Summary: How does leek survive winter safely? How to manage dormant leeks?

Now the weather has become colder and colder, and fewer and fewer vegetables can be planted. However, some perennial vegetables still need to pay attention to the problem of overwintering, such as leek mentioned today. How to manage leek in winter? Here, science and agriculture will share with you some questions about the winter management of leek.

Winter chives overwintering management

The problem of hanging leek in winter is divided into open-air planting leek and protected land planting leek. Here, let's talk about the management of leek wintering separately.

First of all, the problem of overwintering leeks in the open air

Although the open-air leek is no longer harvested in winter, winter is an important season for leek management, and the yield and quality of leek in the coming year can be guaranteed only if winter management is good.

Watering, watering mainly refers to the freezing water of leek, this time the water is well watered late leek can better winter. Watering time growers need to grasp well, too early too late are not suitable, premature watering because water has been absorbed, did not achieve the role of moisture preservation and antifreeze. Watering too late will cause serious freezing damage to leek field, which not only does not play the role of anti-freezing, but also makes leek freeze damage more serious, even causing leek root death.

Therefore, the watering time is very critical. Different preparations need to be made according to the temperature of different planting areas. Generally speaking, watering starts in early December every year. At this time, the temperature generally starts at about 5 degrees Celsius.

Soil fertilization, winter although leek into dormancy period, at this time or need appropriate fertilization, winter fertilization is generally called "wax fertilizer", at this time fertilization can play a role in promoting leek spring green, promote growth. Generally suitable for the application of decomposed human urine manure as winter fertilizer, each mu can be used about 1500 kg. In addition, it is the problem of soil cultivation. Because the winter temperature is low, proper soil cultivation can protect the roots of leek. Generally, it takes about 3 times of soil cultivation in a winter. When cultivating soil, it is only necessary to accumulate the soil between leek rows to the roots of leek.

In addition, in order to prevent leek freezing injury, you can cover the leek field with hay, which can play the role of freezing prevention and moisture preservation.

Management of greenhouse leek

Although leek is in dormant period in winter, the demand for leek in winter is still very large, because everyone likes to eat dumplings in winter, leek as the main stuffing of dumplings is naturally very popular, so many growers will adopt protected land to plant anti-season leek in winter.

First of all, it is best to choose the most suitable leek varieties for winter in greenhouse, and choose the leek varieties with strong cold resistance. The second is the most critical problem_leek buckle shed, buckle shed before the need to do enough preparation work, timely leek clearing work. After clearing the ridge, it is necessary to peel off the soil at the root of leek, which is conducive to breaking the dormancy period of leek. After these works are completed, it is necessary to irrigate the roots of leeks, because leeks are easy to produce leek maggots after the shed is closed, and fertilize and water the roots after irrigation.

After the above work is completed, it is generally possible to buckle the shed about three days later. After the shed is buckled, the leek is easy to suffer diseases. Attention should be paid to the proper ventilation and disinfection of the greenhouse. The temperature in the greenhouse should be guaranteed between 20 degrees and 25 degrees. Generally, the first crop of leek can be harvested in 20 days to one month. After harvesting, topdressing and proper watering are needed about three days later.
