草炭在双孢蘑菇沙壤土覆土中的应用研究

Study on the Application of Peat in Sandy Loam Soil at Overlying Soil of Agaricus bisporus

以草炭和沙壤土为覆土材料,‘As2796’双孢蘑菇为试材,研究了双孢蘑菇沙壤土覆土中添加不同比例草炭对双孢菇生长的影响。结果表明:沙壤土中添加25%和50%的草炭作为双孢蘑菇覆土材料综合性状表现较好,覆土的持水率达到34.6%以上,理化性状得到改善,覆土层菌丝生长健壮,商品性好,产量高,效益好;4潮菇产量达到12.38kg/m2以上,纯收入达到86.42元/m2。

Taking the peat and sandy loam soil as covering materials,with Agaricus bisporus ＇As2796＇ as material,the effect of different proportions of peat in sandy loam soil as overlying soil on the growth of Agaricus bisporus was studied.The results showed that the sandy loam soil containing 25% and 50% peat had a better comprehensive characters performance.Its soil water holding rate reached more than 34.6%,the physical and chemical properties improved;the mycelium of overlying soil grew well,with good commodity nature,high yield and good benefits;the fourth tide mushroom production reached 12.38 kg/m2,net income reached 86.42 yuan/m2.
