How to raise Phnom Penh Ruixiang in summer, how to raise Phnom Penh Ruixiang in winter / summer shade / winter temperature control

Summer and winter as the two most contrasting seasons of the year, many plants do not adapt to their growth, and Phnom Penh Daphne is no exception. About how to raise Ruixiang in Phnom Penh in summer? How to raise Ruixiang in Phnom Penh in winter? There are many things that need to be paid attention to. Let's take you to know it.

First, how to raise Ruixiang in Phnom Penh in summer

1. Water twice a day

Summer is the season with the highest temperature of the year, and the air is relatively dry. in this season, Phnom Penh incense will enter a semi-dormant state, at this time we need to keep the basin soil dry, but the humidity of the air should be maintained. we should spray water on its leaves every day to maintain the humidity of the air, and the frequency is usually twice a day.

two。 Light, kept in the semi-shade of the room

Although it needs a certain amount of light in the growth process of Phnom Penh, it is also a time to score. After entering the summer, we can let it receive sunshine for several hours in the morning, and when the sunshine is relatively strong at noon, we should move it to the indoor semi-shade in time, so as to prevent the plant from being burned and yellow and dry.

3. Pruning new twigs

Phnom Penh Daphne is a plant that is particularly resistant to pruning, and the top of the plant also has a strong advantage. after entering the summer, we need to prune the new branches in different periods of time, and the length of the pruning is generally 1/2 of the shoots. This can not only make the new buds on the side grow new branches, but also prolong the flowering period.

Second, how to raise Ruixiang in Phnom Penh in winter

1. Temperature, keep above 5 ℃

Winter is the coldest season of the year. In this season, we'd better keep Phnom Penh Daphne indoors and let it receive light for a few hours when the temperature rises at noon every day. When we keep it indoors, it is best to keep the indoor temperature above 5 ℃ to avoid frostbite caused by too low temperature.

two。 Water content, controlled watering

After entering the winter, the growth rate of Phnom Penh incense will become slow, so we should water it according to the situation. If its leaves are straight and straight up, which means that water and fertilizer is relatively normal, we can maintain the status quo. If the leaves are sagging, it means that there is too much watering or too much work, then we need to reduce the amount of water.

3. Antifreeze, add appropriate amount of antifreeze water

In winter, we usually keep Phnom Penh Daphne indoors, but even if we keep it indoors, we have to take antifreeze measures. We need to pour an appropriate amount of antifreeze water into the soil, which can improve the resistance of Phnom Penh Daphne to cold weather and make it through the winter smoothly.

How to raise Daphne odora in winter in Phnom Penh

Winter maintenance method of Daphne odora in Phnom Penh

Place a site

Since Frosts Descent, Phnom Penh Ruixiang should be moved to indoor maintenance. Put it in the south window to be exposed to the sun during the day, and move to a place with higher indoor temperature at night, not by the window, so as to avoid frostbite. Ensure that the indoor temperature is above 5 ℃ in winter and open windows for ventilation when the weather is clear.

Fertilization requirements

There can be no base fertilizer in the potted soil of Phnom Penh Ruixiang, and liquid fertilizer should be applied frequently. However, it should be noted that there should be no ants and earthworms in the potted soil. (although earthworms help to enhance the fertility of the soil, the presence of earthworms in family potted plants is still a bit disgusting. ), fertilization would rather be light than thick.

Liquid fertilizer mainly chooses soybean water or potassium dihydrogen phosphate solution. When fertilizing is too dense, it can be watered in time and poured several times in a row to let the fertilizer flow out from the bottom of the basin and reduce fertilizer damage, and then put the basin in a ventilated place to let the basin soil dry as soon as possible.

Watering method

The growth of Phnom Penh incense is relatively slow in winter, so watering should be based on the situation. If the leaves are straight and straight up, it means that the water and fertilizer is normal; if the leaves are drooping, it means that they are watered too much or too often. Find the cause and correct it in time.

If the rotten root is caused by too much watering, it should be dealt with in time, take off the plant in time, cut off the rotten root, wash it with fungicide, and then replant it. Of course, in order to make the plant recover as soon as possible, we can cut off part of the upper leaves to reduce nutrient consumption.

What about the winter buds of Ruixiang in Phnom Penh?

The florescence of Daphne odorifera in Phnom Penh is mainly in winter, but the winter environment is bad, and it is easy to drop buds if it is not properly maintained. We should make preparations in advance and pay attention to a few points:

Temperature control

Phnom Penh Ruixiang likes warmth and can't stand the bright light. Excessive sunlight and low temperature will cause buds to fall. In addition to controlling the temperature, it is also necessary to note that in a stuffy environment, Phnom Penh Daphne is easy to suffer from mosaic disease, which will cause a large number of buds falling, so it is necessary to spray Bordeaux solution in time to prevent and cure it.

Fertilizer application

After entering the autumn, we should pay attention to fertilization, apply thin fertilizer frequently, until the buds bloom. Before the formation of the bud, it is mainly phosphate fertilizer; after the bud formation, it can be replaced by potassium dihydrogen phosphate solution, foliar spraying, or root irrigation, fertilizer and water should be sprayed evenly to estimate the positive and negative sides of the leaf. So before winter comes, the buds have grown steadily on the branches, so there is no need to worry about falling buds!

