How shallots are grown, how shallots are grown

It's best to plant green onions in July! As the saying goes, "July onion and August garlic" Third, planting Green onion planting is generally in the period from (early June) to small summer (early July). When the onion seedlings grow to a height of 30-40 cm and a transverse diameter of 1-cm, it is suitable for transplantation.

Before transplanting, the seedbed infiltrates water 1-2 times, and the seedlings should be selected and graded when the seedlings are raised. Remove dead leaves, remove seedlings with diseases and insects, select stout, non-forked seedlings, and plant them separately according to the size of the seedlings, planting density, generally row spacing of 100-120 cm, plant spacing cm. Tens of thousands of seedlings.

The depth of the planting should be exposed. 4. Field management After planting, the physiological function of the aboveground part and root system is weakened and the growth is slow. At this time, if it is not too dry, it is not advisable to water more.

Drain water after rain to prevent waterlogging to avoid root rot, yellow leaves and dead seedlings. It should be cultivated, loosened and weed many times to promote root development. Autumn is the peak growth period of green onion leaves and green onions, and it is necessary to water, top dressing, and soil cultivation in time to promote the rapid growth of green onions.

Watering should be diligent, always keep the soil moist in the onion field, and stop watering 1 week before harvest. In order to grow and soften the green onion, top dressing and soil cultivation should be carried out 3-4 times from August to September. Top dressing is mainly nitrogen fertilizer, and superphosphate and plant ash are appropriately added, generally applied once every 15 days or so.

Each mu is applied 10-15 kg of urea and 15 kg of superphosphate. Soil cultivation should be carried out in the morning after the dew is dry, but the soil is still cool, and the soil should be cultivated once every half month. Finally, it is cultivated into a high ridge, and each time the soil is cultivated to the degree of not burying the heart leaves of the green onion.

Prepare the seedbed: apply plantar fertilizer to the seedbed, then plough and rake to make a 1 meter wide flat furrow. Sowing at the right time:

Spread the green onion seeds on the furrow surface at a row spacing of 15-20 cm and cover with soil. Post-sowing management: water a small water once after the seedlings are gathered, and water the frozen water before winter.

Precautions: Top dressing should be done 3 times during the growth period of green onions, mainly urea.

1. Prepare the seedbed

When planting green onions, you should choose a plot with fertile soil, irrigation and drainage, and no onions and garlic vegetables that have been planted within 3-4 years, and then plough more than 15 cm deeply, and then sprinkle 2500 kg of rotted farmhouse fertilizer per mu of seedbed, and then deep plough and rake once to make a 1-meter-wide flat furrow.

2. Sow seeds at the right time

Green onions like cool climate, mainly spring sowing and autumn sowing, as long as the temperature reaches more than 7 degrees Celsius, the most suitable sowing temperature is Celsius, the green onion seeds are sown on the furrow surface according to 15-20 cm row spacing, and then covered with fine soil and mulch film to maintain warm germination conditions.

3. Post-broadcast management

Green onion should pay attention to moisturizing after autumn sowing, and so on after the seedlings are unearthed, the mulch film will be unveiled in time to prevent the seedlings from burning, when the green onion seedlings are watered once a small water, and before the winter watering frozen water, and then sprinkle a layer of horse manure on the seedlings, Duan Pai soil miscellaneous fertilizer, in order to help prevent cold and keep warm, and promote the seedlings to overwinter.

4. Precautions

Onions need to be topdressed 3 times in the growth period, the first time in early August after the seedlings, 5-10 kg of urea per mu, the second time in late August, the third time in early September, top dressing should be carried out at the same time as the soil, in order to promote the absorption of fertilizer by the root system and prevent the lodging of green onion seedlings.

The method of planting green onions starts with planting time, soil preparation, purchase and sowing, sowing, and maintenance management.

1. Planting time.

Green onions like a cool growth environment, relatively cold-resistant, in general, green onions are mostly spring sowing and autumn sowing, the southern region is mostly spring sowing, the northern region is mostly autumn travel sowing mainly, as long as the temperature reaches 7 with the town of Xin's Zhilun degree or more can be sown and planted.

2. Organize the soil.

Planting seedlings to choose the right soil, can be good drainage, strong permeability, loose soil, fertile soil, can not choose compacted soil, or it is difficult to ensure good growth. Before planting, it is necessary to do a good job of ploughing, apply enough fertilizer to ensure good nutrition, and water in time to keep the soil moist.

