As an ornamental plant, the greatest feature of Ping an tree lies in its evergreen leaves, but its luxuriant leaves after a period of time may also affect its beauty, so we need to prune it. So what are the methods and techniques for pruning Ping an trees? We learn in detail from two aspects: the pruning of branches and leaves and the shape.

The methods and skills of how to prune Ping an Tree

Although the growth rate of Ping an tree is not fast, after a period of development, it will appear the phenomenon of leaf reduction and height increase below, which will have a certain impact on people's appreciation, so it is very necessary to prune it. Let's learn more about the methods and techniques of how to prune Ping an trees.

First, how to prune the branches and leaves of Ping'an trees

First of all, the most appropriate pruning time is in spring, because the Ping an tree is about to flourish, and many new branches and leaves will grow at the end of spring. Pruning the old branches and leaves can make the new branches and leaves grow more smoothly. However, it can be pruned in the four seasons of each year, and whether the immortal needs to be pruned depends on the situation of the peace tree.

Secondly, when pruning branches and leaves, the main purpose is to truncate the branches and take out the old leaves which are hypertrophic or even yellowed. The cut should be selected at a certain distance from the bud hole on the stem node to avoid seeing the bud eye, and the wound can be smoothed out after pruning.

Second, how to trim the shape of a safe tree

Pruning shape refers to shaping the safe tree, cutting off overdense branches and old branches, and controlling its height by topping. The specific shape to be trimmed can be decided according to one's own preferences. The principle is that it will not affect the normal growth of the safe tree.

How to prune Ping an trees after changing pots

We know that safe trees need to be changed every once in a while, so how should they be trimmed after changing pots? The answer is to try not to prune too much, so it takes time for Ping an trees to adapt to the new soil and environment after changing pots, and there may even be drooping leaves, so it is impossible to judge which leaves need to be pruned.

Pruning can be started about 2 weeks after the change of pots, when it has basically passed the adaptation period, and the old withered branches are also basically revealed, cutting off these redundant dead branches and old leaves will not have a negative impact on the growth of Ping an trees.

Summary: this paper introduces in detail the methods and skills of safe tree pruning, although pruning is not a necessary process, but it can bring many benefits, such as increasing the beauty of Ping an tree and promoting the growth of new branches. so it is beneficial and harmless to prune it, of course, after pruning, we must pay attention to its correct maintenance, the method can refer to the breeding method of Ping an tree, so as to ensure that Ping an tree is more healthy.

Introduction to the correct pruning method of how to cultivate the Happiness Tree

The happiness tree is very suitable for breeding in offices and families. But some novice plant farmers may not be able to raise happiness trees, and some die after a period of time, because they do not master breeding skills, so how can happiness trees flourish? What is the correct pruning method for the happiness tree?

How can the happiness tree flourish?

1. Environmental requirements:

Culture temperature: happy tree likes warm and hot environment, and the suitable temperature for growth is 22-28 ℃. In the hot season, when the ambient temperature is more than 30 ℃, spray water on the leaf surface as much as possible, lower the temperature, or move it to a cool, ventilated place with shade for the summer.

When the temperature drops to about 10 ℃ in autumn, the plant must be moved to a warm place indoors for maintenance. Throughout the winter, the temperature should be kept at 8 ℃, and the lowest temperature should not be less than 5 ℃. You can move the plant to an air-conditioned or electric heater room to ensure that the room temperature is not less than 8 ℃, so that it can survive the winter safely.

Culture humidity: for housekeepers, spray water on and around the leaves of the plant as much as possible to increase the relative humidity of the air. The happiness tree likes the wet environment, too dry is bad for its growth, but it should reduce the number of water spraying in winter.

Aquaculture lighting: happy trees like light, but also slightly able to withstand shade, full sunshine, semi-overcast environment can be, in summer, it is best to avoid the bright light at noon. When placed at home, it is best to put it behind the glass window, so that you can not only get enough light but also effectively avoid the direct light of strong light. In winter, we should pay more attention to supplement the demand for light of the plant.

