When cultivating leeks, seeds should be selected according to the region where they are located, and those with good quality, strong disease resistance and high yield should be selected. Sowing seeds is very simple, just spread them directly on the soil surface and cover them with soil and compact them. The seedlings can be transplanted when they reach 18 to 20 centimeters. Before transplanting, the soil must be prepared and base fertilizer applied. Pay attention to the setting time and avoid seasons of high temperature and humidity. In addition, management must be strengthened after planting to ensure sufficient water and nutrients.

1. Variety Selection

When cultivating, you need to select seeds according to the region. Different varieties have different dormancy habits, and they should be selected according to the time on the market and the method of succession. Choose those with better quality, strong disease resistance, and high yields.

2. Sowing method

Sowing Be sure to spread the seeds evenly when planting, and cover them with soil after sowing. Cover them with about one centimeter of soil, and compact them after covering. The seedlings must be kept moist before they are unearthed, and management must be strengthened during the seedling stage, and weeding must be carried out frequently. The seedlings can be transplanted when they reach a height of 18 to 20 cm.

3. Land preparation for border cultivation

It is a perennial vegetable and does not need to be plowed for many years after cultivation. Therefore, the soil must be prepared before planting. The plot must be plowed deeply first to ensure that the root system of the seedlings can develop better. Fertilization is also required, with 5 tons of farmyard manure, 40 kilograms of diammonium phosphate, and 10 kilograms of potassium sulfate per acre, and rotary tillage twice to ensure better mixing of fertilizer and soil.

IV. Colonization method

Colonization To avoid high temperature and high humidity seasons, those planted in spring should be planted after the Summer Solstice, and those planted in autumn should be planted after Qingming Festival. The method of furrow planting can be used. The row spacing is guaranteed to be 30-35 cm, and the trench is 10-15 cm deep. After digging the holes, plant 20-40 plants in each hole.

5. Strengthen management

Management must be done well after planting. In the later stage, watering and top dressing should be done frequently to ensure sufficient water and nutrients, so as to promote better growth of seedlings. Especially around the beginning of autumn, when seedlings are in their prime growth period, they need to be watered every other week and top-dressed with quick-acting nitrogen fertilizer.
