Green onions like cold and are afraid of heat, can they be planted in a large area in the south?

Green onions are generally not suitable for cultivation in the south. The main factor is that the climate and soil are quite different. Southern region.

The climate in winter is still relatively warm. After planting green onions, there is a high chance that slow buds or long leaves will occur. The best temperature for the growth of green onion leaves is 15 25, and when the green onion is 10 20, it is the time when the green onion white grows the most vigorously.

If it is more than 25, the growth will become slower, and the quality of the leaves and stems will decrease, so if you grow green onions in the south, you can choose the plastic greenhouse variety!

We are here in Zhanjiang, and we have never seen green onions since we were children. There could be several reasons for this! Most of us eat green onions and eat green onions.

Many places come to us to buy. Green onions may not be planted here, they may not be planted well, or they may not have the habit of eating green onions. The following pictures are the green onion streams that we often grow in Zhanjiang.

Southern green onions can be planted in three seasons every year: spring, summer and autumn. Before planting, the soil should be loosened to improve the porosity of the soil, and then the row spacing should be dug out of a shallow trench of 20 meters, the end of the sowing should be covered upwards, covered with fine soil, and the sowing will germinate after 2 weeks. Sowing seeds in early September in the autumn of the first year, seedlings for winter, planting in early to mid-May in the summer of the second year, harvesting before winter, cellaring for winter, flowering in the spring of the third year, harvesting seeds in the summer season, seedlings at the time of planting can be marketed as shallots from early May to late June.

Sow seeds after the soil thaws in early spring, with shallots** before the scorching heat, or with shallots or shallots** harvested in the same year after the main meal. Moon caves can also be used as a pie pie or as a species. Most of them are sown from late July to early August, so they are also called raspberries, and the plants in Woldong City were relatively large that year.

It is easy to complete the vernalization process, and the early buds of Yichun bloom quickly, and they are usually listed after the sheep's horn.

There are many varieties of green onions, and green onions are very practical for the environment and can be grown basically anywhere, but it is only a matter of yield and quality, so choose varieties that are suitable for the local climate before planting. First of all, you can investigate the varieties that are suitable for local green onion cultivation. You can choose high-quality, high-yield, market-leading varieties for planting, and then you can plant a variety of varieties to obtain the economic benefits of planting and enhance the effect of appetite

Green onions can promote the secretion of gastric juice and digestive juices, help strengthen the body's digestive function, enhance appetite, **indigestion.

Symptoms such as loss of appetite. 2.Anti-cancer effect: Green onions contain fruit acids.

and garlic, which can inhibit the growth and spread of cancer cells, and effectively prevent esophageal cancer, stomach cancer, and colon cancer.

and other cancers. 3.Cholesterol-lowering effect: Green onions have the effect of reducing the amount of cholesterol in the serum and preventing hyperlipidemia.

and other symptoms are effective.

No. Because the weather in the south is particularly hot, the south is not suitable for growing green onions.

Green onions can be grown in the south. Green onions are native to China and are mostly found in northern China and less commonly in the south. Green onion is a variant of green onion, which is different from the green onion (shallot) variant and the red onion (building onion) variety, the shape of the aboveground part of the green onion plant is more like an onion, and the leaves are cylindrical and hollow.

No. Although green onions can be planted in the south, if you want to plant green onions in a large area, I am afraid that it will cost a lot of manpower, material resources and financial resources, so it is difficult to plant green onions in a large area in the south.

Yes, the weather in the south is quite suitable for the growth of green onions, and you can also plant a large area here.

It can be planted on a large scale, and in the south it grows at an astonishing rate, and it can be sold in a short period of time.

Personally, I don't think it's good, but it's best to plant it in a suitable place.

Of course, green onions are grown in many places in the north, and Shandong is the most famous green onion production area.

No problem, it has a wide range of adaptation, and it is a relatively easy to grow cash crop. The output can reach up to more than 10,000 catties, which is the highest instability. It's hard to fathom.

Hello, onions can be grown in greenhouses. Onion greenhouse cultivation: Onion is a cold-tolerant vegetable with a long growth period and requires long days and high temperatures.

