Culture methods and matters needing attention of flower plant Cymbidium

Tiger ear orchid, also known as tiger ear, tiger tail orchid, cattle tongue orchid, etc., originated in southern Africa, is a perennial evergreen herb belonging to the genus tennis flower of Amaryllidaceae. Its leaves are evergreen all the year round. Its posture is beautiful. When it blooms, yellow anthers are born at the top of white flowers. It is bright and eye-catching. It is suitable for indoor potted plants to appreciate. Let's take a look at the cultivation methods and precautions of tiger ear orchid together.

Growth Habits of Tiger's Ear Orchid

Tiger ear orchid origin African tropics, our country introduction cultivation. Enjoy sunny, warm, humid and well-ventilated environments. It is drought-tolerant, not cold-resistant, growth temperature of 15~25℃, requiring good drainage of slightly acidic loam. Cultivation substrate can be peat, rotten leaf soil and river sand mixed thoroughly. During the growing season, apply decomposed cake fertilizer once a month and supplement phosphorus fertilizer appropriately. After winter dormancy, pots can be changed and plants can be divided again. In cold areas to move into greenhouse maintenance, ensure that the minimum temperature is 5℃, otherwise vulnerable to freezing damage.

Breeding method of tiger ear orchid

1. Sowing and reproduction: The seeds of Tiger's ear orchid mature more than 2 months after flowering and can be directly potted. They germinate 15 days after sowing, and the seedlings take 4 to 5 years to bloom.

2, plant propagation: tiger ear orchid bulb development is slow, generally 2 to 3 years plant division once, in the spring when the pot out of the mother plant, split apart can be planted.

Cultivation method of tiger ear orchid

1. Soil: Tiger's ear orchid is suitable for growing in loose, fertile and slightly acidic sandy loam with good drainage. It can be mixed with peat, moldy soil and river sand. It is fertilized once every ten days during the growth period.

2. Watering: Tiger ear orchid should be watered after the topsoil is dry. Avoid rain and accumulated water, which will cause the bulb to rot. Summer and autumn basin soil is too dry, then affect leaf growth. Winter has a short-term semi-dormant state, should reduce watering.

3, light: Tiger ear orchid needs a better light environment, summer to shade, other seasons to strengthen the light, too much shade not only thin leaves, but also affect flowering and whole plant posture.

4. Temperature: The suitable temperature for the growth of Tiger's ear orchid is 10~12℃ at night and 16~21℃ during the day. Summer should be semi-shade, flowering should be cool, late autumn bulb dormancy winter, not lower than 5℃, and keep the soil dry.

Notes on Tiger Ears

1, tiger ear orchid in the rainy season to pay special attention, can not let rain, let alone let basin soil water, should be placed in shelter.

2. Tiger's ear orchid usually applies 15% cake fertilizer water once every half month, and applies compound fertilizer twice before flowering.

3. Insufficient light or excessive humidity in the pot will cause excessive growth of branches and leaves, resulting in soft drooping of leaves and reduced ornamental value.

4, tiger ear orchid is not too cold, early winter should be moved indoors, placed in the sun, as long as the temperature is not lower than 0℃ can winter.

