Why are the cauliflower all scattered now?

Cauliflower, vitamin C content is very high, very popular, in recent years, there are more and more people planting, and its position in the market is also relatively stable, in general, the demand is still relatively large, at least I am in our vegetable market, you can see the shadow of cauliflower all year round.

Of course, it is not easy to grow cauliflower, and there are often many thorny problems in the planting process, among which the most common is the problem of scattered flowers. In fact, when you buy in the market, you will find that the cauliflower you buy is relatively compact, and you rarely see the cauliflower with scattered flowers.

Therefore, the problem of scattered flowers must be paid attention to, which not only affects the quality of cauliflower, but also directly affects the income. So, what can we do to reduce the problem of scattered flowers in the planting process?

First of all, we need to know that the reason for the emergence of scattered flowers is that the water is not in place at the seedling stage, the root system is injured during the planting process, and the third is that the fertilization at the rosette stage is unreasonable, the nitrogen fertilizer is missing, and the fertilizer and water at the balling stage are not in place. Once you understand the reason, it's simple, you just need to take reasonable measures according to **.

1. Seedling stage. Cauliflower is very sensitive to water at the seedling stage and is more water-loving. When we are watering, we should pay special attention to watering the bottom of the water, on this basis, when the seedlings grow 1 true leaf, we should water every 2-3 days, pay attention to grasp the interval, not too early or Taiwan, otherwise it is easy to lead to leaf growth, flower bulbs scattered.

2. Transplanting. In order to ensure the number of seedlings, the nutrient area of a single plant can be appropriately expanded to cultivate strong seedlings. When the seedlings have grown 6-8 true leaves, choose a plant with a well-developed root system, and then transplant it.

When transplanting, be careful not to bring large soil clods, be careful not to hurt the root system, and the action should be smaller and lighter when transplanting.

3. Fertilization. During the seedling period, keep the application of nitrogen, phosphorus and potassium in place, reasonable, and do not lack nitrogen fertilizer. When planting, apply 5000 kg of organic fertilizer, 50 kg of diammonium sulfate, 30 kg of potassium sulfate, 5 kg of micro fertilizer per mu, and apply sufficient and comprehensive bottom fertilizer to keep the nutrition in place and ensure better growth of plants in the later stage.

There is also a situation where cauliflower varieties are not self-wrapping and cannot protect the flower bulbs by themselves, keeping the color normal, and the flower bulbs do not scatter. In this case, artificial leaf wrapping can be carried out. Fold 2-3 leaves towards the flower bulb, taking care not to tighten them too tightly or break the leaves.

Cauliflower seedlings are sensitive to water. When the bottom water is sufficient, when the seedlings grow the first true leaves, they should be watered every 2-3 days. Before planting, the water should be properly controlled.

Late-maturing varieties should be properly watered when the diameter of the flower bulb reaches 2-3cm after squatting. Too early or overwatering can cause the leaves to stop growing, or cause the flower bulbs to fall apart. However, early spreading can also occur if watering is insufficient or too late.

Therefore, in the growth period of cauliflower should be watered reasonably, watering should grasp the correct time, watering time should not be too large, can take many times of small watering.

Seedling management. In the cauliflower seedling stage is still in the low temperature season, so to do a good job of cold protection measures, you can use plastic film mulching or straw mats and other methods to keep the temperature between 17-20 degrees, the lowest should not be lower than 8 degrees. In order to form strong seedlings and lay a solid foundation for high yield, nutrient bowls or nutrient bags should be used to raise seedlings, and the nutrient area of a single plant should be appropriately expanded.

When transplanting, soil should be taken and the root system should not be damaged.

Balanced fertilization. Before planting, 3000-5000 kg of high-quality decomposed organic fertilizer should be applied as base fertilizer per mu, which can provide sufficient nutrients for the whole growth period of cauliflower. 50 kg of diammonium sulfate, 30 kg of potassium sulfate and 5 kg of micro fertilizer were applied per mu during planting.

Tie or fold.

To prevent the flower bulbs from turning yellow or yellowish, you can tie a few leaves in the center of the cauliflower clean, or you can fold 2-3 leaves onto the flower bulbs, but the leaves should not be too tight or broken, this method also prevents the flowers from falling apart.

