What is the grafting principle 1, grafting principle
The principle of grafting is to use the self-healing function of plants after injury to connect the growth tissues of the injured parts of two plants. The new branches and leaves of the grafted plant from the scion have the same shape as the scion and grow faster than the original plant.
Step 2 choose rootstock
Before grafting plants, plants with strong vitality, fast growth, cold resistance and drought resistance should be selected as rootstocks. Usually, the grafting survival rate of plants belonging to the same family is high, but the grafting of plants belonging to different families and genera is difficult to succeed and the later growth is weak.
3. Select cuttings
Before plant grafting, branches that are not damaged by plant diseases and insect pests should be selected as cuttings, and then two-thirds of the leaves on the cuttings should be cut off, leaving only 2-3 leaves at the top, and at the same time, the bottom of the branches should be obliquely cut to expose the white growth tissue of the plant, so as to better combine with the rootstock.
4. Preventive measures
Pay attention to prepare plastic rope, bracket and sunshade net in advance when grafting. Plastic rope and bracket need to be bound and fixed after grafting plants to avoid lodging. The sun-shading net is used to block the strong light of plant wounds and prevent the wounds from sunburn.