5. Biological characteristics

Tissue culture is often used in flower seedling production because of its advantages such as high reproduction coefficient, fast speed and virus-free strains. Tiger ear orchid is a bulb plant of tennis flower genus of Amaryllidaceae, also known as white flower tiger ear orchid, white flower tennis flower, white flower brush flower, native to southern Africa, tiger ear orchid can be observed flowers and considerable leaves, early winter flowering in Shanghai area, flowering period can be as long as 2 months, its flowers, leaves delicate, beautiful and generous, evergreen plants, very suitable for indoor potted viewing. Common ramets or sowing propagation, but Shanghai area can not produce seeds, propagation is very slow. A new possible way for rapid propagation was provided. The young leaves germinated in spring from the vigorous growing potted plants were washed with tap water, rinsed with 75% alcohol for 30 minutes on a super clean bench, rinsed with sterile water for 2 times, washed with saturated bleaching powder solution for 20 minutes, rinsed with sterile water for 3 - 4 times, dried with sterile filter paper, cut into 0. 5 pieces of explant, Inoculate in induction medium of +0.65% agar +3% sucrose +6% and concentration. Inoculate 40 pieces per treatment and repeat 3 times. 6 The sum and combination are as follows: '1:6 - 0.5/(unit the same below)+0.2;-2: 6 - 0.5+1.0;-3: 6 - 0.5+2.0;-4: 6 - 1.0+1.0;-5: 6 - 2.0+1.0;-6: 6 - 3.0+1.0;-7;6 - 2.0+0.1;1-8:6 - 3.0+0.1.1.3 Plantlets multiplication The explant pieces with adventitious buds were cut into small pieces and inoculated on the medium of +0.65% agar +3% sucrose +6-and different concentration + different concentration, 20 pieces were inoculated on each medium, repeated 3 times. 6. The ratio and concentration of 1:6 - 2.0+0. 1 2:6 - 2.0+0.1+0.2%; 1 3:6 - 0.5+2.0.

Count the multiplication times of adventitious buds (multiplication times = total buds/inoculated buds) and observe the growth of adventitious buds. 1.4 RootingUnder aseptic condition, rootless plantlets of more than 2.5 years, which were basically the same in growth, were inoculated in 1/2+0.65% agar +1.5% sucrose + different concentrations or + different concentrations of medium, 66 plantlets were inoculated in each medium, repeated 3 times. After 20 years of culture, the rooting rate of plantlets in each medium was counted, and after 40 years, the growth indexes of roots (root number, root length, root-shoot ratio) were determined. or the concentration and concentration combination are as follows: 1: 0.2; 1:2: 0.2+0.2%; 1:3: 0.2; 1:4: 0.2+ 0.2%; 1.5 After the transplanted seedlings grow vigorous roots, open the bottle and train the seedlings at room temperature, and directly transplant them into the flowerpot of 1/3 peat +2/3 sandy loam soil; or after the seedlings are trained at room temperature, first transplant them into (peat):(pearlite):(vermiculite)=4:2:1 of peat +2/3 of sandy loam soil.

2.1 Induction of adventitious buds The explants were inoculated on medium 1, 2, 3, 4, 5, 6, 7 and 8 respectively, and the explants were obviously thickened and expanded about 15 days later. After 7 days of culture, a few calli appeared at the incision of explants. Adventitious buds were formed on explants cultured on medium-7 and-8. A few calli appeared on medium 1, 1, 1, 3, 4, 5, 6 continued to grow and formed obviously enlarged calli around explants. Calli on medium 30, 1, 2, 3 differentiated into a few adventitious buds, while calli on medium 4, 5, 6 continued to grow and browned gradually. Adventitious buds rarely differentiated and adventitious roots appeared in some calli. The adventitious bud induction rate of explants in the above medium was counted [adventitious bud induction rate = number of explants/(number of inoculated explants-number of contaminated explants)], and the induction of adventitious buds was observed.

++++ 10 +,+++()? From Table 1, it can be seen that there is a significant difference in the induction rate of adventitious buds between different combinations of 6 - 7. Medium-8 and-7 significantly increase the induction rate of adventitious buds, reaching 100% and 95%, but the growth potential of adventitious buds in the former is worse than that in the latter.

The results showed that medium 1-7, i.e. 6 - 1 and concentration of 2.0 and 0.1 respectively, was most beneficial to the induction of adventitious buds. Adventitious buds in 1 medium grew worse than 1 medium, yellow-green, slower growth; 1 medium significantly reduced the multiplication multiple of adventitious buds, while callus was easy to differentiate roots and continue culture for a period of time.

