[Objective] Soil quality improvement by recycling of fungus waste was researched to provide theoretical basis for the utilization of solid wastes produced by farming.[Methods] Field experiments were carried out in a rice-wheat rotation field in the Chengdu plain for one year. Of which five levels were designed including regular fertilizer(CF)

50% fungus waste recycling(T1)

100% fungus waste recycling(T2)

150% fungus waste recycling(T3) and 200% fungus waste recycling(T4). Soil samples from 0-15 cm

15-30 cm

30-50 cm soil layers were collected and soil nutrients were measured.[Results] (1) Either for fungus waste or regular fertilizer

full amount nutrients in 0-15 cm soil layer were significantly greater than that in 15-30 cm(p<0.05);(2) As compared with the regular fertilizer of no fungus recycling(CF)

the rice field experiment showed that TK and TN contents were improved in level T4; TP content was improved in the levels of T2

T3 and T4. The wheat field showed that

TN content and TP content were increased under T4 level; Levels of T1

T2

T3

T4 had higher but not significant TK content in contrast with the values of regular fertilizer(p<0.05);(3) Soil nutrients content increased as the fungus waste recycling levels increased(T1

T2

T3

T4).[Conclusion] Contents of TN

TP and TK can be improved when high level of fungus is recycled as fertilizer; TP content can be increased when medium level of fungus is recycled.
