Long-Day onions are onions that require 14 or more hours of continuous daylight, for northern growers.
Sow directly in the field or early in containers. Cut plants back by half if they stretch in containers. Allium cepa unless otherwise noted.
(Utah Strain) White Sweet Spanish onion is mild, sweet and tasty. This variety is white fleshed and has a thin neck. Good winter keeper. Produces fruits weighing 1 lb. 110 days.
Germinate the seeds before sowing in weather below 20 degrees, so that the seeds have a high germination rate and grow faster than direct sowing.
Germination is very simple, first soak the seeds in warm water (40-50 degrees) for a day, and then wet with paper towels or towels, spread the seeds evenly on top of the seeds covered with a layer, and then put in a warmer place or outside in a thicker towel wrapped up can wait for the seeds to germinate, different varieties of germination time is not the same. (Spring, summer and autumn planting only need to first soak the seeds for 1 day directly planted can be)
After germination and planting, after germination, prepare for planting, first loosen the soil, level it, and sprinkle it with fertilizer. Sow the seeds evenly on the shishi, and then cover the top of the seeds with 1.5-2 cm thickness of soil. Then watering (the amount of watering to the degree of wetness of the soil, watering a little more wetness) planted inside the pot can be covered with film to play a thermal insulation
The effect is to promote the rapid growth of seeds, planted in the ground also use this method of covering film insulation.
There are two methods of fertilization: (1) Base fertilizer is fertilizer applied to the soil before sowing or transplanting, usually organic fertilizer. It is usually organic fertilizer. (2) Fertilizer is applied during the growth of plants, and watering and irrigation are used to make the plants grow fast and resist diseases. (2) Follow-up fertilization is to fertilize the plants during the growth process and to water and irrigate them to make them grow quickly and to resist diseases.
Fruit and vegetable cultivation
1. Seedling planting
Use seedling boxes or disposable paper cups
Fill with soil and water and sprinkle 3-4 seeds
After the seedlings have grown 3-4 leaves
Transplant into large cultivation containers
(Don't hurt the roots when transplanting)
Insert a stand along the main stem of the plant. When inserting the stand, be careful not to injure the roots of the plant.
Take pollen from the stamens with a cotton swab
Pollinate the pistil
(flowers with stamens and pistils)
The fruits show the characteristic color of the variety
Ready to harvest
Growing leafy vegetables
1. Trenching and watering
Flatten the surface of the soil and water it thoroughly until the bottom overflows, then make a small trench about 0.5 cm deep and 0.5 cm wide.
Soak the seeds for 3-5 hours. Place 1-2 seeds at 2 cm intervals, paying attention to Do not let the seeds overlap.
Cover with 0.5 cm of fine soil and spray wet.
After germination, interplant the seedlings, even if the plants are 5-10 cm high.
Fertilize the plant after 3-4 leaves have spread, scattering it between the trenches and mixing it with the seedlings.
The outer leaves are harvested at once when they have expanded by 10-20 leaves. It is also possible to leave new leaves and repeat harvesting several times.
