Pumpkins have begun to bloom, but the flowers and fruits are serious, how to prevent it?

Pumpkin does not have high requirements for the planting environment, the planting technology is relatively simple, the most important thing is that it is easy to store in winter, usually put a few pieces of pumpkin directly in the pot of cooking sorghum rice, and then some small pickles when eating, not to mention how delicious it is, eat the remaining pumpkin seeds to wash and dry, enlarge the pot and fry for a few minutes, it is a rare leisure snack, the elderly and children are particularly fond of eating.

So in my hometown, many families will plant a few pumpkin seeds on the edge of the yard, and then pick the pumpkin in the autumn and put it in the cellar to eat in the winter. During the pumpkin planting process, we will also encounter the problem of falling flowers and fruits, which is mainly related to changes in the external environment, as long as we can pay attention to the following points, it is very simple to have a good harvest.

1.The suitable temperature of pumpkin flowering and setting period 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 carry out artificial temperature control work appropriately in the flowering and fruit-setting period.

2.Pumpkin is the same plant of different flowers, the flowers are born in the leaf axils, if the flowering period catches up with the rainy weather, there is no insect to help pollination, it will lead to unsuccessful pollination, so in this case it is necessary to manually pollinate to help it set fruit smoothly.

3.Pumpkin has high requirements for light during the melon-bearing period, and if it encounters weak light and high temperature, it is easy to produce melons, so when the pumpkin just sets fruit, it is necessary to reasonably repair the branches and leaves, especially the excess light blocking should be removed in time.

4.The root system of pumpkin is very strong, so it can grow well in sandy soil or clay soil, but in the case of excessive use of nitrogen fertilizer, it is easy to cause stem and leaf growth, resulting in flower and fruit drop and disease spread, so nitrogen, phosphorus and potassium should be used together when fertilizing.

5.The main reason is that the first developed melon gives priority to the nutrients, and the later flowers will turn into melons due to insufficient nutrients, so we should harvest the first pumpkin if necessary to ensure the normal melon after the back.

To sum up, compared with other vegetable plants, pumpkin is still very easy to flower and set fruit in addition to extreme weather, in addition to combing the overly dense branches and leaves in time, it basically does not need to be taken care of too much. The above are some of the views of scientific vegetable planting, I hope it will be of reference value to you.

Some nutrients can be used. Fertilize more and water more. These are great solutions, and they all work very quickly.

It is very likely that the plant has pests and diseases, and the plant-specific insecticide should be sprayed evenly on the plant leaves in a timely manner, and it should not be watered during the medication, otherwise there is no effect. It can also be caused by excessive fertilizer application.

Pumpkins wilt after fruiting may be caused by improper watering, and pumpkins need to be watered immediately when the soil is dry when they are farmed daily. Long-term failure to fertilize the pumpkin during the growth process will also cause the pumpkin to wilt after fruiting, so during the pumpkin growth period, it is necessary to apply a well-rotted organic fertilizer every half a month to supplement nutrition.

Pumpkins wilt after flowering and fruiting can be caused by improper watering. Pumpkin is suitable for growing in a humid environment, and too little watering makes the pumpkin grow in an arid environment for a long time, and the fruit will not be supplied with water, and it will wilt. Therefore, during the growth period of pumpkin, after finding that the soil is dry and whitish, it is necessary to water and moisturize in time.

Improper fertilization during pumpkin farming can also lead to wilting after flowering. Applying undiluted fertilizer or not fertilizing the pumpkin for a long time will cause the pumpkin to grow poorly, resulting in a lack of nutrients in the fruit, resulting in a falling condition. Therefore, during the growth period of pumpkin, it is necessary to apply the rotted organic fertilizer every half a month to supplement nutrition.

Pumpkin wilting may also be caused by excessive planting density, pumpkin is a vine plant, if planted too densely, it will affect the ventilation and air permeability between the branches and leaves, so that the pumpkin has branches and leaves wilted and lost fruits. Therefore, when planting pumpkins, it is necessary to keep the plant spacing between meters, and the row spacing should be controlled between meters to ensure the ventilation of the environment.

Pumpkins generally bear fruit in summer and autumn every year, during which the temperature is higher and the humidity is high, which is easy to breed bacteria, causing pumpkins to be infected with gray mold, yellow leaves and fruit drops. Therefore, when cultivating pumpkins, it is necessary to regularly observe its growth state, prune off the diseased leaves in time, and spray carbendazim or chlorothalonil.

