What color is the freshly sprouted leaves of purple Chinese cabbage?

And grow into a color, basically will not change color.

Purple Chinese cabbage is one of the varieties of colored Chinese cabbage, its leaf color is different from the green, yellow-white of ordinary Chinese cabbage, and there are yellow, red and so on on the market.

Purple Chinese cabbage has strong disease resistance and high yield.

When the purple cabbage first sprouts, the leaves are tender purple. Then it grows and turns a deep purple color.

Eating Chinese cabbage is tempered, he should be yellow, it will be purple is the liquid of general food, it is yellow.

When the purple cabbage first sprouts, the leaves are also green, and when it slowly matures, it will turn purple.

will change color.

Thought to have sold fake purple cabbage seeds.

No. This is normal.

It hasn't changed for a while, it's a fake seed, and I can't tell it yet.

The first reason why the cabbage field is yellow is because the land is too dry due to insufficient watering. This reason will cause the cabbage to turn yellow, if the weather is dry, the cabbage will not be replenished with water for a long time, the cabbage will turn yellow, and even dry up and die.

In a humid environment, when the soil is moist or even when water accumulates, the soil will become less permeable. The root system of the cabbage in the ground will rot and die. In this way, the baby cabbage will naturally turn yellow.

The soil is too fertile. Baby cabbage grown in overly fertile soil will also turn yellow. This is not a fantasy, but because when the cabbage grows, the demand for fertilizer is not particularly large, but many people will use a lot of base fertilizer when planting cabbage.

Cabbage can also cause cabbage leaves to turn yellow because of excessive nutrition.

The last reason why cabbage is easy to turn yellow is that the soil environment is not suitable. Because when planting cabbage in rural areas, it is rare to plant it for many years. When planting in rural areas, it is more about rotation and intercropping.

The leaves of bok choy are yellow, and there are generally the following reasons:

One is yellow, that is, too much water causes the soil to accumulate water for a long time, poor air permeability and even some fibrous roots rot. It shows that the young leaves are dark yellow and dull, and the new shoots are shriveled.

The second is fat yellow, that is, fat, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny, but generally uneven and unstretched. You can sprinkle a layer of radish seeds and pull them out after a few days of emergence to consume nutrients.

The third is dry yellow, due to long-term lack of watering or dehydration, although the new leaves are normal in color, the lower leaves gradually dry up and fall off and age.

Fourth, it is alkali yellow, and the water quality in the north is alkaline, and the leaves gradually fade, turn yellow or even fall off. The easiest way to do this is to pour fermented rice washing water or rainwater.

The yellowing of Chinese cabbage leaves can be caused by lack of fertilizer, excessive soil moisture, insufficient moisture, or insect infestation. Cabbage is a common vegetable in daily life, and its leaves are generally green in color, but sometimes you can see yellow leaves of Chinese cabbage, and there are many reasons for this.

1. The yellowing of Chinese cabbage leaves may be due to lack of fertilizer and malnutrition, and the leaves will be yellowed due to lack of nutrients.

2. The soil moisture of planting Chinese cabbage is too much, which causes the roots of Chinese cabbage to rot, and the cabbage leaves will lose their luster and gradually turn yellow.

3. Lack of water, which is similar to lack of fertilizer, is caused by insufficient nutrients to cause yellowing of leaves.

4. Insect infestation occurs in cabbage.

Yellowing of the leaf edges of vegetables (Chinese cabbage) is caused by a lack of trace elements. For example, potassium deficiency in Chinese cabbage will cause white or yellowish-white spots of different sizes to appear on the edge of the leaves, and then expand and become blighted spots, and finally the leaf edges will wither due to bacterial infection, and the old leaves will wilt and fall off early; For example, the lack of calcium in cabbage will cause the inner leaf margin or concentric leaves to turn brown and dry up; Magnesium deficiency can also cause vegetable leaves to turn yellow (white) from the edges, gradually extending inward or yellowing and whitening of all leaves except for the sides of the veins.

