Why does winter melon rot and why does winter melon rot when it grows on a vine?

Any food will spoil after being left at room temperature for a while. Some are moldy and clumpy, some are rotten and smelly, and some are sour and ......There are three main causes of food spoilage: 1. Microorganisms are at fault.

Microorganisms are everywhere in the environment, and food is easily contaminated by microorganisms during production, processing, transportation, storage, and marketing. As long as the temperature is right, microorganisms will grow and multiply and break down nutrients in food to meet their own needs. At this time, the protein in the food is destroyed, and the food will emit a foul and sour taste, lose its original toughness and elasticity, and the color will also change.

2. The role of enzymes. There are many enzymes in animal food, and under the action of enzymes, the nutrients of the food are broken down into a variety of lower products. The rice and fruit rot that we usually see are because the carbohydrates are broken down by enzymes and fermented.

3. Chemical reactions of food. Fats are easily oxidized, resulting in a series of chemical reactions, and the oxidized fats have a strange smell, such as fat meat will turn from white to yellow. Spoiled food not only changes its appearance, loses its original color, aroma and taste quality, but also reduces its nutritional value, and also contains corresponding toxins that endanger human health.

Prevent decay: After deciding to keep the melon, it is necessary to apply less nitrogen fertilizer and increase phosphorus fertilizer and potassium fertilizer to promote the enrichment and maturity of the winter melon tissue and improve its storage resistance. Stop fertilizing 15-20 days before harvest and reduce watering to reduce the moisture content of winter melon.

Winter melon should be picked at the right time on a sunny day, not on a rainy day.

Care should be taken when picking and handling winter melons to avoid or minimize damage to winter melons. When harvesting, you should hold the melon with your hand to prevent the melon from falling to the ground and rotting. After harvesting, the winter melon is transported back to the storage site in sacks or straw bags.

Choose a cool, dry, and well-ventilated empty room or old warehouse as a storage room, or you can set up a shed under the shade of the field for storage. In the storage room, bamboo poles or pine strips are used to erect multi-layer storage racks, with a length of 2-8m and a width of 50-60cm. Leave a 60-70cm aisle between the racks for shelf operation.

Before storage, soak the winter melon in 75 Tobujin 1200 liquid for 2-3 minutes, dry it and store it on the shelf. Only 1 layer of winter melon is placed in each grid, and it is not suitable to be stacked on top of each other. It is also possible to lay the melon diagonally against the wall so that the stem of the melon is close to the ground, which can also be stored for several months.

During storage, the condition of winter melons should be checked frequently, and rotten melons should be dealt with in time to avoid mutual infection. Winter melon rot mostly starts from the inside, which can be identified by the following methods. The skin of the melon is dark green, and it feels relatively firm to the touch, and it makes a crisp sound when flicked with your fingers; The skin of the rotten melon is pale yellow, and if you press it lightly with your fingers, the skin will sag.

Because of the hot weather, bacteria are prone to formation.

Winter melon will rot when it grows on the vine because it has winter melon soft rot.

The soft rot fungus of winter melon overwinters in the soil with the diseased residues. The following year, it was spread by rainwater, irrigation water and insects, and was invaded by wounds. After the invasion of the pathogen, pectinase is secreted to dissolve the middle colloidal layer, causing the cell to fall apart, causing the water in the cell to overflow and cause decay.

Pruning and pruning on rainy days or when the dew has not dried, or insect injuries are more likely to be serious.

Harmful symptoms: mainly harmful fruits, water-stained at first, and then gradually soft, the diseased part is sunken, the internal tissue is rotten, often due to this disease, the melon strips are broken and fall to the ground, and the diseased melon has a foul smell.

Winter melon soft rot is mainly harmful to the fruit, at first it is water-stained, and then gradually softens, the diseased part is concave, and the internal rot is rotten, often because of the disease, the melon strip is broken and falls to the ground, and the diseased melon has a foul smell. The germ overwinters with the diseased carcass and spreads the following year, invading through wounds.

Why does winter melon get soft rot? How to prevent it? Harmful symptoms: mainly harmful fruits, water-stained at first, and then gradually soft, the diseased part is sunken, the internal tissue is rotten, often due to this disease, the melon strips are broken and fall to the ground, and the diseased melon has a foul smell.

Large winter melon can only be thrown away when it is rotten, which is caused by sclerotinia sclerotinia of winter melon.

During the growth of winter melon, due to the humid environment in which it is located, the bottom is prone to rot, and the plant generally needs ventilated growth conditions.