1. If the pumpkin is not picked at the top, it will always have only one vine growing, so in order to improve the yield of pumpkin and prevent the phenomenon of only flowering and not bearing melon, it is necessary to carry out the top treatment, generally when the melon vine grows to two or three meters, the top of the melon vine will be removed, generally three to five days later, it will grow a few new branches, and finally it will bloom and bear melons, and then wait until the branches grow to a certain extent, and then operate as usual, slowly become the new main vine from the branches, and then bloom and bear melons from the new melon vines, and so on. 2. Build a shed in time In many places in the countryside, the planting of pumpkins is basically crawling on the ground to grow, and the density of melon vines will be relatively large when growing on the ground, all of them are piled together, and the light transmittance is very poor, so it leads to insufficient light and cannot carry out photosynthesis, and finally this phenomenon of not forming melons, so when the seedlings grow to two or three meters, it is necessary to build some shelves for it, so that it grows along the shelves, and the light and ventilation are enhanced to improve the melon setting rate. 3. Prevent the head of the melon from growing in the process of changing the growth of the pumpkin vine can not let it grow seedlings, because in this way it will absorb a lot of nutrients and only focus on the growth of the seedlings and forget to bear melons, so when the melon seedlings grow to a certain extent, we must take action.

What are the causes of pumpkins that are prone to flower and fruit drop? How can I prevent it? The early-maturing varieties of pumpkins have pistils that bloom first and are not pollinated by stamens, that is, the female and stamens have not been encountered.

Early blooming, low temperature, poor pistil development, stunted growth of pollen tubes, poor insemination. Excessive base fertilizer and rainfall caused the growth of greedy green, and the stems, leaves, main and side vines were more than the fruit growth and development, and the nutrient elements were insufficient during the fruiting period, resulting in flower and fruit drop. Under the premise of planting pumpkin, everyone must pay attention to the planting density, if the density is too large, it will not only affect the permeability between the leaves of the pumpkin, but also cause the green plants to earn fertilizer between each other.

Therefore, we must arrange the planting spacing reasonably.

Pumpkin is a charm especially in the weak food crops, his underground stems are more developed than others, many underground stems are guaranteed to be tens of meters of soil resources in many aspects, which also leads to the growth of ground melon seedlings is very sufficient. If the pumpkin is planted in a dense way, it will lead to dense ventilation between each other, which in this kind of nature, it is also very easy to cause the flowering and fruit loss of the pumpkin. Some pumpkins were planted early, the temperature rose slowly, the growth and development of pistils were not good, the growth rate of stamen pollen tubes could not keep up, the expected effect of pollination was poor, and the success rate of the results was low. It is not scientific to use fertilizer.

The amount of base fertilizer is too much, or it is <> even on rainy days

Pumpkin seedlings are greedy and vigorous in the early stage, and lack of vitamin A in the second half. Special weather. Pumpkin is a cross-pollinated green plant, and if the flowering period encounters even rainy temperature, pollination will not be able to carry out deeply, and it will produce flower and fruit drop; On the premise of planting pumpkins, it is necessary to avoid agglomeration planting, and must be reasonably scarce and evenly planted, how to avoid the difficulties caused by too dense green plants from the source. Secondly, after the difficulties have already occurred, we can thin the vines for the watermelon, knock off the branches and some vines that are not tightened, which can improve the problem of falling flowers and fruits caused by too dense green plants.

Too much luxuriant and no high-quality indoor ventilation indoor air: pumpkin growth period, especially under the premise of flowers in full bloom, flowering and fruiting, is the need for sufficient light, there is also a certain amount of indoor ventilation indoor air, can be reasonable blooming, flowering and fruiting, if it is too much luxuriant branches, in the dense and unventilated growth and development of the ecological environment, it is very easy to produce due to air circulation, in the hot season, it is easy to produce poor flowering and fruiting, from small fruits slowly rot, exposed, to do a good job of proper combing of stems, leaves, to give a high-quality ecological environment for growth and development.

It could be too much watering, or it could be the improper use of fertilizer, or it could be that there are not enough nutrients. It is necessary to choose excellent varieties for planting, and also to supplement trace elements in time, and never have too much stagnant water.

In the early-maturing varieties of pumpkin, the female flowers bloom first, and there is no male flower pollination, so there will be no female and male flowering periods, resulting in the inability to pollinate normally. Flowering is early, the temperature is lower, the female flowers are poorly developed, the pollen tube grows slowly, and pollination is poor. When the main vine is stretched to 12 nodes, there are still no female flowers, at this time, it is necessary to promote the transformation of vegetative growth to reproductive growth by weakening the apical dominance.

There are many methods, one is to change the head, the main vine does not bear fruit, but cut off the main vine before the leaf node with the lowest part of the main vine forward, the closer the sub-vine is to the root, the better, and change the main vine to the sub-vine melon; Or carry out a deep tillage and break the roots one step. Because there are too many female flowers, you can properly thin some of the flowers and fruits.

It may be that the rainfall is too much, or it may be that the water in the soil is too large, which may be related to the amount of fertilizer used. It must be fertilized scientifically, watered scientifically, and the soil must not be too dry or too wet.

