First, select the scion should choose strong growth on the robust stalks, winter buds full of branches, it is best to use with mining. Winter buried Manchu pruning in winter, the scion to go through the sand reservoir. Second, the grafting period but also because after the set of plastic bags, bag temperature rises faster than the atmospheric temperature, so to start early flow of liquid is appropriate. Third, cut a scion cuttings to retain a winter bud, stay in the winter buds on a 1.5 ~ 2cm flat cut, bud does not stay 4.5cm branches