2. Fertilizer and water management:

The demand for water in the happiness tree is moderately moist, and too dry or too wet will cause the roots of the plant to rot. During the growth period, water should be fully supplied to keep the basin soil moist, but it is not easy to be wet and waterlogged. For outdoor plants, the stagnant water in the basin should be emptied in time after the rain in the rainy season.

Fertilizer can use nitrogen, phosphorus and potassium balanced slow-release fertilizer, generally combined with changing pots in spring, the fertilizer will be mixed into the substrate, using 3000 times of potassium dihydrogen phosphate and 5000 times of urea every month, diluted and watered with water. In addition, it can be drenched with clean water every time you see the basin soil dry.

Nitrogen-based fertilizer was applied once a half month in the growing season to make the branches strong and the leaves bright. However, nitrogen fertilizer should not be applied too much, otherwise the petiole and Internode will become longer and the plant type will be loose.

In winter, to make the matrix partial to some, as long as the leaf tip does not appear sagging symptoms can not be watered. In order to enhance the resistance of plants to low temperature in winter, 5000-fold solution of potassium dihydrogen phosphate can be sprayed once a month.

3. Pest control:

The main disease of Happy Tree is leaf spot, and the main pests are shell insects, mites and aphids. Caregivers in the usual maintenance and management to pay attention to the observation of shell insects, more water spray. Pay attention to check whether there are aphids on the new leaves when they grow.

Spraying 800 times of carbendazim or 800 times of chlorothalonil every half a month to prevent the occurrence of leaf spot. Plants should not be maintained in an overly dark environment.

Symptom of leaf spot disease: fallen leaves

The reason of falling leaves: the reason of falling leaves of happiness tree should be analyzed in detail. First, if it is winter, the leaves turn yellow from the bottom up, and then fall, which is caused by low temperature; second, if in the vigorous growth season, the leaves turn yellow from the bottom up, and then fall, this is the phenomenon of nitrogen deficiency caused by insufficient absorption of nitrogen fertilizer by plants; third, long-term maintenance of plants in dark places will also lead to the fall of middle and lower leaves.

Solution: for leaves falling due to low temperature, caregivers are needed to raise the temperature around the plants, and yellow leaves caused by nitrogen deficiency are needed to improve the nitrogen nutrition of the plants. if the leaves are caused by dark light, the plants are cultured in a suitable light environment.

4. Points for attention:

The shape of the happiness tree is beautiful, generally without heavy pruning, withered branches and diseased branches can be cut off at any time. The room temperature should be kept at no less than 8 ℃ in winter, otherwise chilling injury or even death of the whole plant would occur easily.

Happiness tree is a light-loving plant, but also slightly able to tolerate shade, full sunshine, semi-shady environment can be, to avoid strong summer light. When placed indoors, it is best to put it in front of a window with sufficient light or on the balcony. If you put it in a dimly lit room for a long time, it is easy to cause fallen leaves. Family potted plants can be placed in front of the window or in front of the balcony during the overwintering period to allow them to receive more light.

When potted happiness trees, the substrate with loose, breathable and good drainage should be selected, and the PH value of the substrate is 5.5-6.0. The fertilizer needed for potted happiness tree is nitrogen: phosphorus: potassium: calcium: magnesium = 1009.

The pruning method of Happiness Tree

(1) coring: it is also called cutting off the tip and topping, which is to pinch or cut off the top of the main stem or side branch of the flower plant by hand, so as to break the top advantage of the plant, promote the germination of its lower axillary buds, inhibit the excessive growth of branches, and promote the plant to be more branched. and form a multi-flower head and a beautiful plant shape.

(2) wiping head: large flowers such as rubber tree, thousand-year-old wood, goose palm wood, Wang Dai powder leaf, etc., the plant is too tall and difficult to grow indoors, so it needs to be pruned or wiped. The upper part of the plant is usually cut off before the new branches germinate in spring, which is called wiping head. The height of the trunk when wiping your head depends on the type of flowers.