The symptoms of "scattered flowers" of cauliflower are the process of cauliflower swelling in the flower bulb, and the symptoms are mainly manifested as the early elongation of cauliflower branches, and the elongation length is not uniform, which is easy to cause the cauliflower flower bulb to spread out and grow outward. The final cauliflower bulb is loose and uncarnable, which affects the overall quality. In addition, some cauliflower flower bulbs will also appear purple-green velvety flower branches, and after a period of growth, the flower branches will form flower buds, resulting in the whole flower bulb in the shape of chicken feet.

It not only reduces the edible value and commerciality, but also greatly reduces the yield.

There are 2 kinds of cauliflower that we can buy, one is the one that grows relatively tight, and it is called "tight cauliflower"; There is also a kind of flower that grows loosely, which is called "loose cauliflower", what is the difference between them?

It is estimated that many people have noticed that the name of this "loose cauliflower" in the supermarket is "organic cauliflower", which is twice as expensive as ordinary tight cauliflower.

It should be that the yield is too low, and after a long time of manual selection, hybridization and cultivation, there is now this spherical cauliflower, also known as tight cauliflower.

Later, someone found that planting some pine cauliflower can be sold under the name of "organic cauliflower". So now most of the market is pine cauliflower.

There are still some differences between the two.

1. Nutrition: vitamin C of pine cauliflower

The soluble sugar content is significantly higher than that of cauliflower.

high, the other ingredients are not much different.

2. Taste: Pine cauliflower tastes crispier, while tight cauliflower tastes softer and rotten.

3. Method: Pine cauliflower is most suitable for dry pot cauliflower, crisp and flavorful. Tight cauliflower, on the other hand, is not resistant to cooking, so it is more suitable for shabu-shabu, or as a cold salad.

What spreads out is inorganic cauliflower, and what doesn't spread out is organic cauliflower of the old variety.

The quality is poor, that's it...

Pine cauliflower, also known as loose cauliflower, organic cauliflower, and ordinary cauliflower, that is, the tight cauliflower that we often use to distinguish from pine cauliflower, are two different types of cauliflower in the cruciferous family.

If it's too ripe, it will explode.

Being overly mature is like that, it's normal.

There are several reasons why cauliflower is scattered, first of all, the variety is different, some cauliflower is such a variety, and there is also because of water and fertilizer The cauliflower is scattered.

1. The reason why cauliflower is scattered.

1. The variety is not suitable.

The varieties grown are not suitable for growing locally. For example, some early-maturing varieties in the south only need more than 10 days to pass the vernalization stage, and when the plant is planted in the spring in the north, the stems and leaves of the plant do not grow large enough.

2. Seedlings are stunted.

Cauliflower bulb formation must have sufficient leaf area. If the seedling stage is affected by drought or low temperature for a long time, the growth is inhibited, and the aging seedlings are formed, and scattered balls are easy to appear after planting.

3. The planting time is unreasonable.

The suitable temperature for the growth of cauliflower leaves was 8 24, and the suitable temperature for the growth of flower bulbs was 15 18. If the planting is too early, it will be affected by low temperature, the stems and leaves will not grow, and scattering will occur; If the planting is too late, the flower bulbs will quickly elongate to form loose balls in high temperature weather during the growth period.

4. Insufficient water and fertilizer.

Cauliflower likes water and carries hidden fertilizer, if the water and fertilizer are insufficient after planting, the leaves cannot grow, which is easy to cause the flower bulbs to be small and scattered. or water shortage and drought after flowering, partial application of nitrogen fertilizer, etc.

5. It is too late to harvest the Speech Hall.

After the flower bulbs are fully grown, they are not harvested in time, causing the flower branches to continue to grow.

Second, the precautionary measures of cauliflower loose balls.

1. Scientific introduction.

Varieties suitable for local spring cultivation should be planted, and if they are introduced from other places, they should be tested before being used for production.

2. Raise seedlings with a nutrient bowl or plastic bag.

The diameter of the nutrition bowl or plastic bag should not be less than 8cm. The temperature at the seedling stage is kept at 15 20 during the day and 10 12 at night to prevent drought. Strong seedling standard: there are 7 8 leaves, the leaf area is large, the stem is thick and the nodes are short, the root system is developed, and the plant height is about 13cm.

3. Planting at the right time.

Spring cauliflower is best selected from mid-late maturing varieties, sown in October-November, and planted in January-February of the following year.

