摘  要：
为了比较香菇渣和平菇渣作为土壤改良剂还田对土壤的影响,进行了将不同比例的(25%,50%,75%)香菇渣和平菇渣分别添加到土壤中恒温培养100 d,每隔20 d测定其土壤中磷元素与钾元素含量的研究。结果表明:香菇渣和平菇渣作为土壤调理剂对土壤肥力有显著的改善作用,尤其对土壤中速效钾和全磷含量的增加,随着食用菌渣添加量的增加和培养时间的延长,速效钾和全磷含量呈现持续上升的趋势,说明食用菌渣对提高土壤速效钾和磷有明显效果;土壤中添加食用菌渣后还适当降低了土壤的pH值,从培养20 d时的pH=8.0左右下降到100 d后的pH=6.0左右。

摘  要：
To compare the effects of lentinus edodes residue and pleurotus ostreatus residue on soil fertility,the two residues were added into soil with different ratios(25%,50%,75%) to culture for 100 days in Constant temperature,and the amount of K and P were determinationed every 20 days.lentinus edodes residue and pleurotus ostreatus residue had obvious effects on the enzyme activities of soil as soil conditioners.Especially for the soil total P content and rapidly-available K increasing.Along with the increasing of adding amount of Edible fungus slag and the time extension of cultivate.It presented rising trend of rapidly-available K and total P content.It declared that edible fungus slag had obvious effect on improving soil rapidly-available K and P.It properly reduced the soil pH value after edible fungus slag adding in the soil.From pH=8.0 of 20d down to the about pH=6.0 of 100d later.
