Pot culture methods and matters needing attention of Milan flower

Rice orchid is a kind of evergreen shrub, small tree, alias Magnolia, rice orchid, tree orchid, fish orchid and so on. Milan is native to Fujian, Guangdong, Guangxi, Yunnan and other provinces of China, and it is also distributed in Southeast Asia. It is a common fragrant ornamental plant. Now the editor of Qiannong Network will take a look at the breeding methods of Milan with you.

Growth habits of Milan Flower

Milan flowers prefer warm, humid and sunny environment, not cold-resistant, slightly shade-tolerant, the soil is the best in loose and fertile slightly acidic soil, and the winter temperature is not lower than 10 ℃.

1. Milan flowers like to be warm, sunny and fat. The suitable temperature for growth is 20 ℃ ~ 25 ℃. Under normal circumstances, when there is plenty of sunshine and a high temperature (about 30 ℃), the flowers will have a strong fragrance. If it is placed in shade in summer and a large amount of nitrogen fertilizer is applied at the same time, it is one of the main reasons why Milan flowers do not blossom or blossom less and have a light fragrance. Therefore, during the period of growth and development, Milan flowers need to be maintained in a sunny place outdoors, and should pay attention to applying more liquid fertilizer containing more phosphorus, preferably with crushed bones, fish bones, chicken bones, etc., often supplemented with chemical fertilizer containing more phosphorus or fermented rice water, which is helpful to pregnant buds, and blossoms more, golden in color, and fragrance.

2. Milan flowers like to be moist and should be watered properly during their growth. If too much watering, easy to lead to rotten roots, leaves withered off; flowering period too much watering, easy to cause falling flowers and buds; watering too little, it will cause leaf edge withered, withered buds. Therefore, when the summer temperature is high, in addition to watering water 1 / 2 times a day, branches and leaves are often sprayed with clean water and sprinkled to the ground to improve air humidity. At the same time, fertilization should also be appropriate. As Milan blossoms more often in a year, after each blossom, it should be fertilized with 2 or 3 fully mature thin liquid fertilizer in time, so that it can blossom continuously and have a strong aroma. Milan flower likes acid soil, so it is suitable to choose rotten leaf soil as the main culture soil in pot cultivation. During the peak growth period, 0.2% ferrous sulfate solution is sprayed once a week, and the leaves are green and flowers are numerous.

Propagation techniques of Milan Flower

Rice flowers are commonly used for cuttage and high-altitude striping propagation.

The main results are as follows: 1. there are old branch cutting and tender wood cutting. the former uses the old branches of last year as cuttings from April to May, while the latter selects semi-lignified branches of the same year from June to August. The standard of collecting tender cuttings is that the leaves at the end of the branches are thick, the color is green, and the axillary buds are full. The cuttings are about 10 cm long, the upper 2-3 leaves are retained, and all other leaves are removed to reduce water evaporation and nutrient consumption and flatten the incision. Cutting media can use river sand, expanded perlite, peat, vermiculite and so on. When cutting, you can first use bamboo chopsticks to drill holes in the soil, the spacing is about 5 cm, and then insert the cuttings into the hole, the depth is about 1x3 of the cuttings. After insertion, use your fingers to compact the soil, so that the soil and cuttings are closely combined, and fully watered. Set up a shade shed to maintain a ventilated and moist environment. The speed of rooting of cuttings is closely related to the soil temperature. When the bottom temperature is high, the rooting is fast. When the base temperature is 30C~32 C, it can take root 40 days after cutting, and it takes 50-60 days for 25 C to take root. However, the bottom temperature is high, the leaf evaporates quickly, and the metabolism of cuttings is in an active state. At this time, if the humidity is low, it is easy to cause the cuttings to fall leaves. Once the cuttings are defoliated, there is no hope of survival. Therefore, high temperature must also ensure high humidity, usually maintaining a relative humidity of more than 85%. Before cuttage, the base of cuttings was soaked in vermiculebutyric acid of 20PPm~25PPm for 12 hours, or indole acetic acid of 50PPm for 15 hours, which could promote rooting.

