What s the deal with the bad heart of the melon? What s going on with the rotten heart of the greenh

Muskmelon, if left for a long time, will gradually deteriorate from the inside. This is very natural, phenomenon, if the melon you buy is not fresh, or he has been leaving it for a long time, he may have such a situation.

It may be that it has been put for a long time, and when it is not fresh, it is easy to have a bad melon heart, or it may be that the melon is soaked in water and the melon seeds are prone to spoilage.

You are brittle in this muskmelon, and when you were a child, you put aside penicillin with people when you were vaccinated. So when you are ripe, you feel a little bit bad in your heart. That's the drug**, so you should eat less melon.

All the flowers are sprayed with the smell of melon. It's all fake. I think I want to eat less, it's not healthy for the body, so I said.

The flowers themselves are all medicine.

If there is no problem with the contact, it is recommended to check the U disk, and there should be no problems with the general large factories, but not necessarily in some workshops. You can use software to detect the U disk, such as chipgenius (chip detection), mydisktest (check whether to expand capacity, etc.), if there is a problem, it can be mass-produced, but what the final state will be depends on RP.

Now the melons are sprayed, and if there is too much medicine, the heart will be bad.

Most of the reasons for the appearance of black hearts in melons are caused by calcium deficiency. After the melon blooms, it has consumed a lot of nutrients, and if there is a lack of calcium and other nutrients, it will seriously affect the normal growth and development of the fruit. Timely foliar supplementation of calcium fertilizers such as calcium sugar alcohol, calcium chloride, and calcium superphosphate.

When the young fruit eggs are large, 50 kg of superphosphate is applied with fertilizer.

Melon rot is a melon disease, which is a wilt disease, which will seriously cause the death of a large number of melon fields. It is a parasitic systemic disease caused by soil (nutrient solution) infection and invasion of vascular bundles from roots and rhizomes. The typical symptoms of the disease are wilting, rotten seedlings, and melon growth can occur during the whole growth period, but the disease is most severe from vine extraction to fruiting stage.

The control measures are the use of water-soluble medium and micro fertilizer seedlings to produce micro-element fertilizer, which can supplement the problem of insufficient soil nutrients caused by heavy stubble, supplement zinc, manganese, silicon, boron and other elements, and can be sprayed, flushed, and drip irrigated seedlings before flowering, young fruit stage, and fruit expansion period, so as to thicken the melon pedicle, strengthen the amount of nutrient delivery, improve the disease resistance of the plant, promote the rapid development of the melon body, juicy and delicious, and improve the fruit and quality of the melon. The main pathogenic bacteria of melon rotten melon are fungi and bacteria.

The fungal diseases that cause rotten melon are: blight, sclerotinia sclerotinia disease, anthracnose, vine blight, scab disease, etc. These pathogens are able to survive on seeds, soils, and plant disease residues. If the temperature and humidity conditions are suitable, it will propagate in large quantities and spread and infect the leaves and fruit surfaces of plants.

The main bacterial diseases that cause melon rot are: bacterial fruit rot and bacterial horn spot. These pathogenic bacteria can overwinter on the surface of seeds, soil, and plant disease residues.

It is transmitted through rainwater, insects and agricultural operations, infected through wounds and natural pores, and is seriously affected in 22-28 when the external environment is humid, especially bacterial fruit rot has become the first enemy of melon production.

The main pathogen that causes melon rot is bacteria. The main reason why it is difficult to control is that bacteria can infect melon skin from the outside in. The main diseases that cause melon rot are:

1. Melon bacterial fruit spot disease.

It mainly harms leaves and fruits. The harmful symptoms on the leaves are similar to bacterial horn spots, all of which are horn spots, and they are shiny on the back and form white bacterial pus, and the color of the lesions is yellowish and white, but the bacterial fruit spot lesions can develop along the leaf veins.

The infecting fruit is initially on the skin of the melon, and then expands inward, causing the melon to rot. On the fruit surface of the melon facing upward, it is a small yellow spot like a water stain at first, and then it turns brown, depression, and cracks in the later stage.

2. Bacterial soft rot of melon.

It mostly invades from physiological cracks or wounds, and is a dark green or dark green water-stained lesion at first, and then turns yellow-brown, and the fruit is soft rot inside, and has the smell of rotten eggs.

Other bacterial diseases, such as bacterial leaf spot and bacterial horn spot, can cause corresponding melon rot.

Prevention and control methods: foliar spray can choose agents: copper ren, quilinone, chlorobromoisocyanuric acid, mesomycin, etc.

The fruits and vegetables in the greenhouse are all out-of-season vegetables and fruits.

1. The reason for rotten melons.

1.Rotten melons caused by fungi, bacteria, and diseases. The fungal diseases that cause melon rot are:

Melon blight, sclerotinia sclerotinia disease, anthracnose, vine blight, scab, etc. These pathogenic bacteria can survive on seeds, soil, and diseased plant residues, and are mainly spread by air currents, and when the external environment is humid, they will be infected again and occur in a large area. The bacterial diseases that cause melon rot mainly include melon bacterial horn spot and soft rot.