The seedling age is about 50 days, the seedling height is 20 25 cm, 4 5 leaves, the stem thickness is cm, the root system is developed, and there are no diseases and pests. Under normal circumstances, the greenhouse is sown and raised seedlings in late March. 

The time when green onions were planted in the northGreen onions are widely planted in the north and south of our country, and most of the green onions in the north are planted in autumn. When planting green onions in the north, they will choose to sow in early September in autumn, and the green onion seedlings need to be reasonably maintained for the winter, and then planted in May and June of the following summer, and harvested before the winter arrives.

Green onions should be disinfected before planting, the depth of planting is controlled at about 2 5 cm, and it should be reasonably watered after planting, and placed in a cool place for maintenance. However, it should be noted that it should not be placed in a cool place just after watering, otherwise the seeds are prone to mold and are not conducive to growth.

When planting green onions in the north, you should choose nutrient-rich, fertile, and well-drained soil for planting. When planting, it is necessary to maintain a suitable row spacing and plant spacing, generally speaking, the row spacing is about 70 cm, and the plant spacing is about 5 8 cm is the most suitable.

The planting time of green onions in the north is to start planting green onion seedlings in mid-April, and to start cultivating green onions in July.

Northern green onions are generally sown in early September in the autumn of the first year, overwintered with seedlings, planted in May and June in the summer of the second year, harvested before winter, and overwintered in the cellar or open field. Green onions should be planted in loam soil plots with rich organic matter content, deep soil layer, high and dry terrain and convenient drainage, with a row spacing of 70 cm and a plant spacing of 5-8 cm, and watering should be stopped 7-8 days before harvest to improve the storability of winter storage green onions.

Hello, the northern green onion planting time, the northern green onion is sown in autumn in September, the winter green onion seedlings are reasonably maintained for the winter, the green onion is planted in May of the next year, and the green onion is harvested in October.

1.Large shallots can be grown in the south, but compared to the northern regions, the northern regions are more suitable for growing large shallots. There are more rainy seasons in the south and the temperature is high, but the large onion likes a cool growth environment, so the south has some shortcomings in planting the large onion, and the flowering period of the southern planting of the large onion is not as long as the planting in the northern region, and even in the second year, there may be no flowering, but with the development of technology in our country, there are many solutions now, such as greenhouse planting, greenhouse planting and so on.

2.Shallots used to belong to the group of flowers, but later they were classified as allium plants. Although it belongs to the onion family, it is not used for eating, but is a common ornamental plant, and gardeners and florists prefer to use large onions to decorate gardens, flower beds or courtyards.

If you want to grow shallots in the open field, you should choose loose and fertile sandy soil, because in such an environment, shallots grow better.

3.When selecting seeds, it is necessary to choose large onion seeds with full and shiny grains, because such seeds are of better quality. Generally, the seeds are sown from September to October every year, and if the flower grower carefully manages them, they can sprout in March of the following year, and the flowers that grow look like a hydrangea from a distance, which is very beautiful.

The differences between the north and the south, the temperature difference, and the soil are all related, and look at the external environmental impacts you need to make up for the needs of planting

Green onions, Lycoris allium is a biennial herbaceous plant, there are more than 100 kinds of Chinese allium vegetables, mainly distributed in the northwest, northeast and north China. So when is the best time to plant and harvest green onions in the north? How much is a pound of green onions in 2018?

When is the best time to sow green onions? When is the green onion planting?

There are generally two traditional planting methods of green onions in the north: seedlings in late autumn, planting in May and June of the following year or seedlings in early spring. The harvest season of both methods is generally July and October, and the market is postponed to the Spring Festival after storage.

Heze High-tech Agricultural Science Research Institute, using the characteristics of green onion with strong cold resistance, explored and cultivated a new variety of Hanfeng green onion and a set of new methods of off-season cultivation in the open field, so that fresh green onions were listed in the off-season in February and June, and the economic benefits increased exponentially.

Its planting to harvest in the north is generally from September to April of the following year, which is the winter leisure time of the land, and it does not affect the planting of other crops after harvesting Hanfeng green onions.

