In order to reveal the effects of edible fungus residue on vegetation

soil organic carbon and enzyme activities of sandy soil

sandy soil was sampled in the northwest Sichuan as research object by five point sampling method. The results showed that the treatment of mixing 5 kg/m2 edible fungus residue in soil (F1)

mixing 10 kg/m2 edible fungus residue in soil (F3) and mixing 15 kg/m2 edible fungus residue in soil (F4) could significantly increase vegetation coverage and height

and decrease the soil bulk density. Compared with CK

the treatment of F4 increased vegetation coverage and height

soil physicochemical properties and enzyme activities. The treatment of F2 could increase soil organic carbon

amylase

invertase and polyphenol oxidase activity compared with the CK

but it was significantly lower than F1

F3 and F4. This result indicated that the effect of cover the soil was better than that of edible fungus residue mixed application. Correlation analysis showed that the SOC

below biomass and enzymes activities were obviously positive correlation（P<0.01）.
