黑木耳是一种喜湿性菌类,在子实体生长发育阶段,不仅需要潮湿的环境,同时基质内还需含有足够的水分,才能保证正常的生长。我们采用塑料泡沫做床垫,进行袋栽黑木耳水分管理试验,从开洞至采收结束的2个月,平均每袋产鲜耳356.9克,折干耳35.6克,最大朵直径达18厘米,重98克。生物效率为71.4％,比挂袋栽培增产30.3％。现将试验方法及结果分析如下: Black fungus is a kind of hygroscopic bacteria, in the fruiting body growth and development stage, not only the need for humid environment, while the matrix needs to contain enough water to ensure normal growth. We use plastic foam as mattress to conduct bagging black fungus moisture management test, from opening to harvest the end of 2 months, an average of 356.9 grams per bag of fresh ears, folding ears 35.6 grams, the largest diameter up to 18 cm , Weighs 98 grams. Biological efficiency was 71.4%, increased by 30.3% than the bag cultivation. The test methods and results are as follows:
