What causes a large number of curved melons when growing cucumbers? What to do?

The soil is poor and permeable, which leads to poor development of cucumber roots, premature leaf senescence, leading to malnutrition and melon bending. In case of bad weather, insufficient light, weakened photosynthesis, and less nutrients are produced, which cannot meet the needs of rapid growth of cucumbers. The elongation speed of the melon strips slows down, and the melon is easy to bend.

The early stage of the plant bears too much fruit, and the later stage of fertilizer removal is prone to bent melon. When using seedling cultivation management, too early leaf picking destroys nutrients**, resulting in nutrient deficiency and melon bending. Cucumber flowers are of poor quality and the ovary is small.

Even if it can be pollinated by flowering, the nutrients obtained in the later stage are relatively small, and it is easy to appear crooked melon. It takes a certain amount of time for melon strips to expand, improper planting management, and temperature, humidity, and light are not up to standard, which will cause cucumbers to bend.

High temperature causes plants to grow wildly, and potassium and boron deficiency may also occur sharp melons and curved melons. Excessive application of nitrogen fertilizer or high nitrogen content of chicken manure, duck manure, pig manure and cow manure, etc. , resulting in insufficient potassium and phosphorus fertilizers, and is also prone to cucumber bending or other deformities.

Melon strips are harmed by mouthpart pests, such as thrips, and biting can easily cause melon bends. The physical collision between the melon strips and the stems and leaves can easily cause melon bends. The solution to the curvy of cucumbers.

Cucumber bending should be precautioned, reasonable and scientific watering and fertilization, temperature and light should be controlled during the growth period, cucumber bending should be minimized, and root melons should be removed in time. When the cucumber appears to be bent, remedial measures should be taken. If it is a young melon with a light curvature, it can be straightened with a bottom pendant; It can also be done by applying growth regulators**.

Apply gibberellin to the inner surface of the curvy gourd, and the curly melon will straighten after a few days. Preventive measures can also be taken in the early stage, such as appropriately increasing the planting density, reducing the yield per plant, timely thinning flowers and fruits, leaf senescence, and reducing melon bends; Boron and potassium dihydrogen phosphate solutions can also be sprayed regularly to prevent the melon body from bending or deforming.

The above are the reasons for cucumber bending and the solutions. In the process of planting, it is necessary to strengthen water and fertilizer management, reasonable fertilization, scientific watering, and control the temperature and light of the growth environment. When erecting vines, it is necessary to pay attention to leaving space for the growth of cucumbers, thinning flowers and fruits in time, and spraying some drugs appropriately for prevention.

It is possible that the roots of the plants are decaying because the plants have dried up, too much fertilizer, too little watering, lack of nutrient solutions. When we encounter this situation, we can solve this problem by watering, spraying insecticides, spraying nutrient solutions, spraying pesticides and fertilizing.

It may be that the temperature is relatively high, it may be affected by the environment, for example, continuous rainy days may be the cause of the variety, or it may be a breeding of pests and diseases, or the temperature of the flower buds in the process of differentiation is relatively low, we must analyze the specific problems, do not be too dense in the planting process, water and fertilize in time, and supplement fertilizer in time.

It may be that you did not water in time, at this time you try to water as much as possible to ensure the moisture of the soil, but also pay attention to field management, you can increase organic fertilizer appropriately.

It may be a phenomenon that the cucumber in the young fruit stage stops growing and developing due to insufficient nutrients or untimely topdressing.

So, when cucumber is planted, how can farmers fertilize to avoid the occurrence of the above-mentioned physiological diseases?

Fertilizer characteristics of cucumbers.

Although cucumbers like fertilizer, they are not tolerant of fertilizer. Therefore, only when farmers have mastered the fertilizer needs characteristics of cucumbers, can they apply fertilizer well, apply fertilizer to the right fertilizer, and maximize the fertilizer effect.

1. Nitrogen. Cucumber is sensitive to nitrogen, and if the soil lacks nitrogen, it will not only lead to slow growth of seedlings, but also affect the absorption of calcium and magnesium, thereby reducing the yield of cucumber.

2. Phosphorus. The phosphorus requirement of cucumber is lower in the early stage of growth, but the demand will increase during fruit expansion and harvest to promote fruit development.

3. Potassium. Cucumber has the largest absorption of potassium, and potassium is very important for the whole process of cucumber growth.

Cucumber fertilization points.

