Cultivation time, from the spring and autumn seasons to the autumn season and the autumn season; seedlings, which are selected to fill with particles, are then distributed evenly into the soil to cover a sheet of soil; seedlings, such as those grown up to 40 to 50 centimetres, can be planted in the first half of june; field management, such as the installation of a layer of sunnet above, is required to water every 2 to 3 days。
1. Timing of cultivation
Onions are given the option of planting in the spring and autumn of each year, during which the ambient temperature is stable between 15 and 20°c, and the climate is warm and humid, and the seeding of onions restores growth as soon as possible. Spring can take place before and after the festival of clarity each year, autumn can take place before and after autumn, and specific planting times need to be adjusted appropriately to local climatic conditions。
2. Selection of seed seed
In order for onion seed to flourish as soon as possible after seeding, clean seed full of particles must be selected for seedling. Before seeding, the plots need to be levelled, watered once, and onion seeds spread evenly into the soil, covering a layer of 1. 5 centimetres of thin soil, and water once, so that the seeds can grow better。
3. Replanting
When small onion seedlings grow to 40 to 50 centimetres, with a thickness of 1 to 1. 5 centimetres, the planting can be carried out from early june to early july, with a range of 70 to 80 centimetres during the planting period and a range of 5 to 6 centimetres, and once the planting has been completed, the growth of the plant will have to be accelerated by a wet, decompetent water。
4. Field management
In addition to the thinness and impatience of light during the period of onion seedlings, which can reduce the intensity of the filament light by building up a sunnet above, the soil around the plot needs to be relaxed regularly, watered every 2 to 3 days, and the thinly decomposition organic fertilized solution is pursued every 15 days, thus increasing the overall yield and quality of the plant。