2. High-altitude pressing can be done from May to September, but the best time is the Meiyu weather in June, when the survival rate of high pressure is high and takes root quickly. generally, Milan flowers with high pressure in the first ten days of June can take root one after another after 40 days. The specific method is: select annual Lignification sturdy branches, stem diameter 0.5 mm. Make a circular peeling 20 cm away from the bifurcation, the width of the ring is about 0.5 cm, and the depth is to see the xylem, then apply it to the ringed part with moss or wet soil, and then wrap it with plastic film to keep the moss moist all the time. After taking root, cut away from the mother, first slow the seedling in the shade place, and then plant it in the basin. By using this method, the survival rate is high, and the mature seedlings bloom quickly.

Cultivation and Management of Milan Flower

Although the Milan flower has strong shade tolerance, it is not resistant to long shade, especially when the potted rice flower is in full bloom, it can not be placed indoors for a long time. When it blossoms, it can be moved outdoors after 4: 00 p. M. and indoors before 9: 00 a. M. to make it accept sunlight and accumulate nutrients for the emergence of new branches and new flowers. When moving indoors in winter, you should also make it receive as much light as possible.

Although the requirement of Milan flower on soil is not strict, it is suitable for sandy loam which is rich in humus, fertile and slightly acidic. When preparing basin soil, 2 parts of peat soil, 1 part of Gaza, 2 parts of fertile garden soil, 2 parts of compost soil and 1 part of Gaza were mixed.

After the seedlings are in the pot, when they grow to 20 cm ~ 25 cm high, the heart can be removed to promote the formation of lateral branches and the formation of a crown as soon as possible. at the same time, the plant height can be controlled and the number of flowers can be increased.

When planting flowerpots in Milan, it is necessary to ensure good drainage and watering according to the dry and wet climate, not only to keep the pot soil moist but not to have too much water for a long time. Maintaining high air humidity is beneficial to the growth of Milan flowers, and it is best to spray water on the leaves once or twice a day in the period of drought and vigorous growth.

The Milan flower has luxuriant branches and leaves, and during the growing period, it constantly produces new branches and forms spikes, so it needs sufficient fertilizer. If the fertility is not enough, the amount of flowers will decrease significantly. To this end, after the spring begins to grow, fertilizer should be topdressing in time. Topdressing with rotten cake fertilizer or sesame sauce residue water is better, Milan flowers can not stand thick fertilizer, so fertilization should grasp the principle of frequent application of thin fertilizer, especially when topdressing in spring, do not apply thick fertilizer. Topdressing should be applied once every 10 days, and an appropriate amount of calcium superphosphate should be added in fertilizer and water.

When it is hot in summer, to put the Milan flowers in a shady place, you can put them on the edge of the shade shed, so that you can not be exposed to strong light and get more sunshine. Because too strong direct light has an inhibitory effect on the growth and development of Milan flowers, and too shaded, it is also easy to cause Milan flowers to grow, grow weak and reduce the number of flowers.

According to the temperature requirements of Milan flowers, potted Milan flowers generally can not be moved outdoors until Grain Rain, but in autumn they have to move indoors before Frosts Descent to spend the winter. During the overwintering period, it is suitable to keep the room temperature at 10C~12 C. too high room temperature is easy to cause continued growth, which is disadvantageous to the growth and development in the second year. However, when the temperature is too low and falls below 5C, it is easy to cause frost damage. Milan flowers spend the winter indoors, the leaves are easily stained with dust, affecting its normal photosynthesis, so every once in a while, it needs to be washed.

