Rooting agent use knowledge

The rooting agent is an auxin compound belonging to the plant growth regulator accelerator. In the vegetable production application, there are a plurality of indole acetic acid, indolebutyric acid, naphthalene acetic acid, royal root, br rooting agent, sodium nitrophenolate and the like. Ingredients, the role of which is to maintain the apical dominance of plants in plants, induce the transport of assimilation products to products (fruits), and promote plant rooting.
The common rooting agent product rooting agent is used as a substance to regulate the growth and development of plants. The main components are naphthaleneacetic acid, gibberellic acid, indole acetic acid and the like. The rooting agents marketed are available in water and powder. Planting trees to root the rooting agent can accelerate the production of new roots and promote crop growth.
At present, the rooting agents on the market can be mainly divided into the following three categories: common rooting and seedlings (single-type compounds such as acetic acid and naphthaleneacetic acid or a mixture of the above-mentioned compounds according to scientific ratio), biological bacteria and Rooting agent compounding rooting agent (ABT biological rooting powder), nutrient elements and growth promoters compounding rooting agents (such as root dense, Fang Rungen, etc.).
Precautions for the use of rooting agent <br> First, pay attention to the concentration of the drug and the application site. Second, it must be combined with the cultivation measures. 3. Master the application period. 4. Apply the fertilizer in the colonization hole. The vegetable farmers are commonly called "the nest."
Preparation and use of common rooting agents <br> First, rice vinegar water solvent: choose high quality rice vinegar, and cold water in a ratio of 1:100 into rice vinegar aqueous solution, suitable for soaking seeds such as grapes, cuttings, will be inserted After immersing in the lower solution for 8 to 12 hours, the cuttings are taken out, which can significantly increase the survival rate and make the cutting seedling grow faster and stronger.
Second, the vitamin B12 solvent: take the medical vitamin B12 injection plus cold boiling water 1 times dilution, the lower part of the cutting strip in the dilution solution soaked for 5 minutes and then cutting. It can promote root growth and promote tissue healing.
3. Aspirin solvent: The germination rate can be obviously improved by soaking the cuttings with 0.01% aspirin solution. Soaking the transplanted seedlings with 0.05% aspirin solution can shorten the slow seedling period, prevent the seedlings from drying out and improve the survival rate.
Fourth, honey water solvent: flower asexual reproduction, usually use growth hormone to promote cutting rooting. If there is no auxin, the cuttings can be rubbed in the honey and then cut, which can increase the survival rate and promote rooting.
5. Potassium Permanganate Solvent: The base of the cuttings is immersed in a 0.1%-0.5% potassium permanganate solution for 10 to 12 hours, and immediately removed after removal.
Sixth, hormone solvent: Some cuttings are easy to flow glue, should be put into the water immediately after mining, and then treated with hormones. Commonly used hormones are cocaine acetic acid, rooting agents, and the like. The longitudinal impact of the base of the insert before processing is better. Hard branches generally use 5 ~ 10ppm dilution solution, the base of the cuttings is immersed for 12 to 24 hours; the shoots are generally 10 ~ 25ppm solution, dip 12 ~ 24 hours.
7. Willow leaching agent: The willow branches of the green leaf will be cut into 4 to 8 cm short branches, and 1 kg of willow branches will be soaked in 1.5 to 2 kg of water for about 10 days, which is the willow branches. Rooting fluid. When using, soak the flower cuttings for 5 to 6 hours, then cut them. After this treatment, the cutting seedlings can be rooted in 7 to 10 days, with high survival rate and robust growth.
8. Sucrose solvent: Take sucrose and boil it into 5%~10% sucrose solution. After natural cooling, the base of flowering cuttings such as rose, fig, alfalfa and poinsettia, which are more prone to rooting, are immersed in sugar liquid for 4-6 hours. The concentration of the sugar solution with slower rooting needs to be doubled (the higher the concentration of the sugar solution, the shorter the soaking time).
Method of using rooting agent <br> I. Soaking method: The concentration of the drug is low, the soaking time is long, and the dipping is generally 2-24 hours, and it is stored in a place with high shade and high air humidity.
Second, the dipping method: the drug concentration is high, the processing time is short, generally 5-15s can remove the cuttings, the relative soaking method is safe and convenient to use, and is currently widely used.
Third, the powder method: the rooting material and talc powder or clay or activated carbon powder are evenly mixed, formulated into a powder, using the cuttings after the powder is inserted, this method is relatively troublesome to operate, generally not used.
