Cultivation methods and matters needing attention of rice orchid

Milan, an evergreen shrub or small tree of Meliaceae, is a lobular variety of Milan. Milan orchid originated in South Asia, and then widely planted in tropical regions of the world. Let's take a look at its cultivation method.

Cultivation methods and matters needing attention of rice orchid

1, Sunshine Milan should be placed in sunny places all year round. If orchids are placed in a garden or balcony with sufficient light and good ventilation, and the daily light is more than 8 hours to 12 hours, the leaves of the plants will be dark green, the branches will be thick, the flowers will bloom more times, the color will be bright yellow and the fragrance will be rich. If orchids are placed in an environment with insufficient sunshine and shade, the branches and leaves of the plants will be slender, the number of flowers will decrease, and the fragrance will be light.

2, watering orchids like to be wet, watering should be based on the dry and wet conditions of the climate, to keep the basin soil moist, not watering too much for a long time. Too dry is bad for Milan's growth, and the leaves will wither. Maintaining high air humidity is beneficial to Milan's growth. In the drought and vigorous growth period, it is best to spray water on the leaves 1 ~ 2 times a day.

3, temperature Milan likes warmth, the higher the temperature, the more fragrant the flowers it blooms. Generally speaking, the temperature is above 30℃, and the flowers will be very fragrant when there is plenty of sunshine. On the other hand, in an environment below 30℃, if it is in a shady place with insufficient light, flowers will not smell as fragrant as when the temperature is high. The suitable temperature for planting Michelia is between 20 ~ 35℃, and it can bloom 5 times at 6 ~ 10.

4, fertilization, orchids bloom vigorously, flowering times are many, and nutrients must be supplemented in time. Every time orchids bloom, they should pay close attention to supplementing nutrition. Lack of fertilizer is the main reason why orchids only grow leaves and do not bloom or fall. Therefore, when the temperature rises, orchids should be moved outdoors for maintenance. After a week, they should loosen the soil, apply some dilute nitrogen fertilizer, fertilize water or human feces with 10% to 20% decomposed cakes, and then apply liquid fertilizer every 10 day to promote the growth of their branches and leaves. From June, orchids entered the vigorous growth period and flowering period, until the middle of 10. It is necessary to apply concentrated fertilizer mainly containing phosphate fertilizer every 15 days, or spray 0.3% potassium dihydrogen phosphate solution every 15 to 20 days, so that the flowers will flourish more. It is particularly important to note that the flowering period must be dominated by phosphate fertilizer, otherwise it will only grow leaves and not bloom. During the flowering period from June to 10, if fertilization is insufficient, not only will the flowering times be reduced, but also the flowers will not be fragrant, and the buds that have already appeared will wither and fail to bloom.

5. Pruning Michelia should start with seedlings and leave a section of trunk with a height of 15cm to 20cm. Don't let the main branches grow out of the soil, but prune them above the trunk with a height of 15cm to make the plants plump. The lower branches of perennial plants often age and die. Therefore, it is advisable to cut it every other year in high temperature season, so as to promote the germination of adventitious buds at the lower part of the main branch and grow new lateral branches, so that the tree can maintain a symmetrical posture, the tree is vigorous and the leaves are lush. Orchids are in full bloom from May to September, or all the year round, with fragrant flowers. It is a good plant for home decoration. Imagine a breeze blowing and the house is full of fragrance. What a pleasant thing it is. This is the end of Michelia's breeding method. Go and choose a pot for your family if you like.

Matters needing attention in orchid cultivation.

As long as Milan gives it a proper temperature, it will be full of strange fragrance, and flowers are the most fragrant at this time of summer, and the most suitable temperature for flowering is 30 degrees Celsius. Pay attention to control the temperature at about 25℃ when breeding, so that beautiful and fragrant flowers can bloom normally. Smiling needs sunshine all year round, and the sunshine is preferably 12 hours, so it is best to put it on the balcony or plant it in the yard, so as to ensure the green, bright, fragrant and beautiful leaves. Rice orchids will wither if they can't replenish fertilizer in time and reasonably. Because flowering many times a year will lead to insufficient nutrients, if there is a lack of fertilizer, then it will not bloom, or it will fall before flowering. Therefore, it is necessary to fertilize in time after flowering to prepare for the next flowering. The growth period can be slightly thicker, and the flowering period can be appropriately extended.

Reasonable watering is necessary for its growth. Without water, it can't grow, and if there is too much water, it will rot the roots and yellow leaves. So it is recommended to do it twice a day.

