Method for reducing high-temperature heat damage in flowering-filling stage of wheat

The invention belongs to the technical field of wheat cultivation, and particularly relates to a method for reducing high-temperature heat damage in the flowering-filling stage of wheat, which comprises the steps of uniform sowing of wheat, water and fertilizer management and chemical regulation. The water and fertilizer management comprises base fertilizer application, jointing fertilizer application, flower raising fertilizer application and water application; the base fertilizer comprises 15 kg/mu of diamine and 7.5 kg/mu of urea; the jointing fertilizer comprises 10.5 kg/mu to 12 kg/mu of diamine and 6 kg/mu to 7.5 kg/mu of urea; the flower raising fertilizer comprises 3 to 4.5 kg/mu of diamine and 1.5 to 2.25 kg/mu of urea; the chemical regulation and control comprises the steps that according to weather prediction and forecast, if the temperature is larger than or equal to 38 DEG C in the early stage of wheat filling, a chemical control agent is sprayed on leaf surfaces 7-21 days after flowering.
