Is Cymbidium grandiflora an annual plant, and the lifespan of Cymbidium grandiflora

No. 1. Light.

Orchid is not a plant that likes strong light, especially in summer, the leaves will have various problems, if not solved in time, it will slowly wither, then in the summer to breed it, it is best to put it in a scattered place to breed, block most of the sunlight, in order to breed better, but now it is autumn, orchids should be easy to grow and then overwinter, at this time it can not hinder it from contacting the light, and when the temperature is low in winter, it is more necessary to put it in a place with good light and high temperature.

2. Watering. The water requirement of the growing period is relatively high, at this time it is necessary to replenish enough water in time, and the water evaporates faster than usual when the temperature increases in summer, in order to avoid water shortage, it is necessary to increase the amount of water in the appropriate amount, on the contrary, the water intake should be reduced in winter, and when watering in winter, the water temperature should be the same as that indoors, so as not to frostbite the plants after watering at low water temperature.

3. Precautions.

In the summer when the temperature is high, we should add a lot of water, but we should also pay attention to not water rotten roots, so we should pay attention to the watering, put it in a ventilated place so as to ensure that there will be no waterlogging, in addition to the plant in the growing season also need to be fertilized, but too much fertilization is easy to burn the roots, but also pay attention to the appropriate amount of the best.

Orchid grandiflora is a general term for the varieties of orchids that have been cultivated through artificial hybridization and have bright colors and huge flowers. There are about 48 species of orchids, and there are nearly 20 native species used as hybrid parents, mainly epiphytes with large flowers and a small number of terrestrial species.

Cymbidium grandiflora is an artificial hybrid of the genus Orchid. Since 1889, when the first large-flowered orchid variety was bred in the United Kingdom, in the 40s of the 20th century, a large number of interspecific and intervarietal hybrids were also bred in Europe and the United States. So far, there have been 20,000 cultivars of Cymbidium grandiflora, which are very popular in the domestic and foreign markets, and have become a huge variety group of orchids.

1. Cymbidium macroflora (scientific name: cymbidium hybridum sleeve) is an evergreen perennial epiphytic herb of the genus Orchidaceae, even in the north, it is reliable for false bulbs to overwinter and reproduce new plants, and the life span of Cymbidium macroflora is about 10-30 years due to the influence of lack of potato traces under cultivation conditions.

2. The tissue culture seedlings of Cymbidium grandiflora should go through years of vegetative growth before they can enter the reproductive hand hunger growth, carry out flower bud differentiation and development, and flower blooming. After the full vegetative growth stage, C. grandiflora enters the reproductive growth stage. The flower buds of Cymbidium grandiflora are formed by the development of side buds, and the side buds that differentiate into flower buds begin to extract flower buds.

The flower buds of Cymbidium grandiflora are mostly formed on the pseudobulbs formed by the annual shoots, which are generally left on the old pseudobulbs in October and November of the previous year. Flower buds generally grow at the base of the pseudobulb 2 4 nodes, and each pseudobulb forms 1 2 flower buds.

The normal flowering period is from October to April of the following year, and it is possible to bloom during this time, and the flowers can bloom for about 20 days. In general maintenance, it can only bloom once a year, and it is not completely impossible to bloom twice, but the possibility is very small, and the growing conditions required for this are high, and many factors are required, so it must be carefully cared for.

1. Sufficient sunlight: It is a plant that likes sunlight very much, and it can accumulate nutrients to promote the second opening of flowers by ensuring sufficient light, but it cannot be placed directly in the sun in summer, and it still needs proper shade.

2. Pruning after flowering: After its flowers wither, the residual flowers must be removed, which can reduce the consumption of nutrients and accumulate nutrients for new flowers, otherwise it will have a greater impact on reflowering.

3. Replenish water: replenishment of water is also a very important factor, the impact on flowering is greater, pay attention to watering during the growth period, can not appear too dry, watering 2-3 times a day in summer, watering once in 3-4 days in other seasons, and maintain good humidity.

4. Apply fertilizer: Fertilize before flowering, and don't forget to supplement after flowering, so as to accumulate enough nutrients for future growth.

Cymbidium grandiflora blooms once a year, the flowering period lasts from October to April of the following year, suitable for growing in a warm winter and cool summer environment, the best growth temperature is between 10-25 degrees, in addition, Cymbidium grandiflora is a perennial evergreen herbaceous plant of the orchid family, leathery leaves are ribbon-like clusters, peduncles grow from pseudocorros, and dozens of flowers can bloom on each peduncle.

Native to India, Thailand, and southern China, it is suitable for growing in a warm winter and cool summer, with an optimal growth temperature between 10 and 25 degrees Celsius, and poor growth below 5 degrees.

Orchid grandiflora is a perennial evergreen herbaceous plant of the orchid family, the cylindrical fleshy roots grow well-developed, generally grayish-white, the leathery leaves are ribbon-like clusters, the color will be affected by light, the peduncle grows from the pseudobulb, and dozens of flowers can bloom on each peduncle, and the color of the flowers is rich and bright.

After the end of the flowering period of the orchid, cut off the residual flowers with sterilized scissors to reduce the consumption of nutrients, except for watering once every 2-3 days in summer, watering once every 7-10 days in other seasons to keep the soil moist, and choose diluted organic fertilizer topdressing to make up for the nutrients consumed during flowering.

Common diseases during the planting of C. grandiflora are gray mold, anthracnose, soft rot and other diseases, suffered from the erosion of red spiders and scale insects, the early stage of infection selects mancozeb, carbendazim and other agents, sprayed once a week, 3 times in a row to prevent and control, can be manually captured when suffering from insects and insects, and can also be sprayed to kill and control.