How to raise tiger ear orchid cultivation methods and precautions

Tiger ear orchid is a common herb, the former origin in Africa, later introduced by our country planting, now the distribution is very extensive. Because of its high ornamental value, it attracts many people's breeding. However, before breeding, it must be a matter of concern to understand its breeding technology.

How to raise tiger ears

1. The potting soil is a mixture of decayed leaf soil, coarse sand and peat. Plant growth period to fertilizer, every ten days to apply once, fertilizer amount should not be too thick and excessive. Summer and autumn when the pot soil is dry to timely watering, watering to irrigate thoroughly. In winter, tiger-eared orchids will enter a semi-dormant state for a short period of time. At this time, water less and place them indoors in the sun.

2. Shading should be carried out in summer when the light is strong, and light and water and fertilizer management should be strengthened in autumn, so as to promote the good development of inflorescences and facilitate the beauty of the whole plant posture. The suitable temperature for the growth period is 18~24℃, and the temperature should be kept at 13~15℃ in winter.

Method for cultivating tiger ear orchid

1. Soil. Tiger ears prefer slightly acidic soils. And the permeability of the soil is good, so you can choose slightly acidic sandy soil, that is, a mixture of rotting soil, peat and coarse sand soil. This is conducive to soil air mobility and moisture permeability, conducive to the growth of tiger ears.

2. Temperature. The growth temperature of tiger ear orchid is suitable for 16-21℃ during the day and 10-12℃ at night. Because tiger ear orchid cold tolerance is very poor, so winter temperature should not be lower than 5℃, should be placed indoors or greenhouse in winter.

3. Light. Tiger ear orchid requirements like semi-shady environment, especially dead summer time to put tiger ear orchid placed in a semi-shady environment, not in the sun exposure, but also can not be completely dark corner, which is not conducive to the growth of tiger ear orchid.

4, moisture: in the growth period of tiger ear orchid, to keep the pot soil moist, to be slightly dry, to avoid rain, pot soil can not accumulate water, otherwise it will cause bulb rot. Bulb rot disease is caused by a variety of fungi and a small number of bacteria infection caused by flowers and crop bulbs rot a disease. This can cause tender stems to fail to sprout or leaves to stagnate, turn yellow to red or green, and eventually wither or die.

5. Fertilization: During the growth period, nitrogen, phosphorus and potassium compound fertilizer should be applied once every half month. Promote the growth of tiger ear orchid, reduce pests and diseases.

Notes on Tiger Ears

1. Tiger's ear orchid likes sunshine, warm and well-ventilated growth environment, and is not resistant to cold. When winter is cold, tiger's ear orchid is most prone to freezing damage. Its leaves will rot due to freezing damage, wither, and then fall. The stem of the plant will also become dry.

2, so in the cold, put it in the balcony where there is light, give enough sunlight; when the weather is cold, you can wrap the plant with plastic film, and take anti-freezing measures. Pay attention to ventilation, but don't let the plants face the tuyere.

Leaf spot disease of Cymbidium sativum and its control method

1. The most common disease in the disease cycle of Tiger's Ear Orchid is leaf spot disease. Tiger's ear orchid with leaf spot disease will seriously affect the leaves of plants, causing them to gradually turn yellow and eventually lead to withering. Sometimes it can lead to abnormal development of leaves, or no flowering. Reduce the normal growth of plants and plant aesthetics.

2, cause When tiger ear orchid has this condition, it indicates that the plant growth environment is not suitable. It may be caused by improper fertilizer and moisture.

3, we can fertilize the plants on time and in quantity, the specific time is once every three months Tiger ear orchid demand for light is very large, in addition to summer, other seasons need to strengthen the light, if the sun is insufficient, can lead to thin leaves, and even threaten the health of plants.

Tiger ear orchid in the cultivation of the first time to choose a good soil, and then light, temperature regulation. After this, we need to strengthen the management of water and fertilizer. Too much or too little will be unfavorable to its growth. The most common leaf spot disease is leaf spot disease when tiger ear orchid is cultured, so it is also very important to prevent leaf spot disease.
