How to raise Ruixiang flowers, the breeding methods and precautions of Ruixiang / like fertilizer and avoid stagnant water

Daphne flower, also known as romantic tree, its tree shape is natural and unrestrained, the color is small and white, and the flower is full of fragrance, it is a kind of flower loved by flower friends. Life kind, after knowing the Ruixiang flower, many people want to raise it, then how to raise the Ruixiang flower? The following are the breeding methods and precautions of Ruixiang sorted out by the editor, which are very detailed. Friends who want to raise them must have a look at them.

First, how to grow fragrant flowers indoors and understand their habits

Daphne likes warm, moist semi-shady environment, it is not cold-resistant, avoid hot, but also afraid of direct light. When breeding indoors, the Daphne pot should be planted in a semi-shady place, properly watered to keep the pot soil moist, and warm measures should be taken in winter. As for the cultivated soil, it is best to choose the loose and fertile sandy loam with good drainage. So how to raise Daphne requires us to meet its growth habits.

2. Culture methods and matters needing attention of Daphne odora

1. Soil

Although Daphne has been cultivated and domesticated, it is still difficult to raise it well, so how to raise it, we should first re-choose potted soil and start with the most basic. Because the potted plants of flower friends are basically purchased online, but the soil is very cheap, normal maintenance can ensure plant growth, but if you want Ruixiang flowers to grow well, it is best to re-choose the soil.

Soil selection: according to the growth habits of Daphne odorifera, it likes loose, fertile, well-drained, slightly acidic sandy loam rich in humus. In this regard, the editor recommends that you use: 5 parts of garden soil (mountain soil) and 2 parts of rotten leaf soil (pine needle soil) mixed soil.

2. Lighting

The growth of Daphne odorifera is rare, but it is also afraid of strong light, so in the breeding methods and precautions of Ruixiang, we should pay attention to the light. In summer, plant the Daphne pot in a well-ventilated semi-shady place; in spring, autumn and winter, it should also be placed in a semi-shady place, and in the case of relatively low temperature, it can be placed on the balcony to receive sunlight.

3. Watering

Water is the source of life, so how to raise fragrant flowers? Watering is indispensable. However, Ruixiang flowers are fleshy roots, so they are more drought-resistant, so they should be watered less and not more. Otherwise, it is easy to cause the basin soil to be in a wet state for a long time, which can easily cause rotten roots, poor plant growth and even death.

4. Fertilization

After watering, let's talk about fertilization, which is also a very important part of the breeding method of Ruixiang. Ruixiang flower likes fertilizer, in its rapid growth period, we should give it liquid fertilizer every 10 days, pay attention to low fertilizer concentration.

Note: there are several points to pay attention to when fertilizing Daphne odorifera. First of all, human feces and urine can not be used as its fertilizer; second, the summer temperature is high, Daphne will enter a dormant state, at this time to stop fertilization, so as not to burn the roots.

5. Pruning

In the process of cultivating Daphne odorifera, for the healthy growth of the plant, but also for its beauty, we should prune it timely. First of all, before sprouting, cut off the denser branches to facilitate ventilation and light transmission; secondly, after the flowering period, cut the branches where the residual flowers are located, cutting off the overgrown branches, cross branches, overdense branches and overlapping branches, so that they can remain beautiful.

6. Change the basin

In the breeding method of Ruixiang, there is also a certain need for everyone's attention, that is to change the basin. You should change the potted soil for the fragrant flowers every 2-3 years, usually after the flowers fade, replace 2% of the old soil, or replace all the old soil with new soil.

Introduction to the culture methods and matters needing attention of Daphne odora in Phnom Penh

Even if Ruixiang is actually a traditional famous flower of our country, of course it is also a famous flower of the world. In the history of modern horticulture, it was praised as the three treasures of horticulture in the world together with Changchun monk Gentleman and Japanese five-needle pine, and Phnom Penh Ruixiang is famous for its color, fragrance, appearance and rhyme, leaving the peony national fragrance and the best chanting in Phnom Penh. So what do we need to pay attention to if we want to raise it? Let the editor explain it to you in detail today.

