蘑菇培养料须经发酵腐熟。有的菇农认为培养发酵腐熟程度越高越好,其实不然。如果腐熟过度，培养料营养成份大部分被微生物消耗，不能满足蘑菇对营养的需要。料中草茎失去弹性，通气性差，不利于蘑菇丝体的呼吸。培养料堆积挝大，会滋生大量的病菌和害虫，危害蘑菇生长发育。栽 Mushroom culture materials to be fermented maturity. Some mushroom farmers believe that the higher the degree of maturity of fermentation, the better, in fact not the case. If excessive decomposed, most of the nutrient material training material is consumed by microorganisms, can not meet the nutritional needs of mushrooms. Material stems in the loss of elasticity, poor ventilation, is not conducive to the mushroom body’s breathing. Cultivation of large piles of material, will breed a large number of bacteria and pests, endanger the growth and development of mushrooms. plant
