Leek is a common ingredient in our life. We need to pay attention to a lot when planting leeks. Although leeks are easy to survive, if we want to plant well and meet the market demand, we need to plant carefully and pay attention to methods. Let's tell you the planting method of leek.
1、 Variety selection
All varieties of leek can be potted, but it is best to choose varieties with strong growth ability, such as 791 leek and Korean leek, which can be sown and cultivated, or directly planted with leek roots.
2、 Selection of basin and basin soil
Tile pots, ceramic pots and plastic pots can be selected, but flowerpots with good appearance, light texture, water permeability and good air permeability are better. When planting indoor balcony, the flowerpot shall be provided with a bottom plate to prevent seepage during watering and affect the sanitation of the balcony. The diameter shall be more than 20cm, and there shall be seepage holes at the bottom. The root growth of potted leek is limited due to the limited container space. Therefore, the cultivation soil in the basin must contain sufficient fertility to maintain the needs of continuous growth and continuous harvest of leek. The proportion of general culture soil is 3 parts of rotten leaves, 2 parts of rotten livestock manure and bone meal, 5 parts of high-quality farmland soil, or 5 parts of rotten farm manure, 3 parts of garden soil and 2 parts of sandy soil. When entering the basin, the basin bottom hole is covered with 1-2 pieces of broken tiles, filled with a little coarse sand, and filled with nutrient soil to 2-3cm from the basin edge.
3、 Seeding and seedling raising
Seedling management: promote growth in the early stage, properly control water in the later stage, and squat seedlings to promote roots. Main measures: first, water frequently and shallow, and water once every 3 ~ 5 days according to the soil condition; Second, weeding and timely removing weeds in the border; Third, apply fertilizer appropriately. When the seedlings grow to 10 cm high, apply quick acting nitrogen fertilizer once or twice. In order to cultivate leek roots, they were not harvested in that year.
Leek can be planted on the balcony in spring, summer and autumn or settled with leek roots. It is best to use the new species of the year for sowing and seedling raising from mid April to early May. First pour enough bottom water into the flowerpot, then sow after water infiltration, cover it with 1cm thick nutrient soil, always keep the surface of the basin soil moist without hardening, and water it appropriately according to the situation of the basin soil after emergence. Leek roots should be planted in spring. Due to the limited space, the planting density of leek in the basin should not be too large. Water in time after planting to promote the survival of seedlings.
4、 Daily management
When the new leaves are sent out, the seedling water shall be poured in time according to the dry and wet conditions of the basin soil, and the basin soil shall be cultivated to preserve moisture. Always keep the soil moist. After autumn, the weather is getting cooler and cooler, which is suitable for the vigorous growth of leeks. It is necessary to fully supply fertilizer and water. Generally, water is poured once in 4 ~ 5 days, and topdressing is carried out 3 ~ 4 times. For top dressing, put sesame cake, bean cake and other fragments into sealed containers for fermentation, take the rotten upper liquid, add 10 ~ 15 times of clean water and apply it to promote the growth of leaves, so as to lay a good foundation for the expansion of bulbs and the growth of roots. After that, the temperature will continue to decrease and the plant will grow slowly. Reduce watering appropriately and keep the basin soil dry. According to the growth situation in the planting year, it can be harvested appropriately when the growth is strong, but not when the growth is weak. Focus on root cultivation. Change the basin soil every 2 years, which should be carried out in the dormant period in winter.
5、 Timely harvest
The yield of leek is low in the first 1 ~ 2 years after planting, and the peak growth period is 3 ~ 6 years, with the highest yield. It enters the aging stage after 10 years, so it should be transplanted in time. The number of harvests per year depends on the growth, fertilization and market conditions of leeks. Taking 7 leaves and 1 heart as the standard for cutting leeks, it is best to harvest in the morning, and it is better to cut to the yellow leaf sheath of 3 ~ 4cm on the bulb. In the future, each knife should be slightly higher than the previous crop in order to ensure normal growth.
