The young pumpkin fruit turns yellow and falls off, how should farmers deal with this situation?

<> "The suitable temperature for the flowering and setting period of pumpkin is 15-25, and it is easy to have poor pollination in the weather below 15, and higher than 30 will affect the normal development of flowers, so it is necessary to properly carry out artificial temperature control work during the flowering and fruit-setting period. The stem and leaves are high, the fruit can be used as a pumpkin cake, can also be used as an ingredient and feed, eat pumpkin in winter, high sugar content, rich in nutrients, has extremely high medicinal value, has a high evaluation in the market, pumpkin is delicious, but in the planting, is growing vigorously a large number of flowering and fruit setting pumpkins, if the planting management is improper, it will cause a serious phenomenon of falling flowers and fruits. There are three reasons why pumpkins are seriously falling flowers and fruits:

First, the plants are too dense and the ventilation is not good;Second, the vines are long, and they are not properly fertilized and watered.

Here it is necessary for us to first understand the reasons why pumpkins fall flowers and fruits. The first is caused by excessive planting density, which is not conducive to ventilation. The second reason is that too much nitrogen fertilizer is applied, which leads to the excessive growth of difficult vines, and the nutrient supply is insufficient during the flowering and fruiting period and falls for planting, the reason is that before the beginning of summer, the weather is hot, the soil is dry, and the temperature difference between day and night is large, which is not conducive to the survival of pumpkin seedlings.

After planting, the temperature is higher and the rainfall is more, although the pumpkin seedlings can grow quickly, they are easy to breed diseases and pests and cause pumpkin death.

Pumpkin is a very common melon vegetable planted in rural areas, pumpkin tender melon and old melon can be eaten, different periods, the taste is different, but they are all very delicious. Pumpkin is also easy to preserve, suitable for long-distance transportation, can be stored for a long time, and is a common vegetable on farmers' tables. There can be four possible causes of pumpkins falling flowers and fruits:

One is that the planting density is too large, the ventilation and light transmission are not good, or the continuous rainy weather affects the pollination of insects, and the artificial assisted pollination is not timely. Another is to apply too much nitrogen fertilizer, or over-watering pumpkins are suitable for growth at a temperature of 25-30, sudden cooling and heavy rain, resulting in poor pollination of flowers, and there are a lot of falling flowers and melons.

Pumpkin is a plant that likes sunlight, if you want it to produce large fruits, it must be placed in the sun, if it is in the summer high temperature, it also needs to be placed in the sun to breed, but it needs to be watered in time to keep the soil and air moist.

When the pumpkin turns yellow and falls off after fruit set, the pumpkin needs to be pruned properly. First of all, you need to choose scissors with a sharp edge, and then you can use scissors to cut off the branches and leaves on the pumpkin plant that are not growing well or are yellowing and dry, and you also need to cut off the branches and leaves that are too long to help the plant save nutrients.

The reasons why the pumpkin turns yellow when it bears fruit are as follows:1. Lack of nutrients: Pumpkin will bear yellow when it is fertilized too little, and it needs to be applied 1-2 times of fertilizer.

2. Too little watering: When there is no rain and drought, you need to water once a week.

3. Branches and vines: cut off the side branches of the pumpkin that has grown too long and too much to avoid the loss of nutrients.

4. Infected diseases: cut off the branches, leaves and fruits of pumpkin infected diseases in time.

Summary. Put it on a dry floor at home, so it is not easy to break, and it does not take long to turn yellow. However, such pumpkins are not as sweet as pumpkins that naturally turn yellow in the soil.

Pumpkins are not very yellow when they are just picked, how can they turn yellow quickly?

Put it on the dry floor at home, so that it is not easy to break, and it does not turn yellow and is not boring, and the ants are buried for a long time. However, such pumpkins do not naturally turn yellow in the soil, such as pumpkins are sweet.

Put the pumpkin into a plastic bag, tie the mouth, and then put it on the balcony where you can get the sun, and then burn a few small holes with a lit incense or cigarette butt on the plastic bag, and don't burn the pumpkin, five to ten on each bag is enough, turn it over every five days, so that it can fully absorb the sun, twenty days to a month. The idea is to keep warm at night, and it will be faster to cover it with a cotton blanket at night.

If you want to turn yellow, you have to ripen it, and if it is ripe, it will be yellow. There are many ways to ripen it, first, alcohol or wine to ripen at a medium speed. Second, put it together with ripe bananas and apples and persimmons, the speed is very slow.

3. Ripening with ethephon, the speed is fast, but pay attention to the dose, and change the rock according to the instructions with Lu Shu.

Pumpkins need a lot of nitrogen fertilizer when setting fruits, and if there is enough fertilizer and water, then pumpkins will have a lot of fruit set. However, if our fertilizer is not used properly, it will lead to lush branches and leaves and reduce the amount of fruit set, and finally lead to insufficient nutrients for young fruits to grow, and finally there is an early phenomenon of falling off the kernel, so we should pay attention to the fertilizer management during the fruit expansion period in our daily management.

At the same time, it should be necessary to reduce the amount of water used in the irrigation. If there is too much water at this time, it will cause the water to direct all the fertilizer to the branches and leaves, and as a result, the pumpkin will weaken.

Another point is its pest and disease problem, which is the most direct cause of pumpkin growth and falling off, so we must have a certain amount of protection. When the plant with pests and diseases must be treated with the right medicine, whether it is aphids, powdery mildew or gray mold, we must spray the drug as soon as possible. Any plant that has wilted should be pulled out in time to prevent it from spreading to other pumpkins.
