Many, many garden enthusiasts, like their own cutting osmanthus ah, rose ah what. The following is to share the preparation and use of several rooting agents, we can try to improve the survival rate.

1, rice vinegar water solvent: choose higher quality rice vinegar, and cool water according to the ratio of 1:100 into rice vinegar solution, suitable for soaking such as grapes and other fruit wood cuttings, when used, the lower part of the cut in the solution soaked 8 to 12 hours after taking out cuttings, can significantly improve the survival rate, so that the cuttings grow faster and stronger.

2, aspirin solvent: with 0.01% aspirin solution soaked cuttings, germination rate can be significantly improved, with 0.05% aspirin solution soaked transplanted seedlings, can shorten the slow seedling period, prevent seedlings dry, improve the survival rate.

3. Vitamin B12 solvent: Take medical vitamin B12 injection and dilute it by 1 times with cold boiling water, and soak the lower part of the cut in diluent for 5 minutes before cutting. It can promote root growth and tissue healing.

4, willow branch leaching agent: the green branch of the willow branch, cut the leaves into 4 ~ 8 cm short branches, 1 kg of willow branches with 1.5 ~ 2 kg of water soaked for 10 days or so, that is, willow branch rooting solution. When used, the flower cuttings are soaked for 5 to 6 hours, and then cut. After this treatment, the cuttings can generally take root in 7-10 days, and the survival rate is high and the growth is robust.

5, sucrose solvent: Take sucrose with boiling water into 5% ~ 10% sucrose solution, after natural cooling, the more easily rooted rose, FIG, wolfberry, poinsettia and other flower cuttings base immersed in sugar liquid 4-6 hours after cutting. The concentration of sugar solution should also be doubled for the cuttings with slower roots (the higher the concentration of sugar solution, the shorter the soaking time).

6. Honey water solvent: When flowers reproduce asexually, growth hormone is usually used to promote rooting of cuttings. If there is no growth hormone, the cuttings can be dipped in honey and then cut, which can improve the survival rate and promote rooting.

7. Potassium permanganate solvent: The cuttings base is soaked in 0.1% ~ 0.5% potassium permanganate solution for 10 ~ 12 hours, and immediately after taking out the cuttings.

8, hormone solvent: some cuttings are easy to flow glue, should be put into water immediately after harvest, and then treated with hormones. Commonly used hormones are CAI acetic acid, rooting agents and so on. It is better to treat the longitudinal cut on the base of the front cut. Hard branches generally use 5 ~ 10ppm diluent, the base of the cuttings impregnated for 12 ~ 24 hours; The shoots are generally soaked in 10-25ppm solution for 12-24 hours.

In addition, the auxin was prepared into 2000-4000ppm high concentration solution for 5 seconds of rapid dipping, rooting effect is also very good.
