How to plant leek seed (seed) and how to plant and germinate quickly

First of all, sandy loam and dry land are selected as seedling grounds to select high-quality seeds, generally, dry seeds can be used for sowing when the temperature is low in early spring, soaking and sprouting can be carried out in order to sprout seedlings, the local temperature is stable above 12 ℃, and the daily average temperature is 15-18 ℃.

First, the growth environment of leek

1. Leek likes cool climate, the suitable temperature for germination is 15-18 ℃, and the lower temperature is 2-3 ℃; the suitable temperature for seedling growth is 12-18 ℃, and the growth is slow when the temperature exceeds 25 ℃; the suitable temperature for leaf growth is 15-25 ℃, which can also grow at 10-15 ℃.

2, leek is not resistant to high temperature, when the temperature is more than 25 ℃, the plant grows slowly, when the temperature is higher than 30 ℃, the leaves will turn yellow, even wither; in the low temperature environment of-6 ℃ 7 ℃, the leaves will begin to die; the underground rhizome can survive the winter safely at-40 ℃, but the varieties in the southern region are more tolerant to low temperature, and the underground part is relatively weak in low temperature tolerance.

Preparation of leek seeds before sowing

Select sandy loam and dry land as nursery land, plough deeply before sowing, use the sun to disinfect at high temperature or kill disease and insect eggs at low temperature, then fine rake flat beds of 1.5m × 8m, sprinkle 5-7kg of rotten chicken manure or pig manure, or humic acid ecological fertilizer 8kg, urea 0.1kg, Awei ground net 0.05kg 50% carbendazim wettable powder 0.02kg, soil and fertilizer should be mixed evenly. And then flatten it.

Seed treatment of Chinese chive

To select high-quality seeds, generally, when the temperature is low in early spring, dry seeds can be used to soak seeds to sprout. First, you can sun up the seeds for 1-2 days before seed treatment, and 1-2 days before sowing. Put the selected seeds in 40 ℃ warm water, stir well, remove and scrub clean, then soak the seeds in warm water for 30 ℃ for 8-10 hours, and then put them into 18-20 ℃ environment to accelerate germination. Rinse with clean water twice a day, wait until 60% of the radicle protrudes before sowing.

Fourth, the sowing method of leek seed.

The spring sowing time of leek in the Huang-Huai River Basin is from the first ten days of April to the middle of April, from December to February in the south and from May to June in the north. The local temperature is stable above 12 ℃, and the daily average temperature is 15-18 ℃. Generally, strip sowing can be used to sow dry seeds 6-8kg per mu, and vegetable fields can be planted. Plastic film is needed after sowing, which is beneficial to heat preservation and temperature raising.

Fifth, leek seedbed management

After finishing the seedling until the seedling height is 16cm, water can be watered every 7-10 days, combined with watering, the rotten human feces and urine or humic acid ecological fertilizer 50kg is applied per mu, and then 33% of the fertilizer is sprayed on the surface. After emergence, the leek seedlings need to be transplanted and planted in the field after germination.