Phnom Penh Ruixiang Daphne odora "Aureomarginata" Phnom Penh Daphne Picture: how to raise Phnom Penh Daphne / Phnom Penh Daphne how to breed Phnom Penh Daphne Business Card Phnom Penh Daphne Daphne odora "Aureomarginata" Phnom Penh Daphne introduction Phnom Penh Daphne is a traditional famous flower in China and also a famous flower in the world. In the history of modern horticulture, it is regarded as the three treasures of horticulture together with Changchun monk Gentleman and Japanese five-needle theory. Phnom Penh Ruixiang is famous for its "color, fragrance, appearance and rhyme", leaving behind the singing of "peony flowers are the best in Phnom Penh". The morphological characteristics of Phnom Penh Daphne odora is a variety of Daphne odora, which belongs to the evergreen shrub of Daphne odora. Fleshy roots. Leaves densely whorled oval, about 5--6cm long, wide 2--3cm, smooth and thick, leathery, both sides glabrous, dark green surface, light green back, golden margin, short petiole A terminal inflorescence, perianth tube-shaped, the upper four-lobed diameter is about 1.5cm, each flower is composed of dozens of florets, blooming from outside to inside, flowering for more than two months, during the Spring Festival, the flowers are purple and red in color and rich in fragrance. The ecological habits of Phnom Penh Ruixiang potted Phnom Penh Daphne, the pot soil should be fertile and loose, rich in humus and acidic rotten leaf soil, mixed with appropriate amount of river sand and mature cake fertilizer. Phnom Penh Ruixiang root is fleshy, usually maintenance and management should pay special attention to control watering, such as too much watering, basin soil is too wet for a long time, easy to cause rotten roots. After the rain, the stagnant water in the basin must be poured out in time. Although Phnom Penh Daphne likes semi-shade, it should be placed in a sunny environment in winter and spring. During the growth period, such as sufficient light and appropriate fertilizer effect, it can make Ye Dai, flowers and flowers strong. It should be placed in a well-ventilated shady place in summer, and water should be sprayed to cool down when it is hot. Phnom Penh Daphne prefers fertilizer and should be irrigated with thin liquid fertilizer every 10 days or so in the growing season. It is appropriate to apply sparse pancake fertilizer and water before and after flowering. After Frosts Descent moved into the sunny part of the room, the room temperature was kept at about 5 ℃, and the watering was controlled; the water content of the basin soil was controlled at about 45% before it could pass the winter safely. In addition, Phnom Penh Daphne has numerous branches, strong germination, resistance to pruning, and must be pruned after flowering. The distribution area of Phnom Penh Daphne is native to the Yangtze River Basin and grows in the shady and humid zone of low mountains and hills. According to the Records of the Qing Dynasty, an old monk in Lushan sat on a stone bench behind the temple. He heard the strange fragrance in his dream and rose happily, so he looked for it in the surrounding fragrant grass and got a thick leaf fragrant flower, which was transplanted into a pot in front of the Buddha and was called "Sleeping incense". Soon the Spring Festival was coming, and the fragrance of the flowers was not reduced, and there were many benefits for those who respected the Buddha. The salty word was given by the old Buddha, which was a sign of auspiciousness for a year, so it was renamed Ruixiang. Since then, the number of seed gatherers has increased day by day. After a long period of artificial cultivation and domestication, Phnom Penh incense with gilt edge was selected from the parent varieties of Daphne odorifera. "Phnom Penh Ruixiang" is produced in Dayu County, Ganzhou, Jiangxi Province. In March 1996, Dayu County was named as the only "hometown of Ruixiang in China" by the China Special products Economic Committee and other relevant departments. Cultivation techniques of Phnom Penh Daphne with its pure flowers and rich aroma, Phnom Penh Daphne is the first choice for potted flowers. The propagation method of Phnom Penh Daphne mainly adopts old wood and tender wood cutting. this method has the characteristics of high survival rate, easy to learn, labor-saving and labor-saving. 1. The old branch cuttings are collected before the spring plant sprout. generally from late March to early April, choose one-year sturdy branches with strong growth, good development, no diseases and insect pests and full buds. The strong branches of the same year were used in the softwood cuttings from June to July. 2. Cuttings cutting and treatment Phnom Penh Daphne is generally cut according to the upper, middle and lower parts of the seed strips, the middle and upper branches are the best, and the tips are the worst. Old wood cuttings require a roughness of more than 1 cm and a cutting length of 15 cm; tender wood cuttings generally have a cutting length of 10-12 cm, retaining only 2-3 leaves at the top of the branch, and all the rest are cut off. If the leaves left are too large, in order to reduce transpiration, the leaves left should be cut off. After cutting the cuttings, soak them in 0.5% Murray 5% sugar solution for 10-12 days, take them out and cut them. 3. The cutting technology chooses the cutting substrate with good permeability and pH value of about 5, and generally uses fine sand or vermiculite to retain water. Before cutting, cut the base of the cuttings from the middle with a sharp knife, with a length of 1.5-2 cm, and then clip a small pebble in the middle to prevent it from closing, increasing the contact area between the base of the cuttings and the substrate, which is conducive to the rooting of the cuttings. Insert 1 beat 3-1 stick 2 of the cuttings into the matrix to compact the matrix. 