Abstract:

In order to discuss the effect of edible fungi wastes long-term used in farmland, and to provide the basis of environmental impact assessment, this paper explored the influence of edible fungi wastes to soil physical-chemical properties and nutrient characteristics, by compared with different tillage periods soil (2, 3, 4, 6, 10 years) with application of edible fungi wastes continuously. The results showed that, the fertility of the soil had been greatly improved compared with uncultivated desert soil, but soil physical-chemical properties, organic C, N, P and K had different variation tendency under different tillage period, and salt content increased with tillage periods, as well as C levels, but K and P level maintain the same level between 2-6 years, with N levels decreased cultivation age. Soil salt content showed positive correlation with P, K and soil organic matter. The above results indicated that cultivation and land use and related irrigation profoundly affected desert soil under different tillage period with a application of edible fungi wastes.