Plastic surgery should be carried out from the beginning of the seedling to retain a section of the trunk 15 cm ~ 20 cm high, and do not let the main branches come out from the ground. Because Milan flowers produce spikes in the armpits of new leaves, they are generally not pruned. In order to control the shape of the tree and add new branches, you can pick the heart before the new branches grow, or prune them in combination with cuttings.

Control of Diseases and insect pests in Milan Flower

The diseases of Milan flower include stem rot, anthracnose, etc., and insect pests include white wax cicada, aphids, red spiders, shell insects and so on.

1. Stem rot: occurs on the stem of Milan flower. At the beginning of the disease, it was a small black spot, expanded into strips, dark brown, and caused plant death after a week around the stem. At the initial stage of the disease, 0.5%-1% Bordeaux solution can be used to smear the branches; it can also be smeared with 1-2 degree Shiliu mixture or 70% Topol 800 times aqueous solution, and the effect is also good.

2. Anthrax: anthrax is the main disease of Milan flower, which mostly occurs from June to October. In the early stage of the disease, the disease spot invaded from the leaf tip and leaf edge, making the leaf tip brown. It can occur on the leaf, petiole and stem of the plant. Prevention and treatment: diseased leaves and diseased branches should be removed in time and ventilation conditions should be improved. It can also be sprayed with potassium permanganate 1000-1200 times aqueous solution.

3. Red spiders: aphids can be sprayed with 1000-1500 times dimethoate aqueous solution or 1200 times dichlorvos aqueous solution.

Key points of Culture of Milan Flower

1. The temperature should be suitable: the Milan flower likes to be warm. The higher the temperature is, the more fragrant the flowers will be. Generally speaking, when the temperature is above 30 ℃, the flowers will smell good when exposed to sufficient sunlight. On the other hand, in the environment below 30 ℃, if they are in the shade of insufficient light, the flowers will not have the fragrance when the temperature is high. The suitable temperature for raising Milan flowers is between 20 ℃ and 35 ℃, and it can blossom as many as 5 times from June to October.

2. There should be plenty of light: Milan flowers should be placed in sunny places throughout the year. If the Milan flower is placed on a well-lit and well-ventilated garden or balcony, and the light is more than 8 hours to 12 hours a day, it will make the leaves of the plant green, the branches grow stout, the number of flowering is more, the flower color is bright yellow, and the aroma is also rich. If we let the Milan flower in the environment of lack of sunlight and shade, it will make the plant branches and leaves grow long and thin, reduce the number of flowering, and the aroma is light.

3. Fertilization should be reasonable: Milan flowers have strong flowering and blossom times, so they must replenish nutrients in time. Every time Milan blossoms, we should pay close attention to replenishing nutrients. Lack of fertilizer is the main reason why Milan flowers only grow leaves but do not blossom or fall leaves and buds. Therefore, when the temperature rises, the Milan flowers should be moved to outdoor conservation. After a week, they should loosen the soil, apply some thin nitrogen fertilizer, use 10% to 20% rotten cake fertilizer water or human feces and urine, and then apply liquid fertilizer every 10 days or so to promote the growth of its branches and leaves. Since June, the Milan flower has entered the period of vigorous growth and flowering until the middle of October. If a thicker fertilizer based on phosphate fertilizer is applied every 15 days or so, or 0.3% potassium dihydrogen phosphate solution is sprayed every 15 to 20 days, the flower will bloom more luxuriantly. Special attention is paid to the fact that the florescence must be dominated by phosphate fertilizer, otherwise there will be only long leaves but no flowering. In the flowering period from June to October, if there is insufficient fertilization, not only the number of blossoms will decrease and the flowers will not smell good, but the buds that have already appeared will wither and cannot open.

4. Watering should be timely and appropriate: the number of watering times of Milan flowers should be determined according to the size of the plant, the change of climate and the place of placement. Increase the application of phosphorus and potassium fertilizer before flowering, and there is often sunlight scattering, the water is moderate, its flowering aroma will be strong. Summer is the peak growing season of Milan flowers, and the water demand is also increasing, generally watering once a day. In the hot and sunny weather, water can be watered once every morning and evening. If there is a lack of water, it will make the leaves yellow or even fall off. In case of showers, pour water into the side basin after the rain to prevent rotting roots.

