Onions of white flowers are of some value, and they are suitable not only for green cultivation but also for home planting. The following is a short presentation of the method used to plant onions。
Crop
Some 20 days after the orchid, seeds mature and are collected in a timely manner, as they were growing on plantations during the rainy season. Owing to the long-term fear of heat throughout life and the best temperature for sowing at 15-20°c, it is often broadcast after mid-september。
Seeding
For small seeds that are difficult to trap with hands or other tools, one end of the water used for toothpicks can be wet, a piece of the seed can be glued to the surface of the matrix, covering 1 cm thick, then the seeding basin can be placed in the water at a depth of 1/2-2/3 at the height of the flower basin, and the water can be immersed slowly (referred to as “basket leaching”); for larger seeds that can be caught with hand or other tools, the seeds are placed directly in the matrix at a distance of 3 x 3 cm. After broadcast, cover the matrix with a thickness of 2-3 times the size of the seed. The seeding matrix can then be wet with sprayers and pyrotechnic flowers and then water when the pelvis is dry, so that the water is not so intense as to prevent the seeds from being washed up。
Management after seeding
After planting in the autumn, when cold tides are encountered, the flower basins can be wrapped with plastic film to protect the temperature and humidity; when a seedling is released, the film shall be removed in time and the seedling shall receive the light of the sun before 9. 30 a. M. Or after 3. 30 p. M., otherwise the seedling shall grow very soft; when most seeds come out, proper seedlings are needed: sick and unhealthy seedlings are uprooted, leaving space for each other; when most of the seedlings grow three or more leaves, they can plant them。
In fact, white onions can be planted in water tanks, but they can be beautiful when they grow to a certain height. The way in which onions are treated in different parts of the country is not the same, so care must also be taken that they are adapted to local conditions and that science is growing onions that produce beautiful flowers。
