黑木耳代料栽培由于极易污染杂菌,因而生产发展不快。近两年来,盐城市有不少菇农和菌种场试种黑木耳,多数因杂菌污染而失败。我们经过两年多的探索,在袋栽黑木耳防杂菌污染技术方面取得了较好效果。1987年6月8～20日,共生产1120袋(17×33厘米聚丙烯袋),其中青霉和水霉污染的仅32袋,没有出现链孢霉污染。菌丝50～55天发到袋底,成品率97%。其中污染杂菌的29袋重新灭菌接种,发菌正常,实际只报废3袋。现将防污技术要点简介如下:发菌栽培期避开高温梅雨季节我地区袋栽黑木耳一般都安排在7月中旬,此时正值梅雨高温期,空气湿度常达90%左右,气温有时达32～34℃,杂菌污染率高,一旦发生链孢霉污染,很可能导致绝收(?)椐我们试验(?)秋耳袋栽可提早到5
Black fungus substituting cultivation because of extremely easy to pollute, so the production of unpleasant. In the past two years, there have been many mushroom growers and field trials of black fungus in Yancheng City, most of which failed due to contamination by bacteria. After more than two years of exploration, we have achieved good results in the anti-bacterial contamination of black fungus bags. Between June 8 and June 20, 1987, a total of 1120 bags (17 × 33 cm polypropylene bags) were produced, of which only 32 bags were contaminated with penicillium and water-borne molds and no molds were found. 50 to 55 days mycelium sent to the bottom of the bag, the finished product rate of 97%. Among them, 29 bags of contaminated bacteria were sterilized and inoculated. The germs were normal and only 3 bags were actually scrapped. Antifouling technology now briefings are as follows: Hair culture to avoid high temperature during the rainy season I planted bagged black fungus are generally arranged in mid-July, when the meiyu high temperature period, the air humidity is often up to 90%, the temperature is sometimes Up to 32 ~ 34 ℃, the high rate of bacterial contamination, in the event of fungal contamination with penicillium, is likely to lead to absolute failure (?) 椐 we test (?)
