How to prevent pumpkins from only blooming and not bearing fruit?

Pumpkin has good cultivation characteristics and strong adaptability to environmental conditions, and is widely cultivated in the world. In recent years, among the best-selling pumpkins on the market, there are often more flowers and fewer melons, which is caused by many factors such as insufficient light, excessive nitrogen fertilizer, and poor pollination. How to sit on melons more, let's briefly introduce it below.

1. Pick the top of the pumpkin at the right time.

According to the needs of pumpkin planting, the vines can be pruned appropriately and the side vines can be left.

Second, the bracket setting.

Set up the bracket in advance, pull the stem to climb the bracket, make sure that the branches do not block each other, and when the pumpkin has reached a certain growth stage, it will enter the flowering period.

3. Pumpkin pollination.

Pumpkins are cross-pollinated and require insects to spread pollen to achieve the effect of fruiting. When it rains, insects can't spread pollen, which can lead to low fruit set in pumpkins. Male flowers are first blooming, and female flowers need to be fertilized when they open.

First, the female flowers that are about to open and ready to be pollinated are covered with melon leaves to prevent the invasion of rain. At 9 o'clock the next morning, the male flowers of the different plants are picked and covered with female flowers. They were removed after three days.

Fourth, pest control.

Pumpkin pests and diseases are more, but also more likely to occur, for the prevention and control of pumpkin pests and diseases, the current advocates of agricultural control, supplemented by chemical control. The main pests include phenol insects, ants, etc. This will seriously affect the yield and quality of pumpkins.

In pest control, targeted chemical agents can be selected for spray control, and the control effect is relatively ideal. The main disease of pumpkin is a viral disease, which will directly affect the growth and development of pumpkin, shorten the growth period, reduce the yield and reduce the quality. Among them, phenol worms are the main vectors of viral diseases, so the prevention and control of viral diseases should be the first priority.

In the case of severe disease, it is necessary to clean up the plants to prevent the spread of the disease. To briefly introduce it, we can inhibit the crazy growth of pumpkin plants, promote the emergence of more female flowers, prevent melon dropping, and improve the melon drop rate.

First of all, when planting, we must choose the soil is more fertile and broad land, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there are small insects, then we must spray insecticides in time. I think that if we can do these things well, we will be able to prevent the pumpkin from blooming but not bearing fruit.

When the pumpkin is growing, the pumpkin should be branched to avoid growing too many branches, resulting in no nutritious fruit, and pollination should be carried out when the pumpkin is blooming, which can prevent the pumpkin from only flowering and not fruiting.

You can fertilize the pumpkin more, pay attention to the growth process of the pumpkin, carefully observe the pumpkin, and prevent and control the diseases that appear in the pumpkin, so as to prevent the pumpkin from only flowering and not bearing fruit.

After the pumpkin blooms, it is necessary to replenish water and nutrition in time to check for harmless insect damage.

There are many reasons why pumpkins do not bloom and do not bear fruit, which are related to nutrients, light, water, and pests and diseases. If it is caused by insufficient nutrients, light or water, the pumpkin needs to be supplemented with water, light or fertilizer. If it is caused by pests and diseases, it is necessary to cut off the diseased branches and leaves of the pumpkin, and spray the pumpkin with relevant chemicals for control.

In the early flowering stage, pumpkins have high requirements for fertilizer and need sufficient fertilizer for their growth. Before flowering, if the pumpkin is deficient in nutrients, the flowers may not develop. If it is caused by insufficient nutrients, it is necessary to apply an appropriate amount of phosphorus and potassium fertilizer to the pumpkin, and sufficient fertilizer is conducive to the opening of flowers.

Pumpkins need plenty of light during and before flowering, which can promote the opening of flowers and prolong the flowering period. Pumpkins do not bloom or bear fruit, possibly due to a lack of light. If the pumpkin does not have enough light, it needs to be given enough light so that it can photosynthesize and accumulate nutrients.

