Reproduction technology:
First, determine the cutting time cutting cutting time depends on the different cultivation period, generally until the mother planting colonies grow, cut off lateral branches or buds cuttings.
Second, set the cutting site in the shed temperature and humidity suitable, sunny conditions, can be inserted in the 畦 钵 钵 钵 畦 畦 钵 钵 钵 , , , , , , , , , , , , , 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。.
Third, the selection of cuttings cuttings in the strong growth potential, strong disease resistance of the cuttings selected lateral branches. Generally selected to grow robust, dark green leaves, short internodes, 15-20 cm long, with 4-5 sections, well-growth lateral branches or lateral branches as the cuttings.
Fourth, the early treatment of cuttings
1. Pruning. After the collateral is selected, it is gently cut from the base with a blade. The incision should be smooth and horseshoe-shaped to facilitate wound healing; the lateral branches can also be axillary from the base and the base of the collaterals can be slightly rounded and the lateral branches can be enlarged. The contact surface with the soil accelerates the rooting speed. Then, keep the top pair of leaves and remove the rest. After the cuttings are cut, put them in the room for 3-5 hours to reduce the wound flow and facilitate rooting.
2. Promote roots. In order to promote hair rooting, the 2-3 cm long part of the cut twig was immersed in naphthalene acetic acid with a concentration of 500 mg/kg, soaked for 5 seconds and immediately removed.
5. The cutting technique inserts the processed shoots into the substrate to a depth of about 5 cm, and the jacks are appropriately compacted after insertion. When the temperature is high, shade and moisturize properly.
Six, post-cutting management
1. Pre-management. In the early stage (wound healing period), the temperature is maintained at 20-28°C during the day, 13-16°C at night, and the ground temperature is maintained at 16-20°C. When the temperature exceeds 30°C, shading, ventilation, and cooling should be properly applied to prevent wilting of leaves. The relative humidity of air should be kept above 90%.
2. Mid-term management. After 5 days of cutting, the branches cut and healed, and the adventitious roots began to sprout. The branches had a certain amount of water absorption and fertilizer retention. At this time, the daytime air temperature is maintained at 25-28°C, nighttime is 15-17°C, and the ground temperature is maintained at 18-20°C. The time and intensity of illumination may be appropriately increased.
3. Late management. After 15 days of cutting, 5-7 new roots with a length of 5 cm or more and many short and sudden adventitious roots have germinated at the lower end of the shoot. At this time, the water absorption and fertilizer absorption ability of the root can basically meet the needs of the growth of the cuttings, and the cuttings become new plants, which can be managed according to the normal seedlings.
