1) Cultivation in spring and autumn. In the northern regions, the soil can be sown before and after thawing in spring, and autumn is generally sown after the beginning of autumn.
2) Cultivation of roots and roots. The cultivation method is the same as that for root spinach, and it is planted in early October. The seedlings pass through the winter and are harvested in the early spring of the second year. It is also possible to spine leeks like spinach. If you want to mention the city in the morning, you can also use the film "day cover" cultivation.
3) Cultivation of root sheds. Sowing in October, the second year in late February and early March can be harvested. Can also be cultivated in early spring greenhouses, the first year in November "buried" or sowing in February, the end of March to early April harvest.
4) Winter greenhouse cultivation. Sowing in October, harvesting on New Year's Day and Spring Festival.
Cultivation Techniques
1) Nursery. Live leeks are generally broadcasted, but they can also be transplanted in the same way as seedlings, or transplanted in live seedlings. By transplanting, the plants are large and neat, easy to harvest, easy to organize, easy to pack, and have a high degree of standardization. Easy to circulate.
2) Soil preparation, fertilization, and hoeing. Choose fertile loam or sandy loam with few weeds, leewards, sunny, flat, easy irrigation and drainage to obtain high-quality, high-yield products. The leek is a small-leaf vegetable ripening vegetable, and the amount of fertilizer per pod is not high, but it is best to use sufficient maturity to have fat, not to use unripe organic fertilizer, apply 3,000 kg of organic fertilizer per 667 square meters, 100 kg of compound fertilizer, fully mixed with the soil, and then made of 1.3 meters wide flat ridge, do not need to be flat, fine, do not have large ash.
3) sowing. There are two ways to sow:
1 Water first and then sow. It is suitable for cultivation in protected land, and the cultivated land is finely cultivated. In addition, the humidity in the protected area is large, and the soil surface after sowing is not easy to dry, which is favorable for emergence. First, pour in 5 to 10 centimeters of water in the entire pot. After the water seeps, the seeds can be sown. Because the leek seeds are small, they can be mixed evenly with fine soil of similar size.
2 first sowing, after watering. Firstly sow the fine soil seeds sown on the flour surface, and then suppress or use down-to-earth. If the soil is moist, it is best to water the next day so that the seeds are not easily washed away; if the soil is dry, then sowing At the time, it is advisable to slowly pour the water so as not to wash away the seeds. It is recommended to sow about 0.25 kg per 667 square meters. If the climate is not suitable, the seeding rate should be increased exponentially. When the conditions are appropriate, the seeding amount can be appropriately reduced.
4) Post-broadcast management. Before emergence, the soil should be kept moist and the temperature should be about 20°C to facilitate seedling emergence.
1 seedling, Dingmiao and planting. The conditions are suitable for the emergence of leeks about 4 days after sowing. Since the leek seeds are fine, it is difficult to evenly sow the seeds. Therefore, the seedlings should be seeded with time. When the seedlings have two true leaves, the seedlings can be started, and about 5 true leaves can be transplanted or replanted. About 10 seedlings can be listed, the final production of large plants, seedling spacing of 10 cm square. Transplanting colonization of the plant is also about 10 cm.
2 Weeding. The leek seeds are small and grow slowly in the early stage and are easily invaded by weeds. Therefore, the weeds should be promptly removed, especially in protective cultivation. In open field cultivation, herbicides can be considered for weeding.
3 moisture management. The leek seeds are small and the roots are shallow. Therefore, the soil should be kept moist during the whole growing season. However, in the winter cultivation, the moisture should not be too large, the moisture is large, the temperature is low, and the diseases are easy to occur.
4 temperature management. The open cultivation conditions are uncontrollable, and suitable seasonal planting should be selected. The temperature of greenhouse cultivation should be kept within the range of 10 to 25°C, and a low temperature below 5°C for a long time will cause the plants to pass through the vernalization and the phenomenon of early bolting occurs.
5 top dressing. Under the condition of sufficient base fertilizer, in the middle and late stages of the growth of the leeks, the rapid growth stage of the leeks can be followed by applying the available nitrogen fertilizer 1 or 2 times, and applying about 10 kilograms of urea per 667 square meters.
5) Pest control. Diseases of leeks usually have viral diseases, downy mildew, and sclerotia. Viral diseases are prone to occur at high temperatures and droughts. Downy mildew and sclerotinia diseases are prone to occur when humidity is high, and improper management of northern protected areas is prone to occur. The pests that are prone to occur are maggots, diamondback moths, yellow striped hops, and the like.
6) Harvest. The leek can be harvested in divided times, about 40 days after sowing. When the plants have 10 to 13 true leaves, they can start harvesting. Harvesting first, leaving small, especially dense areas should be harvested earlier, generally harvestable. 3 to 5 times. When the small plant is lifted and harvested, a large knife is used later to harvest the roots. Produces 1,000 to 2,000 kilograms per 667 square meters.
