Planting method of potted onion orchid

Only those who have seen green onion orchid, whenever there is a spirit, will be moved by her posture. Obviously born in the low place, but has the same backbone and cleanliness as Mei Xue. Green onion orchid's arrogance is not in the dry branches, nor is it proud of the snow and ice flowers, even it has no fragrant aroma, not even elegant fragrance. But its inborn attitude is like whose soul stands between heaven and earth.

Green onion orchid is often used as the edge material of flower bed, and it is also suitable for green space cluster planting, which is most suitable for ground cover plant in the half shade of the forest, or planted beside the courtyard path. The following is to introduce the planting techniques of onion orchids:

[seed collection]

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.

[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 1 foot 2 feet 2 tap 3 of the height of the flowerpot, allowing the water to 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. After sowing, you can use sprayers and fine-hole showers to wet the sowing matrix, and later, when the basin soil is slightly dry, you should still pay attention to the watering strength not to wash the seeds up.

[management]

After sowing in autumn, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and wet; 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 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.

Green onion orchids are planted in gardens, choosing sunny, warm and sheltered places, and applying topdressing 3-4 times during flowering period will be able to flourish leaves and flowers. Cultivated in the open field in the middle and lower reaches of the Yangtze River, after severe frost in winter, the old leaves withered and the bulbs could stay for the winter and blossom as usual the following year. The potted soil was mixed with 2 parts of loam, 1 part of rotten leaf soil and peat with a small amount of fine sand, and a small amount of bone powder and mature compost. Onion orchid growth period should have sufficient sunlight and moisture, a batch of flowers withered, suspended watering for 7-8 weeks and then resumed watering, so dry and wet interval, can blossom 2-3 crops in a year.

Organic fertilizer can be used once every 2-3 months to increase phosphorus and potassium fertilizer proportionally, which can promote the bulb hypertrophy and flowering of onion orchid. When the plants are clustered and crowded, the ramets must be forced. Strong in nature, drought-resistant and high-temperature resistant, easy to cultivate, and the suitable temperature for growth is 22-30 degrees. The depth of introduction and planting is slightly exposed at the top of the bulb, and the bulb is divided once every 2-3 years. After a batch of flowers fade, the water should be controlled for 50-60 days, and then the normal water supply should be restored. Such alternation of dry and wet can promote onion orchid blossom many times, which can blossom 2-3 times a year.
