Method for grafting big juglans sigillata trees
The technology of iron walnut and walnut tree is applied in the field of grafting of large iron walnut trees, which can solve the problems of low grafting survival rate, no wax sealing of fringe collection, small contact area of cambium, etc., so as to improve the grafting survival rate and adaptability. And the effect of strong resistance and significant economic benefits

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;
[0039](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 a...
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 ...