1. Apply plantar fertilizer. The basal fertilizer of cucumber planting needs to be reapplied to decompose organic fertilizer to enhance soil fertility, which is conducive to the growth and development of cucumber seedlings. Generally, 4-6 tons of decomposed farmhouse fertilizer or 400-600 kg of commercial organic fertilizer, 18-36 kg of phosphorus nitrate fertilizer, and 3-6 kg of potassium sulfate are applied per mu to promote the accelerated development of seed roots, increase the length and depth of roots, and the rapid growth of seedlings.

2. Timely top dressing. In the whole growth stage of cucumber, timely topdressing is important for strengthening seedlings, promoting flowering, and fruiting. Generally, it is necessary to top dressing 3-4 times, such as topdressing to promote seedling fertilizer, melon fertilizer, melon fertilizer, etc.

The amount of top dressing should not be too much each time, and 8-12 kg of urea and 5-10 kg of potassium sulfate can be applied.

3. Skillful application of foliar fertilizer. In the fruiting period of cucumbers, it is necessary to apply fruit fertilizer in a timely manner. Generally, foliar spraying once every 8-12 days 1% urea solution + 4% Bika potassium dihydrogen phosphate + chelated boron solution, or amino acid chelated calcium, magnesium, boron, copper water-soluble fertilizer + urea solution + potassium dihydrogen phosphate solution can play a role in promoting melon and seedling, prolonging the harvest period of melon and fruit, and preventing premature aging.

In this case, it fully illustrates that a kind of cucumber may have too much fertilizer and hurt the roots and seedlings of the cucumber.

The reasons why cucumbers are bent are both physiological and physical. Physiological reasons are mostly caused by the weakness of the main stem, lack of nutrients, the production of assimilated substances in the leaves or the inability of the assimilated substances in the leaves to be smoothly transported to the melon.

The primary factors are as followsFirst, the fertilization is not complete, only one side is fertilized, resulting in the growth and development of one side of the melon, and the other side is not very good, and the result is crooked;

Second, the temperature of the flowering promotion period is too low, and the delay time of ultra-low temperature below 10 is too long;

3. The standards of temperature, light, and moisture are unreasonable, such as insufficient light, insufficient fertilizer and water, or uneven supply of fertilizer and water;

Fourth, the number of transplanted plants is too large and too dense to endanger natural ventilation and light transmittance;

Fifth, it is to pick too many leaves, or to bear too many fruits, to compete with each other for nutrients, or to hurt the roots;

Sixth, it is low potassium and boron deficiency;

7. It is harmed by pests, such as melon strips contaminated with scab disease will bend from the lesions;

8. It is the efficacy of mechanical equipment, such as tying knots, ropes, tendrils, etc.

Plenty of light

When planting in greenhouses, due to the light standard deviation, there should be sufficient plant spacing when planting to ensure sufficient light. However, it is important not to pick too many leaves to ensure that sufficient photosynthetic products are produced.

Effective liquid fertilizer

Cucumbers enter the early flowering period, and small melons begin to grow, so they can not be watered at this time, at least not a lot of watering, and not more fertilizer; The cutter head is solved. Once the curved melon is produced, before and after the young flowers open to the outside world, use a spatula to draw 1 shallow mark vertically on the back of the curved melon, and then 1 3 shallow marks on the cross-section, deep but centimeters, 2 5 cm long. In this way, the melon can be straightened, and the window is basically invisible when it is sold in the market.

The leash is straight

Take small tiles, small bricks or small stones within 4 cm long and 2 cm wide, and tie them with thin rope or thin plastic rope. When the cucumber grows to 10 cm long, if you find the curvy gourd, you can hang a small tile or a small brick on the cucumber flower handle, so that with the growth of the cucumber, the small brick can straighten the curvy gourd.

Pick tendrils and remove curly melons

Cutting off the tendrils can avoid the condition of bent melons caused by physical obstacles such as tendrils.

Yield control

Improve cultivation techniques.

Speaking of cucumbers, everyone should be familiar with them, not only fried and eaten, but also eaten raw, cucumbers have a refreshing taste and are favored by many people. When we pick cucumbers, we also like to buy some cucumbers that look straight and are also very fresh. In rural areas, there are also many people who like to plant some cucumbers in their yards, but in the process of planting, sometimes they will find that cucumbers become bent when they are planted, so we must first find out what causes cucumber bending, so as to better improve it.

There are many reasons for the curvature of cucumbers, if the cucumber is not evenly fertilized in the process of fertilization, that is, only one side of the egg cell is fertilized, in this case, the cucumber is unable to really complete the fertilization process, so it will also lead to the curvature of the cucumber. In addition, if the cucumber is very short of fertilizer during the growth process, and the soil is relatively dry, it will also cause the cucumber to bend.

