Abstract:
Eight cultivars of sweet cherry were used as materials.The cold injury of some sweet cherry cultivars after the twice cold wave were investigated in Tai′an city in November 2015 and January 2016.The results showed that the causes of cold injury ware were the cooling rate，long duration of low temperature and poorly protective consciousness，eventually leading to severe cold injury occurr on flower buds and branches.The cold injury index of the sweet cherry flower buds in some areas was as high as 79.9，and cold injury index of the branches was as high as 61.2.But the cold injury degree among different rootstock and cultivars were different.Finally put forward the frost prevention measures of sweet cherry including reasonable pruning，strengthen water and fertilizer，strengthen the flower and fruits，frozen parts processing，preventing ‘cold spell in later spring’ were able to prevent cold injury of sweet cherry.
