How many degrees below zero will green vegetables freeze? Small greens will freeze to death at minus

Different vegetables have different freezing points, such as Chinese cabbage is a semi-cold-tolerant vegetable, which is not resistant to high temperature and cold, and will freeze if it is minus 4 degrees for too long. The average temperature most suitable for the growth of Chinese cabbage is 17, and the temperature above 25 or below 10 will cause poor growth, and stop growing below 5. In winter, the use of Bikagen can raise the ground temperature and prevent frost damage.

It depends on how you define bad, if it means rotten and inedible, then it is absolute zero.

It's fine, if it refers to irreversible deterioration, it is about -50, and those with a lot of moisture, such as radish, etc., will have a higher temperature, around -10, because the water will expand and squeeze out the cells, if vacuum freeze-drying is used.

method, then without the influence of water, the temperature can be lower, below -100.

The physiological needs of different vegetables are different, and they should be analyzed on a case-by-case basis.

The suitable storage temperature for cabbage, celery, onions, carrots, etc. is about 0.

Cucumbers, eggplants, tomatoes, etc., should be stored at a temperature between 7 2 and 10.

Pumpkins should be stored above 10 °C.

Tomatoes After the tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there is a phenomenon of spallation, there are black spots on the surface, undercooked, no umami, and in serious cases, it is rotten.

If the banana is stored in a place below 12, it will make the banana black and rotten.

If the fresh lychee is left in a 0 environment for one day, the skin will turn black and the flesh will become flavorful.

0 will freeze down, the water in the cell will freeze into ice, destroying the intracellular structure, generally the upper layer can be refrigerated.

Hello, from 7 degrees to minus 5 degrees, Chinese cabbage will not be frozenCabbage is relatively cold-tolerant, can withstand the low temperature of about minus 8, and will be frozen if the temperature continues to drop to about minus 11.

1. The growth temperature of Chinese cabbage

1. Minimum growth temperature.

Under normal circumstances, Chinese cabbage can withstand low temperatures of about minus 8, and if the temperature continues to drop to about minus 11, it will be frozen.

2. Suitable temperature.

Chinese cabbage is a semi-hardy vegetable, prefers mild and cool climates, usually the seeds germinate at 8-10 hours, germinate quickly and robustly at 20-25 hours, and the suitable temperature during growth is 10-22.

Temperatures above 25°C will cause poor growth, and temperatures above 30°C will not grow.

2. Precautions for planting Chinese cabbage

1. Cabbage is relatively hardy and likes a cold climate, so it is suitable for growing in the cold season. If cabbage is cultivated in the hot season, it is prone to diseases and pests, resulting in poor quality and reduced yields, so cabbage is not suitable for summer planting.

2. Cabbage has strong resistance to low temperatures. When the temperature reaches minus 3, if the temperature can gradually rise, the cabbage can also resume growth. If the temperature drops to minus 11 at minus 8, the cabbage will not regain its growth, but will suffer from frost damage.

3. Maintenance of Chinese cabbage

1. Soil. Planting cabbage has high requirements for soil fertility, if the soil is not fertile enough, you can choose to use sea meal fertile water-soluble fertilizer topdressing, requiring the soil to have high humidity, suitable for planting in fertile soil, better drainage soil.

2. Illumination. Cabbage is more light-loving and suitable for planting in a place with enough light. Lack of light will seriously affect the yield of cabbage, and certain protective measures should be taken in summer to avoid burns.

3. Moisture. Raising cabbage should be watered more, in the growing period need to keep the soil moist, it is best to do not accumulate water on the surface, but there is no shortage of water, sufficient water is the reason to ensure its high yield.

7 degrees to minus 5 degrees, can Chinese cabbage freeze in the hole, Chinese cabbage is generally relatively cold-resistant, it will not freeze at about 0 degrees to minus 5 degrees, he can thaw when it is warm.

Answer hello, Chinese cabbage will not freeze at minus five degrees, cabbage likes to be cold, and it is a semi-cold-resistant vegetable. Although it is not very cold-tolerant, it can only be frostbitten at minus 5 degrees Celsius, and will not freeze to death. When the temperature drops, Chinese cabbage will try to increase the concentration of cell fluid in order to prevent frostbite of its own cells.

Cabbage is native to northern China and is a leafy vegetable of the Brassica genus in the cruciferous family, usually referring to Chinese cabbage. It is introduced to the south and cultivated in all parts of the north and south. In the 19th century, it was introduced to Japan, Europe and the United States.

There are many kinds of Chinese cabbage, and the northern Chinese cabbage includes Shandong Jiaozhou Chinese cabbage, Beijing Qingbai, Tianjin green hemp leaf Chinese cabbage, Northeast dwarf Chinese cabbage, Shanxi Yangcheng big burrs, etc.