(3) thinning: including pruning branches, leaves, buds, flowers and adventitious buds. When the growth of flower plants is too exuberant, resulting in branches and leaves too dense, part of the branches should be thinned timely, or the leaves that are too dense should be removed to improve ventilation and light transmission conditions, so that flowers grow stronger and flowers and fruits are more colorful.

(4) the flowers of Happiness Tree are erect, terminal, nocturnal, calyx teeth ovate-lanceolate, bracts linear-lanceolate. When we prune the happiness tree, we have to prune it the way we want it to grow.

Matters needing attention in cultivating Happiness Tree

(1) temperature precautions: the temperature is controlled at about 20 degrees Celsius in the daytime and 28 degrees Celsius at night, whether it is too high or too low, it will affect the development. In general, in winter, the temperature should be controlled at a certain level, usually about 10 degrees Celsius.

(2) humidity precautions: the humid environment is the environment that the happiness tree likes. The way to control humidity is to spray water on the leaves to ensure humidity. Summer flowers should be sprayed at least twice a day, and do not spray water at noon in summer, otherwise it will cause harm to the plants themselves. But be careful not to get too wet, because otherwise too wet or too dry will lead to plant death or yellowing

(3) Lighting precautions: the Happiness Tree relatively likes the sun, and there will be no problem if it is not exposed for a long time, but if you want him to grow big and healthy, then you need the city to give him light and daily scattering. If you want to keep it in winter, you'd better put it on the balcony to accept the sun.

(4) points for attention in watering: general watering for soil water, then the standard is not dry and not watered.

(5) pruning precautions: the happiness tree is mainly placed at home for viewing, so it needs pruning in the process of growth. The main purpose of pruning is not only to take care of its appearance, but also to cut off its dead and diseased leaves.

The efficacy of happiness tree

(1) Happiness tree can beautify the environment.

Beautifying the environment is one of the important functions of the happiness tree. After it is made of potted plants, it is suitable to be placed on the balcony or in the foyer, which can add some green to the indoor environment and make the family feel vibrant. In addition, it can also purify the air, remove harmful substances in the air, and provide a good living environment for human beings.

(2) Happiness tree can cure the injury caused by fall.

In addition to being able to watch the happiness tree, its annual seeds and leaves and roots can also be used as medicine, with many functions such as clearing away heat, cooling blood and detumescence. Usually, its happiness tree can be used for the treatment of human injury caused by falls. During treatment, its root slices can be fried with clear water, and then taken orally directly, which can play an important role in promoting blood circulation, removing blood stasis and reducing swelling and pain.

(3) Happiness tree can cure snakebite.

Happiness trees can clear heat and detoxify, and can treat snakebites. Usually, after people are accidentally injured, there is no need to panic. They can take off the leaves of happiness trees, mash them into mud with tools, and then apply them directly to the injured parts. After changing dressing once a day for two or three days, the poisoning symptoms caused by snake bites can disappear completely.

"Culture methods and points for attention of Yushu"

