二)制生产种 培养料配方:①稻草80％,麸皮15％,过磷酸钙2％,石膏粉、红糖、食盐各1％;②稻草63％,棉子壳25％,麸皮、石膏粉、过磷酸钙各1％。pH均为6～7,料水比1:2,每100kg料内另加黑木耳专用肥2包(100g)。稻草要加工成2cm左右长。培养容器可用罐头瓶和17×35cm的塑料袋,装料后常压灭
Black fungus is our traditional export commodities, traditionally cultivated with segments of wood, due to the reduction of wood resources, in recent years a lot of ears of the ear area of agricultural production using sawdust, cotton seedlings and other materials to produce black fungus, save not Less timber, but in the non-cotton area, forest area to develop fungus production more difficult. To this end, according to local conditions, we used straw as the main ingredient of black fungus. From 1992 to June 1993, we conducted three experiments and achieved breakthrough success and good economic benefits. Now briefing as follows: (a) breed selection We from China 12 research institutes and tertiary institutions to introduce some black fungus varieties, through the ratio test selected a suitable straw rice cultivation of high yield, high resistance strains , Named as Feng One. The strains per kilogram of straw forage can produce dry ears 12 ~ 14kg. (B) of the system of production training materials Recipe: ① straw 80%, 15% bran, superphosphate 2%, gypsum powder, brown sugar, salt 1%; ② straw 63%, cotton seed shell 25% Gypsum powder, superphosphate each 1%. pH is 6 to 7, material to water ratio of 1: 2, plus 100 grams of black fungus special fertilizer per 100kg material (100g). Straw to be processed into about 2cm long. Culture containers available cans bottles and 17 × 35cm plastic bags, the pressure is normally off after loading
