When will onions be planted? How to manage in planting?

Onions are planted in autumn and spring. Onions avoid continuous cropping. When planted in autumn, they are mainly planted in fields with eggplant fruits, legumes, melons, and early autumn vegetables as the previous crops. If it is in the spring is mainly the use of winter idle plots, the latter is generally planting cucumbers, autumn cowpeas, autumn potatoes and other early autumn vegetables. Onions can be interplanted with other vegetables.

Generally speaking, onions are best sown in mid-September, no earlier than September 1 at the earliest and no later than October 15 at the latest. Those who are suitable for sowing are usually planted in the first and middle of November, no later than November 25 at the latest. At this time, the stem base of the seedling is 0.5 cm thick, the true leaves are 3-4, and the seedling age is 40-50 days. It can grow 3-4 new roots before the soil is frozen, which is beneficial to survive the winter safely.

Onions like to grow in a cool environment, because the climatic conditions are different in different regions, so the time of sowing onions is also different, usually concentrated in the first ten days of September every year. Planting method (1) select seeds to use onion seeds for planting, first select suitable seeds, choose good varieties according to your preferences, it is best to choose onion seeds in the same year, so the survival rate is higher.

Planting time and method of onion

The main results are as follows: 1. The planting method and time of onion are as follows: planting time: onion adapts to cold environment and has good freezing resistance, and the seedlings can grow even at the low temperature of-7 ℃. When the temperature exceeds 26 ℃, the onion will go into dormancy, and the leaves will die when the temperature exceeds 30 ℃. Therefore, onions are usually planted in autumn and cultivated in open fields in most areas in early September, and the planting time is arranged between mid-late October and early November.

2. The planting time of onions is mostly concentrated around early September, that is, when White Dew is in solar terms. At this time, the temperature and climatic conditions are the most suitable for the growth of onions, but also facilitate the follow-up management work. Although different varieties may have some differences, the overall time is about the same. The sowing method of sowing and sprouting onion is simple and can be sowed. In order to improve the budding rate before sowing, budding treatment is recommended.

3. Onion harvesting is usually carried out from the end of May to the first ten days of June. The time of harvest has a direct impact on yield and storage. When the onion leaves gradually yellowed from bottom to top, the pseudostem softened and began to lodge; the bulb stopped expanding, the skin hardened, and entered the dormant stage, which indicated that the bulb had matured and should be harvested in time. Onion seedlings should not be raised too early or too late.

4. Planting time and methods of onions (cultivation techniques and management) the planting time of onions is in autumn, usually around September-October, and the most suitable time is after the second half of September, because the weather in most areas turns cooler at this time. It is easier to sprout, if it is planted before this time, the temperature is relatively higher, the speed of germination will be slower.

How to grow onions

Onions can be directly seeded or transplanted. If it is planted in a large area, most of it is in the way of live broadcast. Sowing time should be early and not late. When the soil temperature of 10 cm soil layer is stable at 5 ℃, you can sow seeds.

Sow seeds at the right time. Onion sowing is generally before and after the Beginning of Autumn, the method can be strip sowing or sowing, requiring uniform sowing, the seed consumption is about 8-25 kg per hectare (according to the germination rate, according to the appropriate increase or decrease), each hectare seedling bed can be used for transplanting seedlings of about 15 hectares. Seedling management.

Planting time. Onions are planted around early September. When White Dew is in solar terms, the temperature is suitable, which is conducive to the rapid sprouting of onions. At the same time, the climate is more conducive to the growth of onions, easy to manage, generally planted by strip sowing or sowing. Accelerate the sprouting and sowing.

A simple method of growing onions

1. Onions can be planted by direct seeding or transplanting seedlings. Generally speaking, direct seeding is often used in large areas, and the sowing time should be sooner rather than later. When the soil temperature of 10 cm soil layer is stable at 5 ℃, you can sow seeds. Let's learn about the planting techniques of onions.

2. According to experience, onions are particularly easy to produce high yields in sandy loam, so when we plant onions, we try to choose sandy loam plots. If there is no way to choose, we also need to improve the soil quality by ploughing and applying bottom fertilizer to make the soil fertile, loose and ventilated.

3. Planting method: soil preparation: choose fertile, loose and well-drained soil. Before planting, loosen the soil deeply, remove weeds and stones, and apply an appropriate amount of organic fertilizer. Buy bulbs: choose healthy, pest-free onion bulbs. The size of the seed ball will affect the size of the mature onion, so you can choose different sizes according to your needs.
