Planting method and time of dried onion

The known planting methods of dried onion are mixed sand, compost soil, humus soil, etc. Put it in a flowerpot, add appropriate amount of bone meal and organic fertilizer as base fertilizer to improve fertility, and then bury two-thirds of onions in the soil. Water the soil before planting, and plant in March-May in spring and 9- 10 and 7- 15 days in autumn.

I. Potted soil

Prepare suitable soil and slightly larger flowerpots before planting. Onions are suitable for planting in loose, rich in organic matter, fertile soil and strong water retention. When preparing, sand, compost soil, humus soil, etc. can be added. Appropriate amount of bone meal and organic fertilizer can also be added as base fertilizer to improve fertility and promote onion growth. Just fill the soil into the prepared flowerpot.

Second, seed selection and planting

Buy ready-made onions, plant them in spring and autumn, spring in March-May and autumn in September-65438+10. Before planting, water the soil and bury the onions in the soil. Pay attention to the depth, not too deep The depth is about two-thirds of that of onions. The optimum temperature for onion germination is 13-20℃.

Third, fertilizer and water management.

Generally speaking, scallion has a shallow root system and is not drought-tolerant and waterlogging-tolerant. It is required to keep the soil moist, and the soil humidity is 70%-80%. Generally, water is poured once a week, and rice washing water can be poured every 10 day during the rapid growth period of onion to increase nutrition. When onion leaves are weak, chemical fertilizer can be sprayed, but nitrogen fertilizer is not suitable.

Fourth, light and temperature.

Onion doesn't have strict requirements on light, so it should be shaded properly in high temperature weather to avoid exposure, because too strong light will affect the taste, and it prefers to be cool rather than heat-resistant. The suitable temperature for growth is 18-20℃.

Verb (abbreviation for verb) harvest

It can be harvested about 1 month after planting. Unfinished plants can be planted in pots and harvested when necessary.

Variety selection

Be careful when choosing green onion seeds. There are many kinds of green onion seeds, some of which are white and sweet. There are also some green onions that taste very spicy. When planting scallion locally, we should choose high-yield scallion seeds according to the local market, local climate and soil conditions. Good varieties of green onions are generally green onions, which have good stability and, most importantly, strong cold resistance. Don't sow in a hurry after buying seeds. It is not difficult to accelerate the germination of seeds. Just soak them in cold water for half a day, then wrap them in wet cotton cloth, soak them in warm water for half an hour, and spray some water with a small watering can every day to keep the seeds moist for a week before sowing. ?

Seed sowing

Accelerate seed germination

Planting vegetables must be done first, and green onions are also suitable for sowing in flat places without exception. Because green onions consume a lot of water, it is necessary to consider whether it is convenient for irrigation at ordinary times when choosing sowing land, and then apply base fertilizer. 40 kg compound fertilizer should be applied to an acre of land as base fertilizer, which can help the green onion seeds to emerge in the later stage, and the seedlings need a lot of fertilizer in the early stage, so the base fertilizer is very important.

time

If green onions are directly sown with seeds, there are strict requirements on sowing time. It is generally best to sow before and after the Mid-Autumn Festival. If you sow at other times, it is easy to reduce the yield and strengthen the seedlings, especially if you sow it too late. In the cold weather in winter, seedlings are easy to freeze to death and frostbite.

Tiantuan management

After all the green onions are planted, it is similar to the steps of transplanting after everyone buys seedlings. After planting, they need to water it several times, once a week. Always pay attention to the weather forecast. When it rains, drainage and irrigation measures should be taken in advance in time. You can't let the roots of green onions soak in acid rain for too long, because the roots rot easily.

After autumn, we should pay attention to reducing the number of watering during the first frost, because water absorbs heat and the first frost itself will form a lot of water vapor. Attention should be paid to keep the roots of green onions warm and topdressing nitrogen fertilizer to protect the roots of green onions from frostbite. Welsh onion should be topdressing four times from emergence to vigorous stage, and cultivated after each fertilization, so that loose soil can promote root growth and the quality of Welsh onion can be guaranteed.
