1974年我县开始人工栽培黑木耳,到去年年底,全县已办起32座木耳场,1座木耳菌种厂。现把我县各社队黑木耳人工栽培经验简单介绍如下。一、黑木耳对环境条件要求1、养料:黑木耳生长发育所需的养料,以碳水化合物和含氮物质为主,此外,还需少量无机盐类。2、水分:黑木耳需要大量水分才能生长发育。人工培育时,如锻木,在七、八成干时,空气相对湿度90-95%发育最快,耳丛大、耳肉厚。水份过多,会抑制菌丝生长或导致死亡。空气相对湿度在80%以下时,发育慢,肉薄、质硬。
County in 1974 began artificial cultivation of black fungus, to the end of last year, the county has set up 32 blocks of fungus, a fungus plant. Now I County County commune black fungus artificial cultivation experience is as follows. First, the black fungus on the environmental conditions 1, nourishment: Black fungus growth and development of nutrients required to carbohydrates and nitrogen-based substances, in addition, the need for a small amount of inorganic salts. 2, moisture: black fungus need a lot of water to grow and develop. Artificial cultivation, such as forging wood, in the seven or eight dry, the relative humidity of 90-95% of the fastest development, large ears, thick ear meat. Too much water can inhibit mycelial growth or cause death. Air relative humidity below 80%, slow development, thin meat, hard.
