How are green onions grown, and how are green onions grown?

Green onions are two-year plants, and green onions are planted, and they generally need to be cultivated for three years. In the planting process, the seeds are sown in the autumn of the first year and the seedlings are overwintered; The next year it is transplanted in the summer and harvested in the early winter. If the seeds are to be harvested, the growing plants are stored in the open field or in the facility for winter, passed through the vernalization stage at a temperature of 2 5, and then transplanted to the open field in the spring of the third year, where moss and flowering are pulled under long sunlight, and the seeds are harvested on the summer solstice.

Due to the difference in climate between the north and south of China, the planting time of green onions can be planted according to local habits, and you can choose the planting time that suits you.

Green onions can be sown in autumn or spring. It is generally sown in spring and harvested at the end of October of that year. Mostly sowing, sowing date in early April, green onion seed germination temperature, to about 18 fastest.

Seedlings can emerge 5-6 days after sowing. Strong seedling standard: the seedling age is about 50 days, the seedling height is 30 cm, the false stem thickness is 1 cm, the leaf color is dark green, there are no diseases and pests, and the nutrient accumulation is more.

The planting time is generally in late May and early June. From mid-August to early October, the soil needs to be cultivated four times. Keep the false stems of the green onion straight every time you cultivate the soil. Clause.

When the first and second soil cultivation, the plant grows slowly, and the soil should be shallow; Clause.

When the soil is cultivated three or four times, the plant grows rapidly, and the soil should be thicker. Every time the soil is cultivated, the onion heart can not be buried, and the soil can be combined with supplementary fertilizer. To make the green onion white more than 30 cm long, it is necessary to bury the green onion stalk of more than 35 cm in the soil.

Promote the growth of green onions. At the end of October, it is generally ready to be harvested, and the harvest is harvested when the dew dries.

1. Choose bulbs.

For example, if you plant green onions in your yard, choose bulbs that are suitable for local planting habits and free of pests and diseases.

2. Planting beds.

1) Choose a well-drained plot that receives sunlight all day, dig it to a depth of 30cm, and add compost, blood meal or other organic matter to enrich the soil with nutrients.

2) Note: Before digging and fertilizing, make sure that the soil has been cleared of stones, branches and weeds.

3. Planting. 1) Plant the bulbs in the soil with the roots facing down, to a depth of 5 cm between the bulbs and 30 cm between each column, and water thoroughly.

2) When the soil temperature reaches 18-30, the seeds can germinate, and it takes about 1 month from planting to germination.

4. Seedlings. After the seedlings germinate, it should be decided whether to thin the seedlings according to the growth of the seedlings, and the spacing of the green onions after maturity is appropriate, and the weak seedlings should be pulled out in time.

5. Root protection. To prevent weeds from growing, grass clippings, pine needles, or bark can be used to cover the soil around the seedlings so that the soil is moist and even.

6. Watering. Throughout the growing season of green onions, water deeply every week to keep the soil moist.

7. Harvesting. Usually after 3-4 weeks of planting, the onions can be harvested when they grow to 15-20cm.

The time to grow green onions.

1. Spring planting: planting in early spring, watering once in the morning and evening, and nitrogen fertilizer should be sprinkled after watering to supplement nutrition.

2. Summer planting: usually planted in June and July, do a good job of shading measures, when the light is too strong, it will affect the yield of green onions, wait for the sun to go down every day, water 1 time, and apply diluted nitrogen fertilizer.

3. Autumn planting: planted around October, autumn belongs to the rainy season, the air humidity is high, so you can water once every 3 days, fertilize once a week, and do a good job of drainage before and after the rainy season to avoid rotten roots.

Answer: Green onions are biennials, but they are cultivated as triennials. Traditional cultivation method, sowing seeds in the autumn of the first year, overwintering with seedlings; The next year it is transplanted in the summer and harvested in the early winter. If the seeds are to be harvested, the growing plants are stored in the open field or in the facility for winter, passed through the vernalization stage at a temperature of 2 5, and then transplanted to the open field in the spring of the third year, where moss and flowering are pulled under long sunlight, and the seeds are harvested on the summer solstice.

