Planting Methods and Cultivation Techniques of Onion

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 now it is planted all over China, often used as the edge material of 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 the courtyard path. Let's take a look at the breeding methods and matters needing attention of onion orchid.

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.

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.

Cultivation and maintenance methods of onion orchid

Onion orchid is used for ground cover plants, or for flower beds, lace, under the forest, but also for pot cultivation and extensive management. Green onion orchid, like fertile soil, resistant to semi-shade or low temperature environment. The main methods are ramet and sowing, but in order to blossom in the second half of spring planting, separate planting bulbs have the greatest grasp. Onion orchid is easy to divide balls naturally and propagate easily. Cultivation in Huang-Huai area should pay attention to proper protection against cold in winter.

In the hot summer season (the daytime temperature is above 35 ℃), if it is maintained in direct sunlight, it will grow very slowly or go into a semi-dormant state, and the leaves will slowly turn yellow and fall off due to burns.

Therefore, it should be shielded from about 50% of the sun in the hot summer. Put in indoor maintenance, as far as possible in places with bright light, such as well-lit living room, bedroom, study and other places. After indoor maintenance for a period of time (about two months), it should be moved to an outdoor place with shade (heat preservation in winter) for a period of time (about a month), so alternately. Usually, it is not specially turned into a pot, but is replanted every year when it is combined with ramets.

Green onion orchid, like other grass flowers, 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 two fertilization principles of "frequent application of light fertilizer, less and more times, complete nutrition" and "dry and wet, dry, not watered, irrigated", and after fertilization, leaves and flowers should be kept dry at night.