How to raise white orchids? Pot culture methods and matters needing attention of white orchids

White orchids have a strong aroma and a long flowering period, blooming from June to October. Put one in the pocket, or a few in the living room, the aroma can last for more than ten days, even after drying and shrinking scorched yellow, using it to make tea is still very fragrant. Family cultivation of white orchids, to have a larger balcony and courtyard, and to have sufficient Yang Guan, because it is Xiyang flowers and trees, otherwise it is not good.

How to raise white orchids?

1. White orchids are neither drought-tolerant nor wet-tolerant. The weather in summer and autumn is hot, evaporation is fast, water demand is large, and watering should be timely. It is advisable to keep the soil slightly wet. Its roots are thick and fleshy, and it is most afraid of waterlogging, so the basin soil should use leached humus soil. Do not be caught in the rain in the mildew and rainy season, if the pot soil is wet for a long time, it will rot, causing the leaves to yellowing and fall off and die, which is difficult to save. This should pay special attention to the white orchid that is dormant in the room, because of the large magnolia planted in the cylinder, the wall of the cylinder is impervious to glaze, and the plant evaporation is small at this time, the topsoil in the jar is easy to dry, and the heart soil is difficult to dry. If you only see the white on the table, it will make the basin soil often wet and die. People plant white orchids to death, which often leads to this malpractice. Therefore, the basin soil is easy to be a little dry in winter, and the heart of the tank is dry, so you must not water it.

2. White orchids like fertilizer, but avoid concentrated fertilizer. In addition to pouring enough basic fertilizer when changing pots every 2-3 years, generally, after flowering, water with rotten bean cake or fishy water is watered every 7-10 days. It is necessary to master the principles of sparse application, regular application, evening and so on. Stop fattening after cool autumn.

3. White orchids are afraid of cold and like the sun. They should have more than 10 hours of sunshine every day. Even if dormant in winter, it can not be shaded for a long time, otherwise it will affect flowering in the coming year. It is more afraid of the cold than jasmine. It enters the room in early November and overwinters, and can not leave the room for maintenance until the middle of April of the following year.

4. White orchids are not resistant to pollution. Besides cannot plant in the factory area, the family maintenance also should not put in the kitchen overwintering, avoids the lampblack pollution.

Matters needing attention in potted white orchid culture

1. The fleshy root of the white orchid is most afraid of stagnant water. The potted soil needs to be acid soil with good drainage, and the basin bottom should be covered with 3-4 cm thick granular furnace ash or broken tiles to make water layer.

2. the sun is strong in midsummer, so it should be properly shaded around noon, or moved to the shade from June to August. Liquid fertilizer should be applied every 1-2 weeks in the peak growing season (May-September), and the basin soil should be kept moist regularly. In summer, it is also necessary to spray and wash the leaves and sprinkle water to the ground to make the environment moist.

3. It should be kept indoors in winter, the room temperature should be kept at about 12 ℃ during the day, and the minimum at night should not be less than 5 ℃. When you first enter the room, you should not water too little. Before and after the Winter Solstice, the white orchid entered the dormant period, need to control watering, stop fertilization and pay attention to proper ventilation.

4. If yellow leaves are found in the cultivation process, 0.2% ferrous sulfur solution should be sprayed 2-3 times in time, which can make the leaves gradually change from yellow to green. It is forbidden to apply thick fertilizer. Sufficient basal fertilizer should be applied when changing pots every 2-3 years. Thin and rotten bean cake water and fishy water should be applied every 10 days after flowering, and fertilizer should be stopped after cool autumn. Need to light more than 10 hours a day, in the winter dormancy period should also be placed in the indoor weak light or scattered light, to avoid lampblack pollution. Never move the white orchid into the kitchen during the winter. There are two kinds of yellow leaves in white orchids-chlorosis caused by iron deficiency and root rot caused by excessive water.

