In recent years, Zunhua City Forestry Bureau seedling station nursery with acacia as rootstock grafted Jiangnanhuai, split, abdomen, cutaneous access to the three methods were compared to the best results to plug the skin, the survival rate of 95 %the above. First, the scion storage and dipped wax stopped growing in Jiangnanhuai, before the flow of sap can be ear. Spike rough 1 cm above, longer than 20 cm. After scooping, leeward leeward to choose 1 meter deep, 1 meter wide and long as the number of scion pit, floor shop 20 cm thick wet sand, wet sand to the hand grip can not water for the degree. Put a layer of scion on the sand each level, put a layer of wet sand, the top layer of scion 20 cm from the pit, cover the pit to the pit on the 5 cm.