Crassulaceae, green lock dragon genus. [morphology] evergreen succulent plant, 45-75 cm tall, stem semi-lignified. The leaves are opposite, fleshy, broad-oval, entire, 3-5 cm long and 1-3 cm wide. The leaf color is dark green and glossy. After illumination, the leaf margin turns red. Horticultural varieties have variegated leaves and colored leaves. [habits] originated in South Africa. It likes warmth, drought, light and half shade, so it grows best under the condition of bright scattered light. Like fertile, loose, draining and breathable sandy loam. [propagation] cutting propagation. Both branch and leaf cuttings are easy to take root, and they can survive by water insertion. The cutting time is from May to September, take 5-10 cm branch or 1 leaf, insert it in plain sandy soil, pay attention to moisturizing, and root after a week. [cultivation] 2 parts of garden soil and 1 part of rotten leaf soil were used in basin soil, and the culture soil was prepared by adding proper amount of river sand. After potting, the seedlings are watered, placed in a shaded place, and placed in a bright place after survival, so as not to let the sun shine directly. Pay attention to cool ventilation in summer. In order to make the plant shape plump and compact, usually the fat and water should not be too large, and the basin soil should be dry and wet. Enter the room at the end of autumn to keep warm, the room temperature should be above 7 ℃. Don't water too much in winter. The basin should be turned over and the soil changed once a year in spring. Although Yushu is easy to propagate, easy to plant and easy to manage, it is still common for Yushu on the balcony of some households to face the wind in spring, summer and autumn, but it wilts and turns pale after winter, and even becomes a "shirtless chicken". This is mainly because flower growers only see the easy side of Yushu and ignore its fragile side. After entering the severe cold, they still put it on the open balcony, allowing it to be attacked by the cold wind, causing Yushu to suffer frost damage. After the freezing injury, the fleshy leaves and tender stems of Yushu began to show the same trauma as scalded by boiling water, and then gradually became soft, shriveled, and finally fell off, leaving only the naked main stem in serious cases. Therefore, it is very important to do well the overwintering work of potted jade trees on the balcony, and we should mainly grasp the following links: 1. Move the basin into the room in time. After entering winter, Yushu should be moved to an indoor thermal insulation that can maintain 7 ℃ to 10 ℃. In warmer days, Yushu can be moved to the balcony at noon to bask in the sun, and the night still moves indoors. 2. Control the dry humidity of the basin soil. In winter, the basin soil is mainly slightly dry, and timely spray fine mist to replenish water. In general, there is no need to directly water the basin soil. 3. Move into the greenhouse to keep warm. Conditional pots can be moved into the greenhouse, no conditions can also be sealed with plastic film cover, but need to pay attention to the humidity in the cover, found that the water is too wet, it is necessary to remove the cover in time to change air to prevent rotten leaves. 4. If Yushu has suffered frost damage due to the mistake of anti-freezing measures in the early stage, do not discard the plant easily. As long as the frozen leaves and twigs are removed, the full main stem is preserved and fertilized properly in the coming spring, new branches and leaves can still germinate on the main stem. Generally, after 1 to 2 years of cultivation, it can develop into a perfect jade tree. First, when Yushu is cultivated, it should be watered as little as possible in summer. its roots are fleshy and the leaves evaporate slowly. In summer, you can usually see the soil dry and watered. No stagnant water. Summer

Culture methods and matters needing attention of Yushu part II

Introduction to the Culture methods of Yushu

A warm, dry and sunny environment. Not resistant to cold, afraid of strong light, slightly resistant to shade. The sandy loam with fertile soil and good drainage is better. The winter temperature is not lower than 7 ℃.

1. Pot soil requirements: the most suitable for changing basin soil and planting time is early spring. The basin soil should be loose, fertile and well drained. 2 parts of rotten leaf soil or peat soil, 2 parts of garden soil, 3 parts of coarse sand, 1 part of limestone and gravel, or 3 parts of rotten leaf soil, 3 parts of garden soil, 3 parts of coarse sand, 1 part of bone powder and 1 part of plant ash can be selected as basin soil.

two。 Temperature requirements: the temperature between 20-30 degrees is most conducive to the growth of Yushu. Spring and autumn are the most suitable growing periods for Yushu. Yushu is afraid of bright lights. When the temperature is high in summer, you should pay attention to keep the plants in the shade to avoid direct sunlight. When the environmental temperature of Yushu is higher than 38 degrees, the growth rate will begin to slow down and even enter a short period of dormancy. In winter, we should pay attention to the temperature, put the plant in the greenhouse, preferably in a place with light. The room temperature should not be lower than 7 degrees. Below 0 degrees will cause the plant to freeze to death. Yushu, which is in its growing period, needs shade except for the high temperature and heat in summer. All should be kept in a sunny place.

3. Watering requirements: when Yushu is in its growing period, the watering frequency needs to be controlled every two to three days. Can not have the phenomenon of stagnant water should also avoid the basin soil is too wet. Yushu should be cultivated in summer to control the number of watering, and to strengthen ventilation, so as to avoid the phenomenon of fallen leaves. It is necessary to reduce watering when raising Yushu in winter. The specific principles depend on the dry and wet conditions of the basin soil. Micro-drying is better for basin soil.

