Soil Disinfection Technology for High Temperature Closed Greenhouses in Panjin City in Summer
Through the reflecting issues of some farmers in Panjin city and long-term production research,it was found that the greenhouse planted by some farmers in Panjin city was extremely serious due to long-term continuous cropping and unscientific pest and disease control methods.Although local farmers used various prevention and control methods,it was still difficult to eradicate pest and disease in the greenhouse.To solve the production problem faced by local farmers,from 2022 to 2023,the Vegetable Research Institute of Liaoning Academy of Agricultural Sciences collaborated with local farmers to conduct soil disinfection experiments in summer high-temperature soaking greenhouses planted by farmers near the Caigentang training base in Panjin city.To enhance the prevention and control effect,different doses of lime nitrogen and 98％cotton foam particles were added to the experiment for different combination treatments.The experimental results showed that the soil disinfection effect of 35 g/m2 98％cotton long particles+135 g/m2 lime nitrogen high-temperature greenhouse was the best,but the soil disinfection and control effect and cost investment of 35 g/m2 98％cotton long particles+105 g/m2 lime nitrogen high-temperature greenhouse was most easily accepted by farmers.
