How to manage open field leek in spring

How can we grow high-yield and high-quality leeks? The main points of spring management of open-field leeks are introduced as follows:

1. Apply organic fertilizer

Applying organic fertilizer in spring is a major event in the production of open leek. Spring is the best season for fertilizing leeks in the open field. Due to its long growth period and the need for a large amount of fertilizer supply, it is necessary to apply organic fertilizer for a full year in the spring. Add long-acting all-round fertilizers such as bean cake, sesame cake, cottonseed cake, etc., mixed with rotted organic fertilizer, the depth is 15 ~ 20 cm, then covered with soil to step on the ground, loosen the soil, smooth the border, remove dead leaves, and spread 2 cm thick sand , It is helpful to cut out the leek and grow the leek stem. Then pour the water once to prevent "ventilation" after fertilization.

2. Loose soil

After the leek returns to green, the dead leaves and weeds in the ground should be removed in time, the flat surface should be flattened, and the border should be sorted out so that the base of the plant can better receive sunlight, increase the ground temperature, and promote germination. Cultivating loose soil can increase soil temperature, promote seedling growth, and control weeds. After each harvest, the soil should be cultivated, the flat surface should be raised, and the soil should be gradually cultivated as the plants grow.

3. Fertilizer and Water Management

The amount of watering and the amount of watering the leeks depend on the weather and soil moisture at that time. When the soil moisture is good, you can water it after receiving the first knife. In addition to applying base fertilizer, leeks also need to be "knife topdressing", that is, topdressing 1-2 times after each harvest. The top dressing should be carried out 3 to 4 days after harvesting. The wounds to be harvested should be applied when the new leaves grow out. Top dressing immediately after harvesting can easily cause fatal damage. The top dressing should be based on quick-acting nitrogen fertilizer and human feces and urine, which can be applied with water or ditch. The dilute water of manure must be fully rotted to prevent maggot damage.

4. Picking roots and cultivating leeks

For leek plants over three years old, root picking and soil cultivation are also required. One is root picking, which is carried out before the sprouting of leeks. The soil of the roots is digged with iron rods, with a depth of about 6 cm each. Tiller and weaken tillers, spread the dug out soil between rows to dry, and then pinch the rhizomes, fill it with fine soil and bury it. The second is soil cultivating. The soil cultivating should be carried out before the new roots are germinated. The thickness of the soil cultivating depends on the height of the jumping root. Generally, the soil is 3 to 4 centimeters thick each year. It is required to pile up the fertile sandy loam soil after sieving and use it after warming in the sunny place.
