Why is red cabbage green when it just sprouts?

<> "Red cabbage is a purplish-red leafy vegetable, but its shoots are green when they first start growing because of the high amount of chlorophyll in its leaves. Chlorophyll is a pigment necessary for plants to carry out photosynthesis and is able to absorb light energy and convert it into chemical energy needed for plant growth. As the leaves gradually develop red, the chlorophyll gradually decreases, while other pigments such as carotenoids and anthocyanins begin to emerge, giving the red cabbage a distinctive purple-red color.

Red spinach? Ornamental and edible are not wrong, master 3 planting skills, you can also plant.

Spinach is a common vegetable and is popular with many people because of its delicious taste and rich nutrition. Spinach is always seen in small vegetable gardens, and we have introduced many ways to grow spinach. A friend asked today

I saw a kind of red spinach the other day, the red color is very beautiful, it looks very appetizing, I don't know how it really tastes. ”

I said, "If you want to know the taste, you can buy some and fry a plate at home." He said

Don't dare to taste it, there are some things, the brighter the color, the more toxic it is, haha. "Haha, are you worried that this vegetable is not safe? It's also good to plant your own for viewing!

In fact, red leaf spinach is a new type of spinach, and it is not a genetically modified vegetable. And the planting method is also very simple, very suitable for planting in a small vegetable garden, friends who like to grow vegetables on the balcony can also try to plant red leaf spinach, which can not only be used for ornamentation, but also eaten, and picked at any time.

First of all, make a clearing, water it once before sowing to keep the soil moist, sprinkle the spinach seeds directly, and cover it with a thin layer of soil, the thickness of which does not exceed centimeters.

Then, after sowing, also keep the soil moist, too dry soil, you can sprinkle it once. Because it is grown and eaten by itself, it is not suitable for pesticides, so you can spray a little amino acid foliar fertilizer to promote the growth of spinach. The suitable temperature during the day is 15 25, and at night it is not less than 5.

Finally, the young leaves of the spinach are green in color, but the veins are red, and after a few days, once all the leaves of the spinach are full, the entire leaf including the stalk is already red.

Although the planting method is similar to that of ordinary spinach, there are many fake seeds nowadays, so it is recommended to buy them from regular channels. Therefore, the cultivation of red leaf spinach is still very simple, very suitable for planting in a small vegetable garden or balcony, a red leaf, but also a beautiful scenery, ornamental and edible.

Baby yellow.

Oily wheat cabbage, also known as wheat cabbage, also known as bitter cabbage, lettuce, belongs to the Asteraceae family, lettuce plant, is a young shoot, young leaves as the product of the pointed leaf lettuce, the leaves are long lanceolate, the color is light green, the texture is crisp and tender, the taste is extremely fresh, fragrant, has a unique flavor, contains a large amount of vitamin A, vitamin B1, vitamin B2 and a large amount of calcium, iron, and other nutrients, is the top grade in raw vegetables, there are"Anchovy"called.

Planting season. August-September (sowing in all seasons, suitable for indoor planting in northern winter).

Seedling 1, often seedling transplanting. The suitable temperature for germination is 15 to 20, higher than 25 or lower than 8 does not germinate, and the sowing of oilseed wheat rape in summer high temperature needs to be promoted. Spread the seeds on the surface of the watered soil, cover the soil about centimeters, keep the soil moist, and germinate about l weeks.

Germination method: soak the seeds in water for 5 6 hours, wrap them in a damp cloth after a little drying, and put them in a cool place to germinate, about 3 4 seeds are sown when they are white. )

2. The soil can be kept moist at the seedling stage, and shaded in the summer when exposed to the sun. When the true leaves are 3 or 4 pieces, they are planted in the potting soil with sufficient basal fertilizer, the plant spacing is about 10 15 cm, and they are watered thoroughly, and they can be managed normally after about 1 week.

Day-to-day management. 1. Fewer pests and diseases, rapid growth, large amount of fertilizer, a large amount of fertilizer, a wheat rape like every 7 10 days or so spray 1 time with nitrogen fertilizer-based rotten organic fertilizer, in order to promote the growth of leaves, before harvesting l week should stop fertilization.

2. Like cool, slightly cold-tolerant but not heat-resistant, the appropriate temperature for leaf growth is 11 18, and the temperature is too high to affect growth or early flowering.

