What are the causes of cucumber curtains? What do you do to prevent it?

It may be caused by uneven pollination or incomplete fertilization of cucumbers in the process of pollination and fertilization. Like this year's Dragon Boat Festival is a little too much water, floods have occurred in many places, rainy weather for many days, cucumbers absorb more water, evaporation is small, but after the rain is too clear, in the conditions of high temperature and strong light caused by a sudden increase in moisture, and the root system due to the large soil moisture content to prevent cucumbers from appearing curved melon, to ensure sufficient light. Appropriate plant spacing, but be careful not to pick too many leaves to ensure enough leaves to produce nutrients.

Environmental impact: Weather reasons will also cause the appearance of curved melons, such as cloudy days for a few days and then suddenly sunny, then in the case of high temperatures, the whole melon strips will be balanced, resulting in curved melons. The cucumber pollination process is incomplete, or the process is completed, but the fertilization process is incomplete, and it may be because the dry matter synthesis of the cucumber after fertilization is reduced, and the nutrient distribution is uneven, resulting in "bending" melon.

Insufficient fertility, insufficient or unreasonable nutrient supply is one of the important reasons for the appearance of crooked or deformed melons, cucumbers produce more melons, require a large amount of fertilizer, and the shortage of a large number of elements and medium and micro elements will cause poor growth, which directly affects the yield not to mention the quality of melons. If you want to plant a second crop of cucumbers, the yield is often low, and the cucumbers are more curved. We know that the growth of vegetables is generally carried out at night, and the temperature at night is too high, which will affect the growth of vegetables.

Ventilation and increased application of foliar fertilizer, cucumber bending should be improved.

<> the external environmental conditions are uncomfortable, if it suddenly clears on a cloudy day, the high temperature and strong light cause the lack of moisture and nutrients. Pest and disease damage, such as melon strips infected with scab, will bend from the lesion. If one or more of these elements are missing or the supply is unbalanced, the growth of cucumbers will be affected.

Especially during the cucumber setting period, the specific manifestation of nutrient deficiency or element imbalance is the appearance of "bent" cucumbers.

The reason for cucumber and crooked gourd, the temperature of cucumber flowering is too high or boron deficiency, resulting in unbalanced development of melon strips, when the cucumber is drought, the amount of watering is too large or the watering is not timely, it is easy to cause curved gourd and melon; The prevention and control methods include strengthening greenhouse temperature management, balanced fertilization, and reasonable watering.

Environmental factors, bad weather, rainy and rainy caused by insufficient light, easy to cause curlough, too high temperature, easy to cause curlough soil factors, poor soil, poor permeability leads to poor root development, premature leaf aging, easy to cause curlough management factors, nutrients are insufficient, resulting in fertilizer deficiency during the fertilizer period, especially potassium, boron, phosphorus, or partial nitrogen fertilizer, over-application of chicken, pig, cow manure, are easy to cause curlough, too much leaf picking will also damage nutrients, causing curlough.

There are several reasons for cucumber curcumber: Excessive and premature leaf picking. Too much fruit per plant in the early stage.

The ovary is too small at the time of flowering, resulting in insufficient nutrients later on. Long-fruited cucumber should not be used properly in the fruit expansion period. The results were normal at first, but later the nutrients could not be supplied in time.

Long-fruited cucumbers encounter leaf obstruction during the expansion stage. High temperatures cause potassium and boron deficiencies. Excessive or single use of nitrogen fertilizer or chicken manure, pig and cow manure, insufficient potassium fertilizer and phosphorus fertilizer, etc.

Prevention and control methods of cucumber and curcumber: 1. It is to water frequently, but the amount of watering should be less each time, and the watering interval should not be too long during the high temperature period. 2. The yield of a single plant can not be too high, too high a single plant yield will increase the burden of the plant, too many melons in the early stage or not picking melons in time, the leaves will age quickly, which will easily lead to cucumber bending.

3. Don't remove the bottom leaves too early and too much. The yield of cucumbers mainly depends on the photosynthesis of the leaves, as long as the bottom leaves do not turn yellow, generally do not remove them too early. 4. Remove the curved gourd that has occurred in time, or use small stones or small bricks to fall to the bottom to make it straight.

In addition, foliar spraying of compound microbial fertilizer 200 times, spraying once every 7 days, spraying 2 3 times, has a good control effect on the production of curved melon, sharp melon, and potbelly melon.

Physiological curvy gourd: such as lack of fertilizer (potassium, boron, etc.), drought, low temperature (the temperature of the flower bud differentiation stage is too low, and the low temperature below 10 lasts for a long time) is easy to form curved gourd.

Pest and disease hazards: cucumber powdery mildew, downy mildew, horn spot, wilt and other infectious diseases, shed whiteflies and other insect pests, will make a large increase in curved melon.

Strengthen fertilizer and water management: the base fertilizer is mainly organic fertilizer, and appropriate fertilizer should be used according to the characteristics of cucumber in the later stage, avoiding partial application of nitrogen fertilizer, and paying attention to the supplement of medium and micro nutrients.