Pumpkins need water during the growth period, and sufficient water can promote the growth of flowers and fruits. During the maintenance period, the pumpkin lacks water, the flowers grow poorly, and they cannot be pollinated in the later stage, which will affect the harvest of the fruit. If the pumpkin lacks water, it needs to be watered in moderation to replenish the water, but after it blooms, the water needs to be controlled.

During the growth period, if the pumpkin is not in the environment or the growth is too poor, it is easy to be attacked by diseases and insects. After the pumpkin is attacked by pests and diseases, the flower buds will be infected by bacteria or eaten by pests, which will affect the opening of the flowers in the later stage. If it is caused by pests and diseases, it is necessary to cut off the leaves of the diseased branches and insects, and then spray them with relevant agents to inhibit them, so that the pumpkin can recover.

Pumpkin only blooms and does not bear fruit may be due to insufficient light, lack of nutrients, insufficient pollen of female flowers or too much growth density, when planting pumpkins to let it receive sufficient light, the growth period to supplement it with sufficient nutrients, melon vines can grow to a certain length when you can build a shed to breed, when the melon vines are cultivated, the melon vines will produce a lot of pumpkins.

1. Insufficient light

Pumpkin is native to Mexico, and when it is cultivated, pumpkin vines will produce a lot of melons What is the reason why pumpkins only bloom and do not bear fruit, pumpkins need to receive sufficient light during the growing period, and if the light is insufficient, it will only bloom and not bear fruit, so it needs to receive sufficient light, and if it is planted in summer, it is still necessary to do a good job of shading.

2. Lack of nutrients

Pumpkin is an annual herbaceous plant, the demand for nutrients is large when growing, and the lack of nutrients will only bloom and not bear fruit. Nitrogen fertilizer should be applied to it after each harvest, and the fertilizer can be diluted with water before fertilization to prevent fertilizer damage.

3. Not enough pollen

Pumpkins generally bear fruit by spreading female pollen, and if the female pollen is not enough, it will only bloom and not bear fruit, so the amount of female pollen can be increased by artificial pollination. Cotton swabs can be used for manual pollination, and it is best to keep the temperature at a level during the pollination process.

4. The density is too large

Pumpkin belongs to the creeping plant, its melon vine will crawl on the ground to grow, if the density of the melon vine is too large, there will be no light opacity, resulting in the melon vine only flowering and not fruiting, then you can build a shed to plant the melon vine on the shed, the light transmittance is good, the melon vine will bear fruit.

1. Too little fertilization: pumpkin will only bloom and not bear fruit when it is malnourished, so it needs to be top-prated with phosphorus and potassium fertilizer. 2. Improper pollination:

Hand-pollinate pumpkins to make them bear fruit quickly. 3. Dense branches: Cut the over-dense branches of the pumpkin to save nutrients.

4. Improper pruning: Cut off the long branches of the pumpkin to concentrate the nutrients on the fruiting branches.

1. Improper fertilization

When pumpkins are not fertilized effectively after flowering, they will not bear fruit. Therefore, it is necessary to do a good job of fertilization measures regularly, mainly phosphorus and potassium fertilizers after flowering, and less nitrogen fertilizers. If too much nitrogen fertilizer is applied, the nutrients are concentrated on the branches and leaves, rather than on the flowers and fruits.

2. Insufficient pollination

When pumpkin pollination is severely insufficient, it will lead to flowering but not fruiting. Pumpkin fruiting is determined by the female flower, so we can do it by artificial pollination, pollinating on each female flower, which can greatly increase the probability of pumpkin fruiting.

3. Dense vines

When the pumpkin vines are dense, the light transmission is relatively poor, and photosynthesis cannot be carried out, which will lead to the phenomenon of only flowering but not fruiting. Therefore, it is necessary to maintain the transparency and light transmission of the plant, and a scaffold can be built during the growth process to increase the fruiting rate.

4. Improper pruning

If pruning is not carried out effectively for a long time, it will only bloom and not bear fruit. Therefore, when the vine grows well, it can be topped. When the vine grows to 2-3 meters, the top bud is removed, so that new vines will grow.
