The small number of cucumber fruits affects the economic benefits, what is the reason for the low nu

Now, when the cucumbers bloom and bear melons, the cucumbers in my vegetable garden have already sat on the cucumbers, and it is estimated that it will not be long before you can eat fresh cucumbers. During this time, we should pay attention to the management of cucumbers, and do not have cucumbers that can't sit on the melon. Recently, because of the lack of rain, we should pay attention to the problem of cucumber drought resistance, as well as some bad conditions caused by drought.

When cucumbers enter the flowering and pollination period, we must be careful not to let cucumbers be subject to drought. When cucumber seedlings are very dry, it is easy to have poor pollination of cucumber flowers. At this time, there are two situations:

1. Although the pollination of cucumber flowers has been completed, the pollination effect is not very good due to the impact of drought. In this case, even if the cucumber bears melons, because of poor pollination, most of the cucumbers that grow are curved, or one is thick and the other is thin. 2. Because of the poor pollination of cucumber flowers, the young melons can't sit directly, and they directly turn into melons.

This is the poor pollination of cucumbers caused by drought, and in the rainy season, because after continuous rain, the rain will cause the pollen on the flowers, which will affect the pollination effect of the female cucumber flowers. Moreover, after continuous rain, cucumber flowers, which are pollinated by insect vectors, will also lead to many flowers due to the lack of insect pollination, but they cannot sit on cucumbers.

In fact, in the continuous rainy weather, it is easy to ignore a problem, that is, because the continuous rain is very good, coupled with the previous base fertilizer is relatively sufficient, it leads to the rapid growth of cucumber branches and leaves. Originally, the growth of cucumber plants was basically balanced, and even when it was changing to even growth, because of the abundant rain, the vegetative growth of cucumbers took the upper hand, and the reproductive growth was inhibited. At this time, the branches and leaves absorb a lot of nutrients, which leads to the lack of sufficient nutrient supply for flowers and young melons, which leads to the fact that although there are many flowers, they cannot sit on the melon.

In such a situation, what can we do to avoid these problems?

First, to address the problem of drought. When pollinating cucumbers, we should avoid drought in cucumbers, but we should not water too much, which will affect pollination and sitting melons due to sufficient water and fertilizer. At this time, we can not flood the watering when watering, and it is better to water semi-dry and semi-wet.

Second, for the problem of pollination in rainy days. When it rains continuously, we need to clean the ditch in time to avoid water accumulation. After the rain, even if the soil is loosened by tillage, the soil moisture is reduced. When insect pollination is affected in rainy days, we can improve the pollination effect by manual pollination.

Generally, the small number of cucumbers is caused by insufficient water and fertilizer. Cucumbers like water and fertilizer, so we must pay attention to the quality of water and fertilizer in the planting process, so as to ensure the yield and quality.

First, the watering is not timely, second, the fertilizer is too little, the third step is ventilation, the fourth is not enough sunlight, the fifth is not timely removal of weeds in the field, and the sixth is not done to prevent pests and diseases.

It may be because the cucumber is malnourished, you fertilize a little less, and it's possible that the roots are blistered.

It may be because cucumbers don't get enough light during the growing period, so the number of fruits is small.

1. Spray ethephon.

When cucumber seedlings have 2 true leaves, spray 200 mg kg of ethephon solution, and spray again once after 10 days, which can increase the proportion of female flowers, promote early fruiting, and prepare for more melons.

2. Artificial emasculation.

When the cucumber flowers have just formed, when the male flowers are found, 90% of all the male flowers are removed, leaving only 10% of the male flowers, and they are picked every three or five days, so that the nutrients of the plants in the ruler can be collected, and the female flowers are grown, so as to promote the rate of melon sitting and increase the yield of cucumbers.

3. Artificially assisted pollination.

After the cucumber blooms, pick the male flowers and wipe them lightly on the stigma of the female flowers, which can effectively reduce the falling melon, crooked melon and gourd melon, and improve the melon sitting rate. Artificially assisted pollination should be carried out when male and female flowers are just open.

In order to improve the income of cucumbers, it is necessary to cultivate excellent cucumber varieties, pay attention to reasonable field management, and pay attention to fertilization and watering. Choose a more fertile soil for planting.

Try to water as much as possible, and you can also lose those bad leaves. Animal manure is used because animal manure is very nutritious.

