When is the best time to raise green onions, and when are the best months for green onions to be see

1, the water needed by the onion, we all know, the green onion is a more drought-tolerant plant, planting the green onion to obtain a higher yield, but also need to pay attention to the coordination of water, different growth stages of the green onion, the requirements for water are slightly different, the general choice of planting green onion is dry seed sowing, green onion in the germination period needs high humidity of water, low water content in the soil, germination is not good, therefore, after the green onion is sown, it is necessary to keep the soil moist, so that the seeds can fully absorb the water.

After the green onion seedlings emerge, the water in the soil is sufficient, the growth of green onion seedlings is accelerated, this time is also the time when green onions are easy to grow, if the water is not controlled, green onion seedlings tend to grow thin and tall, not in line with the standards of strong seedlings, therefore, after the emergence of seedlings, into the seedling growth period, the water content should be properly controlled, the soil moisture content is kept at about 60%, the furrow surface is dry and wet, reduce the water of the **, properly maintain the drought, is conducive to the green onion to take root and produce strong seedlings. Green onions have the ability to withstand cold, and can be overwintered in the open field, and wintering water is indispensable before the onset of winter. Green onion after a winter baptism, the second spring, green onion needs enough water to grow, after the winter of the green onion to water again, can promote the growth of green onion, the spring temperature will gradually get higher and higher, green onion needs more and more water, should increase the amount of watering and the number of watering.

After the onion is planted, the appropriate water is needed to slow down the growth of the seedlings quickly, if the water is too large, it will cause the occurrence of onion rot disease, if the water is too small, unwilling to water, the green onion will return to the seedlings slowly, affecting the growth of the green onion, the best solution is to water the green onion, when the soil cracks out of the hoe and cultivate, so as to ensure the moisture in the soil, and provide good breathing to the root system of the green onion. The green onion planted in May and June, harvested in autumn and winter, should also pay attention to waterlogging prevention in the rainy season, after entering the autumn temperature, the growth of green onion is significantly accelerated, the formation of green onion white needs more water, at this time should pay attention to small water watering. 7 to 10 days before the harvest of green onions, if it is still watered, it is not good, it will cause green onions to be greedy for green and late ripening, and reduce the storage and transportation ability of green onions.

There are two methods of green onion seedling raising in spring sowing and autumn sowing and seedling, the first method is to start sowing in April in spring, and transplanting in early June after raising seedlings.

The second method is suitable for sowing seedlings around the autumn dew season, growing to a certain size of seedlings over winter, and continuing to grow in the spring of the next year, after the seedlings are mature, transplanting begins in early June.

Green onions are raised in September-October.

Green onions are most suitable for sowing seedlings in September and October in autumn, and under normal circumstances, they can grow to 8-10 cm tall or grow to 2 leaves and 1 heart before winter, which is conducive to smooth wintering. The sowing time is too early, the seedlings grow too fast before winter, and it is easy to pull out too early in the spring of the second year and affect the yield, the sowing time is too late, the seedlings grow weak before winter, the nutrient accumulated temperature is insufficient, and the trees are easy to freeze to death during winter.

Pay attention to the seedling management method:

1. After the green onion is sown in autumn, the seedlings can emerge in 8-10 days (the mulch film should be removed in time after the seedlings emerge), but before the seeds emerge to the cotyledons are not thorough, the watering must be controlled to prevent soil compaction; When the seedlings are about 2 cm tall after they emerge, they can be sprayed every 5-7 days to control pests and diseases.

When the seedling height grows to about 6-10 cm, it can be watered and topdressed with thin manure water or urea water according to the seedling potential, so as to promote the growth of the seedling as soon as possible.

2. Cultivate strong onion seedlings before winter, which is conducive to overwintering and growth after transplanting, and the standard of strong green onion seedlings before winter is: seedling height 8-10 cm, 2 leaves and 1 heart, and the diameter of the base of the seedling plant does not exceed cm.

3. When the seedlings grow to about 25 cm, you can transplant and plant the green onions, and the seedlings should be graded according to the size and thickness when transplanting, and the planting will be classified so as to facilitate the unified management in the later stage.
