The grafting time of orange trees is generally in spring, usually before or just after germination. If the bud has grown out and the length exceeds 1 cm, the success rate of grafting will be greatly reduced. At the same time, it should not be carried out in rainy days. Rainwater is easy to breed bacteria, making it impossible to survive.

Second, scion treatment

Select several branches of the orange tree, cut off the buds on the branches and keep a little xylem. Leave an inclined plane when cutting, which is convenient to fit the rootstock and more conducive to growth.

Third, rootstock selection

In addition to choosing this rootstock, you can also use bitter orange, orange and other fruit trees for grafting. Saw the rhizome into a horizontal plane, and then cut a gap between the bark and xylem with a knife.

4. Grafting.

Insert the section of the bud near the xylem of the rhizome. After the two are attached, tie them tightly with a film to prevent the buds from loosening and falling off. Wrap the top of the rootstock to prevent dehydration and drying, which will lead to grafting failure.

Extended data:

Maintenance methods of orange saplings:

1. Substrate selection: The requirement of soil selection is slightly acidic sandy loam with good drainage, and humus soil, sandy soil and cake fertilizer should be mixed when potted.

2, lighting management: it likes sunny light, so give it good enough light. Oranges like cool climate in summer, and should be placed in the shade when the light intensity is high.

3. Temperature management: Oranges like a warm and refreshing growing environment. When the temperature is low in autumn, they should be moved indoors in time, and the room temperature should be kept at 6 ~ 12 degrees Celsius in winter.

4. Nutrient management: from germination to flowering, use decomposed thin sauce residue water once a week. Applying more phosphate fertilizer after summer is beneficial to plant germination and fruiting.