The main reason for the serious flowering and fruit drop of pumpkin is that the imbalance of water and fertilizer, that is, the improper control of fertilizer and water applied to pumpkin vines, leads to a large number of pumpkin flower and fruit drops. Especially during the flowering period of pumpkins, the pumpkin vines grow very vigorously at this time, and the vines reproduce much faster than the required nutrient rate. At this time, improper watering and fertilization will cause vines, stems and leaves to overgrow and compete for nutrients, so that flowers and fruits lose nutrients.

There is also the pumpkin planted too densely in the field, the field and the plant between the formation of a closed environment, due to poor ventilation resulting in pumpkin flower and fruit drop, pumpkin is generally suitable for growth of 26 to 35 degrees Celsius, if the temperature change is relatively large, it will make the flowers of the melon vine pollinate poorly, but also lead to a large number of pumpkin flowers and melon fruits fall.

Regarding the prevention and control measures of pumpkin flower and fruit fall, it is necessary to control the fertilizer and water during the flowering and fruiting period of the pumpkin, and water and fertilize the pumpkin in a small amount and many times, so that the fertilizer and water management will be more stable. If the vines and leaves are too dense, they need to be pruned to make room for the main vine of the pumpkin to grow and prevent the phenomenon of falling flowers and fruits. During the pollination period of pumpkin, if there is wind and rain during the flowering period, it will be more difficult to pollinate normally, which will affect the normal growth of pumpkin, and will also lead to more obvious flower and fruit drop.

If the pumpkin has a stable nutrition and a good reproductive environment, it can develop better and prevent flower and fruit dropping. However, when pumpkin is rich in nutrients and does not have female flowers, it is necessary to weaken the dominance of the top flowers and fruits to promote reproductive growth. Secondly, for the pumpkin vine, it is necessary to manage a reasonable number of flowers, if there are too many female flowers and too few female flowers cause flower and fruit drop, you can remove some flowers and fruits.

The most effective measure to prevent flower and fruit drop is to carry out manual intervention, which can be selected to be manually pollinated between 7 am and 10 am, which can effectively reduce the phenomenon of flower drop and fruit drop in the case of artificial pollination.

It may be that the outside temperature is not well controlled, if the outside temperature is too high, it has exceeded 35 degrees, then it may cause the pumpkin to not be able to bloom normally.

Pumpkins may be poorly pollinated, with a large number of flowers and melons falling. Water and fertilizer are unbalanced, plants are too dense, and ventilation and lighting are poor.

Pumpkin is a creeping plant that can grow extraordinarily long and is often cultivated in rural areas. Pumpkins can be eaten at different stages of growth, for example, when they are more tender and early, they can be used for stir-frying or stir-frying meat, and when they are ripe, they can turn yellow, and they can also be used to make pumpkin pie or steamed pumpkin. Pumpkin prefers the cool and humid climate in the process of growth, so it is very easy to cultivate, but when the pumpkin is growing, if it has already flowered, but the phenomenon of falling flowers and fruits is very serious, it means that the variety of pumpkin is not good or the pollination is poor, and the planting density is too large.

In the process of planting pumpkins, the variety of pumpkin is very critical, some varieties of pumpkin grow early, so the female flowers may bloom earlier, but at this time the male flowers have not yet bloomed, so they cannot be pollinated normally. When the male and female flowers are not in full bloom at the same time, they cannot be pollinated properly, so the pumpkin will fall flowers. Some pumpkins bloom early, but the local temperature is relatively low, and the female flowers will also be stunted, and then trapped by the phenomenon of land and air disasters.

When the pumpkin is pollinating or during the development period, if the weather is bad and it is always rainy and rainy, then the damage will be very abnormal, so it will also affect the normal flowering and fruiting of the pumpkin, and the phenomenon of falling flowers is also quite obvious. Another very important reason, which many people do not notice, is that the pumpkin is not fertilized in the process of growing. Phosphate fertilizer, potassium fertilizer, nitrogen fertilizer, the ratio of these three fertilizers is not very suitable, for example, if nitrogen fertilizer is used excessively, or if there is a lot of rain in the recent weather, it will cause the pumpkin to turn green.

The leaves of the pumpkin are more lush than the fruits, and the flowers and fruits are not nutritious, so they will fall flowers and fruits. <>

When pumpkin amur is planted, if the density between the two plants is relatively large, then the air permeability is also relatively poor, and the two pumpkins will compete with each other for nutrients, and the leaves and vines are too dense, and there will also be the phenomenon of falling flowers and fruits. This situation is also easier to deal with, you can directly take a pair of scissors to cut off the leaves that are too dense, and make some space for the pumpkin to grow normally, which can reduce the phenomenon of falling flowers and fruits.
