Can chrysanthemum at minus two degrees be frozen and will be on the market in 10 days?

Artemisia chrysanthemum will freeze to death at about 5 degrees. Chrysanthemum is a semi-cold-tolerant vegetable, when the temperature is lower than 10 degrees, the growth is slow, the growth is poor, the minimum tolerable growth temperature of chrysanthemum is about 8 degrees, when the temperature drops again, chrysanthemum will appear frostbite, resulting in freezing to death. In order to avoid chrysanthemum frostbite and freeze to death, you can choose to plant in the greenhouse, so that you can control the temperature and avoid frostbite.

Summary. Hello dear, chrysanthemum can't be eaten if it's frozen, so it's recommended to throw it away. When the temperature is lower than 10 degrees, the growth of chrysanthemum is slow, the growth is poor, and the minimum can tolerate the growth temperature of about 8 degrees, when the temperature drops again, the chrysanthemum will have frostbite marks, and even freeze to death.

In order to avoid frostbite and freeze to death in winter, chrysanthemum can be planted in greenhouses, and when planted in the open field, it can also be covered with film and straw, and it can be opened and ventilated when the temperature is high.

1. Selection of good seeds: Artemisia chrysanthemum is generally planted by the method of sowing seeds, and the seeds of chrysanthemum with strong disease resistance, strong stress resistance and high yield are selected in advance. 2. Fertilization of land preparation:

Choose loose, breathable, well-drained soil for planting, you can tidy up the soil before planting, apply enough rotted base fertilizer in advance, and then apply a little diammonium phosphate, evenly sprinkle the fertilizer into the soil, and rake the soil flat to make a flat furrow. 3. Sowing chrysanthemum: sowing can be done by sowing or strip sowing, the seeds are evenly sprinkled into the soil, and then covered with about 1 cm of soil, the soil is paved and pressed well, watering to maintain soil moisture, and promoting germination and germination of small seedlings.

4. Field management: When the seedlings grow to about 10 cm, the seedlings should be pulled out in time, and the weeds should be removed regularly, and watered and fertilized regularly.

<> large-leaved chrysanthemum is generally afraid of freezing, and small-leaved chrysanthemum is generally not afraid of freezing. Artemisia macrophylla, also known as chrysanthemum or round-leaved chrysanthemum, is characterized by large and thick leaves, few and light missing moments, green color, spoon-shaped, soft texture, less fiber, more heat-resistant, but poor cold resistance, suitable for cultivation in the southern region; Artemisia microphylla, also known as Artemisia microphylla or Artemisia microphylla, is characterized by narrow leaves, many and deep gaps, thinner mesophyll, stronger fragrance, strong cold resistance, and is suitable for cultivation in northern areas.

Chrysanthemum is one of the green leafy vegetables, which itself contains more nitrate, if it is fried and then placed for a long time, then the nitrate contained in chrysanthemum will be converted into nitrite harmful to the human body under the action of bacteria, so it can only be stored for about 4-6 hours for fried chrysanthemum.

For chrysanthemums that have not been fried, they generally need to be stored in a cool, ventilated and dry place indoors, and they can generally be stored for about 1-3 days.

2. It is not recommended to eat it again.

Although the low temperature environment of the refrigerator can inhibit the activity of most enzymes and microorganisms, if it is stored for too long, it will also deteriorate, and it can only be stored for about 1-3 days if it is refrigerated in the refrigerator.

If the chrysanthemum has been in the refrigerator for a week, then it is likely that more microorganisms have grown in it, and even if it has not deteriorated, most of the water and nutrients contained in the chrysanthemum have been lost, so it is not recommended to continue to eat at this time.

For fresh chrysanthemum, its taste is very crisp and tender, and contains more nutrients, but with the extension of the storage time, the stems and leaves of chrysanthemum will slowly age, and the taste of chrysanthemum at this time will be rough, and the nutritional value will also decrease.

Therefore, for the aged chrysanthemum, you need to remove the aged part before cooking, leaving the more tender part, if the chrysanthemum has become too old, then it is not recommended to continue eating.

4. It is not recommended to eat it again.

Under normal circumstances, the color of chrysanthemum is mostly emerald green, and there will be no blackening, if the chrysanthemum has been blackened, then it is mostly because it has been left for too long and oxidized.

At this time, chrysanthemum will not only lose nutrients and taste will decrease, but also easily breed microorganisms and deteriorate, so it is not recommended to continue eating blackened chrysanthemum.