① chlorosis: the main basin soil is alkaline.

② root rot disease: the root system is black and rotten, and the leaves are yellow and shedding, resulting in the death of the whole plant. Therefore, it is usually necessary to wait until the basin soil surface is white before watering, and often loosen the soil.

5. Maintenance and management in spring. When shedding flowers, poke short from about 3-4 stem nodes under the residual flowers, and remove some old stems and over-dense stem nodes to facilitate ventilation and adapt to the family balcony environment. After flowering in March, there is a short period of dormancy, fertilizer and water should be stopped.

6. In summer, crab melon orchid can grow slowly at 15 ℃, and grow faster when the air is moist at about 25 ℃. When the temperature exceeds 30 ℃, even if it is in shady environment.

7. during the maintenance of autumn and winter, the temperature is still high in early autumn, foliar water and environmental sprinkling should continue. From September, crab melon orchid gradually returned to growth, and sunshine could be seen in the morning and evening with the decrease of temperature in mid-late September. In the middle and last ten days of October, all-day sunshine should be given to promote flower bud differentiation and more pregnant buds. To the first and middle of November, the temperature turned cold, crab melon orchid to enter the house for the winter, the room should also be sunny place. However, direct sunlight should be avoided in the flowering period to prolong the flowering period, the watering in autumn should be appropriate, and the basin soil should remain moist, not dry, not waterlogged, too dry, too wet, sudden drop in temperature or excessive temperature difference between day and night, which will cause falling flowers and buds.

8. Due to the low temperature in winter, the evaporation of crab melon orchid is also reduced. Attention should be paid to watering. Rotten roots often die because of too much watering in winter. Autumn and winter is the period when crab melon orchid blossoms. Every 7-10 days, topdressing with more phosphorus should be applied and fertilizer should be stopped during flowering. The temperature is changeable in winter, so it is necessary to do a good job of heat preservation and ventilation. It is necessary to prevent freezing when the room temperature drops to 5 ℃. It is common to culture crab melon orchid in some families in the south of the Yangtze River. Although it is full of buds, it is difficult to bloom when the room temperature is not kept at about 15 ℃.

White orchids can bask in the sun

Magnolia flowers like warmth, love the sun, need enough sunshine throughout the year, winter dormancy should shine a little sunshine when keeping warm, summer and autumn growth and flowering period, there should be enough light. Sufficient light, good growth, more flowering and fragrant flowers; lack of light, thin growth of branches and leaves, few flowering and poor fragrance. In addition, the basin soil should be watered when it is dry, especially in high temperatures in summer and autumn, and the basin soil should be watered thoroughly when it is dry. If the basin soil is too dry for a long time, it will cause leaf yellow shedding and affect growth. However, it should be noted that the drainage of the basin soil must be unobstructed to prevent stagnant water, otherwise, the roots and leaves will rot, and the method of fertilization, like Milan and jasmine, can be adopted to apply "thin fertilizer frequently".

White orchids shed a large number of leaves during the winter

White orchids often encounter a large number of fallen leaves when they spend the winter indoors or in the greenhouse, especially when the greenhouse is hot and cold. The reason: the first basin of soil is not dry and wet, sometimes dry and sometimes wet, fleshy roots can not bear, causing leaf water backflow, there are fallen leaves. Second, the same situation will happen when the room temperature rises, the environment is muggy and there is no timely ventilation. There is another reason, because of the cold.

In order to prevent a large number of white orchids from falling leaves during the winter, the amount of water should not be too much after the basin soil is dry. Keep room temperature between 5-10 ℃, not too high or too low. It is necessary to increase environmental humidity and indoor ventilation to keep the air flowing. In this way, the phenomenon of falling leaves of white orchids can be reduced. In addition, the white orchid after falling leaves, as long as the terminal bud is alive, the leaves will grow again after the spring comes out of the house.

