Problems solved by technology

[0005] At present, the traditional grafting technology still has the following problems: one is that the traditional grafting is generally carried out when the tree body germinates in the beginning of spring, and the grafting is now carried out. It is conducive to the water transportation of the rootstock, resulting in a low survival rate of grafting; second, the traditional scion collection is not wax-sealed, resulting in dehydration and death of the scion; The high content of substances such as interface tannin and the lack of oxygen in the process of callus formation lead to low survival rate of grafting; the fourth is that traditional grafting methods mostly use split grafting, and the contact area between rootstock and scion is small, which is not conducive to callus Tissue formation, resulting in a low survival rate; fifth, the traditional method does not injure and discharge water at the lower part of the tree, which causes wounds and flow accumulation at the grafting interface, which is not conducive to survival; sixth, the traditional grafting method does not leave pumping branches and has no transpiration pull. , causing the grafting interface to dry out and lack water, and the survival rate is low

Embodiment 1

[0030] (1) During the dormant period of the walnut tree (middle and late January), the developed branches of the high-yield, stable yield, strong stress resistance, and suitable for local development are cut from the mother tree as spikes. It is required that the appearance is smooth and straight, the internodes are long, full and fat, the degree of lignification is high, the pith core is small (the pith heart rate is about 20%), and the buds are full. Then put it in a cool and ventilated place until the moisture content of the cuttings is 80%. Carry out wax seal at the same time, wax seal is that beeswax and paraffin are heated and dissolved according to mass ratio 1:9, then carry out wax seal to fringe bar at 90 ℃, the fringe bar after wax seal is naturally cooled and placed in a cool place for subsequent use;

[0031] (2) During the budding and leaf-expansion stage (before and after the beginning of spring) of the iron walnut tree with strong tree growth and no pests and dis...

Embodiment 2

[0038] (1) During the dormant period of the walnut tree (middle and late January), the vegetative branches of the high-yield, stable yield, strong stress resistance, and suitable for local development are cut from the mother tree as spikes. It is required that the appearance is smooth and straight, the internodes are long, full and fat, the degree of lignification is high, the pith core is small (the pith heart rate is about 20%), and the buds are full, and then placed in a cool and ventilated place until the moisture content of the cuttings is 85%. Carry out wax seal at the same time, wax seal is that beeswax and paraffin are heated and dissolved according to mass ratio 1:9, then fringe bar is carried out wax seal at 80 ℃, the fringe bar after wax seal is naturally cooled and placed in a cool place for subsequent use;

Embodiment 3

[0046] (1) During the dormant period of the walnut tree (middle and late January), cut the developing branches of small walnut trees or the vegetative branches of large trees with high yield, stable yield, strong stress resistance and suitable for local development from the mother tree As spikes, the spikes should have a smooth and straight appearance, long internodes, full and fat, high degree of lignification, small pith (the pith heart rate is about 20%), and full buds, and then placed in a cool and ventilated place until the spikes Wax sealing is carried out when the moisture content of the water content is 75%. The wax sealing is to heat and dissolve beeswax and paraffin at a mass ratio of 1:9, and then wax seal the cuttings at 85°C. After wax sealing, the cuttings are naturally cooled and placed Store in a cool place;

[0047] (2) During the budding and leaf-expansion stage (before and after the beginning of spring) of the iron walnut tree with strong tree growth and no ...

Abstract

The invention discloses a method for grafting big juglans sigillata trees and belongs to the technical field of cultivation of agriculture and forestry. The method comprises the following steps: selecting excellent varieties, collecting scions, sealing wax and preserving scion woods, determining grafting time, selecting big juglans sigillata trees, selecting grafting branches, selecting water extracting branches, processing grafting unions, cutting the scions, grafting, draining water of the grafting unions, scratching the lower parts of the big trees and discharging water, and managing after grafting. By virtue of the method, the grafting survival rate of the big juglans sigillata trees reaches over 94%; the high yield can be achieved in three years after grafting; the method is applied and popularized for improving the big juglans sigillata trees, improving low-yield forests in walnut and fruiting walnuts in advance; the method has remarkable economic benefits, ecological benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of agriculture and forestry cultivation, and in particular relates to a method for grafting large iron walnut trees. Background technique [0002] Walnut (Juglans. spp) It is an important nut and woody oil tree species in my country. With the rapid development of my country's economy and the continuous improvement of people's living standards, urban and rural residents have more and more demand for walnuts, and production is far from meeting their needs. [0003] The large iron walnut trees in Yunnan are widely distributed, with a large number, low yield, poor quality and low economic benefits, which have seriously affected the rapid development of walnut production. Through the transformation of iron walnut forest, its economic value can be significantly improved, and farmers' income can be increased. It is an important means for farmers in mountainous areas to get rid of poverty and become rich. [0004...
