A brief description of the iron onions
Iron onions are a common and easy-to-cultivated vegetable, which is popular because of their thick, fine and nutritious size. Iron onions are also a mutation of round onions, which tastes sweeter than round onions and is especially suitable for cooking soup or cooking. Onion seedlings of iron poles are produced for long periods of between 90 and 110 days, often in the spring。
Soil selection of the method of planting iron onions
Iron pole onion seedlings are less picky, but it is preferable to choose fertile, well-drained, well-ventilated soils with a ph value between 6. 0 and 7. 0。
Seeding
Iron onion seedlings are generally seeded in the spring. First, there is a need to select seeds suitable for planting. The ditches are then opened on the selected soil, which is about 2-3 cm deep. Spread the seeds evenly on the bottom of the ditch and cover them slightly with soil。
Management
A proper amount of water and pine soil is required before the onion seedlings of iron poles can be produced in the long term. In addition to this, appropriate application of fertilizers is required in the later stages of growth to achieve good harvest results。

Iron onion seedlings are generally available on the flower gardening market or online. It is a horticultural market that specializes in the sale of a variety of plants and flowers, where you can find the big onions of iron that you need and receive technical expertise in the purchase process。
Care to water the conservation techniques of iron and onion seedlings
The water requirements for the soil are higher in iron rods and onions. Growing up requires an adequate amount of water per week from one to two times, but it can be jeopardized by overwatering or water scarcity. It is particularly important to note that, in the case of high soil moisture during the 15 to 20 days following seeding, the frequency of water recharge should be appropriately reduced in order to avoid plant weakness。
Fertilizer application principles
The nutritional needs of onions from iron poles are high and require the timely application of fertilizers. Fertilizers and fertilizers can be distributed, but the principle of fertilisation is usually concentrated at least 15 to 20 centimetres above the ground. It should be noted that there is a difference in demand for potassium nitrogen phosphorous in iron rods and that overweight can damage its quality。
Insect pest control
Iron poles have shallow roots of onion seedlings, and the leaves are standing up and vulnerable to various pests. Common pests include bee jumping, leaf worms, roll moths, cinderella-like aphids, etc. Effective prevention includes increasing the content of strains of antibiotics and limited physical or chemical treatment. More importantly, good sanitation is maintained to prevent the occurrence of pests and diseases。