Plant management: prevent bent melon caused by mechanical reasons such as tendrils, frame materials, stems and leaves.

If you want to control cucumbers, you need to make the cucumber rattan pen posture too straight. In the early stage, don't let the cucumber pick up too many sources. In addition, it is necessary to breed excellent varieties and fertilize cucumbers to make the plants nutritious.

On a sunny day, you can use some adjustment agent to slowly apply it to the surface of the curved cucumber, so that after a few days, you can grow straight, this method is also very simple and effective.

First, do not remove the bottom leaves too early and too much, the yield of cucumbers mainly depends on the photosynthesis of the leaves to improve the yield. As long as the bottom leaf is not yellow, it should not be removed too early, unless the bottom leaf is functionally prematurely senescent. In order to prevent and control the premature leaf senescence of cucumbers, nitrogen, phosphorus, potassium fertilizer, microbial fertilizer, multi-element mineral fertilizer and organic fertilizer should be reasonably used in fertilization. In the early stage, organic fertilizer and nitrogen, phosphorus and potassium fertilizer have been used, and now 20 kg of microbial agent and 20 30 kg of multi-element mineral fertilizer can be applied per mu to promote the growth of cucumber roots, supplement nutrients, and prevent and control premature aging of cucumber roots and leaves.

The second is to search for this slag to water frequently, but the amount of watering should be less each time. The third is that the yield of a single plant can not be too high, too high a single plant yield will increase the burden of the plant, too many melons in the early stage or not picking melons in time, the leaves will age quickly, and it is easy to form curved melons.

If you want to control cucumber curvy, you can put a straight plastic bucket on the outside of the cucumber to guide the growth of cucumber.

Cucumbers are one of the most common vegetables that farmers often grow. When growing cucumbers, in addition to common pests and diseases, the biggest headache for farmers is probably the problem of deformity and bending of cucumbers.

1.It may be caused by uneven pollination or incomplete fertilization of cucumbers during pollination and fertilization. Those who pollinate more will grow faster, and those who pollinate less will grow more slowly, causing bending.

May be curved due to developmental delay. In the process of planting, the planting density of cucumbers is too large, and when cucumbers grow, they are hindered by external branches, leaves, stems, etc., resulting in the inability to droop and grow normally, resulting in bending

2.Curves caused by external climatic factors! If cucumbers encounter drought or low temperature days during the growing season, the growing point will be significantly inhibited, resulting in bending!

Warping caused by nutrient deficiency will cause deformities such as bending if the nutrients are insufficient to meet the growth needs of cucumber fruits during the rapid growth period. Bending caused by pests and diseases. During the growing season of cucumbers, if thrips suck the juice from the fruit, they will bend in the severely damaged area; Or if it is scabbed, the melon strips will bend from the lesion!

3.To prevent cucumber bending, the most basic thing is to do a good job in the prevention and control of cucumber diseases and insect pests and nutritional supplements, and to do a good job in the prevention and control of cucumber diseases and pests. The most serious pest of cucumbers is thrips.

Farmers are advised to use acetamiprid and thiamethoxam. prevention and control of spinosadin; For diseases, it is necessary to do a good job of prevention in advance, and spray zinc, methyl tobuzin, azole amate, etc. every 10 to 15 days to avoid the occurrence of diseases as much as possible. Do a good job of nutritional supplementation of cucumbers.

In the early stage, it is recommended to use 40-50 kg of balanced compound fertilizer per mu, with organic fertilizer as the base fertilizer! After the cucumber has flowered and fruited, it is recommended to carry out top dressing to meet the needs of its flower bud differentiation. Do a good job in the supplement of medium and trace elements, and spray boron fertilizer 2 3 times on leaves at the bud stage, flowering stage and early melon stage, which is conducive to promoting pollination and fertilization; spray calcium fertilizer 3 3 4 times to improve the stress resistance of fruits; From the flowering stage to the whole melon stage, the foliar magnesium fertilizer was sprayed 2 3 times; Of course, potassium dihydrogen phosphate is also a good choice.

Cucumber malformed melon is caused due to poor management. The number of deformed melons can measure the level of field management, and it is also an indicator of the yield and quality of cucumbers, which determines the level of income. At the beginning of the period, pay attention to the careful management of each growth stage.

to reduce the occurrence of deformed melons.

Mainly because the soil is poor, coupled with the lack of water and fertilizer, it is easy to bend; The soil should be kept fertile, watered more, kept in plenty of light, and kept at a suitable temperature.

On the one hand, it is due to incomplete fertilization, and on the other hand, it is also due to insufficient light; We should choose some varieties with strong disease resistance, do a good job in proper water and fertilizer management, and build a frame for them in time to ensure that they can get sufficient sunlight.

Sometimes it is because of uneven pollination, poor root development, poor soil, and lack of fertilizer; The soil should be kept fertile, watered and fertilized in a timely and scientific manner, and moderate light should be maintained.