[growth habits] the general potted Phnom Penh Daphne, whose potted soil is most suitable for using fertile, loose, humus-rich and acidic saprophytic soil, can also be mixed with an appropriate amount of river sand and rotten cake fertilizer. And Phnom Penh Ruixiang root is fleshy, usually maintenance and management should pay special attention to control watering for it, such as too much watering, and the basin soil is too wet for a long time, it will easily 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, and if it has sufficient light and suitable fertilizer effect during its growth period, it can make Ye Dai 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. Because Phnom Penh Daphne prefers fertilizer, we can apply dilute liquid fertilizer every 10 days or so during its 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 survive the winter. In addition, Phnom Penh Daphne has numerous branches, strong germination, resistance to pruning, and must be pruned after flowering.

[culture method] potted plant management: Daphne is actually also called Penglai flower or Qianli incense. It also belongs to the evergreen shrub of Daphneaceae, and is famous for its fragrance. Its variety is Phnom Penh, and it is a good product of Daphne odorifera. And we need to know the propagation method of Phnom Penh Daphne, which is mainly carried out by cutting old and tender branches. This method has the characteristics of high survival rate, easy to learn and labor-saving. Potted Phnom Penh Daphne, pot soil is also the most suitable to use loose, humus-rich slightly acidic rotten leaves or mud (or frozen crisp pond soil), mixed with appropriate amount of river sand and rotten cake fertilizer. Although Phnom Penh Daphne belongs to the plant that likes semi-shade, it should be placed in a sunny environment in winter and spring, because during its growth period, such as sufficient light and suitable fertilizer effect, it can make Rou Ye Dai, it is appropriate to apply thin pancake fertilizer water or rotten chicken and duck manure before and after flowering. After Frosts Descent, move into the indoor sunny place, keep the room temperature at 5 degrees right, and control watering; the water content of basin soil should be controlled at about 45% before it can pass the winter safely. In addition, Phnom Penh Daphne has numerous branches, and it has strong germination and resistance to pruning, so we can generally prune it after flowering.

Watering: the leaves of Phnom Penh Daphne are leathery, glossy and contain a lot of wax, so the transpiration of the leaves is very small, so it is not resistant to moisture, we should see dry and wet in normal watering. At the beginning of spring, the buds were watered once when they were about to sprout, and then poured thoroughly after the basin soil was dry. In summer, in addition to keeping the basin soil dry and wet alternately, it is also necessary to spray water around it and leaves regularly to cool down. The basin soil is in a semi-dry state at the end of autumn, which slows down the growth potential and is beneficial to overwintering. When the growth stagnates in winter, the basin soil should be dry and watering should be less. Fertilization: although Phnom Penh Daphne does not like big fat, we still need to apply mature thin fertilizer solution to it once a month. Applying the thin fertilizer solution before and after its flowering can make the plant luxuriant and the flowers fragrant and colorful. Be careful not to splash the fertilizer on the leaves. Fertilization should also be carried out when the basin soil is dry, and it is taboo to apply human dung and chemical fertilizer to it.

6. Cultivation techniques

Planting method the propagation of Daphne odorifera is mainly by cutting, but also can be striped, grafted or sown. Cuttings are mostly carried out before the Qingming Festival and the Beginning of Summer, or in autumn. Cut the sturdy branches at the top of 8ml 10cm, leave 2Mel 3 leaves, soak them in the root promoter and cut them into the sand bed with a total length of 1pm 2 to 1max 3, then take shade and take root in about 40 days. Daphne cuttings are often cut at the lower end of the cuttings and sandwiched into pebbles the size of one meter to increase the interface between the scion and the substrate to facilitate rooting. The Beginning of Autumn can be covered with film on the cutting bed to increase temperature when cutting. For Daphne odora planted on the ground, it should be carried out with soil balls in spring or autumn, applying basal fertilizer before frost, applying fertilizer twice after frost, and applying flowering fertilizer again before the beginning of winter, while potted Daphne should first choose a cultivation medium that is both water-retaining and permeable, and use pond mud. Because Ruixiang likes fertilizer, it should be fertilized at any time, but it is not suitable to use human feces and urine. Flowerpots should be protected from direct sunlight and shaded in summer.

