Watering green onions in autumn is very important, how to water green onions in autumn?

Onion and garlic vegetables are a kind of fertilizer that requires more fertilizer and is fertilizer tolerant. It is very important to apply sufficient basal fertilizer, generally with organic fertilizer with phosphorus, potassium fertilizer or ternary compound fertilizer. The nutritional characteristics of allium and garlic vegetables are both potassium-loving crops and sulfur-loving crops.

Therefore, under the premise of balanced fertilization, we should pay attention to the application of potassium sulfate, and there is more rain in autumn, if the soil ditch must be cleaned up in time after heavy rain, to ensure that the roots of the onion will not be soaked. After the frost falls in the beginning of winter, the watering time needs to be extended to 12 to 16 days, because the temperature at this time is low and it is easy to freeze. There will be freezing after the winter solstice, and at this time, you can pour frozen water once!

<> temperature is on a downward trend, but it is still very high, at this time it is in the early stage of onion white growth, the plant growth is still relatively slow, the water requirement is not high, and less watering should be done. If watering is necessary, it should be watered early in the morning or evening to avoid watering at noon to reduce the ground temperature and affect root growth. This period requires watering 2 to 3 times, and if there is not enough rainfall, it needs to be watered manually.

The watering time during the growing of green onions varies greatly depending on the region and the weather. Generally speaking, the amount of watering of green onions is around 3-4 from planting to maturity, which is also closely related to rainfall. The combination of watering and fertilization at the same time is indispensable when watering after fertilization.

The amount of top dressing each time should be slightly more than the amount of the previous top dressing; When topdressing green onions, the fertilizer should be evenly sprinkled on the surface of the green onion roots, and then the soil should be covered with fertilizer to reduce the volatilization loss of fertilizer, promote the softening and elongation of green onion white, and enhance the wind resistance. Green onion fertilization needs to be watered once in two days, so that the fertilizer dissolves in the soil and quickly decomposes, after the white dew, the weather is cool day and night temperature difference increases, green onions enter the critical period of onion white formation, at this time is also a critical period of fertilizer and water management, in the white dew to the autumn equinox top dressing should be based on fast-acting nitrogen fertilizer, urea is good, about 20 kg per mu is appropriate, and 15 kg of potassium sulfate is added. The principle of "no drought and no watering", pay attention to timely drainage and flood prevention after rain, strengthen cultivation and moisture protection, and promote the development of root system.

Because green onions are very fond of moist growing environments, they should be watered every 1-2 days.

When watering in autumn, you must pay attention to the amount and keep the soil moist, because this time is the growth period of green onions, if you water too much, it is likely to lead to pests and diseases, you must be in moderation, and then there is too much rain in autumn, so you should also do a good job of drainage facilities to prevent rotten roots, and secondly, it is best to choose to water in the morning or evening, so as not to damage the foliage.

When watering in autumn, don't water too often, and water the soil thoroughly every time.

When watering in autumn, it should be watered thoroughly every time, and not too many times, so as to ensure the growth rate of green onions.

There is an inseparable relationship between the water characteristics of green onions and the growth stage. At the beginning of planting, the spring and autumn festival editions of the green onions grow fast, so the amount of water required is also large. During the vigorous growth period, water is required to be large, so watering is required.

When the shallots seedlings are cultivated, the density is large, the growth rate is also fast, the water demand is large, and the watering should not only be more, but also diligent. The combination of watering and fertilization at the same time is indispensable when watering after fertilization.

Autumn nursery period. From the time the seedlings are unearthed to the height of the seedlings is five centimeters, it is necessary to water two or three times in this process, once when the land is frozen, and once when the land is thawed the next year. From April to May, the temperature slowly rises, and the external environment is very suitable for the growth of green onions, in order to ensure that the green onion seedlings are strong, top dressing and watering should be carried out to promote the growth of seedlings.

