Leek is a common vegetable, it has rich nutritional value, delicious taste, and is loved by many people. So, how are leeks grown?
1. Preparation before planting.
Growing leeks requires choosing fertile, well-drained soil and deep turning and drying before planting to improve the soil's permeability and drainage. At the same time, in order to ensure the growth and yield of leeks, it is necessary to apply an appropriate amount of organic fertilizers, such as chicken manure, cow manure, etc.
2. Seed selection and sowing.
Choose healthy, disease-resistant, high-yielding varieties of leeks, such as green leeks, snow leeks, etc. Before sowing, seeds need to be screened and treated, such as disinfection with 50% carbendazim wettable powder, to reduce the occurrence of pests and diseases. When sowing, it is necessary to control the sowing density and depth, generally using strip sowing or spreading, and the sowing depth is about 3-5 cm.
3. Field management.
During the growth period of leeks, delicate field management is required. At the seedling stage, it is necessary to keep the soil moist and promote the growth of seedlings. During the growth period, regular fertilization, watering, weeding, and pest control are required. In order to improve the quality and yield of leeks, some special measures can also be taken, such as shading, mulching, etc.
4. Harvesting and storage.
When the leaves of the leeks grow to 30-40 cm, they can be harvested. When harvesting, the stubble height needs to be moderate, generally 5-10 cm high. After harvesting, the leeks need to be washed and treated to remove impurities and residues. In order to prolong the storage time of leeks, they can be stored by means of refrigeration or vacuum packaging.
In short, the cultivation of leeks requires careful management in multiple links, including soil preparation, seed selection and sowing, field management, harvesting and storage, etc. Only by doing a good job in the management of each link can we grow healthy and high-quality leeks.
