Role and use of rooting agents
Today, Xiaobian will explain to you the role of rooting agents and relevant knowledge of its use. Please see the detailed introduction below. Role and use of rooting agents Rooting agents are one of plant growth regulators. Their role is to promote plant rooting and have a great role in cuttage propagation of plants. In addition, it can also promote transplanted trees to grow more new roots and improve the survival rate of transplanting. The main rooting agents are indole butyric acid, indole acetic acid, and naphthylacetic acid. Different plants have different sensitivity to rooting agents, so the mixed use of two or more rooting agents has a better effect.
Rooting agents can promote the roots of plants. The roots are like the mouth of the plant, absorbing (S-Y) components and water, maintaining plant growth, and bearing fruit. Only when the root system grows well can high yields be possible. Rooting agent ingredients
Rooting agents are auxin compounds belonging to the category of plant growth regulators and promoters. They include indole acetic acid, indole butyric acid, naphthylacetic acid, royal root sheng, br rooting agent, compound sodium nitrophenolate and other ingredients in vegetable production and application. Role of rooting agents
1. Promote plant rooting
Rooting agent is a type of plant growth regulator. Its role is to promote plant rooting and has a great role in cuttage propagation of plants. Different plants have different sensitivity to rooting agents, so the mixed use of two or more rooting agents has a better effect.
2. Promote the growth of new roots
In addition to promoting the rooting of cuttage branches, the roots are dipped or sprayed with an aqueous solution of the rooting agent during tree transplanting. This can encourage transplanted trees to grow more new roots and improve the survival rate of transplanting. How to use rooting agents
1. Soak the lower part of the cutting branches with low concentration rooting agent
It is to soak the lower part of cuttage branches, such as rose cuttage branches, with a low-concentration rooting agent aqueous solution. Soaking it in an aqueous solution of 50 mg/kg of indolebutyric acid and naphthylacetic acid for 1 hour can significantly promote the rooting of branches during the cuttage breeding process.
2. Treating cuttage branches with high-concentration rooting agent solution
Treat cuttage branches with a high-concentration rooting agent solution for a short period of time, such as using an alcohol solution of 1000 mg/kg of indole butyric acid or other rooting agent. Soak the lower part of the cuttage branches for 3-5 seconds, dry and then cut, which also promotes rooting.
3. Mill into powder and use
First dissolve the rooting agent in alcohol, then stir well with talcum powder, then dry in the shade, and grind into powder. When using, the branches are first wetted with water, then dipped in the powder before cuttage.
The great advantage of this treatment method is that it saves chemicals. After making into dry powder, the rooting agent will remain active for a long time. However, the aqueous solution rooting agent maintains its vitality for a short time and becomes ineffective after 3 days at room temperature. Method for making rooting agent
1. Rice vinegar water solvent
Select high-quality rice vinegar and mix it with cold boiled water in a ratio of 1:100 to make a rice vinegar aqueous solution, which is suitable for soaking fruit wood cuttings such as grapes. When in use, soak the lower part of the cuttings in solution for 8-12 hours and then take out the cuttings, which can significantly improve the survival rate and make the cuttings grow faster and stronger.
2. Aspirin solvent
Soaking cuttings with 0.01% aspirin solution can significantly improve the germination rate. Soaking transplanted seedlings with 0.05% aspirin solution can shorten the slow seedling stage, prevent seedlings from drying out, and improve the survival rate.
3. Vitamin B12 solvent
Take a medical vitamin B12 injection and add cold boiled water to dilute it one-fold. Place the lower part of the cutting edge in the diluent and soak it for 5 minutes before cuttage. It not only promotes root growth, but also promotes tissue healing.
4. Willow branch extractant
Remove the leaves and cut the tender willow branches into 4-8 cm short branches. Soak 1 kilogram of willow branches in 1.5-2 kilograms of water for about 10 days to obtain the willow branch rooting solution.
5. Sucrose solvent
Take sucrose and rinse it with boiling water into a 5%-10% sucrose solution. After naturally cooling, soak the base of flower cuttings such as rose, fig, wolfberry, and poinsettia that are easy to take root in the sugar solution for 4-6 hours before cuttage.
6. Honey water solvent
When flowers reproduce asexually, growth hormones are usually used to promote cuttage rooting. If there is no auxin, you can dip the cuttings in honey and then cut them, which can improve the survival rate and promote rooting.
7. Potassium permanganate solvent
Soak the base of the cuttings in 0.1%-0.5% potassium permanganate solution for 10-12 hours, and cut immediately after taking out.
8. Hormonal solvents
Some cuttings are prone to glue flow and should be put into water immediately after harvesting and treated with hormones. Commonly used hormones include acetic acid, rooting agent, etc. The effect is better if the base of the cuttings is cut vertically before treatment.
Hard branches are generally soaked with 5-10ppm diluent and the base of the cuttings is soaked for 12-24 hours; young branches are generally soaked with 10-25ppm solution and soaked for 12-24 hours.