4. Water and fertilizer management.

Before planting, apply 2000-3000kg of high-quality farmhouse fertilizer per mu, apply 10kg of ammonium sulfate per mu during planting, water enough root water, and water the seedlings once after the seedlings. After flowering, combined with irrigation and top dressing 2 times, each time 15kg of ammonium sulfate per mu. During the bulb expansion stage, potassium dihydrogen phosphate, borax and ammonium molybdate were sprayed to prevent premature plant senescence and improve yield and flower bulb quality.

5. Harvest at the right time.

Cauliflower should be harvested in time after maturity, the harvest is too early, the yield is low, the harvest is too late, the flower bulbs are loose and easy to form scattered flowers, and the commerciality of the flower bulbs declines. The criterion for timely harvesting is that the flower yards on the edge of the flower bulb begin to roll downward, indicating that the flower bulb has grown sufficiently and should be harvested in time.

First, the reason for the cauliflower scattering.

1) The introduction is wrong.

The introduced varieties are not suitable for local growth, such as some early maturing varieties in the south only need more than 10 days to pass the vernalization stage, and the stems and leaves of the plants do not grow enough to be too big and blind when planted in the spring in the north.

2) Poor seedling quality.

For example, the density of seedlings is too large, or the number of seedlings is too large, or the root system is damaged during seedling division, or small old seedlings are raised, or the seedling age is small.

3) Extensive field management.

If the planting period is early, the stems and leaves cannot grow due to low temperature. Or the planting period is late, and the flower bulb growth period encounters high temperature weather. or too densely planted, or excessive squatting, etc.

4. Insufficient water and fertilizer.

After planting, the stems and leaves cannot grow due to insufficient water and fertilizer, or lack of water after flowering, or partial application of nitrogen fertilizer.

5) Temperature, light and water adjustment are not in place.

In early spring, management measures such as temperature, light, watering, and ventilation are not in place.

6) Harvest too late.

After the flower bulbs are fully grown, but harvested too late, the flower branches continue to grow.

7) Pest and disease hazards.

Pests and diseases in the field harm the plants, so that the plants grow poorly, and they are easy to form loose balls.

Second, cauliflower scattered flower control measures.

1.Reasonable watering at the seedling stage.

Cauliflower is particularly sensitive to water in the seedling stage, so farmers should pay special attention when watering, when the bottom water is sufficient, when the seedlings grow 1 true leaf, water every 2 3 days, not too early and not too late, otherwise it will lead to leaf growth and flower bulbs scattering.

2.When transplanting seedlings, take care of the root system.

When raising seedlings, you can use a nutrient bowl or a nutrient bag to raise seedlings, and appropriately expand the nutrient area of a single plant, so that the cauliflower can form a healthy seedling, that is, 6 8 true leaves, and the root system is developed. Be careful, don't bring a big * lump, don't hurt the roots, and protect the root system.

3.Control pests and diseases.

Actively control pests and diseases to reduce the damage to plants.

4.Strengthen field management practices.

Apply sufficient basal fertilizer and plant moderately densely. According to the growth stage, water and top dressing at the right time. In summer, shade netting can be covered to reduce the effects of high temperatures during balling. Cultivated in protected areas should pay attention to the wind, and the shed temperature is 20 25 during the day (not more than 25) and 10 12 at night.

To sum up, the reason for the phenomenon of scattered flowers caused by cauliflower balling is not tight and preventive measures, cauliflower growers can refer to it before planting cauliflower.

First of all, we need to know that the reason for the emergence of scattered flowers is that the water in the seedling stage is not in place, the second is that the root system is injured in the planting process, and the third is that the fertilization at the rosette stage is unreasonable, the nitrogen fertilizer is missing, and the fertilizer and water at the bulbous stage are not in place. Knowing the reason, it's simple, you only need to take reasonable measures according to **, key scattering.

The reason why cauliflower will be "scattered" in the planting process is that one is the impact of lack of water at the seedling stage, and the other is the planting time, which hurts the root system; Or it is the lack of nitrogen fertilizer at the rosette stage, the unreasonable fertilizer and water at the balling stage, and the untimely harvesting time;

Therefore, farmers can "prescribe the right medicine", and take timely prevention and control measures according to the first nuclear system!

The cauliflower that spreads out is called pine cauliflower, organic cauliflower.

