Abstract:

In recent years, in order to ensure vegetable supply and improve vegetable planting efficiency, greenhouse vegetables have been rapidly developed and applied. However, due to unreasonable fertilizer and water management, unscientific cropping arrangements, continuous cropping obstacles of pepper in greenhouses have been increasing year by year, which was the most common in the western Zhejiang region. By setting up flooded greenhouses, soil conditioners, microbial composite agents 1, 2, soil conditioner+microbial composite agent 1, and soil conditioner+microbial composite agent 2 in areas with severe continuous cropping of pepper in greenhouses, the effects of different treatments on the control of continuous cropping obstacles of pepper in greenhouses were studied. The results showed that the treatment of adding microbial composite agent 2 had achieved the best effect on preventing and controlling continuous cropping obstacles of pepper in greenhouses, with a diseased incidence rate of 2.2%. Besides, the 667 m² yield of peppers was 28.3% higher than that of the control group, with the output value increased by 3 456.3 yuan per 667 m² compared with the control, and the net income increased by 2 426.3 yuan per 667 m² compared with the control. Therefore, microbial composite agent 2 can be appropriately applied on continuous cropping of pepper in greenhouses.

Key words: pepper, microbial agent, yield, continuous cropping obstacle