Now this season is the last growth period of open-air cucumbers, flowering and fruiting on nutrient requirements are also increasing, cucumbers appear small head phenomenon is not only caused by the lack of various elements, it is related to the nutrient management of growers, pesticide use and pests and diseases, including cucumber deformed melons are also directly related to these factors. Specifically, we analyze the following situation.

First, the pesticide is used too frequently and the amount of pesticides used during the planting of cucumbers, mainly fungicides, insecticides, etc., the duration of these pesticides is generally 1-2 weeks, the shortest is 3-5 days, if cucumbers are frequently sprayed with these pesticides, it is bound to cause pesticide damage, directly affect the normal body shape of cucumbers, and then appear deformed fruits.

Second, the problem of fertilization in cucumber planting cucumber planting process is too much chemical fertilizer, which will directly cause the cucumber to appear deformed small head, mostly because cucumber in the growth period, the use of too many macro elements and trace elements, if the use of these chemical fertilizers is improper, it will cause the fertility of the soil to decline, if you eat too much, it will directly cause damage to the cucumber, and the deformed melon fruit will appear.

In addition, cucumber diseases and pests will also directly cause deformed melons, such as common powdery mildew, leaf wilt, double eyebrows and other diseases, which will cause cucumbers to fail to grow normally, and then affect the growth and appearance of cucumbers. These are the main reasons that directly lead to the small head of cucumbers.

The general principle of preventing cucumber deformity is to carry out dense planting reasonably, remove the lower yellow leaves in time, increase the irradiation of sunlight, enhance the photosynthesis of cucumbers, increase the organic fertilizer of farmers, apply potassium fertilizer and boron fertilizer, and most importantly, not carry out flood irrigation, which can effectively prevent cucumber deformity and increase yield and economic value. Cucumber wants to achieve high yield, with the development of agricultural technology, spray potassium dihydrogen phosphate foliar fertilizer every 7 days in the early stage of flowering and fruiting, and spray a total of 2-3 times will have a good effect.

The above is my personal opinion, I hope it can help you.

This is because cucumbers that look like this look particularly ugly, and others think that the taste is problematic, so it will affect sales.

Because it's not pretty. People will also look at the appearance when they buy things, and the deformed cucumber will not look good, so people don't buy it.

The production of cucumber deformed melons is often due to insufficient nutrition, the influence of environmental conditions (such as low temperature in the early stage and high temperature in the later stage), rapid changes in soil moisture, or due to poor fertilization and uneven seed development. The main way to prevent deformed melons: strengthen field management, ensure that the nutrients can be sufficient, the needs of cucumber growth, and ensure that the water is sufficient and uniform during the fruiting period.

Mainly because the deformed melons grow too ugly, people don't like deformed cucumbers very much.

When the temperature difference between day and night is less than 2, or even the night temperature is higher than the daytime temperature, it is easy to appear thin waist melon. On the contrary, if the temperature in the greenhouse reaches 30 for a long time during the day on a sunny day, and then it is lower than 16 in the first half of the night, the excessive temperature difference between day and night will make the plant develop in the direction of reproductive growth, producing a large number of cucumbers, and the vegetative growth ability of the plant itself will slowly weaken, resulting in a large number of deformed melons. After May every year, the outside temperature rises, when the temperature in the greenhouse is higher than 30 for a long time, the quality of cucumbers will be seriously reduced, and deformed melons such as sharp mouths, big bellies, and curved melons will also be produced in large quantities.

Because these deformed cucumbers are particularly poor in appearance and look particularly ugly, people will not buy this kind of cucumber.

Because the misshapen cucumber is very ugly, it makes people feel that such cucumbers have germs, so they are generally not purchased.

Because consumers don't like it, consumers feel that such melons are not delicious and not good-looking.

Cucumber is the handle in our vegetable garden, the number of planting has always been in the first place, which is also due to the easy management of cucumbers, more fruits, long cycles and many other advantages, cucumbers as water vegetable planting, as long as there is water under the premise, cucumbers can grow very quickly, flowering, fruiting, but will also encounter cucumbers seem to grow very vigorously, lush branches and leaves seem to be dense one, but flowering and fruiting is not very much, resulting in cucumbers too prosperous situation or a lot of hair, what are the reasons?

In fact, everything has a degree, whether it is fertilizer or watering, for any plant, if you do it, it will be counterproductive, and all plants are like this.