4. Manage after cuttage to keep the soil moist after cutting, supply the water needed for cuttings to take root in time, and keep the temperature at 20-25 ℃. At the beginning of the seedling stage, often irrigate with small water and clear water, in order to permeate the matrix, avoid turbid water and overflowing irrigation, so as to prevent the young leaves from getting muddy and burning. At the same time, pay attention to shade to avoid sun exposure. The root system of Phnom Penh Daphne has fragrance, so it is necessary to avoid the encroachment of ants and earthworms. one. The cuttings can take root in 30-35 days. Disease control of Phnom Penh Daphne Stem Rot Prevention and Control Phnom Penh Daphne is a precious flower and tree loved by the masses, but it is difficult to keep. The main reason is stem rot. Symptoms: the disease is not easy to be detected at the initial stage. The first manifestation of the disease is the rhizome. The phloem of the disease blackened and rotted, and gradually developed to the root. However, the xylem was normal, the leaves were green and did not fall until death, and no disease was found on the surface. 2. The characteristics of the disease: the onset period of the disease is from June to October, and the peak is from July to September. It is a period of high temperature and strong light. It was observed that the incidence rate was 37.5% when placed in sunny places throughout the day, while only 5% occurred when the sun was hidden from 9: 00:00 to 4: 00:00 p.m. The diseased plants are mainly 1-5-year-old plants with rapid growth in spring and numerous leaves, and have strong infectivity. In terms of cultivated soil, the incidence of easy drying of basin soil was significantly higher than that of good water retention. The incidence of decayed leaf soil with 80% and 20% river sand was significantly lower than that of rotten leaf soil with half and half river sand content. The incidence of fire dung soil with 100% soil is lower than that with high sand content. Prevention and control methods: according to the incidence characteristics of Phnom Penh Daphne and three years of practice, the prevention and control of stem rot can start from five aspects: 1. The selection of culture soil: choose the soil rich in humus with good drainage and water retention. This kind of soil can dig the surface rotten leaf soil directly from the mountain forest region and mix it with a small amount of river sand and rotten cake fertilizer, or choose vegetable garden soil to add part of the rotten leaf soil and a small amount of Phnom Penh Daphne and rotten cake fertilizer cultivated in the river sand shed. 2. The choice of environment for placing potted flowers: Phnom Penh Daphne is a kind of plant that likes cool and ventilated environment. From June to October, potted flowers should be placed in a cool place from 9 a.m. to 4 p.m. Or take the method of setting up a shed to solve the problem. 3. Pruning in time: the plants with exuberant growth and numerous branches and leaves in spring are treated with heart-picking and leaf-picking, and too many new sprouting branches are removed to control the evaporation of water too quickly. 4. Water management: the soil must be kept moist in summer and autumn, rather wet than dry, in order to ensure the water supply of the plant. 5. Treatment of diseased plants: once the disease occurs, the diseased plants should be disposed of immediately with pot soil, and flowerpots should be washed and disinfected. Other uninfected strains were washed and disinfected with 500-fold carbendazim to prevent the spread of the disease. In short, it is necessary to carry out comprehensive prevention and control of stem rot. On the basis of selecting the culture soil and doing a good job of shading in summer and autumn, 1-5-year-old plants can generally control the occurrence of stem rot. [5] symptoms of prevention and treatment of leaf spot: at the beginning of the disease, small chlorotic dots appeared on the leaf surface, but in the later stage, the disease spot was enlarged into a large near-round spot, the size of the spot was uncertain and there was black mildew. From April to September, the disease occurred first in the lower leaves of the plant, gradually to the middle and upper leaves, and gradually developed to the middle leaves. When the leaves were serious, the growth became weak until the whole plant died. Prevention and control methods: reasonable watering, waterlogging prevention, strengthening ventilation, more application of mature liquid fertilizer rich in phosphorus and potassium, timely cleaning of fallen leaves of diseased plants and concentrated burning, can also be prevented by spraying 1% Bordeaux solution in early spring. During the onset period, mancozeb, carbendazim and thiophanate methyl were sprayed on the leaves in turn every 7-10 days for 3-4 cycles. The prevention and treatment symptoms of Fusarium wilt: at the beginning of the disease, the old leaves turn yellow, turn brown and dry, and gradually expand to the upper old leaves. When the temperature rises in spring, the bacteria invade from the root wound, and the disease is particularly serious in the high-temperature and rainy season, generally from morbidity to death. The course of the disease is generally 15-45 days, which is extremely harmful. Control methods: reasonable cultivation, timely cleaning and destruction of diseased leaves and diseased branches, and disinfecting the soil with formalin or pentachloronitrobenzene before potting. In the early stage of the disease, the roots were irrigated with carbendazim or benzoate 800-fold solution once a week for 5-6 times, and the effect was obvious.
