[Edit this paragraph] Breeding
The propagation of Daphne odora in Phnom Penh is mainly through cutting, layering, grafting or sowing. Cutting is mostly carried out before Qingming and long summer, and also in autumn. Cut off the top 8- 10 cm thick branches and leave 2-3 leaves. After soaking in rooting agent, insert them into the sand bed to the depth of 1/2 to 1/3, and then shade them. It takes about 40 days to take root. When people cut Daphne odora in Phnom Penh, they often split the lower end of the cuttings and put stones the size of rice grains to increase the contact area between the cuttings and the substrate and promote rooting. When cutting in early autumn, the temperature can be increased by covering the film on the string bed. For Daphne odora planted in the ground, soil balls should be brought when transplanting, which should be carried out in spring or autumn. Apply base fertilizer before frost sowing, then topdressing 1-2 times fertilizer, and then apply flower-promoting fertilizer before winter. However, potted Daphne odora in Phnom Penh should first choose a water-retaining and permeable medium, and at present, pond mud is mostly used. Because Daphne likes to be fat, topdressing should be done at any time, but not with human feces. In summer, flowerpots should be protected from direct sunlight and shaded.
[Edit this paragraph] Reproductive management
Propagation can be carried out in spring, summer and autumn, and cutting can be carried out from late February to late March in spring. The annual thick branches are about 10 cm, and the lower leaves are cut off, leaving 2-3 leaves, and then inserted into the seedbed. Summer is from mid-June to mid-July; Autumn planting is from late August to late September, and branches of the current year are selected. Cutting in summer and autumn, cutting off the strong branches of that year, and it is better to have internodes at the base of cutting, which is more conducive to rooting. Insert it in a river sand basin, about 2/3 deep, shade it after insertion, keep it moist, but not too wet, and take root in 45 ~ 60 days. If the base of cuttings is dipped in wood rooting powder, it is more beneficial for cuttings to take root.
High pressure propagation should be carried out in March-April when plants germinate new buds. First, select 1-2-year-old robust branches, peel them into a ring with a width of 1-2 cm, then wrap the incision with plastic sheets, fill it with soil, tie the lower end tightly, and tie the upper end of the plastic sheets tightly, but leave a small hole for ventilation and irrigation, and keep the soil moist in the bag, which can generally take root after more than two months. After autumn, cut off the mother pot or plant it alone.
Sex likes to warm the environment and is afraid of the hot sun and the cold. Avoid shade, rain and strong wind in summer; In winter, keep it indoors in sunny and sheltered places, and keep the room temperature above 8℃. Keep the leaves clean, and the soil in the basin should not be too dry or too wet; Don't catch cold, and don't let there be oil smoke and oil smoke indoors. I prefer loose, fertile and well-drained acid soil (pH 6-6.5) to alkaline soil. I can use mountain mud or pastoral soil mixed with 40% peat soil, humus soil, pine needle soil and appropriate amount of coal cake ash, rice husk ash and urban garbage as culture soil. When planting, you should choose a place that is semi-cloudy and semi-sunny, with deep topsoil and wet land. In winter, in order to avoid direct sunlight and get sunshine, deciduous trees and shrubs are often planted together. It can be transplanted in spring and autumn, but it is suitable to transplant in spring flowering period or plum rain period. Adult trees are not tolerant to transplantation, so when transplanting, we must take as much soil as possible and cut them down again.
Post-planting management, extensive cultivation in the open field, watering only when the weather is too dry; Before overwintering, apply some decomposed fertilizers around the plants. Potted Daphne odora in Phnom Penh should be kept semi-dry and semi-wet, and fertilizer should be applied once in spring and autumn. In spring, in the germination stage, 30% decomposed bean cake and chicken manure are mixed with liquid fertilizer; Autumn is in late September, and the fertilizer concentration should be light. Fertilization time should be chosen before 10 am in sunny days. Spray water on the leaves after 5 pm on the day of fertilization. Water can't be fresh tap water. It's better to dry it in the sun or store it indoors for one day. The water temperature can't be lower than the indoor temperature. Don't sprinkle fertilizer solution on the leaves. If spilled on leaves, rinse it with watering can water immediately. Fertilizers are mainly nitrogen fertilizer and potassium fertilizer, that is, cake fertilizer and fishy fertilizer are often mixed. But it must be a fully fermented fertilizer solution with a small amount of black alum water. The fertilizer of Daphne odora in Phnom Penh should not be strong, but weak. Note that the pot soil is too wet, and the temperature is too high or too low, which is not suitable for fertilization. Beginning in early summer, potted Daphne odora should be placed in the shade or shed to avoid strong light. The flowerpot should be placed directly on the ground to avoid the smell of flowers attracting ants and earthworms. Daphne odora in Phnom Penh is resistant to pruning. Generally, dense shoots can be pruned before germination, leaving a certain gap to facilitate ventilation and light transmission. Daphne odora in Phnom Penh should be pruned after flowering, and the flowering branches should be shortened, and the branches that affect the beauty of the tree, such as long branches, overlapping branches, over-dense branches and cross branches, should be cut off to maintain the beautiful shape. Daphne odora in Phnom Penh should turn over the pots and change the soil every two to three years, usually after the flowers wither or in autumn. Remove 2/3 of the old soil when turning the pot, and trim some redundant fibrous roots appropriately, which can be combined with turning the pot and lifting the roots appropriately.