From a physical point of view, 7 degrees Celsius is a degree to minus 5 degrees Celsius, and Chinese cabbage will freeze in the ground.

Because below 0, there will be frozen vegetables.

Seven degrees to minus five degrees Chinese cabbage is bad in the ground, seven degrees to minus five degrees, Chinese cabbage is 7 degrees to minus 5 degrees on the ground, can Chinese cabbage be bad in the ground? From 7 degrees to minus 5 degrees, Chinese cabbage cannot be frozen in the ground.

Can Chinese cabbage freeze when pulled back at minus 7 degrees Celsius and put it in the yard.

Small greens will freeze to death at 4 degrees Celsius, and the most cold-tolerant varieties will also freeze to death at -8 degrees Celsius, and the leaves will become transparent and rot after frostbite.

Small greens are a relatively hardy leafy vegetable.

The suitable growth temperature is 15 23 °C, and there is very little frost damage when encountering a short period of low temperature. Southern region.

It can be planted all year round, and it is planted more in spring and autumn in the cold regions of the north, and when the temperature is particularly low, it needs to be planted in greenhouses.

Precautions for planting small greens:

Soil: Deep, loose and breathable soil is needed to grow young greens.

Light: It loves light, so you can keep it on the balcony or outdoors in a well-lit place.

Temperature: It likes warmth, the most suitable growing temperature is 15-23, not less than 4 in winter.

Watering: It is not drought tolerant and needs a lot of water during growth. It should be poured as soon as it is dry, and the soil should not be allowed to dry out.

Fertilization: It is more fertilizing and requires top-dressing nitrogen fertilizer during growth.

Small greens will freeze to death at minus 5.

The most suitable growing temperature is between 18-20, and the cold resistance of small greens is very strong, and it can safely survive the whole winter at low temperatures 2 3. But below that, it can freeze to death. If the temperature is around 5, the growth rate of baby greens will become slower, and sometimes there will be a pause in growth.

Maintenance of small greens in winter

1. Soil. The root system of small greens is relatively developed, and it is suitable for growing in deep soil. It grows better in loose, fertile, well-drained, neutral or weakly acidic sandy soils.

2. Illumination. It loves sunlight and grows more vigorously in sunny places. It is recommended to place it on a balcony or outdoors in a sunny and well-drained place for maintenance, which will be more conducive to its growth.

In summer, when the sun is strong, proper shading can be applied to avoid wilting the leaves.

3. Fertilization. It is more fertilizing, especially the need for nitrogen fertilizer. During the growth period, it is necessary to supplement enough nutrients, be sure to apply foot fertilizer, and apply fertilizer twice during the period, which can appropriately supplement some fertilizers containing phosphorus and potassium.

Top dressing should be combined with irrigation to keep the soil moist at all times.

Cabbage will freeze at minus 11 degrees Celsius.

It is very resistant to low picosporous temperatures. After the temperature reaches -3, if the temperature can gradually rise, it can resume growth, but if it reaches -8, the temperature continues to drop to about -11, it cannot resume normal growth and suffers from frost damage.

The minimum temperature of Chinese cabbage storage is 0. Generally, the indoor temperature is above 0 degrees, and the Chinese cabbage will not freeze. The minimum temperature for storing Chinese cabbage is not lower than minus 5 degrees, and the optimal temperature for storing white cabbage is generally 0 5.

How to save:

There are many ways to preserve Chinese cabbage, if you want to preserve Chinese cabbage in a short period of time, then you can choose to put it in a ventilated place for preservation, and generally this way can be stored for two or three days without any problems.

After removing the dirty matter of the Chinese cabbage, spray some water, then put it in a ventilated place indoors to keep the air circulating, and then spray some water on the body of the Chinese cabbage regularly to ensure that it is moisturized. As long as sufficient moisture can be maintained, the Chinese cabbage will not deteriorate in a short time. This method is suitable for storing Chinese cabbage for a short period of time.

Cabbage is generally exposed to frost damage at temperatures ranging from -8°C to -11°C.

Cabbage is hardy and prefers a cool climate, so it is suitable for growing in the cold season. If it is cultivated in the high temperature season, it is prone to diseases and insects, or the quality is inferior and the yield is low, so it is not suitable for summer cultivation. It is very resistant to hail and local temperatures from low sources.

After the temperature reaches -3, if the temperature can gradually rise, the cabbage can resume growth, but if it reaches -8, the temperature continues to drop to about -11, it cannot resume normal growth and suffers from frost damage. Cabbage is suitable for planting in loam, sandy loam and black loess that retain fertilizer and water and is rich in organic matter, not suitable for planting in sandy soil that is easy to leak water and feces, and not suitable for planting in clay soil with poor drainage.

Chinese cabbage minus 4 degrees will not be frozen, cabbage is more cold-resistant, after the temperature reaches -3, if it can gradually bring the temperature up, it can also resume growth, but if it reaches -8, the temperature continues to drop to about -11, it can not resume normal growth and suffer from frost damage.