"Yushu Culture method"

Strong light, slightly resistant to shade. The sandy loam with fertile and well-drained soil is better. The winter temperature is not lower than 7 ℃.

Yushu is planted or changed in the soil basin before it begins to grow in early spring. The basin soil should be loose, fertile and well drained. Generally, 2 parts of rotten leaf soil or peat soil, 2 parts of garden soil, 3 parts of coarse sand, 1 part of limestone and gravel, or 3 parts of rotten leaf soil, 3 parts of garden soil, 3 parts of coarse sand, and 1 part of bone powder and plant ash were used as basin soil.

The suitable temperature for Yushu growth is 20-30 ℃. Spring and autumn are suitable growth periods. When it is hot in summer, it should be shaded or placed in the shade of trees to avoid strong direct sunlight. When the temperature exceeds 38 ℃, it grows slowly or enters short dormancy. In winter, it should be kept in the greenhouse or in the sunny place indoors. The room temperature should be kept at 7-10 ℃, and the minimum should not be less than 5 ℃. If it is as low as 0 ℃, it will freeze to death. During the growing period, except when it is hot in summer, it should be placed in a sunny place.

During the growing period, Yushu should be watered every 2-3 days, but the basin soil should not be too wet, let alone stagnant water. When it is hot in summer, watering should be strictly controlled and ventilation should be strengthened, otherwise it is easy to cause fallen leaves. Watering should be reduced in winter, and the basin soil should be slightly dry. Topdressing fertilizer should be applied during the growing period, generally applying rotten thin cake liquid fertilizer 2 or 3 times a month. Adequate base fertilizer should be applied before soil change or planting. Mature organic fertilizer, such as chicken manure, pigeon manure, bone meal, large manure and all kinds of cake fertilizer, can be added to the culture soil as base fertilizer. In order to keep the plant shape plump, the fat and water should not be too large, so as not to cause overgrowth.

Plant Culture methods (streamlined)

Leave it 20-50 cm (height depends on your appreciation) to cut dry, the truncated branches can be inserted into the river sand and placed in the shade to ensure sufficient air humidity, about 2 months later can become a new black King Kong.

When planting black King Kong flowers in pots, it is appropriate to use 1 part of rotten leaf soil, 1 part of garden soil and 1 part of river sand, and add a small amount of base fertilizer to form culture soil. It grows very fast in a hot and humid environment, and a leaf can be produced every 5 mi 10 days. During this period, adequate fertilizer and moisture must be ensured. Generally, liquid fertilizer or compound fertilizer is applied twice a month, while keeping high soil moisture. After autumn, gradually reduce the number of fertilization and watering, in order to promote plant growth and enrichment, conducive to overwintering.

The breeding method of Black King Kong

① lighting: except for shading when the summer sun is particularly strong, try to give sufficient light at other times, otherwise the leaf color is not good.

② temperature: like high temperature, the suitable temperature is between 20 and 32 ℃, and the overwintering temperature should be kept above 10 ℃.

③ humidity: do not like too dry environment, it is important to keep moist, this is related to the bright color of the leaves.

④ watering: if you maintain it indoors, you must keep it dry and wet alternately. Once dry, water thoroughly!

⑤ fertilization: apply less frequently, do not apply thick fertilizer or raw fertilizer.

⑥ pruning: resistant to pruning, short pruning can be assured if the branches are too long or the plant type is not good.

⑦ breeding: combined with pruning, semi-lignified branches can be cut and propagated with a high survival rate.

⑧ pest control: it is common for red spiders to harm leaves, and can be sprayed with triclofenac, Nisolang, pyridaben and other special insecticides. Matters needing attention in breeding of Black King Kong

1. The temperature is too low: the suitable temperature for the growth of Black King Kong is 20-30 ℃, and the most luxuriant growth is at 25-30 ℃. The growth is poor when it is less than 10 ℃, and it is easy to suffer frost injury when it is less than 0 ℃. If you are hit by a cold wind indoors, there will be yellow leaves and fallen leaves.

two。 The light is too dark: black King Kong's growth environment requires light of about 10000-20000 lux. When the light is too low, there will be yellow leaves and fallen leaves accompanied by poor ventilation.

