Method, you can also use the method of inserting water, dividing plants and sowing. Cutting can be done all year round, but the best time is from early March to late June. In spring, annual stout branches should be selected, and the length is about 5 ~ 10 cm. You can cut a circle at the branch point of 0. 1 cm with a sharp knife one day before cutting to promote healing and rooting. At the branch point
Cut, cut the incision in time, and leave 2 ~ 4 leaves on the upper part of the incision; If it is not circumcised at the branch point, if there are several ramets, it can be cut separately. The insertion depth is about 1B3 or 1B2, which should not be too deep. Family cutting can use cutting pots, such as seedbeds for large-scale cutting, and the seedbeds should be loose, fertile and slightly acidic soil with good drainage. After insertion, a protective shed must be set up for sun protection and rain protection (bamboo pieces can be arched into a scaffold with a height of 50 ~ 60 cm and covered)
)。 When the temperature is too high, you must open the corner of the film shed for ventilation, and pay attention to controlling the humidity, which should not be too wet. Generally, it takes about 30 days to root in spring, and it can be transplanted into plants in about 2 months. For example, when cutting in summer and autumn, the cuttings should be semi-lignified new branches, thick branches, about 8 cm long, with heels on them. Keep the seedbed soil moist after transplanting, and pay attention to heat preservation when cooling down. Generally, it can also take about 40 days to take root, and then transplant and cultivate after the spring of the next year.
High-branch layering method can usually be used for reproduction. The time of high branch pressure should be in May-June. First, select the appropriate branch, determine the high-pressure part, and use
In this method, one or two circles or rings are cut transversely at the compressed part.
The incision reaches the xylem, and then the cut part is wrapped with a plastic bag or a half bamboo tube, the lower end is tied tightly, and the wound is coated.
Then fill in the prepared culture soil and tie the upper bag tightly. Keep the soil in the bag moist, and fix the high-pressure branches to avoid breaking. Generally, it takes about 40 to 50 days to take root, and it can be cut from the mother branch in about 2 months and put into a pot for cultivation.

Prevention and control measures: spray before the arrival of high temperature and high humidity season.
2? Three times, in the shade. If you find rotten hearts, you should cut off branches, leaves and flowers in time and burn them to prevent them from spreading. In particular, Daphne odora in Phnom Penh is delicate and difficult to raise, and it is afraid of humid and low-pressure climate. Therefore, Gao Shuang should be selected for planting and protection should be strengthened. During the growing period, be careful not to apply big fertilizer or water, and keep the soil in a semi-humid state. Avoid storms, rain and rain in summer.
If suddenly attacked by wind and rain, it will wither and die immediately. If this happens, it should be moved indoors in advance to avoid it; If it has been attacked by wind and rain, it is necessary to cut the length of 1- 1.5 cm from the cortex to xylem with a knife in time, so that the excess water and gas in the plant can be discharged for normal growth. If it is found that the leaves of plants are drooping, completely tarnished and slightly wrinkled, it means that the roots have rotted. If the roots develop first, they can be rescued: dig out the seedlings, wash the roots with clear water, cut off the rotten roots, then move them to a new pot and cover them.