The phenomenon of bad fruit on the vine may be a physiological disease, and unfavorable conditions such as high temperature, scorching sun, drought, heavy rain, and uneven watering are the main reasons for the bad fruit of winter melon.

It's not that the winter melon will rot when it grows on the vine, in fact, if this winter melon is long, it will be ripe, and it will rot if you don't pick it, which is some common sense we should know.

No, food will spoil if it is not stored properly, and many people think that spoiled food can be eaten after boiling, which is not true. The toxins secreted by bacteria before they enter the human body are very resistant to high temperatures and are not easily destroyed and decomposed. Therefore, this method of using heat and pressure to deal with spoiled food is unscientific, and the spoiled food must be poured out, and it must not be lost because of small things.

In these spoiled foods, some toxins secreted by bacteria are usually produced, which will interfere with the body's metabolism and eventually affect the normal function of human tissues. For example, in rotten fruits, the decocylotoxin produced can paralyze the nerves, and can also affect the normal function of the kidneys and promote premature aging.

What's even more terrifying is that some moldy foods will also produce some carcinogenic toxins, such as aflatoxin, variegated aflatoxin, patulin, red penicillin, b fumonisin, hethoxin, etc. Winter melon is generally cut into chunks**, sometimes the amount bought is too much to eat, and the winter melon is easy to rot after a period of time. Some people will cut off the rotten parts and eat the parts that are not rotten.

In fact, it is wrong to do this, after the winter melon is rotten, the nutrients will be reduced, and some harmful substances will be produced, which cannot be eaten, otherwise it will cause damage to the human digestive system.

Winter melon rots because winter melon contains sufficient water and nutrients, which is suitable for the breeding and reproduction of spoilage bacteria, decomposes the normal components of winter melon, and causes the deterioration of winter melon.

After it is broken, it is best to throw away the rest and do not eat it, because the spoilage bacteria and harmful substances generated in the rotten part will be contaminated into the flesh of the winter melon that is still good in appearance, and it is also harmful to human health after eating, so it is best not to eat.

Ingredients: Winter melon (has been cut, if it is intact and placed in a cool place, it can be kept for a long time without rotting) Tools: plastic wrap, knife Dan defeat.

Operation steps: 1. Cut one winter melon.

2. Take the plastic wrap, cover the winter melon with plastic wrap that has been cut, and cut off the excess with a knife.

3. Smooth the contact surface with your hands, and do not let the air mix inside.

4. Put it in the fresh-keeping layer of the refrigerator, and use this method to keep the mold for 5-7 days, and it should be eaten as soon as possible.

Winter melon will rot when it grows on the vine, it may be that the winter melon has soft rot, and the bad fruit should be removed in time to avoid being infected, and the drug should be applied in time.

How to care for winter melon.

1. Temperature: The most suitable temperature for its development is about 25 degrees, and when it grows into an adult, the temperature needs to be adjusted to 30 degrees, so that its growth state is the best. Because it is not tolerant to low temperatures, the temperature should be controlled well when cultivating in winter, and the temperature will be frostbitten if the temperature is lower than five degrees.

2. Watering: Because its volume is relatively large, so the consumption of water is also very large, if it encounters dry weather, it is necessary to properly supply water, it is best to do it once every other day, if the rain is normal, it is also necessary to do a good job of drainage.

3. Fertilization: During the growth period, its consumption of nutrients is very large, and the nutrients in the soil alone are not enough, so it needs to be properly fertilized.

4. Light: Short days have little demand for light, and it is no exception. Proper light is good for flower bud differentiation, but when it comes to growth, it still needs sufficient light. It's usually about five hours.

1. Remove the gourd, cut the skin of the melon, and clean it with water. Then cut into small squares of cavity silver with a thickness of 2 cm. Don't cut it too thinly, otherwise it will be easy to cook and taste bad.

2. After cutting the winter melon pieces, you need to add one more step, cut the winter melon pieces horizontally with a knife three or four times, and hit a few flower knives, so that the winter melon can be flavored.

3. Prepare the ingredients, cut the chives into chopped green onions, wash the chili peppers, remove the roots, cut them into small pieces, cut the ginger into shredded ginger, and prepare all the ingredients for later use.

4. Add an appropriate amount of cooking oil to the pot, put in the winter melon pieces, fry the winter melon until golden brown on both sides, add the dark soy sauce, and pat it to make the winter melon evenly colored.

5. Add a bowl of water after lusting, stir-fry a few times and cover the pot, simmer until the winter melon becomes soft, add an appropriate amount of salt to reduce the juice over high heat, and after the soup is drained, put it on a plate and sprinkle with chopped green onions.