3. It likes moisture, and it is required to give sufficient water during the vigorous growth period, usually watering once a day, and watering in the morning and evening if necessary, so as not to affect the quality of the leaves.

4. After harvesting, after the wound is dried, Trim water-soluble fertilizer can be applied once to promote the germination of new leaves, and it can be harvested again after a period of time.

Harvesting begins about a month after planting, or from about 15 leaves, usually in the morning, when the fully grown, thick, brittle green leaves are broken off by hand.

It's just sprouting, it's white, it's white, it's not the color of a clatter, and when the sun comes down, it's going to turn green.

When the rape first sprouts, there are green, red and red, what varieties to see?

Well, all the dishes are generally green and light green when the tooth is extracted.

There are vegetables that are sold, and when the vegetables are just sprouted, they are pink id, so you must pay attention.

Oilseed lettuce is light yellow when it first sprouts.

Let's be green when it sprouts.

The green ones are all green, but they are tender green, and then they change.

It's a little red, and when it comes out, it's green.

It's just sprouting.

It's white.

The white ones don't have the color of the clatter.

When the socks come down, the sun will turn green as they age.

The temperature is too high. Green vegetables are overwintering crops, afraid of heat and not afraid of cold, the weather has been unpredictable recently, the scorching sun for a while, the heavy rain for a while, high temperature and humidity are easy to cause rot. My family's amaranth was not harvested in the first half of this year, and it was all rotten. Recently, the seedlings are similar to yours.

Is it that the weather is not so warm, and the wind blows the buds that have just come out and wither. The newly sprouted shoots were planted in plastic for a few days, and now the spring breeze is too big. When it's warm, it's fine.

The reason for the sprouting and wilting of the vegetables planted by themselves is that there are insect pests in the roots, the second is that there are diseases, and the third is improper use of fertilizer. Hope you can help you.

The vegetables you grow wither as soon as they sprout, whether the seeds just sprout and wither, or the seedlings you planted wither as soon as they sprout. It could be a lack of water, a lack of nutrients, a soil problem, or an improper planting method.

It is probably caused by the lack of nutrients and water in the soil, and the dry and hard soil is the cause of the wilting of vegetables.

I think it should be the relationship between the soil and the quality.

There are many reasons, the ground is too dry, too much fat, the sun is too big, and the temperature is high.

Potatoes turn green when they sprout.

Potato sprouting produces a toxin called solanine, also known as solanine. Potatoes contain only 10 mg of solanine per 100 grams, while solanine can be increased by 50 times or more in green, sprouted, and rotten potatoes. Eating a very small amount of solanine may not be obvious harmful to the human body, but if you eat 200 mg of solanine at a time (about half a tael of potatoes that have turned green and sprouted) after 15 minutes to 3 hours, you can develop the disease, stomach burning, tongue and throat numbness, nausea, vomiting, abdominal pain, diarrhea, body temperature rise in severe poisoning patients, headache, coma, sweating, palpitations.

Children often cause convulsions and coma.

If you eat 300 400 mg or more solanine, the symptoms will be severe, manifested as increased body temperature and repeated vomiting resulting in dehydration, as well as dilated pupils, photophobia, tinnitus, convulsions, dyspnea, blood pressure drop, and very few people can die due to respiratory paralysis. Therefore, patients with severe symptoms should be sent to the hospital as soon as possible**.

If you feel a little numb in your mouth when eating a potato, it indicates that the potato also contains more solanine, and you should stop eating it immediately to prevent poisoning.

Precautionary measures :

Potatoes should be stored in a low-temperature, ventilated place without direct sunlight to prevent germination and greening.

Do not eat when there are too many buds or when most of the skin and flesh turn black or green.

For potatoes that sprout very little, the flesh around the sprouts and sprout eyes should be thoroughly removed. Because solanine is soluble in water, it can invade the water and soak for about half an hour.

Hope it helps.

In this case, why do the vegetables you grow wither as soon as they come out? There should be two reasons for this situation, one is being bitten by a bug and the other is being burned to death by chemical fertilizer.

The vegetables planted withered as soon as they sprouted, so check for underground pests.

This can happen when the temperature is low, the water is lacking, the sunlight is too strong, or there is too much fat.