There is no difference between cauliflower and cauliflower, they are the same thing, only the name of the region is different. It is called cauliflower in the north and cauliflower in the south.

It's the same thing, so why do you have to say it's two? Scattered flowers are just two more days of cauliflower and a little older! It's like when a person is young and when he is old, the color will change. It's a truth.

The full name of loose cauliflower is green stalk pine cauliflower, the flower stalk is greener than the general cauliflower, because the flower stalk is more slender and the flower bulb is loose, so it is called loose cauliflower; The main difference is to see the color of the flower stalk, from the taste, the green stem pine cauliflower is resistant to cooking, crisp but not rotten, and the sugar content and vitamin content are higher than that of ordinary cauliflower. The planting management is not much different from ordinary cauliflower, but it is more sensitive to temperature, and the climate will seriously affect the looseness and beauty of the flower bulbs. In terms of the types of pine cauliflower, there are currently three kinds of ripeness: early, middle and late; In terms of looseness, it is also divided into full loose and semi-loose.

Cauliflower is naturally occurring.

Cauliflower, also known as cauliflower, cauliflower or cauliflower, cauliflower is an annual plant of the brassica family of the cruciferous family, also known as cauliflower, cauliflower, cabbage, cauliflower, and Brussels sprouts. Native to the eastern coast of the Mediterranean.

Cauliflower, biennial herb, 60-90 cm high, powdered. The stems are erect, stout, and branched. basal leaves and lower leaves oblong to elliptic, long centimeters, grayish-green, rounded at apex, spreading, not curly, entirely or finely toothed, sometimes the leaves are extended, with several small lobes, and wing-shaped; petioles 2-3 cm long; The middle and upper leaves of the stem are small and sessile, oblong to lanceolate, and hold the stem.

At the tip of the stem, there is a milky fleshy capitate densely composed of a peduncle, peduncle and undeveloped flower buds; racemes apical and axillary; The flowers are pale yellow, then turn white. The longhorn fruit is cylindrical, 3-4 cm long, with 1 midrib, the beak is thick at the lower part and thin at the top, 10-12 mm long. The seeds are broadly oval, nearly 2 mm long, and brown.

The flowering period is April, and the fruiting period is May.

It has the effect of anti-cancer and anti-cancer disease. Among the many fruits and vegetables, cauliflower and Chinese cabbage have the best anti-cancer effect. Cauliflower contains isothiocyanate compounds and trace elements, which have antioxidant properties, and long-term consumption of cauliflower can reduce the incidence of cancers such as rectal, breast and gastric cancer.

Contains flavonoid compounds, which have the effect of protecting the cardiovascular system. Flavonoids can prevent infection, are the best blood vessel cleaners, can stop cholesterol oxidation, prevent platelets from clotting, can reduce blood clots, can reduce the risk of heart disease and stroke, and have a low mortality rate from coronary heart disease. And cauliflower is one of the vegetables that contains the most flavonoids.

It is rich in vitamin K. It has the effect of preventing internal bleeding and hemorrhoids, reducing heavy bleeding during menstruation, and promoting normal blood clotting. Some people suffer small bumps and injuries but are not easy to recover because of the lack of vitamin K in the body.

Cauliflower is rich in vitamin K, which is not found in ordinary vegetables.

Cauliflower is rich in VC, with 85 100 mg of VC per 100 grams of cauliflower, which is 4 times higher than that of Chinese cabbage. It has the effect of detoxifying the liver. Eating more cauliflower will also thicken the walls of blood vessels, which are not easy to rupture.

VC can enhance the liver's ability to detoxify, improve the body's immunity, and prevent the occurrence of colds and scurvy. Cauliflower is rich in selenium and VC, as well as carotene, which has a certain inhibitory effect on stopping precancerous cell lesions.

There are abundant biologically active substances. There are also a variety of indole derivatives active substances in cauliflower, which can reduce estrogen levels and reduce the incidence of breast cancer. Cauliflower also contains carotene, which can improve the activity of carcinogens and detoxification enzymes and prevent the occurrence of cancer; In addition, cauliflower also contains thiophenolthione, which can whiten the skin, reduce the enzyme of melanin formation and prevent the formation of **pigment spots, and can also be smooth and appetizing when eaten regularly.

Cauliflower has a high water content. It has a water content of more than 90% and is low in calories, so it can fill the stomach without obesity for those who want it.