3. Buy seeds.

There are many varieties of green onions, so you should choose a good variety according to the actual situation and your own preferences, go to the seed store to buy good seeds, or you can collect seeds and store them yourself in summer.

Fourth, carry out sowing.

Sow the seeds on moist soil, cover with a thin soil of about 1 cm, gently press the soil, and then cover with plastic film to keep the temperature warm and moisturized.

5. Maintenance management.

The growth of green onions requires a certain amount of light, so after sowing, sunlight cannot be missing, to ensure the right amount of sunlight, can not be raised under strong light. When the green onion grows tall, it is necessary to ensure that the water is sufficient, timely watering and irrigation, and also pay attention to fertilization to ensure good nutrients.

Plant green onions deeply, plant garlic shallowly, and dig deep ditches and cultivate more soil if you want green onions to grow.

The seeds of green onions are very small and very light, which means that the seeds of green onions originally contain not much nutrients, so we must be more careful about the seeds of green onions, otherwise the potted plants are likely to not be able to survive. When purchasing, we have to select new varieties within one year, so that the germination ability is relatively strong, and the germination rate can reach more than 90%. If the seed is more than 2 years old, the germination rate will drop to less than 30%, and it is very difficult to feed.

It is recommended to go directly to the countryside to find some seeds to plant, which are usually new seeds of the year. If you buy online, it depends on the credibility of the store and user evaluation, and Qiaoji does a good job of shopping around, so as not to be easily deceived.

Tips for planting shallots

Because the germination ability of green onion seeds is relatively weak, it is not recommended to sow the seeds directly into the soil and leave them to fend for themselves. We can treat the seed first to help it germinate.

Soak the seeds in warm water at about 40 degrees for half an hour, then remove the seeds, wrap them in a damp paper towel, and leave them in a ventilated place for a few days. When the seeds have grown small shoots, the pretreatment of the seeds is completed. Another advantage of this practice is that it can screen out the seeds that cannot survive, and improve and eliminate the overall survival rate of the onions.

1. Land selection.

The root group of green onions is small, no root hairs, and poor fertilizer absorption ability, so it is necessary to choose the following in the soil: 1) loose soil; 2) deep soil layer; 3) fertile soil; 4) Good drainage; 5) soils rich in organic matter; pH: 6—

Second, soaking seeds to promote germination.

In order to ensure the germination rate of seeds, seeds should be soaked and germinated before sowing. Soak the planting in cold water for 8-10 minutes, wrap it in a wet towel after taking it out, place it in a warm water environment of 15-20 degrees, open it and rinse it with water once a day, and sow it when the radicle is exposed.

3. Sowing seeds and raising seedlings.

The seedling time of green onions is generally from September to October. Sowing too early will lead to too many seedlings before winter, and it is easy to sprout in the following spring; If the seeds are sown too late, the seedlings are weak in winter and easy to freeze to death during overwintering. In order to grow the seedlings neatly, the method of strip sowing is generally adopted.

According to the row spacing of 10-15cm, open a shallow ditch, sow after watering, and use 350-400g of seeds per mu

Fourth, seedling management.

From sowing to emergence, it should be watered frequently, keep the soil in the field moist, and avoid soil compaction, which will lead to difficulties in the emergence of seedlings, and water again after the seedlings are unearthed. When watering, the amount of water should be controlled, and it should not be too much, which will cause the seedlings to grow.

5. Planting time.

In winter, the planting time of green onions is generally between November and December. According to the row spacing of 80cm, the plant spacing is, and the ditch is planted.

6. Field management.

Fine management in the field is a good way to achieve high yields. Generally, from planting to harvesting, 5-7 times of soil cultivation should be carried out, and the height of the soil should not be buried in the heart leaves, and the soil cultivation is conducive to increasing the length and quality of green onions; Each soil cultivation can be accompanied by fertilizer and water.

Choose the type of green onion you want to plant, find the seeds, choose a well-drained area with all-day sunshine, dig to a depth of 30 cm, add compost or other organic matter.

About four weeks before the last frost, the seeds or bulbs can be planted, in the case of seeds, the depth of the seeds is cm, the distance between the columns is about 30 cm, in the case of bulbs, the roots are planted, the distance between each other is 5 cm, the depth is cm, and the columns are 30 cm apart.

After ripening, the spacing of green onions should be centimeters, and the seedlings should be covered with grass clippings or bark on the soil around the seedlings.

If you plant shallots in pots, you can skip this step and water the shallots about a centimeter deep every week throughout the growing season, and after 3-4 weeks, the shallots will grow to 15-20 cm, at which point they are ready to eat.