Daphne odora in Phnom Penh can leave the house before the end of March in Tomb-Sweeping Day, but it is necessary to prevent strong winds and heavy rains, so as not to hurt the new buds of Daphne odora in Phnom Penh. Gradually shorten the lighting time at the end of April. From mid-June to mid-September, you can avoid light all day. Because Daphne odora in Phnom Penh basically stops growing in summer and enters a semi-dormant state. During this period, rain prevention and fertilization are prohibited. It is also necessary to create a cool and ventilated environment and reduce the amount of watering. Xia Hou can see some sunshine in the morning from the end of September to the beginning of 10, preferably for 2 to 3 hours. Later, the lighting time can be extended slowly, and it can be illuminated all day after 10. According to the different climatic conditions in different places, Daphne odora in Phnom Penh will enter the room in June 5438+ 10 or early June 165438+ 10, and put it in a position with long illumination time behind the room. In mid-June, dilute fertilizer solution was applied once in 5438+065438+ 10, and once in early and late February in 5438+June. Because the buds of Daphne odora in Phnom Penh grow slowly, the fertilizer should not be applied too frequently, too much and too thick, but it should be fertilized.
There are few pests and diseases of Daphne odora in Phnom Penh, and it is easy to cause root rot if the pot soil is too wet or the organic fertilizer is not decomposed. Spray 12% green milk copper emulsifiable concentrate 600 times, 50% carbendazim 800 times or 70% thiophanate-methyl 1000 every 15 days. The root of Daphne odora in Phnom Penh is sweet and vulnerable to ants and earthworms, so attention should be paid to prevention and control.
[Edit this paragraph] Maintenance management
Location: Daphne bonsai should be placed in a warm, humid, semi-cloudy and semi-sunny place. Avoid sun exposure in summer and put it under the south-facing window with light and air circulation in winter.
Watering: Daphne odora in Phnom Penh is not resistant to moisture, and the soil in the basin should be dry at ordinary times, so no water can accumulate. When the weather is hot in summer, water should be watered twice in the morning and evening, and the watering should be reduced correspondingly in spring and autumn, but in autumn of pregnancy, attention should be paid to the fact that the soil in the basin should not be too dry. When the weather is sunny and dry, you can often spray foliar water to make the branches and leaves moist, which is conducive to growth. In rainy season, you can move the basin under the eaves and windows to shelter from the rain.
Fertilization: Sufficient base fertilizer should be applied in winter. Apply 2 ~ 3 times of decomposed cake fat water in spring, and the fat water should not be thick. Stop smearing in summer to avoid burning the roots. After autumn, apply less fertilizer until the buds bloom. Fertilizer water with nitrogen and potassium as the main fertilizer is applied in spring, and phosphorus is the main fertilizer after autumn. After bud formation, 0. 1 ~ 0.2% potassium dihydrogen phosphate can be sprayed on the leaves for root fertilization, but fertilizer water should be sprayed on the back of the leaves to improve fertilizer efficiency and promote flowers to flourish. Daphne avoids using human manure fertilizer.
Pruning: Daphne odora is mostly pruned after flowering. Generally, the flowering branches can be shortened to promote more branches and increase the number of flowers in the next year. Cut off long branches, cross branches and overlapping branches, cut off branches that affect the appearance in time, and maintain a certain tree shape.
Pot turning: Do it every 2 ~ 3 years, preferably after flowering in spring and autumn. Bring more old-fashioned soil when turning over the basin, and don't move the roots too much. You can cut off some long fibrous roots appropriately. Foot fat must be put on the pelvic floor.
[Edit this paragraph] Winter maintenance
Daphne odora in Phnom Penh should be placed in a sunny place to receive light during the day and moved to a place not lower than 5℃ at night. In addition, it is also necessary to avoid the pot soil being too wet, avoid applying thick fertilizer and raw fertilizer, and avoid being wet.
Usually pay attention to the leaves of Daphne odora in Phnom Penh. If the leaves are straight and upward, it means that the fertilizer and water are normal; If the leaves droop, it means that the fertilizer is too thick, too raw, too diligent, or too much water, so it is necessary to find out the reasons and take corresponding measures. Too much watering is easy to correct. If the fertilizer is not used properly, it can be watered continuously to let the fertilizer run out of the pot, and then put it in a ventilated place to dry the pot soil quickly. If the root is rotten, you need to turn over the pot, cut off the rotten root, wash it with disinfectant, and then plant it in the sand to make it grow new roots. The upper branches and leaves should be cut off accordingly.
