The latest sowing time and method of leek

Leek is a very popular vegetable with a pungent and pungent taste. However, the market in our country is still very large, because the demand for leeks is large, so now many people are growing leeks. When planting leek, we should control the sowing time of leek according to the change of season. So what is the sowing time and method of leek? The following editor will give you a brief introduction, let's have a look!

1. Spring sowing

Spring is the best time to grow leeks in most areas. Spring sowing of leek can last for a long time since the soil is thawed. When leek is sown in spring, it should not be too late. When the soil temperature is kept at 6-9 degrees, it can be sown. Because the soil is not fully permeated at this time, so the soil water content is relatively large, and the whole seedling rate is higher. In addition, the weed seeds have not yet germinated, so the leek grows faster after emergence, which can reduce the harm of weeds. In order to control the sowing time according to the region, for example, in North China, the sowing work should be completed in early May. In provinces such as Shandong, the seeds will be sown in mid-March.

2. Summer sowing

In some areas, due to various reasons, the sowing date of leek can only be delayed until summer. For example, it is not possible to sow seeds until wheat is harvested or crops such as cucumbers go on strike. However, because the summer temperature is relatively high, after sowing, the germination of leek seeds is blocked. If there is no timely shading to cool down, then the emergence rate will be reduced. Therefore, sowing in summer should be carried out by covering the sunshade net to reduce the temperature of the seedbed and maintain the soil water content. Provide a good growth environment for leek seed germination and seedlings, and it is best to sow early in summer. The amount of sowing should be higher than that of spring sowing, and the soil cover should not be too thick. Finally, it is necessary to prevent the soil from producing stagnant water.

3. Autumn sowing

The autumn sowing of Chinese chives can provide early breeding and strong seedlings for the production of leeks in the following year. Transplanting can be carried out in the spring of the following year, and attention should be paid to waiting for the temperature to drop gradually before sowing in autumn. Usually the temperature should be kept below 22 degrees, and then just before the leek overwintering, that is, when the temperature drops to about 3 degrees, it is necessary to ensure that the leek has grown for at least 50 days in order to ensure that the leek can survive the winter safely. Therefore, the suitable sowing time for autumn sowing leek should be from White Dew to the Autumn Equinox. Autumn seeds should be stored at low temperature in summer to prevent the germination rate of leek seeds from being reduced in high temperature and humidity environment.

4. Winter sowing

The temperature in winter is very low, especially in the north, if sowing in winter in the north, then it is necessary to ensure its thermal insulation performance, so the cost will be relatively high. Therefore, winter sowing is generally not recommended in the north, but if it is in the south of Guangdong. With the increase of temperature in winter, open-field cultivation does not need any heat preservation equipment, leek can grow well. Therefore, it is a suitable area for leek sowing in winter in Guangdong and other provinces.

The above is a brief introduction to the sowing time of leek. That's all for today's introduction. This article is for reference only. I hope it can help you all.
