What is the reason why cucumbers have rotten hearts and milky white holes on their bodies?

Hello, cucumber in the process of planting and management, due to the planting density, many years of heavy stubble, partial nitrogen fertilizer, organic fertilizer is not fully rotten, poor ventilation, high humidity, poor drainage, insufficient light and other reasons, coupled with scab, vine blight, bacterial blight and other diseases, often cause cucumber rotten tip. In view of the rotten tips caused by different **, targeted control measures can be taken to promote the growth of cucumbers and improve the yield and quality.

Prevention and control methods. 1. Cultivate strong seedlings and strong seedlings.

After the cucumber seedlings are planted, the new high-lipid film should be sprayed in time, which can effectively prevent water evaporation, isolate the harm of pests and diseases, shorten the seedling delay period, and promote the seedlings to be strong. After the seedlings are slowed, the growth of the seedling roots can be promoted through temperature control and water control measures, and the absorption of nutrients by the roots can be enhanced, so as to promote the growth of melon seedlings.

2. Reasonable cultivation.

After the seedlings are planted, they can be hoeed many times from shallow to deep near the main stem of the seedlings, and the main purpose is to break off the shallow root system of the seedlings, promote the deep rooting of the seedling taproot, and enhance the absorption capacity of the root system and the disease resistance of the plant. At the same time, the weeds in the field are eradicated, the loss of soil nutrients is reduced, the ventilation and ventilation of the field are enhanced, and the occurrence of pests and diseases is reduced. In the process of plant growth, the soil should be cultivated from time to time according to the specific situation, which is conducive to the healthy growth of melon seedlings.

3. Spray fungicides in time.

After the cucumber sits on the melon, in order to prevent the cucumber from rotting the tip, while spraying the growth regulator and nutrient solution, some pesticide fungicides and new high-fat film should be added to disinfect the wound and avoid the direct invasion of germs from the wound, so as to avoid the occurrence of the cucumber rotten tip.

4. Combination of top dressing and micro-fertilizer root irrigation.

In the process of growth, cucumbers should be topdressed in time to provide sufficient nutrients for the growth of plants and improve the yield and quality of melons and fruits. At the same time of top dressing, micro-fertilizer can be used to irrigate roots, such as the use of Ribery Yanwo chelated trace element water-soluble fertilizer, which can promote the better absorption, digestion and release of nitrogen, phosphorus, potassium and various trace elements in the soil, enhance the positive energy of fruit development, improve disease resistance, and prevent and reduce the occurrence of rotten tips.

The reason why cucumbers are rotten.

1. In the summer season, open-field cucumbers are very prone to viral diseases during the solar term, mainly caused by three viruses: cucumber mosaic virus, melon mosaic virus and tobacco mosaic virus.

2. In the process of cucumber growth, it often mixes. Generally, the disease is manifested from the upper young leaves, some appear flowers and leaves, some appear dark green raised wrinkles, uneven, and some produce fern leaves and lobes, and the onset is early, and the plants are dwarf or wilted.

3. The prevention and control should adopt comprehensive control measures based on the selection of disease-resistant varieties or disease-resistant varieties, supplemented by cultivation and disease prevention.

Difference Between White Cucumber and Green Cucumber.

1. Different types: white cucumber and green cucumber are two different types. White cucumber, also known as native cucumber.

As a traditional cucumber variety in the country, people have a very long history of eating white cucumbers. Green cucumbers, also known as cucumbers, are named because of their blue-green appearance. In Guangdong, China, it will be called so.

2. Different taste: white cucumber, that is, local cucumber. This cucumber is thicker and shorter than green cucumbers, and when ripe, it will have a melon pulp, and the color of the skin will change from white to yellow.

White cucumbers can be eaten raw when they are tender, and when ripe, the flesh has a rough texture, and it is best to pickle, dried, or stewed in soup. Green cucumbers, which have always been green from small to large, have a smaller diameter than cucumbers, have a long body shape, and have obvious spikes on the surface, it has a crisp taste and more juice than white cucumbers, so it can be used directly for raw food. In addition to this, stir-frying is also its most common practice.

This must be cucumber worms. That's why it will lead to a bad heart. And the cucumber also has a small hole on it that is full of insect bites, which is a sign of raw insects.

If you put salt in it, it should be sand, and it's okay, and the cucumber is generally rotten, but it's wilted, and you can see it.

Summary. Prevention and control methods of cucumber scab.

l) agricultural control, adhere to the introduction of seeds from disease-free areas and carry out seed disinfection, disinfection methods, can be soaked in warm water at 55 degrees Celsius for 5 minutes, soaked in cold water for 4 hours after removal to promote germination and sowing, can also be used 5o% carbendazim dressing, the dosage is the weight of the seed, and non-melon crops adhere to more than 2 years of rotation, even with sterile soil seedlings, can also be used per square meter 8-lo grams of 5o% carbendazim disinfection bed soil, the production shed is disinfected with sulfur powder before planting, 5oo grams of sulfur powder per mu plus 2-3 kg of sawdust for fumigation. Control the temperature and humidity of the shed (such as water control and humidity) to make it unfavorable to the occurrence of diseases.

