1.稻麦产区的菇农,常放弃当地丰富的稻、麦草资源,从外地购进价高的棉籽壳作培养料。为何舍近求远?因为稻、麦草种平菇常低产,甚至失败。究其原因,主要是稻、麦草含碳多氮少,营养不平衡;表面有一层蜡质,且硅酸盐含量较高,不利于平菇分解利用;弹性大、空隙多、吸水保水性差,影响平菇菌丝吃料; 1. Mushroom growers in the rice-wheat producing areas often abandon the abundant resources of rice and wheat straw in the area and purchase the cottonseed husk with high purchase price from other places for cultivation materials. Why close? Because rice, wheat straw mushroom often low yield, or even failure. The reason is mainly that rice and wheat straw contain less nitrogen and more nutrients, and the nutrition is not balanced; the surface has a layer of wax and the content of silicate is high, which is not conducive to the decomposition and utilization of Pleurotus ostreatus; the elasticity is large, Affect Pleurotus ostreatus eat;