Its inflorescence is long, the flowers are rich in color, white, yellow, red, etc., and the large-flowered orchid is native to India, Thailand, Vietnam and other regions, and is now cultivated in Henan, Jiangsu, Hubei, Hunan, Zhejiang and other regions in China. When maintaining the large-flowered orchid during the flowering period, it is necessary to cut off the residual flowers of the plant to avoid the loss of excess nutrients.

And to place the large-flowered orchid in a bright place, let it receive no less than 5 hours of light per day, and to control the frequency of watering, you can water every 2-3 weeks, so as not to drop the flower buds. When cultivating Cymbidium grandiflora, it is necessary to use a mixture of humus, perlite and pastoral soil to make soil, and then apply well-rotted organic fertilizer to the soil to improve soil fertility, and spray potassium permanganate solution to the soil for disinfection.

Maintenance of the large-flowered orchid

Many people understand that ventilation is to raise flowers indoors for ventilation, that is, to open the window, in fact, ventilation is to let the air flow, if the indoor air does not flow, even if the window is open, the ventilation is not good. Raising large orchids and orchids has particularly high ventilation requirements, you can add an electric fan on the balcony, and there are friends who raise succulents, directly add a fan or add a ventilation fan.

Then let the air flow, and after watering, the excess water will evaporate and take the excess water away. If the air is not circulated, it is easy to have stagnant roots, of course, if there are outdoor conditions, it is also very good to put it in an outdoor semi-shaded place for maintenance.

10-30 years.

Cymbidium grandiflora is an evergreen perennial epiphytic herb of the genus Orchidaceae, which can reliably overwinter and reproduce new plants even in the north, and the lifespan of Cymbidium grandiflora is about 10-30 years depending on the culture conditions.

Although the ornamental effect of the large-flowered orchid is a kind of orchid, but because the flowers are more expensive, there is no record of edible it until now, and its efficacy and function is to beautify the environment and for people to watch. The potted hand Danchong large-flowered orchid plant purifies the air The large-flowered orchid is also very common in the garden scenic spot, it can absorb and decompose the toxic gases in the air, and can play a role in purifying the air.

The natural flowering period of the orchid is from October to April, and with the development of technology, the flowering period of the orchid can be adjusted at the same time. June to October is the flowering control period, and it is believed that the controlled flowering period is feasible for 20 days before and after, and there is quality assurance. To control the flowering period, it is necessary to control the temperature, and it is best to not exceed 30 degrees in the shed during the day, and ten degrees higher than the outside temperature.

The cultivation method of the large-flowered orchid

1. Temperature, choose a place that is warm in winter and cool in summer, with a growth temperature of 10-25 and a temperature of about 10 at night.

2. Water quality, acidic water, rainwater is the best, high air humidity in the growing period, in general, the large-flowered orchid is afraid of dry and not afraid of wet.

3. Light, shading 50 -60 in midsummer, and more sunlight in autumn, which is conducive to the formation and differentiation of flower buds. In winter rainy and snowy days, increasing auxiliary light is extremely beneficial to flowering.

4. Pest control, black spot disease and wheel spot necrosis disease harm leaves, 70 methyl tobuzin wettable powder can be used.

The seedlings will bloom after a year, the flowering period of the large-flowered orchid is from October to April of the following year, when the plant is in the flowering period, it should be placed in the indoor environment with sufficient light, to provide full sunshine for the large-flowered orchid, to ensure the smooth growth of the flowers, pay attention to the need to control the temperature of the plant growth environment at about 15 degrees.

1. One year

The flowers of the large-flowered orchid will bloom in October every year, and the flowers will gradually wither until about April of the following year, and the flowering period is as long as 6 months, so the large-flowered orchid is very suitable for maintenance at home and adds luster to the interior.

2. Indoor maintenance

When the orchid is in bloom, it should be placed on the window sill or semi-shaded balcony of the indoor sunrise to provide all-weather natural light for the plants.

3. Control the temperature

In winter, you need to use heating equipment to adjust the room temperature to between 15-25 degrees to avoid frost damage to the plant, and pay attention not to place the large-flowered orchid next to the heating outlet, otherwise the buds of the plant will be dehydrated and dry.

4. Replenish water

In winter, when maintaining the large-flowered orchid indoors, it is necessary to water it every 3-5 days to keep the potting soil moist, and at the same time spray water mist twice a day around the large-flowered orchid to avoid leaf wilting, pay attention to the winter watering, you need to place the water indoors for 3 hours, so that the water temperature and room temperature are consistent, in order to prevent frostbite on the root system of the large-flowered orchid.

1. Grow buds several times a year.

Generally speaking, Melan can only germinate once a year. Its germination period is March-April every year. When the temperature rises, many sprouts will grow. After that, it will be difficult to germinate again. However, if it is a newly planted seedling, new shoots may grow after a period of planting.

2. How to promote bud growth.

1.Control the temperature and light: If you want it to germinate smoothly, you need to raise it around 15 in winter and give it some mild sunlift.

Don't put it in too hot a place, otherwise it will sprout early, but the number of new shoots that can grow will be much smaller. 2.Replenish water and fertilizer:

After its sprouts grow, it needs the right amount of water to make its soil slightly moist, which is very beneficial for its sprout growth. In addition, you can apply some low-concentration flower fertilizer to it, which can not only make its new shoots grow better, but also make its growing buds grow faster.
