Cottonseed hull substrates blended with different ratios of Castanea mollissima Blume shell were prepared and used for the cultivation of Pleurotus geesteranus. The effects of the chestnut shell content on the mycelial growth rate, yield, nutritional composition and contents of heavy metals of the cultivated Pleurotus geesteranus were investigated. The results suggest that the Castanea mollissima Blume shell in substrate can increase the mycelial growth rate, yield, biological efficiency and the contents of protein, crude fiber, amino acids and essential amino acids of Pleurotus geesteranus. Further investigation suggests that the tannin and saponin in Castanea mollissima Blume shell and the C/N ratio of substrate significantly influence the mycelial growth rate. The crude fat content of Pleurotus geesteranus decreased, while the contents of heavy metals including mercury (Hg), arsenic (As), cadmium (Cd) and lead (Pb) increased with the increase of the Castanea mollissima Blume shell content in substrate. Based on these results, the content of Castanea mollissima Blume shell was optimized to be less than 30% for the cultivation of Pleurotus geesteranus.
