Cuttings are the most commonly used methods for reproduction of flowers and trees. In order to increase the survival rate, some economically simple methods for promoting root growth are described below:
Take branches for early clippings to be good in the morning. In the morning, the flowers and trees have sufficient water content. After the cuttings, the wounds are easy to heal, they are easy to root, and the survival rate is high.
After flowering, the content of nutrients in the shoots was higher after flowering, and it was thick and plump, and the rooting was quick after the cuttings survived. It was easy to survive.
With cuttings from the new branch and the old branch at the junction of 2-3 cm under the cut, this type of branch is with cutting inserts. There are many nutrients between the litchi twigs, the organization is tight, the rooting is easy, the survival rate is high, and the seedlings grow stronger. Suitable for sweet-scented osmanthus, camellia, figs and so on.
Mechanical treatment: First, peeling: For the more difficult rooted varieties, first peel the cork layer before inserting, enhance the cutting ability of water absorption, and promote hair root; Second, vertical injury: 2-3 cm long with a knife From the wound to the phloem, an adventitious root can be formed in the longitudinal injury; the third is girdling: 15-20 days before cutting, the base of the shoot to be used for cutting is stripped and the cortex is 5-7 mm wide. The cuttings give rise to adventitious roots.
Increase the temperature at the bottom of the insertion bed. Early spring cutting often causes rooting difficulties due to insufficient soil temperature. Artificially increasing the temperature at the rooting position at the lower end of the cutting, and spraying water to reduce the ambient temperature at the upper end buds can promote rooting. The lower end of the seedbed can be increased in temperature by using a mulching membrane, an electric hotbed or a manure fermentation heat source.
Drug or Hormone Treatment (1) Immerse the base of the cuttings in a 0.1%-0.5% solution of potassium permanganate for 10-12 hours. Remove immediately after cutting. (2) Treat the cuttings with aqueous sugar solution at a concentration of 5%-10%. The base of the strips was immersed for 24 hours and then removed, rinsed with fresh water and cut. (3) Diluted with Vitamin B12 and diluted with water 1 times, remove the cuttings for 5 minutes, remove them slightly, and dry them; (4) Some cuttings are easy to flow and should be put into water immediately after harvest and then use hormones. deal with. The commonly used hormones include naphthalene acetic acid, indole butyric acid, and ABT rooting powder. Before the treatment, the base of the inserts will be cut vertically and the effect will be better. Hardwoods generally use 5-10ppm dilution; the base of the cuttings is impregnated for 12-24 hours; the tender shoots generally use l0-25ppm solution, immersed for 12-24 hours. In addition, auxin was formulated into a high-concentration solution of 2000-4000 ppm for 5 seconds and the rooting effect was also good.
Vitamin
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
