Sowing and propagation methods of onion orchid and matters needing attention

The scent of onion orchids is not as elegant and fragrant as orchids (details). If there is only one plant, the fragrance is so light that it can not be felt at all, but if it is cultivated in pieces, the breeze blows and the aroma touches the face. Onion orchid can be propagated by sowing, because the growing period of onion orchid is more afraid of heat, so sowing is usually more suitable for autumn sowing in late September.

1. Matrix disinfection: the best way to disinfect the substrate used for sowing is to put it in a pot and stir-fry it, so that any diseases and insects can be scalded to death.

2. Sprouting: soak the seeds in warm hot water (the temperature is about the same as facial wash) for 12 to 24 hours until the seeds absorb water and expand. For common seeds that germinate easily, this work does not have to be done.

3. Sowing: for small seeds that are difficult to pick up with hands or other tools, wet one end of the toothpick with water, stick the seeds one by one on the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding flowerpot into the water. The depth of the water is 1x2x2 / 3 of the height of the flowerpot. Let the water soak up slowly (this method is called "pot immersion"). For larger seeds that can be picked up by hand or other tools, put the seeds directly into the substrate and order them at a distance of 3 × 3 cm. After sowing, the substrate was covered, and the thickness of the cover was 2-3 times that of the seed.

4. Management after sowing: after sowing in autumn, when you encounter cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and moisture. after the seedlings are unearthed, the film should be opened in time and before 9:30 every morning. or let the seedlings receive the sun's light after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

How do onion orchids propagate separately and how to sow and reproduce?

Onion orchid, Latin name: (Zephyranthes candida), perennial herb, bulb ovate, about 2.5cm in diameter, with a conspicuous neck, neck length 2.5-5cm. Leaves narrowly linear, fleshy, bright green, 20-30 cm long and 2-4 mm wide. Native to South America and the western Indian Ocean Islands, it is now planted all over China. It likes plenty of sunshine and is resistant to semi-shade. It is often used as an edge material for flower beds, and it is also suitable for green space cluster planting. It is most suitable to be used as a ground cover plant in the lower half-shade of the forest, or planted beside a courtyard path. It has the effect of reducing swelling and dispersing blood stasis.

Propagation technique of green onion orchid

Ramet time

After the soil was thawed in early spring (February and March).

Ramet method

Take the mother plant out of the flowerpot, shake off the excess potted soil, separate the root system as much as possible, and cut it into two or more plants with a sharp knife, each with a considerable root system. and its leaves are properly trimmed to facilitate survival.

Disinfection in pots

Soak the split plant in 1500 times chlorothalonil solution for five minutes, then take out the cold dry, and then serve. You can also irrigate the root with chlorothalonil immediately after potting. Put the ramet into the basin and irrigate the root or water once. Because its root system is greatly damaged and its water absorption capacity is very weak, it takes about 3-4 weeks to recover new roots. Therefore, it is necessary to control watering within 3-4 weeks after ramet to avoid rotting roots, but the transpiration of its leaves is not affected. In order to maintain the water balance of the leaves, it is necessary to spray the leaf surface 1-3 times a day (spray more at high temperature, less spray at low temperature or no spray at low temperature). Don't fertilize it these days. After the split, but also pay attention to the sun is too strong, it is best to put in the shade to maintain.

Sowing and propagation techniques of onion orchid

Sowing time

Sowing method

The seeds of onion orchids mature about 20 days later and should be harvested in time, because it is the rainy season at that time, and it is very easy for seeds to germinate on the plant. Because it is afraid of heat during the whole growing period, and the optimum temperature for sowing is 15-20 ℃, autumn sowing is often carried out after the middle and last ten days of September.

Matrix disinfection

The best way to disinfect the sowing substrate is to stir-fry it in a pan, which can kill most diseases and insects.

Temperature management

Like warm climate, but summer high temperature, muggy (more than 35 ℃, air relative humidity more than 80%) environment is not conducive to its growth; the winter temperature is very strict, when the ambient temperature is below 10 ℃, it can not safely survive the winter when the frost occurs.

Pest control

Green onion orchid is mainly damaged by insect pests, such as onion orchid night moth, mainly harmful to onion orchid, red red, Lycoris and other plants, is a secondary pest. When Spodoptera litura is serious, it can eat up all the aboveground stems of onion orchid. Although the stems and leaves of onion orchid were eaten by the insect, the aboveground part could still germinate and grow, without causing the death of onion orchid, but its growth potential was obviously weakened.

