Abstract

In order to enhance the environmental adaptability of Salix×aureo-pendula CL.,using salix aureo-pendula as scion,the factors affecting the survival rate of grafting such as rootstocks,grafting time,grafting method,scion thickness,moisturizing treatment were all studied to screen the most suitable grafting method.The results showed that:salix×chuibaonica CL ’109’ was the best stock with highest survival rate(96%),followed by weeping willow(80%).The best grafting time was at the early April in the spring,the survival rate was more than 90%.The best grafting method was bark graft(93.3%).The appropriate scion thickness was 0.8 cm,and using plastic bag full closure was the best moisturizing treatment.
