[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.