3. Improper watering: black King Kong likes water, but is not resistant to water stains, when there is a phenomenon of waterlogging, when the root can not get oxygen, there will be yellow leaves, fallen leaves. Watering should follow the principle of "dry and wet". Don't water too often. Second, the safe tree

1. Temperature: ping an tree likes the hot and humid environment, the best temperature is 22 ℃ to 30 ℃. When the temperature is more than 32 ℃, it is necessary to build a shed to shade and spray water on the leaves of Ping an tree to humidify and cool down, so that it can maintain exuberant growth. The lowest temperature in winter should not be lower than 5 ℃.

two。 Watering: ping an trees like wet soil and water appropriately every morning and evening. In winter, you should spray more water and less water. There can be no stagnant water in the basin.

3. Light: ping an tree needs better light, but it is more shady. It is suitable for the maintenance of semi-overcast environment, and its light demand varies with age. if the light is too strong, it is easy to cause leaves to yellowing and lose mind, and reduce its due ornamental value.

4. Fertilization: fertilize the safe tree once a month. After autumn, phosphate and potassium fertilizer should be applied twice in a row, and all forms of topdressing should be stopped in winter.

5. Soil: small plants change pots once a year, large plants change soil once every two years, loosen the soil once a month in the growing season, turn the basin to change soil time, preferably in spring.

6. Diseases and insect pests: aphids are easy to grow on the young leaves and new buds of Ping an tree. After spreading plant ash, rinse with clean water; spray neem leaf juice, which can effectively kill insects; spray imidacloprid wettable powder 2000 times.

Matters needing attention

1. A small number of diseased leaves should be removed and burned in time to avoid yellowing and withering of the whole leaves, resulting in a large number of fallen leaves.

two。 If there is stagnant water in the basin soil, it is easy to lead to plant yellowing, lower leaves yellowing and falling off, and in serious cases, it will cause rotten roots and death.

"how to raise Yushu?"

Wind is an idiom, Yushu City, Sichuan Province. In fact, Yushu is just a kind of tree. Yushu, also known as swallow palm, suitable for potted plants, can be displayed on the balcony or embellished on several tables in the room, which is very elegant and elegant. Next, Huamu China Network will introduce to you the breeding methods of Yushu:

The cultivation method of Yushu how to raise Yushu

I. Propagation methods of Yushu

The common propagation method of Yushu is cutting propagation. Generally, the side branches with leaves are selected from the plants with good growth potential and side branches, and the cuttings are 8-12 cm long and dry in a cool and ventilated place for 1-2 days, so that the incision is slightly dry, and then inserted into the breeding sand bed; the leaves of the main stem can also be removed, and after the incision is slightly dried, it is inserted into the sand bed to maintain 20-25 ℃ and suitable humidity to take root in about half a month.

Second, the substrate needed for the growth of Yushu

The hall and the office hall are all distinguished, elegant and beautiful. Yushu can not only release oxygen during the day, but also absorb indoor carbon dioxide at night, which is incomparable to most indoor flowers. Therefore, the small potted Yushu is very suitable for maintenance in the bedroom. Seeing is believing, let's enjoy the picture of Yushu first.

Many friends do not know how to raise Yushu, do not know the breeding method of Yushu, the following editor will give you a brief introduction.

The Culture method of Yushu

Succulent subshrubs, preferring warm, dry and sunny environments. Not resistant to cold, afraid of strong light, slightly resistant to shade. The sandy loam with fertile and well-drained soil is better. The winter temperature is not lower than 7 ℃.

Yushu can not only release oxygen during the day, but also absorb indoor carbon dioxide at night, which is incomparable to most indoor flowers. Therefore, the small potted Yushu is very suitable for maintenance in the bedroom.

