Abstract:
Bamboo-edible fungi intercropping has been widely reported to have significant economic benefits, but its effect on the ecology of bamboo forest and soil ecology is lack of research and evaluation. The edible fungi (
Stropharia rugosannulata and
Dictyophora indusiata) were intercropped under different types of bamboo forests (scattered, clustered and mixed bamboos) in the planting industrial park of Wugao Forest in Xuyong county. The changes of diameter at breast height, bamboo shoot quality, soil pH, soil organic matter, main nutrients, lignin and cellulose content of bamboo strips were determined and compared before and after intercropping. The results showed that the intercropping of edible fungi could promote bamboo growth, and facilitate the accumulation of free amino acids, soluble proteins and vitamin C in bamboo shoots. After intercropping, soil pH value and the available K content both increased, while the ammonium nitrogen content showed negligible variation or decreased to some extent. Meanwhile the nitrate nitrogen content increased, and the ratio of ammonium nitrogen to nitrate nitrogen decreased. The available P content only decreased significantly in the clustered bamboo forest, while the total N, P, K and organic matter content had almost no significant change. After planting the edible fungi (
Dictyophora indusiata), lignin and cellulose in bamboo stump degraded slightly faster. The present study can provide basic data for the evaluation of ecological effects and scientific management of bamoo-edible fungi intercropping model.