These pathogenic bacteria can attach to the surface of seeds, soil, and diseased plant residues for overwintering, spread through rain, insects and agricultural operations, and infect through wounds and natural pores, and become seriously ill when the relative humidity of the air is high in 22 25.

2.Due to years of heavy cropping, the number of pathogenic bacteria in the field is large, and the planting technology of melon farmers cannot adapt to the rotten melon caused by this change. Mainly:

1) Do not pay attention to disinfection and sterilization. (2) Improper cultivation technology: planting too densely, poor ventilation and light transmission; Or only pay attention to the growth of the aboveground part, water too much and too often after the seedlings are planted, ignore the root growth, or apply nitrogen fertilizer partially, resulting in excessive plant growth and decreased disease resistance, which provides a favorable environment for the growth of pathogens.

3) Improper preventive and treatment measures and improper medication aggravate the occurrence of diseases.

2. Prevention and control measures.

1.Destroy pathogenic bacteria. After harvesting, bury or incinerate the diseased remains in a timely manner.

2.Cut off the transmission of germs. Before sowing, the seeds should be dried, warmed or soaked in pesticides; Nutrient soil is disinfected to prevent germs from entering or cross-infection.

3.Improve the disease resistance of melons. Select disease-resistant varieties, cultivate strong seedlings, reasonable planting density, and improve the disease resistance of plants. Pay attention to the choice of watering time to maintain a relatively low humidity environment to prevent the rapid reproduction of germs and cause disease epidemics.

4.Rational use of pesticides for prevention and control. As a precaution, if pollination with Parachloride, add a few drops of agricultural streptomycin to the aqueous solution; After irrigation, the humidity in the shed is high, and the protective fungicide is sprayed in time for prevention.

Of course, it is best not to spray pesticides during the pollination period or within 10 days thereafter to avoid damaging the young fruits. In the middle and late stages of plant growth and even cloudy and rainy days, the use of aerosols and dust agents is preferred.

Summary. A normal phenomenon during growth. When the melon is ripe, the melon pulp will turn into water, which is a normal phenomenon in the process of melon growth, but if it exceeds the growth cycle of the melon itself, it proves that the melon will be damaged.

The red liquid that comes out of the growing melon is the liquid of the rotten leaves that have been exposed to impact or damage.

What is the reason for the melon to turn into water when the melon is ripe?

A normal phenomenon during growth. When the melon is ripe, the melon pulp will turn into water, which is a normal phenomenon in the process of melon growth, but if it exceeds the growth cycle of the melon itself, it proves that the melon will be damaged. The red liquid that comes out of the growing melon is the liquid of the rotten leaves that have been exposed to impact or damage.

What to do with the black inside of the melon now.

The surface is smooth, and the water inside is mostly black.

Can you still eat it? There is a black block in the melon pulp to cause vine blight, also known as "black rot neck, mainly occurs in the rainy season in the open field, stems, leaves, melons and tendrils and other upper parts are damaged, and do not harm the roots. The stem disease causes the seedling to die, but the vascular bundles do not change color, which is different from Fusarium wilt.

The stems are mostly susceptible at the base of the stem and nodes, and the oil-soaked elliptical lesions in the diseased parts are initially white, gelatinous, and dense with small black spots.

It's best not to eat it anymore, although the bad place is only visible to the naked eye, but the melon that is a little bad has actually been infected by bacteria, so it should not be eaten again.

It's not too dark to turn blue after opening.

Don't throw it away. Is it okay to feed cattle and sheep?

OK. I grow it myself, and some people say they water it too much.

It's not black cripple.

Summary. A melon can keep 4-6 melons according to the situation, but there are many varieties of melons, so the number of melons is also different. If it is an early-maturing small-fruited variety, 1-2 melons can be left for single vine pruning, and 2-4 melons can be left for double vine pruning.

If it is a medium-late ripening large-fruited variety, you can leave 1-2 melons. When Elizabeth melons are left with melons, it is more appropriate to keep 2 melons in one melon, and 2-3 melons can be left in one Emerald melon.

Precautions for melon planting.

Urea can no longer be used for watering: the nitrogen contained in urea is divided into amides, and the amide nitrogen is converted into ammonium carbonate through the urease function secreted by soil microorganisms before it can be absorbed by vegetables, or adsorbed and stored by the soil. For example, watering with urea will cause loss, so whether you use urea as base fertilizer or top dressing, you need to make it fully transformed within 5 to 7 days after application before watering to avoid losses.

Can not apply ammonium sulfate multiple times: in the acidic soil or calcareous melon field, if the ammonium sulfate is applied multiple times, the acidic soil will become more acidic, and the calcareous soil will produce compaction, which will seriously affect the normal growth of melon.

What's going on with the melon bad Tang.

Muskmelon is a nutritious food, containing a lot of water, sugars, it is easy to be polluted by bacteria, and it is not good for the body after eating, therefore, it is not suitable to eat rotten melon, some melons look only a little rotten, in fact, the inside has been polluted by bacteria, but it has not spread, and such melons should not be eaten again.

