分析测定了纸厂废渣、蘑菇废料和香菇废料等3种工农业废料的理化性状,并以这3种废料作覆土材料,研究其对蘑菇生长与产量的影响。结果表明,纸厂废渣、蘑菇废料和香菇废料的持水率分别为49.3%,43.8%和70.7%,均高于砻糠田土(33%),但低于泥碳(84.5%)。3种废料的电导率及pH值均高于砻糠田土和泥碳。香菇废料和蘑菇废料具有与泥碳相似的水分释放曲线,在1.7×104Pa的牵力下,香菇废料和泥碳的水分释出量相近,分别达87.25ml和92.35ml,而蘑菇废料的水分释出量相对较低,为58.25ml。纸厂废渣的水分释放曲线与砻糠田土相似。以这3种工农业废料作蘑菇覆土材料,蘑菇产量均明显高于以砻糠田土作覆士材料,增幅分别为11.7%,32.0%和21.1%。
The physical and chemical properties of three kinds of industrial and agricultural wastes such as paper mill waste, mushroom waste and mushroom waste were analyzed and analyzed. The effects of three kinds of waste materials on the growth and yield of mushroom were studied. The results showed that the water retention rates of pulp mill waste, mushroom waste and shiitake waste were 49.3%, 43.8% and 70.7%, respectively, which were higher than that of 砻-furrow soil (33%), but lower than that of peat (84.5%). The conductivity and pH value of the three kinds of waste materials were higher than that of 砻-furrow soil and peat. Mushroom waste and mushroom waste have the same moisture release curve as peat carbon. Under the pressure of 1.7 × 104Pa, the water released from mushroom waste and peat is similar, reaching 87.25ml and 92.35ml respectively, while the moisture content of mushroom waste The output is relatively low, 58.25ml. Paper mill residue moisture release curve and furrow soil similar. With these three kinds of industrial and agricultural waste as mushroom cover material, the yield of mushrooms were significantly higher than that of mulberry bran, with the increase of 11.7%, 32.0% and 21.1% respectively.
