Fast Rooting Methods for Seedling Cutting
Core content of this article: knowledge about flower propagation, ten fast rooting methods for seedling cutting, next[] the editor will introduce.
One, Spraying Rooting Agent on the Mother Tree
Apply rooting agent evenly to the mother tree two to three days before cutting the scions, which is absorbed by the buds and tender bark and then transmitted within the tree, can significantly reduce the growth-inhibiting substance tannin in the branches, enhance the germination ability, and promote faster rooting after cutting.
Two, Choosing the Best Time for Branch Collection
It is best to collect branches in the morning. In the morning, the branches of flowering plants have sufficient water content, heal quickly after cutting, and are easy to root, with a high survival rate.
Three, Cutting Flower Post Branches for Propagation
Flower post branches have the highest nutrient content and are relatively thick and full, making them easy to survive after cutting and quick to develop roots and leaves.
Four, Cutting Strong Stems with Heel
Cut the branches two to three centimeters below the junction of new and old branches to get heel-cut scions. They have more nutrients, dense tissue, easy to root, and have a high survival rate after cutting, with strong seedling growth. Suitable for propagation of osmanthus, camellia, fig, etc.
Five, Peeling and Notching Treatment Before Planting Scions
Circumferential stripping: Twenty days before cutting the scions, strip the base of the branches to be used as scions, 5 to 7 millimeters wide, which is beneficial for the scions to develop adventitious roots. Longitudinal notching: One month before cutting the branches of difficult-to-root flowering plants, notch the branches of the mother tree to maximize the accumulation of nutrients in the branches instead of flowing back to the mother tree, creating material conditions for rooting.
Six, Soaking Scions in Water Before Planting
For trees like persimmon and walnut that contain rooting inhibitory substances, soak them in water and change the water several times to leach out the tannin for easier rooting.
Seven, Pressuring Branches into the Soil Before Planting
For long and soft branches of flowering shrubs, use the method of pressing branches into the soil one to two months before planting to promote rooting. Apply rooting agent to the branches and then press them into the soil. After about 20 days, a large number of secondary roots will emerge. Try to retain the leaves on the branches, and if combined with notching, the root-promoting effect will be more significant.
Eight, Drug or Hormone Treatment
Soak the base of the scions in a 0.1% to 0.5% potassium permanganate solution for 10 hours, then plant immediately after removing, which can promote rooting in flowering plants. Soaking the base of the scions in a 5% to 10% sugar solution for 24 hours, then rinsing and planting can also promote rooting. Soaking the base of the scions in a vitamin B12 solution for 5 minutes, then slightly drying before planting has a good root-promoting effect. Common hormones include naphthylacetic acid, indole butyric acid, ABT rooting powder, etc. Notching the base of the scions before treatment can enhance the effect.
Nine, Adjusting the Temperature and Humidity of the Planting Bed
In winter and early spring, rooting of flowering plants is often difficult due to low soil temperature. It is possible to artificially raise the temperature at the lower end of the scions where rooting occurs, while spraying water and ventilating to lower the temperature of the upper buds, promoting rooting.
Ten, Facilities or Artificial Heating
Methods such as laying ground film, using electric heat beds, or applying manure fermentation to generate heat can be used to raise the temperature and accelerate the germination and rooting of flowering plants.
