Non-buried Cold-proof Overwintering Technology of Grape Cultivation in Cold Regions

Winter protection is a key link of grape cultivation in cold regions，but operation of burying soil has some disadvantages which restrict development of grape cultivation in cold regions.A non-buried cold-proof overwintering technology was put forward，and winter field test was carried out，results showed that the non-buried cold-proof overwintering technology could meet temperature requirement of winter grape in cold area，and installation and removal of cold proof facilities were simple，labor-saving and time-saving.