Cuttage propagation

Phnom Penh Ruixiang likes the sun but is afraid of the hot sun, so it is resistant to dry and avoid wet soak. it is appropriate to use exposed pond mud and humus as pot soil for planting, which can ensure flowering during the Spring Festival by controlling light, temperature and moisture.

Phnom Penh incense blossoms without seed, mainly propagates by cutting, which can be carried out in spring, summer and autumn, and the survival rate of summer cutting propagation is the highest. Cuttings select current-year semi-lignified branches, the cut should be smooth, the scissors or blades should be sterilized with alcohol lamp or lighter at high temperature, the branches should be cut into 8 cm long, and 4-6 leaves should be reserved. After partially soaking in the special rooting agent, the cuttings should be stained with carbendazim powder and inserted into the culture material with 3 bank 5 of the plant. When the culture material is carbonized but not ash, pour the flameout husk ash with cold water, scald with boiling water or remove alkali and sterilize with potassium permanganate solution. Film mulching for 15 days to moisturize, generally 30 days to root, 50 days to transplant on the pot. It is better to use isolated air fermentation to mature human feces and urine or cake fertilizer and water, do a small amount for many times, and apply phosphorus and potassium fertilizer appropriately. Combined with pruning shape to kill insects, make Phnom Penh Daphne tall and straight and elegant. The Spring Festival can produce bursts of fragrant and brightly colored flowers, and after the second year it can grow into a large and graceful bonsai.

Field management and propagation can be cut in spring, summer and autumn, and cut in late February to late March in spring. About 10 cm of sturdy annual branches are selected, the lower leaves are cut off, 2-3 leaves are retained, and then inserted into the seedbed; summer cutting is from mid-June to mid-July; autumn cutting is from late August to late September, and current year branches are selected. Cutting in summer and autumn, cut off the sturdy branches of that year, and the base of the cuttings had better have internodes, which is more conducive to rooting. Insert in the river sand basin, about 2 canopy 3 deep, insert shade, keep moist, but not too wet, 45-60 days, can take root. If dipped in woody rooting powder at the base of cuttings, it is more conducive to the rooting of cuttings.

The propagation under high pressure should be carried out when the new buds sprout from March to April. First of all, select 1-2-year-old sturdy branches, do 1-2 cm wide ring peeling treatment, and then cover the cut with plastic sheeting, fill it with soil, tie the lower end tightly, and tie the upper end of the plastic sheet tightly, but leave a little hole for air permeability and irrigation, keep the soil moist in the bag, and generally take root after more than 2 months. After autumn, cut off the mother and put it on the pot or plant it separately.

Sex likes the warm environment, fears the hot sun, likes the shade, fears the cold. It should be shaded, protected from rain and strong wind in summer, and kept indoors in sunny and sheltered places in winter to maintain a room temperature of more than 8 ℃. Keep the leaves clean, keep the basin soil dry or too wet; do not be frozen, do not let indoor soot and oil fume. Like loose, fertile, well-drained acid soil (pH value 6 to 6. 5), avoid alkaline soil, use mountain mud or pastoral soil mixed with 40% peat soil, rotten leaf soil, pine needle soil and appropriate amount of coal ball ash, rice husk ash, municipal garbage and so on as culture soil. When planting, we should choose half-yin and half-yang, deep topsoil and moist soil. In order to avoid direct sunlight, and can be exposed to sunlight in winter, the method of mixed planting with deciduous trees and shrubs is often used. Transplantation can be carried out in both spring and autumn, but it is suitable to be transplanted in spring flowering or Meiyu period. Adult trees are not resistant to transplant, so you must bring as much lodging soil as possible and re-cut it.