How do white orchids survive the winter

Potted white orchids enter the room for the winter and often lose their leaves. At first, brown dots and dry tips appear on the leaves, then fall off, and then grow new leaves again. The main reason is that the room temperature is too high. When the temperature exceeds 15 ℃, the relatively dormant orchids sprout again. After the new buds occur, the old leaves will fall off because of the physiological phenomenon of metabolism in the new town. However, these new leaves and shoots, due to indoor light and temperature and other conditions are not enough, new leaves are weak, very easy to yellow.

Home potted Magnolia, after "the Autumn Equinox" into the room, the room temperature should not be too high, about 10 ℃ is more suitable. Pay attention to indoor ventilation, but do not directly open windows to blow cold air, potted flowers should be placed in places with sufficient light, controlled watering, and fertilization is prohibited.

After "the Beginning of Winter", if the temperature drops, you can make a plastic shed to cover the brandy, which can not only ensure a relatively stable temperature, but also ensure a certain temperature and prevent smoke and dust pollution. Note that the shed should have vents to avoid excessive temperature, enough to make the mold develop. Try to cool down when the room temperature is too high in spring.

Before and after the Qingming Festival, you can move outside at noon on a clear and windless day, put it in the leeward and sunny place, and spray water to the page. At night or in case of cold spell, it should be moved back indoors, so that when the temperature is stable above 10 ℃, it can be maintained normally outside.

How to raise Milan flowers, breeding methods and matters needing attention of Milan flowers

How to raise Milan flowers? What are the breeding methods and matters needing attention of Milan flowers? Today we are going to talk about the cultivation techniques of Milan flowers. Milan flower alias tree orchid, four seasons Milan, is an evergreen shrub or small tree, its branchlets are often covered with star-shaped rust-colored scales. Milan is a favorite flower plant, and its flowers will smell good when they are in bloom.

Culture methods of Milan flower

Milan likes warm, humid and sunny environment, not cold-resistant, slightly shade-tolerant, the soil is the best in loose and fertile slightly acidic soil, and the winter temperature can not be lower than 10 degrees, growing in sparse forests or shrubs at low elevations all the year round.

Temperature: the temperature suitable for Milan to grow is 20 to 25 degrees, which is usually taken as the standard, and when the flowering time comes, if the temperature is kept at about 30 degrees, the flowers will have a strong fragrance.

Fertilization: Milan prefers fertilizers, but it is necessary to apply more liquid fertilizers that contain more phosphorus, and it is best to use crushed bones, fish bones, chicken bones and other fermented alum fertilizer, often supplemented with chemical fertilizers containing more phosphorus or fermented rice water.

Potted soil: pottery pots are generally used in aquaculture Milan, while the soil can choose loose, drained and well-ventilated soil, such as culture soil dominated by rotten leaf soil. If you change the basin, you can do it once a year or two, and you don't need to pay too much attention to the basin soil at other times.

Matters needing attention of Milan flower

Milan blossoms more often in a year, so after each blossom, we should fertilize 2 or 3 fully mature dilute liquid fertilizer in time, so that it can blossom continuously and have a strong aroma. Potted Milan seedlings pay attention to shade, avoid strong light exposure, wait for seedlings to grow new leaves, fertilize once every 2 weeks, but the amount of water must be controlled, should not be too wet. In addition to the midsummer noon shade, there should be more sunshine, so that Milan not only blossoms more times, but also has a rich fragrance.

The above are the breeding methods and precautions of Milan flower, in fact, Milan flower can also be used as an edible flower, can extract essence, such as Milan scented tea. In addition, Milan potted plants can be displayed in the living room, study and porch, fresh and elegant, comfortable. Milan is also an excellent scenic tree in the southern courtyard.