Cuttings are carried out in spring and autumn, with fast rooting and high survival rate. The optimum cutting temperature was 16 ℃ and 21 min, and rooting 3 weeks after cutting with tender techniques. Put on the pot when the root is 2mi 3cm long.

"the cultivation of Yushu"

Redness, swelling, pain, such as splashing into the eyes can also lead to blindness. Although the appearance of Yushu is not amazing, because this succulent plant has strong posture, drought tolerance, easy cultivation, plump branches and leaves, green leaves all the year round, and the inflated stem nodes on its stem have the posture of an ancient tree stump, so nowadays, potted Yushu is more common on the balcony of urban and rural residents in the south of the Yangtze River.

Yushu, also known as swallow palm, sedum tree and so on, is a plant of crassulaceae and green lock dragon. Originally from South Africa, it is now cultivated all over the country. Evergreen shrubs. Stem Terete, grayish green, articulate. Leaves opposite, flattened, fleshy, elliptic, entire, apex slightly acute, base rounded clasping stem. It's red. Like warm and dry, sunny and ventilated. Like loose sandy cultivated soil. Avoid getting the soil too wet. Cutting is the main method of propagation. Twigs or leaves can be used for cutting. The cuttings should be dried in the shade before insertion. It can be cut in moist yellow sand or perlite in spring or autumn.

Swallow palm has fewer diseases and insect pests, and sometimes it will encounter anthracnose and leaf spot disease. It can be sprayed with 1000 times of methyl topiramate wettable powder. If the indoor ventilation is poor, the stems and leaves are vulnerable to shell insects. It is found that pests should be washed manually immediately, and when the damage is serious, 40% omethoate emulsion 1000 times can be used to spray and control.

The cultivation and management of swallow palm is simple and extensive, but there is indeed some work to be done in order to achieve plump and robust plant shape and full bloom of trees as scheduled. First of all, the swallow palm grows faster, change the basin every spring, add fertile soil, and put it in a sunny place for maintenance. Apply thin fertilizer and water every 10 days and half a month, and water every 2 to 3 days, so that you can see dry and wet. High temperature in midsummer, swallow palm in a semi-dormant state, afraid of strong light burning leaves, at this time to do a good shade maintenance. Stop fertilizing in summer and pay attention to ventilation to prevent leaves from yellowing and falling off. If it rains heavily, avoid torrential rain, so as to avoid stagnant water in the roots and death. When autumn turns cool from August to October, the palm of the swallow begins to grow again. It is necessary to strengthen the light again and remove the shading equipment. At this time, fertilization and watering are in principle the same as in spring. Frosts Descent before entering the greenhouse, put it indoors in the sunny place, stop fertilizing, watering should be controlled, basically once a month, the amount of water is 1/2 of that in summer. Swallow palm is not cold-resistant in winter, the temperature should be kept above 7 ℃. Shaping and pruning once a year, when changing pots in spring or entering the greenhouse at the end of autumn, in order to keep the plant shape simple and elegant all the year round.

How can Yushu blossom?

Swallow palm, also known as Yushu, crassulaceae, etc., for crassulaceae, green lock dragon plants. Common cuttage propagation can be carried out during the growth period, and it can take root about 3 weeks after cutting, which is very easy to survive. As far as the author knows, the cultivation of swallow palm is more common in Huang-Huai area, but there are few blossoms. From the experience of planting swallow palms for more than ten years, if we want swallow palms to blossom, we must have a certain growth age and provide certain growth conditions. Now the flowering situation of the palm of the swallow planted by myself is introduced as follows.

Three pots of swallow palms blossom in the past two years, including two pots at the age of 5 and one at the age of 6. All show clusters of buds in early November, some buds open in early December, five petals, white, elegant and chic, bloom in the first and middle of March, the florescence is about 100 days, and the fragrance is sweet to the nostrils.

