The method of planting leeks is to process seeds, prepare soil, and plant and maintain them; the precautions for planting are to pay attention to the planting time.

1. How to grow leeks

1. Handling seeds

When planting leeks, you must choose plump and healthy seeds. The requirements are that they have a round and plump appearance and no If there are obvious lesions and insects, then put them in clean water and drip some nutrient solution. Leave them for about 3-5 days. Maintain a good ventilated environment and avoid direct light. They will germinate in about 5 days.

2. Prepare the soil

The soil used to plant leeks must maintain good water permeability. Generally speaking, humus soil, garden soil, pond mud, fine sand, etc. are used. Mix evenly, and finally add some decomposed farmyard manure as base fertilizer. This kind of soil has the characteristics of loose porous, good drainage and air permeability, and is suitable for the growth and development of leeks.

3. Planting and maintenance

Sow the seeds that have been soaked and germinated separately into the soil, distribute them evenly, there should be a certain distance between the seeds, and then cover them with a Layer a thin layer of soil and water until the soil is moist. When the seedlings are 5 cm high, reduce the amount of watering. Start topdressing when the seedlings are 10 cm high. When the seedlings are higher than 15 cm, start water control and pull out weeds.

2. Precautions for planting leeks

If you want to plant leeks, you can actually do it all year round. The principle of planting is that it should be done early rather than late in spring, and the seeding amount in summer should be One-third larger than that in spring, and the amount of seeds planted in autumn is twice that of spring. Mainly planted in spring and autumn, the yield of leeks in these two seasons will be greater.

Field management methods of leeks

1. Weeding methods

After the leeks are sown, manual weeding should be carried out in time when the seedlings emerge to remove diseased plants. . You can also use herbicides such as Quizalofop and Gacaoneng to control monocotyledonous weeds, or spray the border surface with 100-150 grams of 30% Herbicide EC per mu mixed with 50 kilograms of water after sowing and before emergence.

2. Watering and fertilizing

Leek planting in early spring is prone to insufficient moisture. In this case, it is necessary to water the greening water in time. At the same time, combined with watering, quick-acting nitrogen fertilizer is applied 2-3 times, and urea is applied 6-8 kg per acre. Harvesting is generally not done before planting to promote root growth of leek seedlings.

3. Pay attention to soil cultivation

Because leeks have the characteristics of root jumping, soil cultivation work cannot be ignored. Before winter (after winter flower buds differentiate), a large soil cultivation should be carried out in combination with the application of overwintering fertilizer to promote growth, so that the plant can accumulate more nutrients for normal bolting in the coming year. Usually, 1-2 small cultivations can be carried out in a planned manner. earth.