In the management after planting, open field cultivation is relatively extensive, watering only when the weather is too dry, and some rotten barnyard manure is applied around the plants before overwintering. Potted Daphne should keep the potted soil semi-dry and semi-wet and apply fertilizer once in spring and autumn. In spring, the mixed liquid fertilizer of 30% rotten bean cake and chicken manure is used in the sprouting stage, and the fertilizer concentration is light in late September in autumn. The time for fertilization should be on a sunny day, preferably before 10:00 in the morning. Spray water on the leaves after 5 p. M. on the day of fertilization. Water can not use newly released tap water, it is better to be exposed to the sun, or indoor water stored for a day, the water temperature can not be lower than the indoor temperature. Do not sprinkle the fat liquid on the leaf surface, if sprinkled on the leaf surface, rinse it off immediately with spray kettle water. Fertilizer is mainly nitrogen fertilizer and potash fertilizer, that is, it is often mixed with cake fertilizer and fish fertilizer. But must be fully fermented fat liquid, but also add a small amount of black alum water. The fertilizer of Ruixiang should not be thick, but should be thin. Be careful not to apply fertilizer when the basin soil is too wet and the temperature is too high or too low. From the beginning of summer, potted Daphne should be placed in the shade or shade to avoid strong light. Plant pot taboo directly on the ground, lest the aroma of flowers attract ants and earthworms. Daphne is more resistant to pruning, generally can prune the dense twigs before germination, leaving a certain gap to facilitate ventilation and light. Daphne should be pruned after flowering, cut short the flowering branches, and cut off the overgrown branches, overlapping branches, overdense branches, cross branches and other branches that affect the beauty of the tree, so as to maintain a beautiful shape. Daphne should turn the pot and change the soil every 2 to 3 years, usually after the flowers fade, or in autumn. When turning the basin, remove 2pm and 3 old soil, properly trim some excessively long fibrous roots, can be combined with turning the basin and lift the roots properly.

Ruixiang can go out of the room before Ching Ming Festival at the end of March, but it is necessary to prevent strong winds and torrential rain so that the new buds of Ruixiang will not be hurt. The lighting time was gradually shortened by the end of April. There will be no light all day from mid-June to mid-September. In summer, Daphne basically stopped growing and entered a semi-dormant state. During this period, rainstorm is prevented and fertilization is strictly prohibited. But also to create a cool and ventilated environment to reduce the amount of water. After the summer, Ruixiang can see some morning sunshine from the end of September to the beginning of October. It is better to have 2 to 3 hours. The sunshine time can be extended slowly later, and the whole day will be illuminated by the end of October. According to the climate of different places, Ruixiang will enter the room in October or early November, and the room will be placed in a place with long light. In the middle of November, early and late December, the thin fertilizer solution was applied once respectively, because the flower buds of Ruixiang grew slowly, and the fertilizer could not be applied too frequently, too much or too thick, but it also had to be fertilized.

Phnom Penh Daphne has poor ability of sexual reproduction and uses more vegetative organs to reproduce. Therefore, seedlings are in short supply and expensive. The vegetative propagation of Phnom Penh Daphne can be carried out all the year round, usually by cutting, grafting, high branch pressing and so on. The methods of water insertion and bud insertion are introduced below. Water insertion and bud insertion

Water plug. Water insertion is generally carried out in summer, when new branches tend to mature, which is a good season for water insertion. The water insertion method has the advantages of fast rooting and high survival rate (almost 100%), which can reduce the number of water spraying. The specific method is: take the branches of the same year, with a length of 8-12 cm. The day before cutting, it is best to cut a circle with a sharp knife at the branch point of 1-2 mm (scissors are not available), so as to speed up healing and rooting. After ring cutting at the branch point, smooth the wound, remove the lower half of the branch leaves, keep 3-4 leaves in the upper part, and cut off the rest. And then put it in a jar prepared in advance. Pour water into the bottle about 3pm 4 and drip 2-3 drops of vinegar. The cuttings are about 1 stroke 3 in water, straightened and fixed. The mouth of the bottle is covered with gauze and fastened. Insert it and put it on the indoor windowsill. When the amount of water decreases, add water to the original water level. After about 5 days, spray the foliar surface with water 1-2 times, change the water once a week, and take root within a month. Transplant it into the pot in time.

