Detailed explanation of practical cultivation techniques of leek

Leek is rich in nutrition, contains vitamins, minerals, sugar, protein and cellulose, and unique flavor, can enhance appetite, so it is deeply loved by the broad masses. Leek is a perennial vegetable, from planting to the end of stubble cultivation usually takes 3-5 years, some as long as 8-10 years. The practical cultivation techniques of leek are explained in detail as follows:

1. Practical cultivation techniques of leek

1. The time and method of planting leek

Chives like cold, cold-resistant, but also heat-resistant, generally speaking, after the soil is thawed to the Autumn Equinox this period of time can be sown, most areas are mainly spring sowing. The sowing method was strip sowing, and the plastic film was covered immediately after sowing, and the film was uncovered when a large number of seedlings were covered with top soil.

2. Fertilization and watering of leek

If you want to lay a high yield foundation for leek planting, you must apply sufficient base fertilizer before sowing, but the fertilizer must be completely fermented and mature. The sowing depth should generally be controlled within 2cm, and the sowing density can be appropriately larger. After sowing, the seedlings should be watered thoroughly, and if you see the soil surface dry before emergence, the seedlings can be fully watered in about 15 days.

3. Daily management of leek

The daily management of leek is relatively simple, basically only weeding and watering can be done, but if you want it to grow fast and strong, the fertilizer must keep up with it. When the leek grows to the height above 10cm, you can top fertilizer at this time, and the fertilizer to be applied is mainly nitrogen fertilizer. Topdressing is the key to the growth and firmness of leeks every time they are watered, and every time they are cut.

4. Field management of leek

When the new leaves of leek are issued, the seedlings should be watered slowly, and the soil moisture should be preserved by ploughing to keep the soil dry and wet. After autumn, when the leek is growing at its most exuberant, it is necessary to fully supply fertilizer and water. After that, the temperature gradually decreased and the plant grew slowly, so as to keep the surface dry, and then turned to the stage of arch shed management after frost.

5. The main points of harvesting leek

Although leek is harvested by stubble, its harvest interval must be paid attention to, generally not less than one month. In the last crop of leeks in autumn, the harvest of leeks should be stopped, mainly to prepare for the winter dormancy of leeks.

Second, how can chives survive the winter safely in winter?

1. Water

The water here is mainly the insulated water of leek. Only when the water is fully irrigated can leek grow better in the cold winter. Farmers need to be sure of the timing of watering water, and it is not allowed to be too early or too late. If it is too early, the water will be absorbed very early, thus not achieving the goal of using water to keep the soil from freezing. After that, the leek field will be frostbitten first, and then you will water it, which will not only fail to prevent the leek frostbite, but also make the leek frostbite problem more serious, resulting in the death of the leek root system.

Therefore, according to the different temperature in each planting area, the best time to water this time is in the first 10 days of December of each year, and the temperature is generally 5 degrees.

2. Fertilizer

Even in winter, leeks still need a certain amount of fertilizer. The advantage of fertilizing in winter is that it can promote the leek to turn green and make it grow better in spring. The general use of human feces to fertilize on it, the appropriate amount per mu, about 3000 jin.

Finally, to remind you of two points that are easy to forget, ridging and straw mulching can also play a role in preventing frost. Proper ridging can protect the roots of leeks in the cold winter. in winter, it is almost enough to ridge three times. to put it bluntly, it is to accumulate the soil between leeks to the roots of leeks. Covering the leek field with straw can make the leek better anti-freezing and moisturizing.