Chinese cabbage cultivation method.

1. Soil preparation and fertilization.

Before planting Chinese cabbage, it is necessary to prepare the land and fertilize it in advance to ensure a good planting environment. Plough the soil about a week before sowing to remove the residues of previous crops in the soil, clean the field, and plough the soil. In addition to land preparation, it is also necessary to apply fertilizer reasonably, in general, about 5,000 kg of rotting organic fertilizer is used per mu, with the use of ternary compound fertilizer.

Around 60 kg.

2. Carry out sowing.

Sow seeds in a timely manner after dressing with new high-fat film, you can choose strip sowing or hole sowing, the amount of seeds per mu is about 150-250 grams, and the topsoil is lightly raked with a tooth rake to sow the seeds into the soil.

3. Seedling management.

After the seeds germinate and emerge, the seedlings can be thinned and replenished at the 3-4 leaf stage, and then watered and topdressed in time. Spraying Chinese cabbage with bilica foliar fertilizer at the right time can prevent the infection of pathogens and promote the healthy growth of seedlings.

4. Transplanting and colonization.

Before transplanting, the field should be watered thoroughly, apply sufficient base fertilizer, pay attention to timely transplanting, carry out reasonable dense planting, water immediately after planting, and timely spray 800 times of the new high-fat film, which can reduce transpiration.

Promote the rapid adaptation of cabbage seedlings to the new environment.

Chinese cabbage is not bad when frozen at minus four degrees, and some people like to eat frozen cabbage very much. If you say you don't want him to move, you put it away.

Dear, hello, I'm glad to answer for you, cabbage will be frozen at minus 2 degrees, but it will not freeze to death, and finally the outer layer of leaves will be frozen, cabbage is very cold-resistant, cabbage will generally be affected by freezing in the environment of minus 8 °C to minus 11 °C. Cabbage has a strong resistance to low temperature, and when the temperature first core degree reaches minus 3, if it can gradually rise, it can also resume growth; However, after the temperature reaches minus 8, if the temperature continues to drop to about minus 11, the Zhiyu digging will not be able to resume normal growth and will suffer from frost damage.

If you are in the world of minus 2 degrees, there will be some freezing, but it will not freeze, if you are afraid of the car, you can still do some anti-freezing measures, after all, there are many wide seeds, if the temperature drops sharply, it will also suffer heavy losses.

Generally, Chinese cabbage is at minus four degrees, and it will not be smooth and frozen, but if the Liangbei Cave is more dry, it will become frozen cabbage. Take the food back to the warm room and it will ease up in time.

Chinese cabbage should not freeze at minus 4 degrees Celsius. If the cabbage is slightly frozen, it will also be relieved indoors.

Chinese cabbage will not freeze at minus 4 degrees. Cabbage is originally distributed in North China and is widely cultivated throughout China. Cabbage, such as God, is more hardy and prefers a cool climate, so it is suitable for growing in the cold season.

If it is cultivated in the high temperature season, it is easy to cause diseases and insects, or the quality of inferior slag jujube is lost, and the yield is low, so it is not suitable for cultivation in summer. It is very resistant to low temperatures. After the temperature reaches -3, if the temperature can gradually rise, the rock can also resume growth, but if it reaches -8, it will not work.

Autumn cabbage will not freeze at minus 6 degrees.

In winter, the minimum temperature is minus 5 degrees Celsius.

When left and right, the Chinese cabbage can be stored outdoors for the winter, and the outer leaves can be dried to keep the interior warm. If the temperature is lower, cellaring is required.

1. Cabbage is very resistant to low temperatures. After the temperature reaches -3, if the temperature can gradually rise, it can also resume growth, but if it reaches -8, the temperature continues to drop to about -11, it can not resume normal growth and suffer from frost damage.

2. Cabbage is suitable for planting in loam, sandy loam and black loess with fertilizer, water retention and rich in organic matter, not suitable for planting in sandy soil that is easy to leak water and feces, and even more unsuitable for planting in clay soil with poor drainage.

3. Cabbage was originally distributed in North China and is widely cultivated in various places. Cabbage is hardy and prefers a cool climate, so it is not suitable for planting on poorly drained clay soil. Cabbage is rich in nutrition, the leaves can be fried, raw, salted, pickled, and the leaves that fall off the outer layer can still be used as feed, which has certain medicinal value.

4. Autumn cabbageThere are several other ways to store cabbage in winter in the too cold north, such as pickling Korean winter vegetables in northern Korea and eastern Northeast China.

In areas of western Northeast China, eastern Inner Mongolia and northern Hebei Province, where there was a shortage of salt before the cold, it was customary to store Iwate cabbage by pickled cabbage and other methods.
