Chives seeds out of seedlings good planting methods are as follows:

1, leek growing environment

1, leeks love the cool climate, the germination of the appropriate temperature of 15-18 ℃, lower temperatures of 2-3 ℃; seedling growth of the appropriate temperature for the 12-18 ℃, temperature More than 25 ℃ when the growth of slow; leaf growth at a suitable temperature of 15-25 ℃, generally at 10-15 ℃ can also grow.

2, leeks do not tolerate high temperatures, when the temperature exceeds 25 ℃, plant growth is slow, the temperature is higher than 30 ℃, the leaves will be yellow, and even withered; in the -6 - 7 ℃ of the low-temperature environment, the leaves will begin to die; underground rhizomes in the -40 ℃, but also still can be safe for the winter, but the varieties of the southern region, the above-ground parts of the more resistant to cold temperatures, the underground part of the resistance to low temperatures is weak.

These are the most important of all the varieties of the plant.

2, leek seed pre-sowing preparation

Select sandy loam and dry land for nursery, deep plowing and sunbathing before sowing, the use of the sun can be high-temperature disinfection, or low-temperature to kill the eggs of pests and diseases, and then whole fine harrowing, made into a flat bed of 1.5m × 8m.

Each square meter of bed spread rotted chicken manure or pig manure 5-7kg, or humic acid eco-fertilizer 8kg, urea 0.1kg, avidin 0.05kg, 50% carbendazim wettable powder 0.02kg, soil and fertilizer should be mixed evenly, and then leveled.

3, leek seed treatment

Selecting high-quality seeds, generally in the early spring when temperatures are low, you can use dry seeds for sowing, in order to grab moisture out of the seedlings can be soaked to germinate.

First of all, you can sunbathe the seeds for 1-2 days before seed treatment, 1-2 days before sowing, put the selected seeds, put them in 40 ℃ of warm water, stirring well, fishing out and scrubbing clean, and then change the 30 ℃ of warm water to soak the seeds for 8-10 hours, and then put them into 18-20 ℃ to germinate the environment, and then wash them with water 2 times a day, and then wait until 60% of the embryonic roots extend out when you can sow the seeds.

4, leek seed sowing method

Yellow and Huaihe River Basin spring sowing leek time for the first half of April to mid-April, the southern region for the December-February, the northern region for the May-June, when the local temperature stabilized above 12 ℃, the average daily temperature of 15-18 ℃ can be sown.

Generally can be used strip sowing, per mu seedbed sowing dry seeds 6-8kg, can be planted 6000 square meters of vegetable land, after sowing the need to cover the film, is conducive to heat preservation and warming, when 70% of the seedlings top soil and then uncover the film.
