Cuttings of flowers and trees are a method of inheritance of fine varieties. Cuttings are also called asexual reproduction and are highly heritable. In order to increase the survival rate of cuttings and flowers, some methods to promote the rapid rooting of cuttings and flowers are introduced as follows:
It is better to take the branch in the morning for the morning. After the adjustment of the morning and evening flowers, the water content of the shoots was sufficient. After the cut branches were taken, the wounds were easily healed and rooted, and the survival rate was higher than that of branches taken at other times.
After the flowering branches and flowers, the flowering shoots had the highest nutrient content, and they were thicker and fuller. After the cuttings survived, the roots and leaves were faster.
With a cutting, the branch between the new branch and the old branch at the lower part of the node at 2 to 3 cm is cut, which is a cutting strip. The length of the cuttings is generally 10 to 12 cm. There are many nutrients between the new and old branches, the tissues are tight, the hair roots are easy, the survival rate is high, and the seedlings grow strong. This law applies to Camellia, Osmanthus, figs and so on.
Mechanical treatment First, peeling: For the more developed fruit tree branches, more difficult rooted varieties, peeling the cork layer before the first cut, strengthen the cutting ability of water absorption can promote rooting. The second is vertical injury: knife wounds 2 to 3 cm long to the phloem, in the longitudinal injury can form a neat row of adventitious roots. The third is ring peeling: in the mother plant is ready to use as a base of the cuttings to peel off a ring of cortex (usually 15 to 20 days before cutting), a width of 3 to 5 cm, is conducive to promote the early insertion of shoots adventitious roots.
Increase the temperature at the bottom of the inserting bed. Early spring cuttings cause rooting difficulties due to insufficient soil temperature. Therefore, artificially increase the temperature of the rooting position at the lower end of the cutting, and spray water to reduce the ambient temperature of the upper end buds. At the lower end, the temperature is increased by using a mulching membrane, an electric hotbed, or using straw and stalks to generate heat. Put a layer of sand or sawdust on the surface of the bed before inserting, and the thickness should be 3 to 5 cm. Insert the cuttings in bundles upright or in rows. The gaps are filled with wet sawdust and the top buds are exposed to more than 3 cm. The base temperature of the insert is maintained at 20°C to 28°C.
Pharmaceutical or hormone treatment The base of the cutting insert is immersed in a 0.1% to 0.5% solution of potassium permanganate for 2 to 12 minutes, soaked for 1 to 12 hours.
2. The cuttings were treated with aqueous sugar solutions. The concentration of white sugar water used in plants and flowers is 2% to 5%, and the concentration of sugar water used in woody flowers is 5% to 10%. The base of the cutting insert is immersed in the above solution for 24 hours and then taken out. After the insert is washed with clean water, the adhered sugar liquid is rinsed.
3. With medical vitamin B12 injection diluted with 1 times cold boiled water, the base of the cuttings was immersed for about 5 minutes and then taken out. Slightly dry for a while until the liquid was absorbed and then cut.
4. Some easy-to-flush cuttings should be placed in water immediately after harvest and treated with hormones. Commonly used hormones include naphthaleneacetic acid (NAA), indole butyric acid (IBA), and ABT rooting powder. Treating the base of the front insert with a vertical injury has a better effect. The methods are as follows: First, the powder powder method. The talcum powder is used as a diluting filler and can be used within 2 to 3 hours after mixing 500 to 2000 ppm of the mixture. The base of the cutting insert is first impregnated with fresh water, and then the powder is used for cutting. The second is impregnation. Hard branch generally use 5 ~ 10ppm dilution, cutting base immersed for 12 to 24 hours, in addition to auxin into a high concentration of 2000 ~ 4000ppm solution for 5 seconds seed speed. However, it is also useful for 500 to 1000 ppm, and for immersing for 1 to 2 hours, the rooting effect is also very good.