2) Pharmaceutical prevention and control, once the onset of the disease should be immediately treated with medication, you can choose to use 5% chlorothalonil dust per mu l kg powder, or use 45% chlorothalonil smoke agent per mu 5oo grams of fumigation, powder spraying should be carried out in the morning before the wind, smoke should be carried out in the evening after the shed is closed. It can also be sprayed with 7o% methyl tobuzin 6oo times, 75% chlorothalonil 5oo times or nemesis 5oo liquid for spray control, spray once every 5-7 days, and spray 2-3 times in a row.

It is better to find an agricultural specialist, work under their guidance, what is going on with something transparent on the cucumber, and there are small holes, what is going on with rotten hearts.

Hello, I have seen your question and am sorting out the answer, please wait a while

Cucumber fat is propylene glycolic acid, which is the reason why we feel a little astringent when we eat cucumbers.

Is it that the leaves of cucumbers are rotten and have small holes in the heart?

The leaves are also rotten, mainly because the cucumbers have grown up, with white latex-like holes, and the cucumbers are rotten and cannot be eaten3

Cucumber scab, the symptoms are the damaged leaves and melon strips, the affected leaves are light yellow-green nearly round small spots at the beginning, and then the lesions become thin and brittle, easy to break and perforate, and there is a yellow halo around the lesions; The melon strips were injured with round or oval locust bi-shaped green spots, and transparent and noisy yellow-brown gelatinous substances overflowed from the lesions.

What kind of medicine. Cucumber scab scab prevention and control method (l) agricultural control, adhere to the introduction of seeds from disease-free areas and carry out seed disinfection, disinfection methods, can be soaked in 55 degrees Celsius warm water for 5 minutes, after taking out in cold water soaked for 4 hours to promote germination and sowing, can also be used 5o% carbendazim seed dressing, the dosage is the weight of seeds, and non-melon crops adhere to more than 2 years of rotation, even with sterile soil seedlings, can also be used per square meter 8-lo grams of 5o% carbendazim disinfection bed soil, the production shed in the height of the planting with sulfur powder smoke disinfection, 5oo grams of sulfur powder per mu plus 2-3 kg of sawdust for fumigation. Control the temperature and humidity of the shed (e.g

water control and humidity reduction), so that it is not conducive to the occurrence of diseases. (2) Pharmaceutical prevention and control, once the onset of the disease should be immediately treated with medication, you can choose to use 5% chlorothalonil dust per mu l kg powder, or use 45% chlorothalonil smoke agent per mu Fan Nianyou 5oo grams of smoke, powder spraying should be carried out in the morning before the wind, smoke should be carried out in the evening after the shed is closed. It can also be sprayed with 7o% methyl tobuzin 6oo times, 75% chlorothalonil 5oo times or nemesis 5oo liquid for spray control, spray once every 5-7 days, and spray 2-3 times in a row.

Cucumber melons have white embroidery on their bodies, which may be powdery mildew. Prevention and control methods, you can refer to the following points.

1. Choose disease-resistant varieties.

In areas where powdery mildew is common, disease-resistant and high-yield varieties should be selected according to local conditions.

2. Create conditions for disease resistance.

Appropriately widen the row spacing and increase the ventilation and light transmission conditions; Increase the application of phosphorus and potassium fertilizers to control plant growth.

3. Environmental fumigation.

Powdery mildew spores scatter and adhere to the space around the diseased plant. It is easy to get sick in greenhouses and greenhouses in autumn and winter, and powdery mildew bacteria are particularly sensitive to "sulfur", so they can be ignited and fumigated with sulfur powder plus sawdust or other accelerants every 100m2, and smoked for 1 day and night, which can kill powdery mildew, and then smoked once every 3 days, and then sown or planted. During the growth period of cucumber, the amount of sulfur powder can be reduced by half, the time can be reduced to 1 night, and then smoked once every 5 7 days, the effect is good.

4. Strengthen field management.

Attention should be paid to improving ventilation and light transmission conditions in shed cultivation, and timely topdressing and spraying of fertile leaf amino acid foliar fertilizer should be focused on open field cultivation to prevent plant growth or premature senescence and enhance plant resistance.

5. Timely spraying for prevention and control.

When the central disease occurs in the field, you can choose to use 1000 times of 50 methyl tobuzin wettable powder or 500 600 times of 75 chlorothalonil wettable powder, spray 1 time every 5 7 days, in addition, 30 dibacterone 1000 times liquid has good control effect, 800 times liquid has the best effect. The alternating use of pesticides can avoid the resistance of powdery mildew, and do not neglect the spraying of the ground when spraying. According to daily experience, spraying Bayleton 4000 times liquid has a good effect, spraying Bayleton 4000 times liquid + chlorothalonil 1000 times liquid has a good effect, and can also treat other fungal diseases that occur at the same time.

6. Do a good job in spraying prevention.

Early prevention of disease, early treatment of disease, starting from the time when the plant is on the shelf and sealed, spray 100 times of 27 high lipid film emulsion regularly or irregularly.
