Method for grafting pinus sylvestris and pinus koraiensis

Abstract

The invention discloses a method for grafting pinus sylvestris and pinus koraiensis. The method comprises the following steps of: selecting the planted live pinus sylvestris as a stock, and determining the specific grafting time according to the local temperature in the next year; selecting pinus koraiensis branches of over two thirds as scions, wherein the length of the scions is about 5 to 7 centimeters; performing grafting in a skin attached grafting manner, winding with plastic cloth after grafting, cutting the part above the pinus sylvestris scions after the grafted scions survive, unwinding the plastic cloth, rewinding, and unwinding the plastic cloth before the tree is revived in the next spring; and cutting the pinus sylvestris branches at the part of the live pinus koraiensis higher than the scions. By the method, the defect of danger during picking pinecones of the conventional common pinus koraiensis is overcome, the pinecones are grown in three years after grafting and picked in four years, and the grafted trees are short, abundant and convenient to pick and manage. The bred pinus koraiensis can be planted to the roadside or in gardens and used for greening.

Description

technical field [0001] The invention relates to a pine tree grafting method, in particular to a grafting method in which sylvestris sylvestris is used as a rootstock and Korean pine is used as an ear.

The cones are called pine cones, which are precious medicinal materials. Generally, the age of red pine trees is between 12 and 15 years. There are few towers connected to a Korean pine, usually four to six towers. And the tower is connected to the top of the tree seven to ten meters away, and there are no towers on the side branches. Twenty to thirty pagodas can only be reached when the tree grows for twenty to thirty years. Moreover, the trunk of such a red pine tree below five meters is basically free of pine cones. If you want to climb up the tree, you must use other aids such as l...