Prevention and control methods: corresponding measures can be adopted according to specific symptoms. For example, potassium deficiency can be used as a potassium fertilizer.

Calcium deficiency is available. 5% calcium chloride foliar spray, 1 time every 7 days, 2 3 sprays in a row; If the soil is acidic and calcium deficient, lime can be applied. Magnesium deficiency can be sprayed with 1% 2% magnesium sulfate on leaves, 5 7 days 1 time, spray 3 5 times; Calcium, magnesium and phosphorus fertilizers can also be applied, and the application rate of potassium and nitrogen fertilizers can be appropriately controlled.

Summary. 1. Lack of water cabbage needs sufficient water in the growth process, when breeding cabbage, if the watering is too little, it will lead to a lack of water in the plant, which will make the leaves of the cabbage yellow, and it needs to be watered 1-2 times every other week to keep the soil moist, but in the rainy season, it is necessary to discharge the water in the soil for the cabbage to avoid its poor growth. 2. Excessive fertilization of cabbage is not tolerant of thick fertilizer, breeding cabbage, if it is fertilized too much, it will lead to fertilizer damage to the plant, which will make the leaves of cabbage rot and yellow, and it is necessary to adjust the frequency of fertilization according to the growth state of the plant, and regularly spray potassium dihydrogen phosphate on the leaves of cabbage to delay the senescence of plant leaves.

3. Soil alkaline cabbage is suitable for growing in slightly acidic soil, when breeding cabbage, if the soil is alkaline, it will lead to poor plant growth, which makes the leaves of cabbage yellow and wilting, it is necessary to apply ferrous sulfate in the soil to adjust the acidity and alkalinity of the soil, and when watering cabbage, alkaline water can not be used. 4, the control of pests and diseases of the leaves of the cabbage yellowing may be caused by pests and diseases, the maintenance of cabbage, the need to regularly observe the growth state of the plant, if found on the leaves of the cabbage on the insect spots, it is necessary to uproot the seriously infected disease plant and burn, and to spray 1-2 times every other week sterilization agent, so that the cabbage healthy growth.

Yellowing of cabbage leaves may be caused by lack of water, excessive fertilization or alkaline soil, when breeding cabbage, it is necessary to water 1-2 times every other week to keep the soil moist, and fertilize according to the growth state of cabbage, so as to avoid its fertilizer, and to apply ferrous sulfate to the soil to make the soil slightly acidic.

Purple cabbage, a biennial herb of the cruciferous family Brassica. It is highly adaptable, hardy to cold and heat, and more resistant than ordinary cabbage.

The whitish leaves of greens may be due to white rust, which mainly affects leaves. In the early stages of the disease, there will be a slight bulge on the back of the leaf with white nearly round to irregular blisters, known as spore piles. Its surface is slightly shiny, and some leaves have dozens of blisters, and the mature blistering epidermis is broken, emitting a white powder, that is, the sporangia of the germ.

The control methods of green cabbage white rust are as follows: alternate crop rotation with non-cruciferous vegetables; After the vegetables are harvested, the disease residues in the field are removed to reduce the source of bacteria;

In addition, at the beginning of the disease, 25% methalene wettable powder can be sprayed 800 times, or 50% methalene copper wettable powder 600 times, or 58% methamanine manganese zinc wettable powder 500 times, or 64% alum wettable powder 500 times, sprayed 50 60 liters per mu, once every 10 15 days, and 1 to 2 times for prevention and control.

What are the precautions for planting greens?

In the process of planting greens, the seeds are first sown in the wet soil for germination treatment, and then an appropriate amount of compound fertilizer solution is added to the soil as the base fertilizer, so that it is fully stirred, and the spacing between each plant is kept at about 15 20cm when planting, and the soil is kept moist, and the urea solution can be applied every 2 3 weeks or so.