Seedling and planting period in spring. The seedling period is short, in order to ensure the rapid growth of the seedling, fertilizer and water should be attacked, but the amount of watering and fertilizer should be determined according to the specific growth to prevent the onion seedling from growing and lodging. Fifteen days before planting, you need to control watering to refine seedlings, and then water the seedlings after planting, after the green onion seedlings are slowed down, it has entered the high temperature and rainy season, at this time, it is necessary to strictly control the watering and do a good job of drainage after the rain.

That is, the number of watering should be more, but the amount of watering should not be too much, and a small amount of water should be repeated many times.

This requires you to do your research, and it is best to consult those who are professional growers, who may have a lot of experience and can be very useful.

You have to consult those experts so that you can effectively prevent it.

In the whole growth period of green onions, when transplanting, the growth environment of green onions changes suddenly, the absorption capacity of the root system is temporarily weakened, sometimes in order to shorten the adaptation time to the soil, when transplanting green onions, you can decide whether to water according to the moisture, if the soil is relatively dry, you can water a thin water, but not large water, green onion white full period: at this time, although the growth of green onions slows down, but our growers and friends still have to pay attention to the dryness and humidity of the planting soil, to ensure the humidity of the field, In this way, the green onions can be tender and fat, and they can be sold at a good price. <>

Green onions can be planted in other seasons, except for those in winter when the temperature is low and cannot be sown. The growth period of green onions is relatively long, in order to ensure the quality and yield of green onions, seedlings are generally sown first, and when the green onion seedlings grow to about a month or so, they need to be transplanted, also called green onions. Green onions have different water requirements at different growth stages, and suitable soil moisture is required during the germination period to facilitate seed germination.

In the early stage of seedling growth, in order to prevent growth, it is necessary to properly control the water and keep the furrow surface dry and wet. Pour enough overwintering water before wintering, and water the green water after returning to green.

In the late stage of growth, it is mainly the stage of onion stem enrichment, which is the key period for the increase of green onion production. However, during this period, the upward growth rate of green onions began to slow down, and the water required by green onions at this stage was not much, so it was enough to keep the soil moist and meet the needs of onion stem enrichment. During this period, it is especially necessary to prevent and control the occurrence of diseases and pests of green onions.

Green onion planting watering is not the key, drainage is essential, green onion planting is to ridge planting, green onion longitudinal row to retain a distance between the green onions, convenient to give green onion root soil use, these have been to dig deep soil ditch.

It is recommended to water the seedlings twice during the two time periods of seedling raising and transplanting, and twice after transplanting and planting (provided that there are irrigation conditions), for a total of 4 times. So as for flood prevention, one is the choice of planting plots, it is recommended to have a certain small slope, not to choose a low-lying place, and the other is to cultivate the soil after planting, it is recommended that it is best twice.

After the frost to water the green onions, there are not too many restrictions, try to choose a small morning with better weather, if the local frost temperature is still far away, you can properly water the water, watering can keep the soil moist for a few more days, and it is good for the green onion false stem to be full.

Reduce the amount of water, it is best to choose a time when the sun is not very sufficient, so that it is very beneficial for green onions.

In the later stage, you don't need to water so often, you can water once in 5 or 6 days.

1. At first, once a day in the morning. After that, wait for the soil to dry out and water it once.

The leaves are cylindrical and hollow, and its leaf sheath stems contain false stems, which will cause stick-like "green onions" if the soil is softened. Green onion white is the main edible part.

On November 15, the certification officer of the World Guinness Headquarters measured a green onion in Zhangqiu on the spot, with a length of meters, creating a new world Guinness green onion height record.

Dear, I'm glad to answer for you: Can green onions be watered after the beginning of autumn Answer: Hello kiss Green onions can be watered after the beginning of autumn Oh After the beginning of autumn, with the drop in temperature, the growth rate of green onions accelerates, and the demand for water increases, so we should pay attention to timely watering.

However, sometimes the temperature is still very high after the beginning of autumn, and it often rains heavily, and sometimes it will be rainy and rainy, and the green onions do not need a lot of water. Therefore, after the beginning of autumn, it is necessary to water appropriately according to the weather to promote normal growth. If my answer was helpful, please give <> like