Green onions can be sown in autumn or spring. The export of green onions, generally sown in spring, is harvested at the end of October of the same year, and is exported after finishing and packaging. The root of green onion is a string-like fibrous root, which is mainly distributed in the soil layer of 30 cm underground and 15-30 cm horizontally.

I think green onions are good and are an indispensable food for people's lives.

When planting green onions, it is necessary to plough the soil more than 30 cm and then apply basal fertilizer. 3. Planting: Sprinkle green onion seeds on the soil surface, and then cover with plastic film to keep warm.

4. Maintenance: Organic fertilizer should be applied 1-2 times during the growth period of green onions.

1. Planting time

The best planting time for green onions is in March to April in spring or September to October in autumn every year, because the temperature at this time can be stable at more than 10, and the humidity and light are more suitable, which is conducive to the rapid germination of green onions, but the specific planting time should be adjusted according to the local ecological environment.

2. Soil conditions

The root system of green onions is relatively delicate, suitable for growing in soft soil, when planting green onions, you need to choose sandy loam soil with good drainage, and then plough 30-35 cm of soil, remove the gravel and grass roots, and apply rotten organic fertilizer to the soil to promote the vigorous growth of green onions.

3. Planting method

When planting green onions, you need to choose full and round seeds without insect spots, and then mix the seeds with fine sand and a ratio of 1:3, and then spread them evenly on the soil surface, and cover a layer of plastic film to keep the green onions warm and moisturize, and wait for the green onions to emerge, you can cut the plastic film to expose the seedlings.

4. Maintenance management

Green onions like fertilizer, when breeding green onions, it is necessary to apply 1-2 times of rotten organic fertilizer during the peak growth period of the plant to provide the nutrients needed for its growth, and the green onions are not resistant to waterlogging, so it is necessary to dig a drainage ditch for the plant before the rainy season, so that the rainwater can flow out of the ditch quickly, and maintain the normal growth of green onions.

Green onions are a common seasonal vegetable, and they are inseparable from them in daily life. Green onion planting is very common, but some growers do not know much about the cultivation of green onions, so how to grow green onions?

1. Soil. Planting green onions does not have very high soil requirements, but the soil must be loose and have good air permeability, so that green onions can grow better.

2. Planting. The best season for planting green onions is spring, plant green onion seeds in a ditch on the sorted soil, the ditch is five centimeters deep, you can sprinkle the seeds in it, and then cover the soil, cover the soil layer with two centimeters, and then water and irrigate. When the soil is relatively wet and can enter the ground, it is necessary to use a rake to climb, and the soil is loose enough to be suitable for seed germination and growth.

3. Field management.

Observe the dead seedlings of green onions, and replenish the seedlings in time. Control the amount of watering at the seedling stage to avoid the growth of green onions. At the seedling stage of green onions, it is necessary to carry out two to three times of tillage and weeding to reduce weeds in the field, and at the same time, with proper tillage, can improve the moisture retention ability of the soil.

In terms of water and fertilizer management, there is no need for too much watering, watering is carried out according to the soil and seedling stage, and watering is carried out according to the principle of seeing dry and wet. In the growth stage of green onions, fertilization is carried out according to the growth of green onions, and about 5 kg of compound fertilizer can be applied each time, with watering.

1. Choose good breeds. There are many varieties of green onions, and good varieties should be selected before planting, and good varieties can be selected according to the local climate and personal preferences.

2. Soil preparation and fertilization. Before planting green onions, it is necessary to prepare the environment for planting. It is necessary to choose a soil with sufficient sunlight, close to water sources, easy to water, and rich in organic matter, and the right planting location can be conducive to the growth of green onions.

