What is the deal with cucumbers with white skin on their surfaces?

There are the following:

1. Pesticide damage causes cucumber skin.

Viral disease is an important disease that harms cucumbers, and whitefly is the main way of transmission of viral disease, so the control of whitefly is an important job for vegetable farmers. At present, vegetable farmers mostly use pesticides to prevent and control, and if the drug is very much or the drug time is improper, there will be pesticide damage, and some small spots will be formed on the peel, which seriously inhibits the growth of the peel, and then with the growth of melon strips, the lesions are connected into pieces, resulting in the skin.

2. The ratio of dipped anthers is unreasonable.

1.Pay attention to temperature and humidity.

When the humidity in the shed is high, if the weather is good, open a small opening for ventilation for 15 or 20 minutes about an hour after pulling the shed, reduce the humidity in the shed, and then gradually expand the ventilation. Do not ventilate when the temperature of the shed reaches more than 30 to prevent large changes in temperature and humidity. It should be noted that try not to ventilate when there is dew on the melon strips, and try to be small when starting to ventilate.

2.Prepare the right spot anthers.

Some problems due to the dipping of anthers often lead to the phenomenon of peeling in the whole shed. Due to the rapid decrease in temperature in winter, it is necessary to appropriately increase the concentration of dipped anthers, but it must be tested first and then promoted, so as to avoid the appearance of peeled melons due to excessive concentration of anthers, such as the excessive concentration of dipped anthers, which can be alleviated by foliar spraying of 6000 times more liquid.

Rational use of drugs to avoid drug damage.

When preventing and controlling diseases, many vegetable farmers think that one or two pesticides are not effective, so they always add this, add that, and sometimes even add six or seven kinds of pesticides, which is very easy to cause pesticide damage. Vegetable farmers want to use symptomatic medicine, generally 2 or 3 kinds of single dose compound is enough, there is no need to add too many types of medicines. After the temperature drops, some vegetable farmers adopt fumigation methods, such as chlorothalonil.

Smoke, pythium, etc., but the vegetable farmer's smoking time is usually more than ten hours, and the appropriate smoking time is 6 8 hours, and it is generally better to smoke in the shed at about 12 o'clock at night. When spraying, it is best to choose a sunny afternoon, especially after a cloudy day, to leave enough buffer period for the plants, generally sunny days.

Spraying is done again on the 2nd and 3rd day.

3.Timely supplement the nutrition of melon strips.

For melons caused by boron and calcium deficiency, vegetable farmers can spray full-nutrient foliar fertilizer on the foliar surface to alleviate the symptoms of nutrient deficiency. The addition of foliar fertilizers containing iron and calcium to the anthers also has a certain effect on improving the resistance of melon strips and improving the quality.

Cucumbers contain tannins, especially in the skin. Tannins are also called tannins, and they taste astringent and numb, so some cucumbers with particularly dark green skin will taste a little astringent if they are not peeled. Many foods contain tannins, such as grapes, tea, and so on.

Moderate intake of some tannins is beneficial, but don't overdo it.

The tannins precipitate from the inside of the cucumber skin and form a white layer on the surface. When you buy cucumbers, you can smell them, if there is no pesticide smell, only the fragrance of cucumbers, you generally don't have to worry too much.

What is the deal with cucumbers with white skin on their surfaces? This is just a layer of frost on the surface of the cucumber. And it's still usable.

Cucumber frosted fruit. The cultivation ground should avoid too much sand, and fertilization should be paid attention to in the later stage of growth. Nitrogen, phosphorus and potassium should be used in fertilization, and crop rotation should be noted.

Attention should be paid to conditioning the soil so that it is loose. Promote the vigorous growth of the root system and enhance the absorption capacity. In the later stage of growth, attention should still be paid to the prevention and control of pests and diseases to avoid premature plant aging.

Strengthen the ventilation and cooling, prevent the night temperature from being too high, pay attention to cleaning the greenhouse film in time, and increase the light transmittance. When using sunspot pumpkin as rootstock, cucumber is prone to frosting. When using imported Japanese pumpkin as rootstock, cucumber frost is less, so pay attention to the selection of rootstock.

That's because of the frost.

Cucumber frost fruit because the cultivation site is too sandy, and fertilization should be paid attention to in the later stage of growth. Nitrogen, phosphorus and potassium should be used in fertilization, and crop rotation should be noted.

Attention should be paid to conditioning the soil so that it is loose. Promote the vigorous growth of the root system and enhance the absorption capacity. In the later stage of growth, attention should still be paid to the prevention and control of pests and diseases to avoid premature plant aging. Strengthen the ventilation and cooling, prevent the night temperature from being too high, pay attention to cleaning the greenhouse film in time, increase the amount of light transmittance, and pay attention to the selection of rootstocks.

The white dots on the cucumber can be eaten, which means that the cucumber is very fresh. Cucumber is an annual creeping or climbing herb of the Cucurbitaceae family. The stems and branches are elongated, furrowed, and covered with white rough bristles.

The tendrils are thin. petioles slightly rough, with rough bristles; Leaves broadly ovate-heart-shaped, membranous, lobes triangular, toothed. Monoecious.

Male flowers: constant clusters in leaf axils; peduncles slender, slightly pubescent; The corolla is yellowish-white, and the corolla lobes are oblong-lanceolate. Female flowers:

solitary or sparsely clustered; peduncle stout, pubescent; The ovary is rough. The fruit is oblong or cylindrical, yellow-green when ripe, and has a rough surface. Seeds are small, narrowly ovate, white, without edges, and nearly acute at both ends.

Flowering and fruiting period in summer.

Summary. The white spots on the cucumber are the thorns of the cucumber, which is something that the plant gives birth to in self-defense, and can also prevent the evaporation of water.

