摘　　要：对林菌间作林内的微生态环境因子进行了观测和分析,探讨了林下栽培食用菌对二者生长的影响。结果表明:间作地行间光照强度日变化规律与对照一致,春季林内的日平均光强为35.46%,夏季降低为5.54%,秋季有所升高,为14.23%。间作地地面温度和空气温度的变化规律与光强一致,空气相对湿度的变化与光强和地温的变化相反。林菌间作林木与食用菌可互相促进生长,提高食用菌产量和林木出材量。The micro-ecological factor＇s day-changing character inside the intercrop woods were observed and analyzed. The result indicated that light intensity day-changing character and regularity in the intercrop woods was consistent with the CK, the day average light intensity was 35.46 percent in spring, that was reduced to 5.54 percent in the summer, the number raised to 14. 23 percent in the autumn. The ground temperature, air temperature＇s changing regularity were consistent with the light intensity changing. However, the air relative humidity＇s changing regularity was opposition with the changing of light intensity and ground temperature. Poplus-fungus intercrop was helpful to each other＇s growth, it could promote the fungus＇yield and the tree＇s timber amount.
