White scallions have a certain ornamental value. White scallions are not only suitable for green planting, but also suitable for planting at home. The following small series introduces the planting method of white scallions.
Seed collection
About 20 days after the onion orchid, the seeds mature and should be harvested in time. Because it is in the rainy season, it is very easy for the seeds to germinate on the plants. Because it is more afraid of heat throughout the growing season, and the optimum temperature for sowing is 15-20 °C, it is often carried out in the autumn after mid-September.
sowing
For small seeds that are difficult to grip by hand or other tools, one end of the toothpick can be wetted with water, and the seeds are adhered one by one to the surface of the substrate, covering the substrate 1 cm thick, and then the seed pot is planted. Put into the water, the depth of the water is 1/2 - 2 / 3 of the height of the flower pot, let the water slowly immerse (this method is called "potted immersion method"); for the hand can be clipped by hand or other tools Seeds with larger seeds are placed directly into the substrate and spotted at a distance of 3 x 3 cm. Cover the substrate after sowing, covering a thickness of 2 to 3 times the size of the seed. After sowing, the seeding substrate can be wetted by a sprayer or a fine hole shower. After the soil is slightly dried, the water should be drenched. It is necessary to pay attention to the strength of the watering, so as not to wash the seeds.
Management after sowing
After sowing in autumn, when the cold wave is low, you can wrap the flower pot with plastic film to keep warm and moisturize; after the seedlings are unearthed, you should uncover the film in time, and before 9:30 in the morning, or in the afternoon. After 3:30, let the seedlings receive the sun's light, otherwise the seedlings will grow very weakly; after most of the seeds are out, they need appropriate seedlings: unplug the diseased, unhealthy seedlings and leave the seedlings left behind. There is a certain amount of space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted.
In fact, white scallions can also be planted in water tanks, but it can be beautiful after the plants of white stalks grow to a certain height. The methods of taking care of white scallions in different places in China are not the same, so everyone should also pay attention to local conditions, scientifically planting white flowers and green flowers, and opening beautiful flowers.