There are small white spots on the outside of the skin of the dried cucumber strips dried at home, what is this, the dried cucumber strips are not rotten and grind off the lump, is it the cucumber thorns on the surface of the cucumber? The white collapse beam that became a small dot of edge.

The white spots on the cucumber are the wild thorns of the cucumber, which is the thing born from the self-defense of the cheating plant, and it can also prevent the evaporation of water.

It is said that there are small white spots on the surface of the sun-dried cucumber strips, and when I bought it, it was a fresh cucumber without small white spots, and after drying, there were small white spots, and I don't know why.

If it is long hair, it is the sclerotinia of cucumbers, which is the most common disease of cucumbers in the greenhouse in the winter season. If there is no long hair, it is a bacterial disease of cucumbers, so pay attention to it when picking cucumbers, and throw it away if it is rotten. Welcome to add questions, I hope it can help you.

I bought fresh cucumbers, not rotten cucumbers, I've eaten them three times, I don't know if there is a problem.

Small white spots of sticky matter are also dry.

The small white dot at the back is dry, not sticky.

Yes, fresh with white spots, if left for a long time, it will be broken.

When I bought fresh cucumbers, there were no white spots, only cucumber thorns, and after drying, I found that there were small white spots on the skin, and they were dry.

It's okay. The end of the thorn is so small that it can be easily rubbed off. It looks like a white dot. Just wash it off. It can be eaten with confidence.

I left the heating on my home for three days and it dried, and it didn't rot at all.

Mmmm, rest assured.

The surface of the cucumber becomes sticky because the cucumber has spoiled and cannot be eaten again.

Summer is the season for producing cucumbers, and many people also like to eat cucumbers, but cucumbers are not easy to preserve, some people will choose to put it in the refrigerator, but not all foods are suitable for keeping in the refrigerator.

Put it in a ventilated place, put the cucumber in such a steaming drawer or vegetable basket, hang it in a ventilated and cool place, ventilate and dissipate heat, control the growth of microorganisms, pay attention to not stack it indiscriminately, this way can be stored for three to five days.

When soaking cucumbers in salt water, do not pinch the head to remove the roots, and keep the cucumber intact to avoid the loss of nutrients from the cut surface during the soaking process. In addition, cold salad should be cooked and eaten freshly, and should not be left for a long time after cooking, which will also promote the loss of vitamins.

From the text description, like "**melon", as shown in the figure below:

**Melon, also known as Shilen** melon, the academic name is Elizabeth thick-skinned melon, and it is named **melon because of its golden color.

**Melon is suitable for spring cultivation in traditional melon producing areas in East China such as Jiangsu, Zhejiang, and Anhui, and is also suitable for greenhouse mulching cultivation. Shed cover cultivation is sown in mid-March, and open field cultivation is sown from the end of March to early April. Nutrient bowl seedlings, seedlings 30-35 days old.

The planting density is 1000-1200 acres, the width of the planting furrow is 2 meters, and the furrow is planted in a single row. When the main stem has 5-6 leaves, leave 4 leaves to top, select and leave 2 strong vines to crawl on both sides of the furrow, and when the vines have 5-6 leaves, they are topped twice, and 3 grandchildren are selected on each vine, and the third topping is carried out after the grandman is fruited, and 4-5 fruits are set in each plant. Apply sufficient basal fertilizer and top dressing in time.

Timely control of downy mildew, powdery mildew and aphids in the middle and late stages of growth to maintain plant growth and prevent premature aging.

**The melon has a beautiful appearance, bright color, rich aroma, contains a variety of vitamins and high sugar, is juicy and delicious, sweet and crisp. **Melon is not only delicious and nutritious, but also can tonify and invigorate qi, reduce inflammation and relieve pain, detoxify and kill insects, and also have a good effect on hypertension, coronary heart disease, obesity and so on in the elderly.

It is generally called **melon also known as Shilen** melon, and the academic name is Elizabeth thick-skinned melon.

It's caused by a freeze and a melt, if it's just the epidermis, you can eat it if you remove the skin, but don't eat it if it's like this from the outside to the inside.

The sticky surface of cucumber is a phenomenon of a large number of microorganisms breeding, and it is also a sign of contamination, so please do not eat it.

Summary. Hello, the temperature is too high during the growth period, continuous rain, low temperature, or the carbon dioxide concentration in the greenhouse is too low, which affects the photosynthesis of cucumbers and causes cucumbers to turn yellow; Vegetable farmers do not harvest in time, and improper fertilization and watering lead to insufficient cucumber nutrients; Serious pests and diseases affect the growth of cucumbers.

You bring good things, the temperature is too high during the growth period, continuous rain, low temperature, or the carbon dioxide concentration in the greenhouse is too low, which affects the photosynthesis of cucumbers and causes cucumbers to turn yellow; Vegetable farmers do not harvest in time, and improper fertilization and watering lead to insufficient cucumber nutrients; Diseases and insects are suspected of serious liquid damage, which affects the growth of cucumbers.

These are the reasons why cucumber skins turn yellow.

Nutrient sufficient control is used more

Weather, temperature changes are also the reason why cucumbers turn yellow.

Thank you so much. No, ha.

Hello, has the question of the foundation been clearly answered for you? If you have any new confusion, please feel free to find me again, and I will answer it for you as soon as possible. I wish you all the best!

Can you still eat cucumbers with whitish inside.

Answers. 1.It is best not to continue to eat cucumbers that are whitish on the inside, because the texture and taste of such cucumbers are generally not as good as fresh cucumbers, and they may have spoiled.

2.We can usually wrap the cucumber in paper and seal it in a plastic bag, and then store it in a cool, ventilated place.
