In order to prove that the function of the brewing heat products of the active ventilation brewing heat supplementing system as the substrate material is not lower than that of the fermentation substrate purchased in the market，straw and cow dung with a volume ratio of 3∶1 were used as raw materials to carry out active ventilation high-temperature aerobic composting for a period of 60 days in this experiment.The aerobic composting products were mixed with the purchased substrates at a volume ratio of 100%(T1)，33.3%(T2)and 0%(CK)，and the growth and development of tomatoes under different substrates were compared.This study aimed to explore the feasibility of active ventilation high temperature aerobic compost as tomato growth substrate，and provide theoretical support for the matrix utilization of the products of active ventilation brewing heat.The results showed as follows:(1)The plant height and stem diameter of tomato cultured with T2 compound matrix were significantly better than those of CK and T1；(2)The photosynthetic rate of T1 was higher than that of T2，but the net photosynthetic rate of T2 was significantly higher than that of T1，which was 28.25 μmol/(m2·s)；(3)The yield of T2 tomato was 4.78 kg/plant，43.3% higher than CK and 13.7% higher than T1.Based on the comprehensive analysis of the above indexes，compost products under the condition of active ventilation brewing heat can be used as the cultivation substrate.Among them，active ventilation brewing heat products with volume ratio of 33.3% mixed with the market purchased matrix as the compound matrix had the best effect on growth of tomato plants.