What should I do if the leaves of m blue flowers fall off?

Many people have a lot of problems when cultivating Milan leaves, but they can't find out where the problems are. In fact, this is caused by improper management.

1. If you water it too much or too little, the leaves will fall off. Because there is too much water, the roots will rot, and the leaves will dry up and fall off easily if they are short of water. Flowers with less water directly lead to insufficient water in the leaves, and then they will die directly. You can make a record and water Milan every day. Carry out the principle of doing nothing and watering. Moreover, the sunshine time in Milan will be extended, and the sun will be fierce at noon in summer. You can avoid the shade properly and water the leaves slightly. If the leaves of the rainbow fall off after watering, Milan can transplant them, put them in another pot and then water and fertilize them.

2. If insect pests occur, they will also cause smiling leaves, usually white powdery mildew and scale insects. Therefore, we can properly use pesticides such as limewater to kill insects, and then properly fertilize, water and bask in the sun, and we can recover.

Are orchids poisonous?

Milan orchids are nontoxic. It is not only non-toxic, but also an important component of Chinese medicine in many parts. But it is not recommended to keep it indoors for a long time. Because Michelia is a sunny plant, if there is not enough light and ventilation, the possibility of air flowering will be very small. If there is no light for a long time, pests will gradually increase, leading to the failure of flower growth. But it is good to put it indoors in the short term. Milan orchid can eliminate trichloroethylene, formaldehyde and other harmful gases produced by new house decoration or house itself, and is an environmental guardian.

How to prune orchids?

Milan's first routine pruning is usually in the spring when it is ready to grow and sprout, minus some branches withered or damaged by diseases and insect pests in winter. And dense branches that are too dense to weaken photosynthesis.

During the growth process, seedlings can be pruned to achieve uniform growth conditions. Generally, the trunk of about 20cm can be kept, and the above bifurcation needs pruning. For perennial Milan, the upper branches can be cut off appropriately to ensure the development of lateral buds.

After plants grow, many lateral buds or terminal buds are different during the growth process. It is suggested that they can be pruned appropriately to ensure orderly growth. But in bud stage, branches and leaves can't be reduced, so shade should be used to keep out the sun.

The propagation methods of Michelia are mainly layering propagation and cutting propagation.

High altitude layering method is often used for layering propagation, and the layering time is better in rainy season.

One-year-old lignified branches were selected and peeled at the base of 20 cm, and the peeling width was about 1 cm. Two or three branchlets can be left on the upper part, and all the lower side branches can be cut off. Then apply moss or peat on the girdling part, and pay attention to the disinfection of moss and peat before use. After the package is wrapped, tie it up and down with a film. Don't leak at the lower part, and tie the upper part a little loosely. Then sprinkle water on the bag in time to keep it moist, wait for 2~3 months to take root, and then cut off the mother plant for planting.

Cutting propagation is mainly carried out in June-August. It can be used as a cutting to cut off the robust wooden branches of the year, which are about 65,438+00 cm long. Leave 2-3 leaflets at the spire, cut off the lower leaves, insert them into the seedbed with peat or sand and perlite as the substrate for about 4 cm, then pour water, seal the spout with plastic film, and keep warm and moist. It takes about 2 months to keep the indoor temperature at about 28 degrees Celsius and the humidity at about 95%, and to keep the transplanting bed moist. If the cuttings are soaked in 500ppm tea acetic acid solution for about 20 hours before cutting, they can be cleaned before cutting, which can promote the cuttings to take root early.

Milan winters.

Before and after the first frost, when the temperature drops below 10 degrees Celsius, Milan will live in a room with potted plants. Generally, as long as the indoor temperature is not lower than 5 degrees Celsius in winter, it can be safely wintered. Even if the weather is a little cold and the branches have fallen leaves, after pruning and changing pots in the next spring, strengthening water and fertilizer management and careful maintenance, new leaves will soon be pulled out and bloom again.

In case of extremely cold weather, two layers of plastic bags can be placed on the plant cover to keep warm, and several holes can be punched in the plastic bags to make them breathable. Take off the plastic bag every 1~2 days and let it breathe fully, otherwise the leaves will turn yellow.

The indoor temperature should be kept between 8℃ and 10℃. If the temperature is too high, the top branches are easy to sprout new buds and consume nutrients, and they are easy to wither when they leave the house in spring, which directly affects the growth and flowering of the next year.

During the winter, it is also necessary to avoid the ups and downs of indoor temperature and not to change places frequently.

