菌袋质量的好坏,直接影响制种的成品率和经济效益。如有一个年产10万袋平菇栽培种的菌种厂,由于菌袋质量不好成品率下降15%,直接经济损失达1.6万元。目前我们用的菌袋其源料主要有高压聚丙烯和低压聚乙烯。高压聚丙烯薄膜透明度高,发菌期菌丝生长看得见,污染杂菌易识别,能耐1.5公斤以上压力,适
Bag quality is good or bad, a direct impact on seed production rate and economic benefits. If an annual output of 100,000 bags of mushroom cultivation plant species, due to the poor quality bags, yield 15% decline in the direct economic losses of 16,000 yuan. At present, the germ bags we use are mainly high-pressure polypropylene and low-pressure polyethylene. High-pressure polypropylene film, high transparency, fungal mycelium growth visible, easy to identify contaminated bacteria, resistant to more than 1.5 kg pressure, suitable