Growing green onions in the north takes about two seasons:

1. Sow seeds in the spring, and at the beginning of summer, you can eat them.

shallots". In the fall, leave it alone. In the second year, the spring is green, that is, "sheep's horn onion", waiting for flowering and fruiting.

2, is in. White dew".

Before and after the solar term. Soon after the germination, it snowed heavily, so leave it alone. In the spring of the second year, the green onions return to green, grow to more than a foot long, get out of the ground, replant, and in autumn, they are long green onions, which can be stored in winter.

Spring planting of green onions is the use of autumn onion seedlings transplanting. The suitable temperature for the germination of green onion seeds is 15 25, and it can germinate in two or three days after the seedlings are raised. Green onions are resistant to low temperatures, can withstand the low temperature environment of minus 20, so the frozen green onions, North China is the main production area of green onions, green onion sowing is divided into spring sowing and autumn sowing, mainly autumn sowing, generally in mid-September to early October sowing in the second year of transplanting, sowing too early, green onion seedlings are easy to sprout, sowing too late, green onion seedlings are too small, can not overwinter.

<> autumn sowing seedlings and summer transplanting, in order to harvest the high onion white in autumn, the whole growth period reaches more than a year, so it is necessary to select excellent varieties with strong resistance, strong adaptability in the local area, and strong commerciality for sowing. Such as tall white, Zhangqiu green onion and other varieties. The unshaven green onions are kept for the winter, and the sprouts in spring are the horn onions"The more you eat the scallop sauce, the fatter you get.

The scallion is kept until the Qingming Dynasty to grow the green onion mother, the green onion mother bears seeds after flowering, and the onion seeds are harvested after the beginning of summer and sown in the autumn.

Green onion seeding. Around September, the green onion field is flattened, and the farmhouse fertilizer is applied, 200 quintals per mu, and 100 catties of compound fertilizer are added as base fertilizer. When sowing, the green onion seeds should be soaked in water for 6 to 8 hours before sowing.

In this way, the green onions emerge from the seedlings and the seedlings emerge quickly. , water and fertilizer absorption capacity is not strong, neither drought tolerance, nor waterlogging tolerance, so if you want green onion seedlings to be strong, you should choose fertile and deep soil, loose and permeable soil, sunny and close to water, convenient drainage and irrigation land, it is best to be conducive to the drainage conditions of good light sandy soil.

The requirements of green onions on the land are suitable for drought and not waterlogging, the requirements for soil quality are more suitable for neutral soil, and the sowing time is best to start sowing after the summer heat in the 24 solar terms, and the best time for the shallot to reach complete seedlings before the white dew. Picking green onions is still a technical job, it is easy to see, but without experience, it is very easy to break the green onions, so it is good to be careful during harvesting or need to be careful. It is best to avoid harvesting in the morning or when the temperature is low to avoid freezing after the green onion is harvested.

It is best planted in late autumn. Because this temperature is just right for the growth of green onions, this time can also increase the yield of green onions, so that green onions grow more tender.

It is better to plant in spring, because planting at this time will make the green onions take root and sprout quickly, and the probability of death is very small.

It is better to weigh in spring, because the climate in spring is more suitable for the growth of green onions.

Green onions are best planted in autumn, and they will grow well if planted in autumn, so most people plant green onions in autumn and winter.

The best planting season for green onions is in autumn, while the green onions in the Yangtze River basin are generally sown in March and April and harvested in June and July. It is also possible to sow in 9 October and harvest in 4 May of the following year. During this period, the young seedlings that have not grown up are mainly eaten in the market.

The planting environment must be shady, and the garden with loose soil should be selected; Yes, but the yield may not be very high.

In the process of planting green onions, attention should be paid to ridge planting. In this way, the onion can be whitened for a longer period of time and the yield can be increased. The land in the south can also be grown with green onions. But scientific management is needed.

When planting green onions, you should choose humus soil, you should often cultivate soil, you can often sheep manure or farm fertilizer, when planting green onions, you should keep a distance, not too close so that you can achieve high yields. It is possible to grow green onions in the south, but because there is more rain in the south, it is difficult to achieve high yields.