Although Yushu is easy to propagate, easy to plant and easy to manage, it is still common for Yushu on the balcony of some households to face the wind in spring, summer and autumn, but it wilts and turns pale after winter, and even becomes a "shirtless chicken". This is mainly because flower growers only see the easy side of Yushu and ignore its fragile side. After entering the severe cold, they still put it on the open balcony, allowing it to be attacked by the cold wind, causing Yushu to suffer frost damage. After the freezing injury, the fleshy leaves and tender stems of Yushu began to show the same trauma as scalded by boiling water, and then gradually became soft, shriveled, and finally fell off, leaving only the naked main stem in serious cases.

"Culture methods and matters needing attention of Cymbidium"

Lily, editor of Nanhuamu Network, explains how to raise the orchid. If you want to master the daily maintenance skills of the orchid, you must first understand its growth stage. In a year, the growth and development of the orchid roughly goes through the following stages:

New buds sprout from February to March (new calendar, the same below)

New buds unearthed from April to May

From June to July, the new leaves elongated; from August to September, the new leaves continued to elongate to form new orchid plants; germinated and grew new roots to form independent roots; from October to November, the new orchid plants gradually matured, Reed heads increased, and flower buds differentiated.

From December to January of the following year, Gladiolus elongated.

It blossoms in February.

The breeding method of Cymbidium

(1) ramet propagation. This method is simple and reliable, blossoms quickly after dividing plants, and can preserve the original characteristics of the variety. It is a propagation method to divide the pseudobulbs of Cymbidium into single or 2-3 groups and plant them independently in order to achieve the purpose of proliferation. The ramet propagation of Cymbidium is best carried out in the dormant period, that is, the dormancy period before the new buds are unearthed, before the new roots grow, or after anthesis. Separate orchid plants should be viewed, cut off rotten roots and withered leaves. Disinfection method

The 10~15min of the root of orchid plant can be soaked in 800-1000-fold solution of 70% methyl topiramate and slightly dried after soaking, then it can be replanted. Although ramet propagation is simple and easy, and can maintain the inherent characteristics of varieties, so that many valuable varieties can be preserved, but after all, the ramet reproduction coefficient is small, it is difficult to meet the needs of large-scale production and market. Therefore, we must explore more scientific and advanced methods of reproduction. The tissue culture propagation of Cymbidium is a more advanced propagation method which can meet the needs of production and market.

(2) tissue culture. Tissue culture is an advanced science and technology developed on the basis of cell theory and plant cell totipotency theory. At present, it is constantly popularized in the field of forest reproduction. According to the analysis of relevant statistical data, the tissue culture propagation of herbaceous plants is easier and the success rate is higher than that of woody plants. The propagation of tissue culture of Cymbidium is an advanced method of breeding Cymbidium by using advanced equipment and modern science and technology. After tissue culture, Cymbidium has strong resistance, less diseases and insect pests, high survival rate, and can be mass produced.

Culture methods and matters needing attention of Cymbidium

First, the substrate for cultivation

Chinese traditional potted magnolia often uses humus soil under the forest of its origin, which is called "orchid mud" by locals. This kind of soil is rich in humus, loose and non-adhesive, and is often slightly acidic, so it is an excellent potted soil for cultivating Cymbidium. The cultivation of Cymbidium in the north is generally made of 5 parts of rotten leaf soil and one part of sand and mud. It was also mixed with 4 parts of humus, 2 parts of peat soil, 2 parts of slag and 2 parts of river sand.

Second, seedling division and disinfection.

When dividing the basin, first use the five fingers of the left hand to grasp the base of the orchid seedling, turn the basin upside down, and gently tap around the basin to separate the basin from the basin soil, and then carefully tap the soil to shake off the soil. Carefully clean the orchid root, cut off the rotten root, broken root, withered leaf and dry false bulb, then rinse it with clean water and disinfect the orchid root in 1000-fold solution of topzine or potassium permanganate solution. Kill germs near the wound.

Third, put on the pot.

After the basin is selected, before planting, cover the drainage hole of the basin floor with large pieces of broken tiles, spread with window screen, and then cover with coarse particles of mountain mud.
