利用稻草栽培平菇,可以缓解棉壳紧缺的矛盾,且稻草资源丰富,价格低廉,可提高经济效益.但用稻草栽平菇,采用常规法生物转化率一般只有45～60%,如采用以下五要诀,生物学效率可达120～150%.(一)要选择和处理好培养料稻草要干燥无霉变,色泽金黄,最好是糯稻草和早稻草或隔年稻草.并经过处理:①曝晒1～2天,以杀死部分粘附在稻草表面的病菌和虫卵.②用1～2%的石灰水浸泡1～3天,以去掉表面的蜡质达到软化,进一步灭菌、杀虫.③将浸过石灰水的稻草用清水冲清后上堆发酵,使堆温达60℃以上,其间翻堆一次.经处理的稻草,质地柔软,病虫害少,含水量适宜,播种后利于发菌.
The use of straw cultivation of Pleurotus ostreatus, can ease the contradiction of shortage of cottonseed, and rich straw resources, low prices, can improve economic efficiency.But the use of straw mushroom cultivation, the conventional method of biological conversion rate is generally only 45 to 60%, such as the use of the following Five tips, the biological efficiency of up to 120 ~ 150%. (A) to choose and handle culture straw should be dry and mildew-free, golden color, preferably glutinous rice and straw or rice every other year. Exposure to 1 to 2 days to kill some bacteria and eggs attached to the surface of the straw ② soaked with 1 to 2% lime water for 1 to 3 days to remove the surface wax to soften, further sterilization, killing Insects.③The straw soaked in lime water after rinsing with water rinsed on the heap fermentation, so that the temperature reached above 60 ℃, during the turn pile once treated straw, soft texture, less pests and diseases, water content, sowing benefit Hair bacteria.
