摘要： A novel hyperthermophilic compost (HPC) produced from fast hyperthermophilic composting of 24 h was evaluated as a partial substitute of conventional compost (COM) and inorganic fertilization (CF) on Chinese cabbage (Brassica campestris ssp. chinensis) and chili pepper (Capsicum annuum L.) during field experiments under two soil systems. Compost characteristics were related to plant growth and soil fertility. In Anthrosols, the highest crop yield and nutrient uptake were obtained from the HPC or COM, although crop yields did not significantly (P > 0.05) differ from the yields of CF-treated soils. In the less fertile Fluvisols, crop yields were significantly higher in HPC and COM treated soils than CF treatment. Application of HPC and COM increased dissolved organic carbon (DOC), total nitrogen (N), available phosphorous (P-av.) and available potassium (K-av.) by 23.1%, 6.1%, 55.3%, 17.4%, respectively in Fluvisols and 28.1%, 5.5%, 43.8%, 34.3%, respectively in Anthrosols compared to CF. HPC amendment increased soil bacterial populations by 19 and 8-fold and fungal populations by 1912 and 9-fold in Fluvisols and Anthrosols, respectively. Chinese cabbage yield was positively correlated to TN, NO3-, P-av. and exchangeable Ca and chili pepper yield was positively correlated to TN and NO3-. It is concluded that organic amendments had strong potential to improve soil organic carbon, soil nutrient status, crop yield and microbial activity in Fluvisols and Anthrosols in Tai-Lake region of China. The beneficial results of HPC in soils and crop could reduce the use of mineral fertilizer for the sustainable production of vegetables.
