specific Embodiment

[0020] Grafting time, in June-July, cut off the thick-dried compound leaf maple at a height of 2-2.5m with the main trunk diameter 3-10 cm thick as rootstock, and intercept the middle-growing and well-developed branches of the golden-leaf compound leaf maple crown. As a scion, remove the leaves immediately and leave the petiole. Each scion has 5 to 6 pairs of buds. The scion is about 15 cm long. The top of the scion is wrapped with a film to prevent moisture from evaporating. The lower end of the scion is cut into a wedge shape with a length of 1.5 to 2 cm, and the cut surface is smooth. Adopt the method for grafting in the grafting, scion is grafted on the rootstock, then is tied up with the plastic film that thickness is 0.04mm and width is 4-5cm. Shorten the rootstock, split the rootstock, cut the scion strips, insert the scion into the cortex of the rootstock, and use adhesive tape or packing rope to bind and fix the skin-inserting grafting method. During the grafting proc...

Abstract

The invention discloses a top grafting and head changing method for compound leaf maple summer green branches. The method includes the steps that in June and July, the portion, with the height of 2-2.5 m, of a compound leaf maple with the trunk diameter at the breast height of 3-10 cm is cut to form a stock, and annual shooting branches which are located on the periphery of a crown of a gold leaf compound leaf maple, are moderate in growth vigor and develop fully are cut to serve as scions, wherein the branches are 0.8-1.0 cm thick, and leaves on the branches are removed immediately while petioles are left; each scion has five to six pairs of buds and is 15 cm long, and the upper portions of the scions are wrapped by plastic films which are 0.04 mm thick and 4-5 cm wide; the lower end of each scion is cut into a wedge which is 1.5-2 cm long, the cut faces are smooth, the scions are grafted to the stock by adopting a bark grafting method in scion grafting, then the grafted scions are bundled through plastic strips. The method is simple, scientific and reasonable, production and implementation are easy, the scion fixing effect is good, the survival rate is large and can be over 95%, and the method is safe, reliable and beneficial for rapid propagation and crown forming performance of the compound leaf maples, and increases the production value.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for grafting and replacing heads of the summer green branches of the maple compound leaf. Background technique [0002] Golden leaf maple, yellow leaves, cold resistance, heat resistance. It is an excellent color-leaved tree species suitable for planting in both the north and the south. In the past, tree height replacement can only be carried out during the dormant period of the trees, and it is appropriate for the trees to germinate in spring, which is generally from late March to early April in Beijing. And spring is the busy season for farming, so labor arrangements are difficult. The time available for grafting is short. Due to time constraints, often a lot of grafting work cannot be carried out. Contents of the invention [0003] The purpose of the present invention is to provide a method for grafting and replacing heads of high green branch...
