莜麦秸秆营养成分测定及双孢菇栽培试验

Determination of Naked Oat Straw Nutrients and Cultivation Test of Agaricus bisporus

以莜麦秸和双孢菇为试材,研究莜麦秸作为双孢菇栽培主料的可行性。结果表明:莜麦秸秆基本成分适合双孢菇菌丝的分解利用,莜麦秸1 500kg、干牛粪1 125kg、尿素15kg、过磷酸钙50kg、石膏25kg和石灰25kg为适宜双孢菇栽培的培养料配方。与双孢菇栽培常规培养料进行对比发现,莜麦秸栽培主料发菌速度快,菌丝生长势好,其菌丝产量与稻草主料的接近,高于以麦秸主料。从农艺性状来看,莜麦秸培养料子实体菌盖较小,菌柄长度、菌盖厚度和单菇重中等。综合来看,在莜麦产区,莜麦秸可作为双孢菇栽培新原料。

With the straw of oat （Arena nuda） as the major culture materials and Agaricu bisporus as fest material,the practica bility of the oat straw that was suitable for the mycelium of Agaricu bisporus was studied. The results showed that, the suitable recipe of culture materials for Agaricu bisporus was：oat straw 1 500 kg,dry cow dungs 1 125 kg,urea 15 kg, superphosphate 50 kg, gypsum 25 kg and time 25 kg. Compared with the other two common major culture materials,the mycelial grew faster for the new major culture materials,and the yield of the fruiting body was comparable with that for the rice straw but higher than that for the wheat straw. For the agronomic traits,the cap thickness,stipe length and single mushroom weight were moderate for the oat straw material. Collectively, the oat straw was suitable for sustainable cultivation of Agaricu bisporus.