Sprouts. Before sprouting in spring, the cuttings are selected from the middle and upper part of the crown, which are full and strong, leaving an upper leaf, and there should be obvious bud points in the axil of the bud, and the cuttings of one leaf and one bud are better. When picking the ear, you should use a sharp knife from the upper part of the axillary bud, cut it obliquely and cut it into a horse ear shape. Be careful not to damage the axillary bud to facilitate rooting and sprouting. Pine leaf soil and 30% fine sand are used as cutting substrate to facilitate the insertion and fixation of short cuttings. It should be noted that pine soil and fine sand substrate before cutting should be exposed to the sun and sterilized. When cuttings are inserted into the soil, the cuttings are solid, sprinkled with water and kept moist, which can take root and survive in about 40 days. After the new branches are produced, they will be transplanted into the pot in the following spring.

Selection and cultivation measures of bonsai production

[artificial propagation]: Daphne incense multipurpose cutting, striping method, can also be used in water cutting, ramet, sowing method. Cutting can be carried out all the year round, but the best time for cutting is from early March to late June. Spring cuttings should select one-year-old stout branches as cuttings, which are about 5-10 cm in length. They can be cut around 0.1 cm at the branch point with a sharp knife the day before cutting to promote healing and rooting. If it is cut in a ring at the branch point, the cut should be cut and trimmed at the right time, and 2 or 4 leaves should be retained in the upper part of the cuttage; if it is not cut in a ring at the branch point, it can be cut separately if there are several ramet. The insertion depth is about 1B3 or 1B2 and should not be too deep. Family cuttage can be used in cuttage pots, such as large area cuttings must use seedbed, seedling bed soil quality to loose and fertile, good drainage of slightly acidic soil is better. After insertion, a protective shed should be built to prevent the sun and rain (bamboo can be bowed into a scaffolding 50 to 60 centimeters high, covered with plastic film). When the temperature is too high, the film shed must open a corner of ventilation, pay attention to control moisture, should not be too wet. Generally, it can be rooted in about 30 days after spring planting, and can be transplanted in about 2 months. If cutting in summer and autumn, cuttings must choose the new branches that are semi-lignified in the same year, and choose sturdy branches, about 8 cm long, with a heel on the branches. After insertion, it is necessary to keep the seedbed soil moist, pay attention to the heat preservation work when the temperature drops, generally can also take root in about 40 days, and then transplant and cultivate after the next spring is warm.

[striping propagation]: the high branch crimping method can usually be used. The time of high branch pressure should be between May and June. First, select the appropriate branches, determine the high pressure part, use the notching method to horizontally carve one or two circles or annular peeling on the pressed part, the incision reaches to the xylem, then wrap the cut site in a plastic bag or half-half bamboo tube, tie it tightly at the lower end, apply growth hormone on the wound, then fill in the prepared culture soil, and wrap up the bag mouth at the upper end. Keep the soil in the bag moist and fix the high-pressure branches so as not to break. Generally, it can take root in about 40-50 days, and it can be cut from the mother branch and cultivated in the basin after about 2 months. The propagation of Daphne odorifera by water insertion is simple and easy, and the survival rate is also high.

Pot-up process

[selected basin]: Ruixiang should use a slightly deeper round basin or square basin, oval or rectangular basin. The texture of the basin is better with purple sand pottery basin. The potted color can be sunflower yellow or light gray to set off the green leaves and white flowers and produce the effect of drying clouds and supporting the moon.

