Spring and autumn are good seasons for growing leek, when the leek grows well and tastes the best, and now it is the seedling period of leek. So how to raise leek seedlings in autumn? Let's have a look with the editor.

1. Seed treatment

Leek seeds should choose varieties with high germination rate, good variety and good disease resistance, and soak the seeds properly before sowing, which can appropriately improve the germination speed of the seeds. 4-5 days before raising seedlings, the seeds can be soaked in 35 degrees warm water, and the bad seeds and shrunken seeds can be removed in the process of soaking. In the process of seed soaking, the seeds can be continuously stirred until the water temperature cools and then soaks for about 24 hours. After soaking, remove the seeds, put them in an environment of 15-20 degrees to promote germination, germinate in 2-3 days, and then sow.

2. Seedbed preparation

In open field cultivation, the nursery bed should select plots with good drainage conditions, ventilation and good irrigation conditions, and the soil should be treated well before raising seedlings. For those ploughing and fertilization treatments, about 4000 kg of mature farm manure should be applied per mu, and the soil can also be disinfected if possible. If the seedling is raised with a hole plate, the seedling substrate can be made of peat, vermiculite and perlite. It is necessary to ensure that the substrate is loose and breathable, and base fertilizer can also be added to the substrate.

3. Sowing and raising seedlings

In order to raise seedlings, we should choose the hole plate according to the seedling size, 5 leaves of the seedling, use the 288-hole hole plate, if the seedling has 6 leaves, choose the 128-hole hole plate. Put the seeds into the hole, the depth should not be too deep, so as not to affect the seedlings unearthed, after sowing can be covered with a thin layer of soil, and then watered again. Sowing in the field can be used to sow or sow in the field, keep the seed spacing at about 10 cm, control the depth at 1.5 cm, and water after sowing.

4. Seedling stage management

Generally, seedlings can emerge within a week after sowing, and it is best to control the temperature in the seedling stage. The suitable temperature for seed germination is 15-18 degrees. In the later stage, with the germination of seeds, the temperature can be increased appropriately, and the highest temperature should not exceed 25 degrees. The light should not be too strong, when the light is too strong in the autumn afternoon, the sun can be properly shaded, the substrate should be kept moist, and the drought phenomenon should not be traveled. Foliar fertilizer should be applied 1-2 times when the seedlings grow to about 30 cm, and 0.1% urea is suitable.