Before planting green onions, it is necessary to first prepare the land and fertilize, the land can be turned at least 30 centimeters deep, clean up the weeds and pests, break the soil clods, rake it flat, apply the rotten fertilizer, and then open a ditch according to the width of about one meter to one meter and five meters, and the ditch spacing is generally 80-100 cm.

3. Scientific planting. Sowing and planting: Green onions can be planted by sowing seeds.

Select the green onion seeds, dry the seeds in advance, and then use the medicine to dress the seeds. Tidy up the planting soil, you can use the method of hole sowing, dig a small hole in the soil, keep a good spacing, sow the seeds into the hole, about 2-3 cm deep, cover with thin soil, and pour in an appropriate amount of water. Bulb planting:

4. Post-management. After the green onion is planted and survived, it is necessary to pay attention to weeding the seedlings, irrigate regularly, pay attention to drainage, and apply fertilizer according to the growth.

First of all, find some green onion seeds, generally plant green onions to a certain time, it will bloom small white flowers, flowers withered will produce a lot of seeds, these seeds can be sown into the pot, it will emerge seedlings, just germinated green onions, is very fine, but there is no blind relationship, this time to keep the light sufficient, watering does not have to be too much, but can not be watered all the time, let it grow stronger.

At the same time, pay attention to making the soil more empty, fertile and loose. It will grow faster and the leaves will be thicker. To make the sown green onion grow fast, one is to have enough light, it is not afraid of the sun, and the other is to have fertile soil, it is best to use humus soil, pine needle soil, peat and the like, add a small amount of soil and river sand.

Finally, don't use too small and shallow flower pots, so that the green onion roots grow more developed and lush, and the green onion will grow well, so the small flower pot is replaced by a large flower pot, or a foam box, the soil layer is deep and fertile, and the green onion will grow quickly. In addition, the sown green onion seedlings, in order for it to grow faster and grow stronger, there is a trick, that is, to transplant it once, from small pots to large pots or flower beds, all grow very fast and count, one by one grows very big.

1. Buy green onion seeds

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, do a good job of shopping around, and don't be easily deceived.

2. Seed germination].

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 as follows:

Soak the seeds in warm water at about 40 for half an hour, then take out the seeds, wrap them in wet paper towels, and put them in a ventilated place for a few days.

This practice also has the advantage of screening out seeds that cannot survive and improving the overall survival rate of green onions.

3. Choose a flower pot].

Try to choose an open and breathable flower pot, you can choose a clay pot, but you must choose a relatively large flower pot, because the green onion planting occupies a relatively large area. Generally, there will be openings at the bottom of the pot to prevent water accumulation.

4. Make potting soil

Because the roots of green onions are relatively shallow and short, unlike many plants that can grow long root hairs, the absorption capacity of green onions for fertilizers is not strong, and they cannot accumulate water. Therefore, when choosing potting soil, it is necessary to choose fertile and loose and breathable soil, which can be peaty soil or nutrient soil. Although green onions are not very selective in the soil for planting in rural areas, the environment of potted plants is still much worse than that of rural fields, so it is still necessary to choose the right potting soil.

5. Potted sowing].

Dig a small pit every other distance in the potting soil, sprinkle 5 seeds in the pit, and then cover the seeds with soil, remember to cover the seeds as long as they are covered, not too thick, otherwise it will affect the further germination and growth of the green onion. If you are an experienced veteran, you can also sprinkle a handful of seeds directly and evenly, and cover a little thin soil.

6. Watering and fertilizing].

After the first sowing, the water should be watered thoroughly but not waterlogged, and there is generally no such problem if there are holes in the bottom of the pot. After that, it is generally about 5 days to water, and the number of watering should be adjusted according to the weather conditions and temperature. If the weather is dry and the temperature is high, water more appropriately, and if not, reduce the amount of watering.

Nitrogen fertilizer can be used for fertilization, and the amount of fertilizer applied each time is controlled according to the principle of "thin fertilizer and frequent application".