In the process of growing cucumbers, if we use too much nitrogen fertilizer, or some inferior fertilizers and some hormone fertilizers, it will also have some impact on the soil for a long time, making the soil acidic, salinized, etc., in the growth process of cucumbers, the soil does not provide sufficient nutrients to cucumbers in time, which will also lead to the bending of cucumbers. In addition, it may also be that some pests and diseases cause cucumbers to bend, such as some powdery mildew and downy mildew and other pests and diseases, which will also have a certain impact on the growth process of cucumbers, so that cucumbers do not have sufficient nutrients, so the cucumbers that grow out of the collapse will become curved melons.

For this situation, we can also take corresponding measures to improve, and it is very necessary to pick the leaves reasonably during the growth process of cucumbers. Reasonable removal of some excess yellow leaves, diseased leaves, etc., can effectively avoid the waste of excess nutrients in the growth process of cucumbers. In addition, we should also carry out balanced fertilization, reasonable watering, in the growth process of cucumbers, do not water too much at one time, watering should be more diligent, the amount should be less.

Cucumbers are always bent when they grow, and the thick clumps may be caused by lack of nutrition, or there are diseases and insects on the cucumbers, which will lead to the bending of the oranges; It is necessary to pay more attention to the growth of cucumbers, and to let cucumbers shine more in the sun, to keep ventilation, and to remove insects regularly, so that cucumbers can grow better.

It is very likely that the cucumber that is growing early has encountered some hanging wires, and the temperature is too high when flowering, so it will bend, so you must pay attention to this, and then be sure to remove some excess hanging wires, and pay attention to cleaning up stagnant water.

It may be that the temperature outside is too high, it may be a lack of organic fertilizer, or it may be that the flower buds are malnourished when the hungry grandchildren are differentiated. Be sure to use hormone fertilizers in a timely manner, and also use some organic fertilizers in the rotten chain, and do not use inferior fertilizers in closed types.

Cucumber is a very common fruit and vegetable in people's lives, which can be eaten raw and stir-fried, and is deeply loved by people. But in the process of planting cucumbers, in addition to the possibility of some pests and diseases, there will also be some physiological diseases, in the process of planting cucumbers, cucumber bending and large-headed melons are often encountered by our growers. This kind of deformed cucumber not only has poor color and no nutrition, but also has no commercial value, which greatly reduces the planting efficiency of our farmers.

In the process of cucumber planting, the phenomenon of curved melon and big-headed melon often occurs, which are all deformed melons. To prevent the occurrence of cucumbers, crooked melons, and big-headed melons, we must first understand the causes of their occurrence. There are both physiological and physical reasons for the production of cucumber curved melon.

Physiological causes are mostly caused by emaciation, malnutrition, and the lack of assimilates manufactured in the leaves or the inability of the assimilates in the leaves to be transported smoothly into the fruits.

Spraying 200 grams of 30% ethephon with 400 kg of water at the seedling stage, or spraying wine with sodium naphthalene acetate brine solution at the stage of 2-3 true leaves of cucumber can increase the number of female flowers. Water management is not in place, such as dry and wet, especially in the peak period of melon, it is necessary to ensure water **, otherwise it is easy to cause poor root growth, melon and deformed melon chopping, seriously affecting the yield and quality. Usually cucumber has the above symptoms, we generally call it deformed fruit, which is a physiological problem, is a manifestation of unbalanced growth of cucumber, and the normal growth of cucumber is a melon strip with uniform thickness.

There are many kinds of deformities with large and small heads, curved, and the sharp-billed melon is mainly in the flowering period of cucumbers, and the female flowers are not pollinated, resulting in malnutrition at the tip, and they will grow into sharp-mouthed melons. There is also a sharp mouth melon waist and a thin mouth when the nutrition cannot keep up, so we must do some first aid measures in time, so let's talk about this problem from two aspects. Cucumber is one of our common vegetables, whether it is growers or consumers like which kind of well-proportioned and straight and long, if you choose cucumber bending phenomenon when planting, it will affect the value of the commodity, resulting in a decline in income, which is a headache.

The appearance of cucumber curls is caused by insufficient light, low temperature and malnutrition. In addition to improving the cultivation conditions, the solution can also use the technology of straight fall of the curved melon, the effect is very obvious, and there is no pollution, and there is a high promotion value.

It should be watered frequently, and pests and diseases should also be noted, and weeds should also be removed frequently, with some good fertilizers, so that the bending of cucumbers can be prevented.

You can spray pesticides in advance for prevention, and in the early stage, you must choose the right seeds, and you must put the cucumber shelf well, otherwise these problems are easy to occur, and you must eat enough fertilizer to ensure nutrition.
