摘　　要：苹果日灼病是一种常发性生理病害,近年来在套塑膜袋果园发生严重,其主要原因是套塑膜袋苹果的果面温度较未套袋苹果提高4～5℃,气温骤升加速并加重其发病。采取避开气温骤升期套袋,并加强肥水管理,提高树势等措施,可使日灼果率降到2%以下。Apple sun scald is a frequently-occurred physiology disorder,and in recent years it's severe in the bagged-apple orchards.Its mechanism is that the temperature on the surface of bagged apples increases by 4～5℃ and has an accelerating-increase,and thus worsens the disease. It makes less than 2% of incidence of bagged apples that the time of accelerating increase in the temperature is avoided while bagging and increases fertilizer, moisture management and living capacity etc.