I knew I couldn't eat it, I just wanted to ask what was the reason for the bad Tang.

A melon can keep 4-6 melons according to the situation, but there are many varieties of melons, so the number of melons is also different. If it is an early-maturing small-fruited variety, 1-2 melons can be left for single vine pruning, and 2-4 melons can be left for double vine pruning. If it is a medium-late ripening large-fruited variety, you can leave 1-2 melons.

When Elizabeth melons are left with melons, it is more appropriate to keep 2 melons in one melon, and 2-3 melons can be left in one Emerald melon. Precautions for melon planting can no longer be watered after using urea: the nitrogen contained in urea is divided into amides, and the amide nitrogen is converted into ammonium carbonate through the urease function secreted by soil microorganisms before it can be absorbed by vegetables, or adsorbed and stored by the soil.

For example, watering with urea will cause loss, so whether you use urea as base fertilizer or top dressing, you need to make it fully transformed within 5 to 7 days after application before watering to avoid losses. Can not apply ammonium sulfate multiple times: in the acidic soil or calcareous melon field, if the ammonium sulfate is applied multiple times, the acidic soil will become more acidic, and the calcareous soil will produce compaction, which will seriously affect the normal growth of melon.

It's just too ripe, or if it cracks, it will be bad.

1. Unbalanced water management (sudden increase in moisture), large fluctuations in temperature, improper fertilization, excessive nitrogen, and calcium deficiency may lead to the problem of melon cracking. We can't change climate change, but water management and fertilization management should be well controlled, control the use of nitrogen, pay attention to calcium supplementation, believe that melon and young melons begin to continue to expand, underground pouring or drip irrigation micro root supplement calcium + energy + impulse magnesium, at the same time leaf spray micro supplement cover force + boron force, calcium supplementation is sufficient, can improve peel hardness and toughness, prevent and reduce cracked melon, improve melon quality.

21. There is a problem of too much nitrogen fertilizer and no potassium fertilizer in fertilization. Muskmelon needs a balance of nitrogen and potassium, which can promote the synthesis and transportation of sugar. According to the analysis of fertilization period, the peak of nitrogen and potassium absorption in muskmelon was half a month after fruit set, which required the top dressing to be applied after fruit set, but the top dressing in this case only focused on nitrogen fertilizer.

Regardless of basal fertilizer and top dressing, only urea is applied without potassium, and the nitrogen and potassium are unbalanced, resulting in a melon taste that is not sweet.

2. In the case of excessive nitrogen fertilizer, irrigation water and rainwater are added. Sufficient moisture** makes the melon expand too fast, causing some of the fruit to crack.

3. During the swelling period of melon fruit, after the nitrogen and water are sufficient, there will be an imbalance of large, medium and trace elements such as phosphorus, calcium and boron, resulting in a decrease in the quality of the melon.

3. In view of the above situation, it is recommended to increase potassium fertilizer when applying basal fertilizer to melon, and potassium fertilizer varieties can be potassium sulfate or potassium chloride. The application rate of potassium fertilizer per mu is 10 15 kg. At the same time, half of the urea amount is subtracted from the base fertilizer.

Top dressing of nitrogen and potassium fertilizer in the first top dressing, addition of 5 to 6 kg of potassium fertilizer in urea. In terms of water management, the amount of irrigation should be properly controlled, and small water should be watered frequently instead of large floods. In addition, during the vigorous growth period of fruits, a mixture of potassium dihydrogen phosphate and borax was sprayed twice on the foliar surface.

What's going on with the rotten heart of the greenhouse melon? 、

Hello, the manifestation of the rotten heart of the greenhouse melon is that the ** part of the melon and fruit is concave and low-lying, and the skin surface of the melon and fruit is relatively flat. The reasons for its rotten heart may include the following aspects:1

Normal temperature or low temperature is too low: low temperature during the growth of melons and fruits is easy to cause the conversion of intracellular water into frozen water, and the water in melon and fruit tissues is difficult to flow, resulting in heart rot. 2.

Improper fertilization: During the growth of melons and fruits, the content of inorganic elements in the soil is unbalanced, which will have a great impact on the growth and development of greenhouse melons. If a single fertilization is carried out according to one fertilizer in the morning for a long time, it may cause the phenomenon of rotten hearts.

3.Improper irrigation: Greenhouse melons need to be applied with sufficient water to maintain growth and development, but excessive irrigation or improper irrigation can also cause rotten hearts, because too much water will cause the center of the melon to become loose and sunken.

4Pests and diseases: If the greenhouse melon is attacked by fungi, bacteria or insect pests, it may cause the internal tissues of the melon and fruit to soften, resulting in heart rot.

In order to avoid the phenomenon of rotten melons in greenhouses, it is recommended to manage them in time, maintain balanced fertilization, reasonable irrigation and control of pests and diseases. For melons and fruits that have rotten hearts, it is recommended to cut them in time to ensure normal growth and development.
