Abstract:: To explore the effect of different protective treatment on winter hardiness of young sweet cherry cultivation,8 protective methods were used which could warm the trunk of 2-year-old sweet cherry trees,and then got a quick statistic about frozen injury after overwintering.The results showed that earth up+straw cover and earth up could alleviate the freezing damage effectively,the browning cold degree was the class I for the bark chinks of the trunk and phloem browning of branches,it respectively increased 30.16%,26.11% than CK,the germination rate of newborn branches was very significantly different,but the lowest rate of phloem browning was only 12% for earth up+straw cover among them;the browning cold degree for the bark chinks of the trunk about straw cover,earth up+felt were the class I,phloem browning just for class Ⅱ,it was significantly different for the germination rate of newborn branches;rest of them were all undesirable,such as plastic film,felt,coated white agent,lime water,the morphological indexes of frozen damage was more serious.The study showed that earth up+straw cover was better than earth up,but both of them could effectively improve the winter hardiness of young sweet cherry cultivation,it could be an applicative measure applicated in production.
