Steps of grafting black pine
1, select the rootstock.
It's best to choose one cultivated for more than one year here. Black pine with strong trees and developed roots is used as rhizome.
2, processing rootstocks
First of all, the sand in the part to be grafted is washed clean to facilitate grafting. Then use a sharp knife to cut diagonally in one breath (the knife should be deeply embedded). Be careful here, don't cut the black pine too hard.
3. Treatment of scions
Subtract some pine leaves from the scion (too many pine leaves will lead to grafting failure), use a sharp knife at the micro end to fit the incision of the rootstock at the base of the scion, and pay attention to the smoothness of the incision.
4. Transplantation method
Insert the scion into the incision of the rootstock, align with the cambium, and apply some healing agent on the surface of the incision to increase the survival rate.
Step 5 bandage
First, wrap the interface with wrapping paper for grafting, remember to wrap it tightly without water leakage, otherwise it is not conducive to survival. Then put it in a plastic bag and seal it tightly to avoid leakage.
Step 6 observe unpacking
According to the growth of the scion bud head, slightly open the plastic bag until the bud is completely budded and the needles are dark green, which is basically successful grafting. At this time, the plastic bag can be removed.
7. Management after grafting
After the grafting is completed, you can pour some water and apply some fertilizer, but be careful not to wet the grafted parts. According to the growth of black pine, the wrapping paper can be removed and the dead parts can be cut off.
The secret of keeping black pine well
1, topdressing first and then cutting buds.
In this bud reduction period, pine trees should be fertilized more. For some weak pine trees, bud cutting will affect the subsequent germination. Therefore, fertilizer should be added properly before bud cutting.
2, irrigation misunderstanding
Don't confuse black pine with five-needle pine. When the black pine soil is too dry, water it more. As long as it is properly cultivated, black pine will not die because of excessive watering unless it is properly drained.
Step 3 Place the environment
Seedlings will not grow in dark and unventilated environment. Therefore, black pine should be planted in a ventilated and sunny environment.
Step 4: sunscreen
Miniature potted plants should be protected from the wind and frost, which is conducive to spring germination.
Bamboo is not relaxed at all, its roots are firmly embedded in the cracks in the rocks. After many trials and tribulations, it is still strong, and the wind is strong in the southeast and northwest-Zheng Banqiao. When encountering difficulties, we should all have the spirit of the pine tree in the poem.
