为了探索几个黑木耳菌株在稻草袋料栽培中的表现,笔者进行了此项试验.1 供试菌株与配方 ①菌株:黑木耳835、黑广、黑5、黑6、沪耳一号(CK).②培养料配方:切成3cm长的稻草38kg、麸皮10kg、过磷酸钙250g、硫酸镁100g、磷酸二氢钾150g、碳酸钙500g、红糖500g.2 试验方法 稻草浸水48小时后沥干至70%的含水量,再与其他辅料混合均匀,培养料含水量为65%,17×33cm的聚丙烯塑料袋装料,袋装量400g,每处理100~120袋.经高压灭菌1小时,取出冷至常温在无菌条件下接入参试菌种.菌丝满袋后1周,在袋的周围用刀片均匀划1cm长的口12处,然后将袋置于铺沙2~3cm厚的土上,袋间隔5~10cm,在袋上覆透明薄膜.当耳基形成约1cm大小时,每天向沙里渗水,并结合每天揭膜通风向袋周围喷水3~4次.耳片长成后逐潮采收考耳.
In order to explore the performance of several black fungus strains in the cultivation of straw bags, the author conducted this test.1 Test strains and formulations ① strains: black fungus 835, black wide, black 5, black 6, Shanghai ear on the 1st CK) .② training material formula: cut into 3cm long straw 38kg, bran 10kg, superphosphate 250g, magnesium sulfate 100g, potassium dihydrogen phosphate 150g, calcium carbonate 500g, brown sugar 500g.2 test method straw after 48 hours Drained to 70% moisture content, and then mixed with other excipients, the culture material water content of 65%, 17 × 33cm polypropylene plastic bags, bags 400g, each processing 100 to 120 bags. Bacteria 1 hour, remove the cold to room temperature access to the test strains under aseptic conditions mycelium full bag after 1 week, the knife around the bag evenly drawn 1cm long mouth 12, and then the bag placed in sand 2 ~ 3cm thick soil, the bag interval of 5 ~ 10cm, the bag covered with transparent film.When the ear base to form a size of about 1cm, seepage to the sand every day, combined with the daily Jiemo ventilation to the bag around the water 3 to 4 times After the ears grow into the tide to collect exam ears.
