Abstract: Abstract:Effects of grafting methods, height of stock, source of scion, the storage time of scion, and different date of graft etc on survival rate of axillary wildjujube were studied. In early March, while the height of stock reached 15～25 cm , one year eugenic shoots were selected as scion, which should be grafting as fresh as possible and should be grafted after being pared to reduce the exposure time in air, the joint of the scion and the stock were level and smooth, Thus, the grafting survival rate can reach 85% or more by cut grafting or side grafting. However, it is worth noting that Small plastic bags were set on the grafting seedling in order to water proof when grafting taken on rain day.