[soil]: Ruixiang likes to be born in a fertile, loose, well-drained sandy loam, which requires a slightly acidic soil with a pH value between 6 and 6.5. Potted plants should be mixed with rotten leaf soil or sun-dried and weathered pastoral soil plus appropriate amount of rice chaff ash or sand.

[planting]: it should be planted in the pot in April in spring. At this time, the climate is mild and humid, and the temperature difference between day and night is small, which is beneficial to the growth of Ruixiang clothing basin. Planting in autumn is also possible. When transplanting, you should take more lodging soil and prune the branches properly.

Pose shaping technique

[processing]: Ruixiang bonsai should be modeled with wire climbing and pruning. However, attention should be paid to the timely removal of the wire, so as not to cause wire trapping and affect the beauty and growth. Processing modeling should be in the dormant period, can also be carried out after flowering.

[tree shape]: the shape of the Ruixiang bonsai tree should be made into a natural tree shape, the branches should show and stretch, and pay attention to the density and proper density, so as to show the multiplication of flowers, rich color and fragrance, and increase the ornamental effect.

Maintenance and management

[place]: Ruixiang bonsai should be placed in a warm, humid, half-yin and half-yang place. Summer should avoid sun exposure, winter should be placed in the light, air circulation under the south window.

[watering]: Ruixiang is not resistant to moisture, usually the basin soil should be dry, not stagnant water. It is appropriate to water twice in the morning and evening when it is hot in summer, and the watering should be reduced correspondingly in spring and autumn, but during the bud gestation period in autumn, attention should be paid to that the basin soil should not be too dry. When the weather is sunny and dry, you can often spray foliar water, so that the branches and leaves are often wet, which is conducive to growth. in the rainy season, the basin can be moved to the eaves and windows to avoid the rain.

[fertilization]: base fertilizer should be fully applied in winter. It is necessary to apply 2-3 times mature cake fertilizer and water in spring, and the fertilizer and water should not be thick. Stop applying in summer so as not to burn the roots. Apply thin fertilizer frequently in autumn until the buds bloom. Fertilizer and water dominated by nitrogen and potassium are applied in spring, and phosphorus is mainly applied after autumn. After the formation of flower buds, potassium dihydrogen phosphate with a concentration of 0.1-0.2% can be used to spray branches and leaves for external fertilization, but fertilizer and water must be sprayed on the back of leaves to improve fertilizer efficiency and promote flowers and leaves to flourish. Ruixiang avoid using human feces and urine fertilizer.

[pruning]: Daphne is mostly pruned after flowering, and the branches that have flowered can generally be cut short to promote more branches and increase the number of flowers in the following year. Cut off the long branches, cross branches and overlapping branches, and cut off the branches that affect the appearance in time, in order to maintain a certain tree shape.

[turning the basin]: it should be carried out every 2-3 years, preferably after flowering in spring, or in autumn. When turning the basin, you should bring more old soil, the root system can not move much, and some overlong fibrous roots can be cut off properly. The pelvic floor must be fully fertilized.

Winter maintenance

Daphne should be placed in the sun during the day to receive light, and at night it should be moved to a place not less than 5 ℃. In addition, avoid basin soil is too wet, do not apply thick fertilizer, raw fertilizer, avoid being caught in the rain. At ordinary times, we should pay attention to observe the leaves of Daphne odorifera. If the leaves are straight and straight up, it means that the fertilizer is normal; if the leaves are sagging, it is due to too much fertilizer, too often, or too much watering, so we should find out the reasons and take corresponding measures. Watering too much, easy to correct, if the fertilizer is not used properly, you can continuously pour water, let the fertilizer run off from the basin, and then put it in a ventilated place to make the basin soil dry quickly. If you have rotten roots, you need to turn the basin, cut off the rotten roots, wash them with fungicides, and then plant them in the sand to let them grow new roots. The upper branches and leaves should also be cut off accordingly.