Winter melon storage will not rot methods:

1. Store in a cool place.

If you can't eat the winter melon after cutting it, you can put the remaining part of the cut winter melon in a ventilated and cool place, which can also be stored for 1-2 days, but it is best to eat it on the same day.

2. Keep the refrigerator fresh.

Uneaten winter melon can be wrapped in plastic wrap and stored in the fresh-keeping layer of the refrigerator, and the preservation time of this method is about 2-3 days.

3. Keep it with plastic wrap.

After the winter melon is cut, there will be a little bit of mucus on the cut surface, at this time, you can use a piece of plastic wrap that is a little larger than the cut surface or a clean white paper of the same size as the cut surface to paste, and touch it tightly with your hands, you can keep it fresh for 3-5 days.

4. Soak and store in rice water.

After peeling and removing the seeds, cut the winter melon into palm-sized pieces, and then cut each piece horizontally and vertically into three knives, do not break the bottom, soak it in rice washing water for 24 hours, and then replace it with cold water and add a little salt to continue soaking. This can be stored for 2-3 days.

5. The white paper is close to the faceted surface.

If you don't have a refrigerator, just take a piece of clean white paper the size of the cut surface of winter melon and stick it on it, and then smooth it with your hands, so that it can be stored for 4 days without spoiling. However, be careful to keep it in a well-ventilated place.

1. Cold storage preservation, winter melon can be stored in cold storage, which is also a more suitable storage method in the world so far. Charcoal maggot disease is one of the common diseases in the storage of winter melon, which is a disease brought into the field, so low temperature is more necessary.

Winter melon storage temperature: 10 15, relative humidity: 70% 85%, freezing point: , chilling temperature: <10. In the above cold storage environment, winter melon can be stored for at least 4 to 6 months.

2. Field storage method. This method is suitable for autumn, on the basis of strengthening the fertilizer and water management in the late field stage, the winter melons that have not yet matured are each mated with wheat straw or licorice, and then covered with wheat straw or hay.

During the process, pay attention to avoid direct sunlight and prevent excessive moisture and decay. By choosing this method, the winter melon can be harvested at a low temperature in winter.

3. Cellaring method. Choose a cool, ventilated and dry cellar or warehouse, after full disinfection, put sleepers and other overhead on the ground, and then put soft and ventilated materials such as hay on top, and place the winter melon on it, pay attention to the state of the winter melon growing in the field.

If the humidity is too high, or the temperature exceeds 30, turn on the exhaust fan or air conditioner to cool down, and avoid the warehouse from direct sunlight.

The methods for preserving winter melons in summer that will not rot are: cold storage preservation method, field storage method, and cellaring method.

1. Cold storage preservation method: put the winter melon in the refrigerator or cold storage for storage. Winter melon storage temperature:

10-15C, Relative Humidity: 70% 85%, Freezing Point: -9C, Chilling Injury Temperature:

10. In the above cold storage environment, winter melon can be stored for at least 4 6 months.

2. Field storage method: the winter melon that has not yet matured, each mated with wheat straw or grass, covered with wheat or hay, pay attention to avoid direct sunlight in the process, and prevent excessive moisture and rot, the selection of this method can delay the ripening of winter melon to harvest at low temperature in winter.

3. Cellaring method: choose a cool, ventilated and dry guest or warehouse, after full disinfection, put wood on the ground, and then pad soft and ventilated materials such as grass on it, and place the winter melon on it, the humidity at room temperature should not be too large, and the temperature should be too high to open the exhaust fan or air conditioner to cool down, and avoid the warehouse from direct sunlight.

The growing environment of winter melon

1. Temperature: Winter melon is temperature-loving and heat-resistant. The suitable temperature for growth and development is 25-30, the appropriate temperature for seed retardation is 28-30, and the minimum temperature for root growth is 12-16, all of which are higher than those of other melon vegetables.

The suitable temperature for pollinating fruit is about 25, and the temperature below 20 is not conducive to fruit development.

2. Sunshine: Winter melon is a short-day crop, and short sunshine and low temperature are conducive to flower bud differentiation, but long sunshine and sufficient light are required throughout the growth period. In the fruiting period, if there is long-term rain and low temperature, flower drop, melon melting and rotten melon will occur.

3. Nutrients: Winter melon has a long growth period, and the vegetative growth of plants and fruit growth and development require enough soil nutrients, and more fertilizer must be applied. Nitrogen fertilizer was mainly used for fertilization, and phosphorus and potassium fertilizers were appropriately combined to enhance the stress resistance of plants and increase the amount of single-fruit seed production.
