Regular soil testing is essential to promptly identify and address any issues. Next, during the land clearing phase, it's crucial to clean and disinfect the soil, using either 848 disinfectant at a 200-fold dilution or sterilizing agent at a 1000-fold dilution to thoroughly spray the ground. During the seedling bed stage and throughout the planting process, paying close attention to soil and environmental cleanliness is particularly important. For instance, after pruning and removing suckers during the planting process, it's necessary to promptly remove the cuttings, diseased plants, and pathogens from the greenhouse. Additionally, diseases often thrive in acidic soil, so it's important to monitor soil pH levels and make appropriate adjustments. Acidic soils can be treated with approximately 60 kilograms of quicklime per mu to alter the living environment of harmful microorganisms and inhibit the occurrence of soil-borne diseases.

Poor soil quality not only severely affects the growth and yield of vegetables but also leads to many persistent soil-borne diseases. We must understand the characteristics of good soil and maintain the quality of greenhouses in an optimal state.