The basin soil is mainly sandy soil which is neutral and slightly acidic, in addition, 40% rotten leaf soil, pine needle soil, peat soil or rice husk ash are needed. Base fertilizer should not be applied in basin soil, but liquid fertilizer should be applied at the right time. Liquid fertilizer with soybean water (grind or boil the beans for at least 1 year. Soybean fertilizer is mild and animal fertilizer is irritating) and potassium dihydrogen phosphate solution (high efficient available phosphate potassium fertilizer, diluting crystal particles with 1000 times water) is better.

Daphne is highly resistant to diseases and insect pests, occasionally harmed by aphids and red spiders, which can be controlled with 1200 times of dichlorvos or Baume 0.5 degree stone sulfur mixture. The root system of Daphne odorifera has a sweet taste and is easy to attract earthworms, so when turning over the pot, you can pick up all the earthworms in the pot soil, and usually the flowerpot should not be placed on the soil ground to prevent earthworms from drilling into the bottom of the basin.

The leaves of infected plants showed color spots and deformities, poor flowering and rotten heart. Prevention and control methods: spray Bordeaux liquid 2-3 times before the arrival of high temperature and humidity season, and put it in a cool place. If you find bad heart, you should cut off branches, leaves and flowers in time, and burn them to prevent them from spreading. In particular, Phnom Penh Ruixiang delicate and difficult to raise, afraid of humid, low-pressure climate, cultivation should choose high-cool places to strengthen protection.

There are three main reasons for the defoliation of Daphne odora.

First, in the midsummer season, not only the weather is hot, but also heavy rain, torrential rain and thundershowers, especially thundershowers, are sudden and intense, causing a sharp drop in temperature and easily damaging the capillary roots of Ruixiang.

Second, the sky clears up after the rain, there is stagnant water in the basin, and the plants are steamed under the sun, which hinders the respiration of the roots and is easy to cause rotten roots.

Third, excessive fertilization exceeds the actual needs of the plant, causing toxicity and inhibiting the growth of the plant. Or apply heavy fertilizer that is not fermented and mature, and the root system is damaged by fertilizer.

When there is something wrong with Ruixiang, it is difficult to find out for a while. When its leathery leaves are still bright and green, all the leaves will be in a state of light. For deciduous plants, they should be removed from the flowerpot in time, rinsed with clean water, cut off all the injured and rotten roots, and then planted in the flowerpot with medium-grain river sand and placed in a well-ventilated shade. Often spray plants and flowerpots with fine-eye sprayers or sprayers and keep the surrounding environment moist. After more than a month, very unstretched small leaves will sprout from the branches, and at this time, the plant can be moved to the condition of scattered light, and the plant will undergo weak photosynthesis and produce a variety of organic substances for the metabolism of the plant itself. to restore the plant to normal growth. When the diseased plant had sprouted new roots, it was replanted to the soil with loose and well drained soil, and the PH value was 5.5 / 6.5.

Rotten heart and rotting root

The phenomenon of rotten heart and root in the cultivation of Daphne odora is mainly caused by improper management. Daphne adapts to warm climate, but is not resistant to strong light and likes semi-shade; its root is fleshy, resistant to dry and damp, and is prone to mosaic disease in high temperature and humidity season. Bordeaux solution can be sprayed 2-3 times before the arrival of high temperature and humidity season. During the growth period, we should pay attention to not applying big fertilizer and watering, and keep the basin soil in a semi-wet state. In summer, you should avoid storm, rain and sun rain. If you are suddenly attacked by wind and rain, you will wilt and die immediately. In case of this situation, you should move indoors in advance to take shelter; if you have been hit by wind and rain, you should use a knife on the sturdy branches in time. Cut 1-1.5 cm longitudinally from the cortex to the xylem, so that the excess water and gas in the plant body can be released to facilitate normal growth. If it is found that the leaves of the plant are sagging, the luster is lost, and subtle wrinkles appear, indicating that the root has rotted, if it is first developed, it can be rescued: dig out the seedling, wash the root with clean water, cut off the rotten root, then move it into a new basin, cover the plastic film in a cool place, and two weeks later, if the leaf stands up, it will be saved.