During the wintering period, the soil in the basin must be kept moist. Too dry will cause the leaves to fall off, too wet will cause the leaves to fall off and rot. You can spray water on the leaves when the air is dry. It is best to spray at noon on a sunny day, and the temperature of the sprayed water should be similar to that of the basin soil. If the leaf surface is polluted, it should be cleaned so that it can breathe normally.

If Milan can't water for a while because of going out and other factors, you can put a shallow pot under Milan flowerpot, and the soil in the pot is moist, so that plants can absorb some water from the bottom of the pot.

If dead leaves are found, they should be removed in time to avoid excessive nutrient loss and affect the appearance.

Pay attention to ventilation after entering the room, but don't put it in a ventilated environment to avoid frostbite.

After Tomb-Sweeping Day left the room, the temperature was basically stable at 15 degrees Celsius. Before leaving the room, let it adapt to the outside environment. You can open the window and let Milan adapt to the outside air gradually. After a while, go out again.

Pest control.

The main diseases in Milan are stem rot, anthracnose and Milan yellow disease. Pests mainly include white moth wax cicada, aphid, red spider, scale insect and so on.

Stem Rot If stem rot occurs in plants, the branches should be coated with 0.5%~ 2% Bordeaux solution or 70% thiophanate-methyl 800 times solution in time at the initial stage of the disease. Anthrax Anthrax is the main infectious disease in Milan, and it often breaks out from June to 65438+ 10. Infected leaves will start from the tip and edge of the leaves and gradually turn brown. If infected with this pathogen, petioles and stems will gradually turn brown.

To prevent and control this pathogen, it is necessary to remove the diseased body in time after finding the diseased branches and leaves, cut off the source of infection, and then improve the ventilation conditions. It can also be sprayed with 1000~ 1200 times potassium permanganate aqueous solution.

Red spider and aphid can be sprayed with 40% dimethoate 1000~ 1500 times water solution or 1200 times dichlorvos water solution if their plants are harmed by the above pests.

Cultivation methods and matters needing attention of rice orchid;

1, lighting

Potted seedlings in Milan need shade and maintenance, and grow slowly under strong light. After the seedlings take root, they can be maintained in sufficient sunlight. However, it should be noted that potted plants are different from planting directly on the land, and the soil of potted plants is limited. In summer, we'd better cultivate in a semi-shady place, otherwise it will easily lead to excessive evaporation of water and yellowing of leaves. In spring, autumn and winter, you can fully contact the sun, which can better help its growth.

water

Milan doesn't like too wet soil, and its growth rate will be hindered in long-term wet soil. Generally speaking, watering according to the principle of seeing dry and seeing wet will not cause water damage. As long as the soil is not dry for too long, you can water it earlier, especially in summer, because the water evaporates quickly in summer, and the frequency of watering in winter needs to be extended appropriately. Generally speaking, it is enough to water once every ten days and a half months in winter. Too much watering will cause the leaves in Milan to turn yellow and fall off, and too much watering will easily lead to the phenomenon of falling flowers when flowering. Too little watering can also lead to the problem of dry leaves and withered buds before flowering. In summer, when the air is dry or evaporation is high, we can spray Milan leaves in the morning and evening to humidify it.

Step 3 apply fertilizer

After the transplanted seedlings take root, we can apply fertilizer once a week according to the principle of thin fertilizer and diligent application. Common fertilizers are compound fertilizer, phosphate fertilizer, potash fertilizer and ferrous sulfate. If you don't know when and what fertilizer to use, you can use compound fertilizer. Don't fertilize when applying fertilizer, otherwise burning roots with fertilizer will easily lead to plant death. Of course, if we have a pot of fertile soil, we can reduce the trouble of long-term fertilization!

4. Land

Milan likes to grow in acidic soil. We can choose humus soil, garden soil, sandy loam soil, peat soil, pond mud and so on. Sort by merit. We can also use the mixed soil of the above soil, or add some coconut bran and coarse river sand to help enhance the looseness, drainage and air permeability of the soil. This kind of soil can make Milan peanuts have long-term green leaves and many flowers at flowering stage.

5. Temperature

The optimum growth temperature of Michelia is 65438 05 ~ 25℃. If the temperature is higher than 35℃ in summer, the leaves will become soft, and the old leaves will fall off prematurely in the long-term high temperature environment. Therefore, it is recommended that you cultivate in a place with sufficient scattered light in summer. It is suggested that the temperature should not be lower than 10℃ for safe wintering in winter. If it is below 5℃ for a long time, the leaves will turn yellow and fall off. In order to make it have better viewing effect, let's try to control the temperature!
