采集分离野生黑木耳菌株98个,经过驯化与筛选,选育出优良菌株Au053。经与南方地区主栽品种新科1号、新科5号、Au139两年五个点的区试比较,以Au053表现最好,比新科1号增产9.7%,比新科5号增产10.0%,比Au139增产10.3%;遇高温高湿气候,2个对照菌株普遍发生严重的流耳、烂袋现象,而Au053不发生流耳、烂袋,稳定性较好。
A total of 98 strains of wild black fungus were isolated and collected. After domestication and selection, the excellent strain Au053 was bred. Compared with the regional trial of Xinke No.1, Xinke5 and Au139, two cultivars in southern China had the best performance in Au053, the yield was 9.7% higher than that of Xinke 1 and 10.0% higher than that of Xinke 5, Yield 10.3%. In the case of high temperature and high humidity, the two control strains commonly suffered from serious ear and rotten bags, while the Au053 did not have the ear and rotten bag. The stability was good.