Fertilizer and water are too sufficient: one of the main reasons for the occurrence of cucumber over-prosperity is that the combination of fertilizer and water is not reasonably applied, such as during flowering and fruit setting, the use of nitrogen fertilizer is too much, it is easy to cause cucumber leaves to be fat, branches are long, flowering, fruit setting will become less, the main nutrients are supplied to the branches and leaves, this situation is easy to appear vigorous, to supplement the use of other fertilizers, phosphorus and potassium fertilizer, boron fertilizer should be added reasonably, reduce the use of nitrogen fertilizer during flowering and fruit setting, so as to control water, Water control for a few days allows the cucumber to be curbed, and the dosage of fertilizer is adjusted to reduce the growth.

Take manual pinching: cucumber growth, mainly the branches are nutritious, the nutrients absorbed by the roots should be volatilized, and the production of vigorous growth is also a lot of hair phenomenon, you can use your fingers, gently pinch the root of the cucumber below, feel the creaking sound, the cucumber root main vine pinching flattened, can also block the delivery of nutrients very well, play a role in slowing down the growth of cucumber, pinch the main vine of cucumber, should not be too hard, to avoid pinching off the branches, causing plant death.

Topping pinching head: take the way of topping, but also a measure to slow down the growth of cucumbers, remove the top tips of vigorous cucumbers, let it germinate more side branches, so as to blossom and bear fruit on the side branches, topping should also be based on the planting time of cucumbers and the variety of cucumbers, not all cucumber varieties are suitable for topping, some cucumber varieties are only on the main vine to bear fruit, it is not possible to carry out topping measures.

Spraying drugs: cucumber branches are too long, the leaves are thick, and the phenomenon of long growth is obvious, then it is necessary to spray drugs, use biological regulators, and improve the growth of cucumbers, which is also the most common measure for planting cucumbers in a large area.

Cucumbers planted in spring, which will be during the fruitful period, hot summer, cucumbers as an indispensable fruit on the table of our daily life, the contribution is very large, delicious cucumbers, do you like to eat? Everyone is welcome to add comments and leave a message, thank you.

In fact, this situation is considered overnutrition. Generally, due to excessive fertilization and watering, the temperature difference between day and night is large, the temperature is high during the day, and the temperature does not drop at night, but the temperature is very low in the morning, so that the cucumber vine grows rapidly due to excess nutrients, and will continue to germinate and branch.

It may be caused by overnutrition, too much fertilization and watering cause the cucumber vine to grow rapidly, continue to germinate and branch, should have less flowering, hanging fruit, but also because of too much nutrition, resulting in the fruit is very small and yellow, falling.

It may be that the fertilizer is not used reasonably enough, resulting in excess nutrients and steep growth of the plant, or it may be that the watering time is not grasped properly.

Hello, dear is happy to answer for you. Cucumber is more nitrogen fertilizer and grows vigorously, which will affect the fruit setting rate. In cucumber planting management, vegetative growth and reproductive growth are inseparable.

When too much nitrogen fertilizer is used, vegetative growth is more vigorous, which will inhibit reproductive growth, which will lead to the phenomenon of more flowering and less fruit set. The temperature was high during the flowering process, which affected the fruit setting rate. In the case of high temperature, the pollen will be inactive, which will directly cause the phenomenon of inpollination, and then affect the fruit setting rate.

Cucumbers have more male flowers and fewer female flowers. The reason for this is that during the differentiation period of cucumber flower buds, many environmental factors are affected, such as light, temperature, water and fertilizer, medication, variety, etc., and a variety of reasons lead to fewer female flowers in cucumbers. The planting density is relatively large, and the ventilation is poor.

Cucumbers are cross-pollinated, mostly pollinated by wind and bees. If the planting is dense, it will affect pollination and fruit set. There is a lot of nitrogen fertilizer, and the phosphorus and potassium fertilizer boron is insufficient, and it grows vigorously.

"Cucumbers bloom more and bear less fruit may be caused by several reasons. First, improper fertilization, too much compound is applied, resulting in poor root absorption capacity, which affects growth. The second is that the pesticide is overdosed, and the concentration exceeds the standard to bring pesticide damage, and the growth point cannot grow normally, which affects the results.

The third is improper watering, the humidity is too high, the roots are soaked, the growth is inhibited, and it is difficult to bear fruit. Fourth, it rains during flowering, which affects pollination. It shows that there is too much nitrogen fertilizer, and more phosphorus and potassium fertilizers should be applied.