The basin soil is mainly neutral and slightly acidic sandy soil, in addition, 40% humus soil, pine needle soil, peat soil or rice husk ash should be mixed. Do not apply base fertilizer to basin soil, but apply liquid fertilizer in time. The liquid fertilizer is soybean water (grinding or boiling soybeans at least 1 year. Soybeans are best mixed with potassium dihydrogen phosphate solution (high-efficiency and quick-acting phosphorus and potassium fertilizer, diluted with 1000 times of water).
[Edit this paragraph] Pest control
Daphne odora has strong disease resistance, and occasionally aphids and red spiders do harm to it. Spraying 80% dichlorvos 1200 times solution or using Pomei 0.5 degree stone sulfur mixture can prevent and control it. Daphne odora in Phnom Penh has a sweet root system and is easy to attract earthworms. Therefore, the earthworms in the pot soil can be picked up when the pot is turned over, and the flowerpot should not be placed on the ground at ordinary times to prevent the earthworms from drilling out from the bottom of the pot.
The leaves of infected plants appear mottled and deformed, and at the same time, they bloom badly and rot their hearts. Prevention and control measures: before the arrival of high temperature and high humidity season, spray Bordeaux solution for 2-3 times and place it in a cool place. If you find rotten hearts, 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.
[Edit this paragraph] defoliation control
There are three main reasons why Daphne odora leaves in Phnom Penh.
1. The weather in midsummer is not only hot, but also heavy rain, heavy rain and thunderstorms, especially thunderstorms, come suddenly and with great intensity, resulting in a sudden drop in temperature and easy damage to the capillary roots of Daphne odora in Phnom Penh.
Second, after the rain clears, there is water in the basin, and the plants are in the sun and steaming environment, which hinders the respiration of the roots and easily causes root rot.
Third, excessive fertilization has exceeded the actual needs of plants, causing poisoning and inhibiting plant growth. Or apply heavy fertilizer that has not been fermented and decomposed, and the root system is damaged by fertilizer.
There is something wrong with Daphne odora in Phnom Penh, which is difficult to find at the moment. When its leathery leaves are still bright green, all the leaves will fall off. For plants that have fallen leaves, take them out of the flowerpot in time, rinse them with clear water, cut off all the broken and rotten roots, and then plant them in the flowerpot with river sand and place them in a well-ventilated and cool place. Always spray plants and flowerpots with a fine-eye watering can or sprayer to keep the surrounding environment moist. After more than a month, small leaves will grow on the branches. At this time, plants can be moved to scattered light, and plants will carry out weak photosynthesis, producing a variety of organic substances for their own metabolism and promoting the normal growth of plants. When the diseased plants grow new roots, replant them in loose and well-drained soil with PH value of 5.5-6.5.
[Edit this paragraph] Enjoy the flowers
Daphne odora in Phnom Penh has a graceful figure, a round crown, thick leaves, swaying branches and fragrant flowers, which means auspiciousness. It's better to watch it in early spring and February.

(b) Materials and cultivation measures
Artificial propagation: Daphne odora var. marginata is propagated by cutting and layering, or by cutting, dividing and sowing with water. 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. If the foreskin is circumcised at the branch point, the incision should be cut flat in time, and 2 ~ 4 leaves should be left at 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 to prevent sun and rain (bamboo pieces can arch a 50 ~ 60 cm high scaffolding and cover it with plastic film). 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 can usually be used for layering propagation. The time of high branch pressure should be in May-June. First, select the appropriate branches to determine the high-pressure parts, cut one or two circles horizontally or peel off the compressed parts by scribing method, and the incision reaches the xylem. Then, wrap the cut part with a plastic bag or a semi-bamboo tube, tie the lower end tightly, apply growth hormone to the wound, fill in the prepared culture soil, and wrap 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. The propagation of Daphne odora in Phnom Penh by water insertion method is simple and feasible, and the survival rate is high.

[Edit this paragraph] Frequently Asked Questions
Rotten heart and root phenomenon
The phenomenon of rotten heart and roots in Daphne odora cultivation in Phnom Penh is mainly caused by improper management. Daphne odora in Phnom Penh adapts to warm climate, but it is not resistant to strong light and prefers semi-shade. Its roots are fleshy, dry and wet resistant, and mosaic is prone to occur in high temperature and high humidity seasons. Infected plants have spots and deformities on their leaves, and at the same time, they have poor flowering and rotten hearts. Prevention and control measures: spray bordeaux mixture 2 before the arrival of high temperature and high humidity season? 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 sun and rain in summer. If suddenly attacked by wind and rain, it will wither and die immediately. If this happens, you need to move 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 into a new pot, cover them with plastic film and put them in the shade. After two weeks, if the leaves stand upright, they will be saved.