Prevention and cure method

Turn the ground in winter or early spring, dig out the overwintering pupae and reduce the population number; when the larvae occur, spray 1500 times of rice, 1500 times of Lesbon or 800times of phoxim EC, and choose to spray when the larvae come out in the morning or evening. The control effect is better.

Culture methods and matters needing attention of onion orchid growth habits of onion orchid

Green onion orchid, also known as onion lotus, leek lotus, liver herb, etc., is a perennial herb of Lycoris family, native to South America, and is now planted all over China. It is often used as a border material for flower beds, and it is also suitable for green space cluster planting. It is most suitable to be used as a ground cover plant in the lower half of the forest or planted beside a courtyard path. Today, the editor of wed114 wedding network brings you the breeding methods and matters needing attention of onion orchid, and shares the growth habits of green onion orchid.

Culture method of onion orchid

1. Environment: choose places where the wind is sunny and the soil is fertile and moist. Keep the soil moist during the growth period. If yellow leaves and residual flowers are found during flowering, they should be cut off and removed in time to maintain beauty and avoid consuming more nutrients.

2. Potted soil: potted soil is very important. Cohesive soil, powdery soil and alkaline soil are not suitable to raise orchids, because these soils are not conducive to rooting, not easy to drain, and poor ventilation. Planting orchids with this kind of soil will form stiff seedlings with short roots of grass.

3. Watering: onion orchids should be watered adequately during the growth period, and it is appropriate to keep the basin soil moist, but not stagnant water. When the weather is dry, water is often sprayed on the leaves to increase air humidity, otherwise the leaf tips are easy to yellow and wither.

4. Fertilization: green onion orchid requires more fertilizer and water as other grass flowers, and it can grow well and bloom luxuriantly after topdressing 2 or 3 times a year. After fertilizing, keep the leaves and flowers dry at night.

5. Temperature: green onion orchids like a warm climate, but the hot and muggy environment in summer is not conducive to growth. The temperature in winter is very strict, and the growth stops when the ambient temperature is below 10 ℃, so it can not survive the winter safely when the frost occurs.

Points for attention of green onion orchid

1. Fertilizer application: onion orchid requires more fertilizer and water, but is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer. It is required to follow the principle of "frequent application of light fertilizer, less and more times, and complete nutrition".

2. Watering essentials: onion orchid should be well watered during the growing period, and the basin soil should be kept moist, but not stagnant water. When the weather is dry, water is often sprayed on the leaves to increase air humidity, otherwise the leaf tips are easy to yellow and wither.

3. Pot soil replacement: onion orchids are usually not specially turned into pots, but are replanted every year when combined with ramets. At the bottom of the basin, a thick matrix of 2 cm and 3 cm was placed as the filter layer, and then the plant was put in.

4. Pest control: onion orchid is mainly harmed by leaf withering disease, which is controlled by spraying 65% Daimen zinc wettable powder 600 times. Pests include Plutella xylostella and thrips, which can be sprayed with 2.5% deltamethrin EC 4000 times.

Growth habits of onion orchid

Green onion orchids like fertile soil, like sufficient sunshine, resistant to semi-shade and low humidity, and should be fertile, sticky and well-drained soil. It is hardy, it can keep evergreen in the Yangtze River basin, and it can survive for a long time below 0 ℃. Under the condition of about-10 ℃, it will not be frozen for a short time, but it may freeze to death for a long time. Green onion orchid is very easy to divide balls naturally, and it is easy to propagate, so it is necessary to pay attention to the proper protection against cold in winter.

Propagation methods of onion orchid

1. Ramet: the ramet of onion orchid is carried out after the soil is thawed in early spring, and the mother plant is taken out of the flowerpot, shaking off the excess potted soil, separating the root system as much as possible, and cutting it into two or more plants with a sharp knife. each plant should have a considerable root system, and its leaves should be pruned properly to facilitate survival.

2. Sowing: about 20 days after the onion orchid becomes hot, the seeds should be harvested in time, and the most suitable temperature for sowing is 15: 20 ℃. The seeds are often sown in autumn after mid-late September, and the seeds are glued to the surface of the substrate one by one, covering the substrate 1 cm thick. Later, when the basin soil is slightly dry, it will be watered again, but the watering strength should not be too strong, so as not to rush the seeds.
