Refined early warning technology for freezing damage of Jiangxi honey pomelo based on CMA-GD model
Meteorological grade index of pomelo freezing damage early warning was built by combining the freezing temperature index and meteorological index of freezing prevention measures.Then early warning experiment on the freezing damage of Jiangxi honey pomelo during the overwintering period in 2021 was carried out to analyze the feasibility of conducting hourly freezing damage warning of honey pomelo based on CMA-GD model by application of the intelligent grid forecasting product of CMA-GD model in Jiangxi Province to predict the hourly temperature of 2 m in the area.The results showed that the established meteorological level indicators for freezing damage of honey pomelo were consistent with the actual symptoms and degree of freezing damage of honey pomelo.The CMA-GD model based warning product for the freezing damage level of honey pomelo could accurately capture the changes in the occurrence and development of freezing damage 3 days in advance,and could provide technological support for initiating the warning of honey pomelo freezing damage,understanding the severity of honey pomelo freezing damage and the stage of occurrence and development of honey pomelo freezing damage in advance.