It may be caused by uneven pollination or incomplete insemination of cucumbers in the combination of pollinated sperm eggs. Bending caused by stunted growth. The relative density of cucumber planting is too large, and when the cucumber grows, it is blocked by external branches and stems, resulting in the inability to grow normally, resulting in the phenomenon of bending.

Bending caused by external climatic factors! If the cucumber grows in the growing season, suffers from drought or ultra-low temperature, the growth is significantly inhibited, resulting in bending!

After transplanting cucumbers, at the beginning of flowering, the flowers gradually grow, at this time, you can not water floods, you can use small water. When the melon grows to about 10 cm, the cucumber will grow rapidly, and there is an urgent shortage of water and nutrients at the moment. The lack of fertilizer and water at the moment will cause crooked melons.

In the growth of cucumbers, it is best to spray potassium dihydrogen phosphate and boron fertilizer before flowering. Promote pollination to avoid deformed fruits. Cucumbers are subjected to high temperature and humidity during the growth process, and the adverse climate influence will also produce curved melons.

Do not prematurely remove the leaves at the bottom of the cucumber plant: the key to the yield of cucumber is to rely on the leaves to cause plant photosynthesis, so as long as the leaves at the bottom of the cucumber do not turn yellow, it can not be cut prematurely, because the mature leaves it photosynthesis efficiency is very high, but also to increase the production of cucumbers. Planting cucumbers can not be separated from fertilizer, not only to apply enough rotting organic fertilizer, but also should be matched with nitrogen, potassium and other fertilizers, followed by in the middle and late stages of cucumber growth, 1 mu can be applied microbial fertilizer 20kg and its diversified mineral fertilizer 25 to 30kg, which can promote the development of cucumber rhizomes and prevent the emergence of "curved melon".

Poor sunlight exposure, planting density has a great impact on cucumber bending, outdoor and greenhouse planting is mostly related to relative density, such as greenhouse cucumber is usually 3000 4000 acres, outdoor 4000-4500 acres. Temperatures above this relative density tend to reduce the duration and total area of plant voids. If photosynthesis is affected, it will inevitably cause problems at all stages of growth such as plants and cucumbers.

When in full bloom, spraying polynuclear composition can be excellent pollination without dipping growth hormone into flowers, and it is not easy to pollinate poorly.

It may be that there is a shortage of water, or it may be that water and fertilizer management is not in place. It is best to choose well-rotted organic fertilizer, and also water frequently to ensure the moisture of the soil.

What are the reasons for cucumber "bending"? Uneven pollination: First of all, it may be caused by uneven pollination or incomplete fertilization of cucumbers in the process of pollination and fertilization.

How do you avoid cucumber bending? Do a good job in the prevention of cucumber diseases and insect pests: the serious insect pest of cucumber is thrips, and it is recommended that farmers use acetamiprid, thiamethoxam, ethyl spinosam, etc. for control; For diseases, it is necessary to do a good job of prevention in advance, with an interval of 10 to 15 days, spraying zebze, thiophanate-methyl, pyraclostrobin, etc., to avoid the occurrence of diseases as much as possible.

It may be a lack of organic fertilizer, or it may not be a good vine introduction, you can properly thin flowers and fruits, and use chemical solutions reasonably, and water properly.

The main reason for the curvature of cucumbers is the lack of nutrients necessary for growth. Careful cultivation and the provision of nutrients to cucumbers can prevent the symptoms of cucumber bending. Although there are many varieties of cucumbers, they are one of the favorite vegetables of people.

One of our common ones is more straight and green, and occasionally we will see some strange cucumbers appear. This type of cucumber is usually curved and does not taste very good. Normal cucumber has the characteristics of fresh taste, large moisture, and very thirst-quenching, which is the easiest and cheapest choice to quench the heat in summer.

However, this curved cucumber has a slightly bitter taste and is not very popular with the public. In order to improve this appearance and sales, the following will introduce several prevention and control methods.

Cucumbers are mainly grown and harvested during the summer months. Because the sun is relatively large in summer, the sunlight is too long, and the moisture is reduced. At this time, it is necessary to give the cucumber enough water and replenish nutrients in time.

This method ensures that cucumber roots and seedlings absorb nutrients quickly. In the summer, there is also a lot of rain. At this time, the moisture in the soil increases rapidly, which has a great impact on the absorption capacity of cucumber roots and seedlings.

A large amount of rain can easily cause cucumbers to bend, so you must pay attention to rain protection at this time. Too little or too much water can cause cucumbers to become bent.

Any plant can be affected by pests during its growth. Similarly, cucumbers cannot grow properly if they are infected with pests. Generally, the infected part of the cucumber cannot grow, but the other part will continue to grow in the same way without being harmed.

This will cause the cucumber to become bent. At this time, melon farmers must check regularly. Spray the cucumber leaves with the appropriate medicine to ward off this damage so that the cucumber can grow straight.

Cucumbers that have become bent can be manually intervened to re-straighten. The method is also very simple, you only need to lift the curved part with a heavy object. In fact, many cucumbers become bent because they are not managed in time.

Strong seedlings can be selected at the early stage of planting and carefully cared for at all stages, so as to reduce the occurrence of cucumber bending.
