Cucumbers wilt when they don t grow big, what are the reasons for this?

Cucumbers shrink when they don't grow big, and there are several reasons for this.

1. The temperature is too low: cucumbers themselves are crops that like warm environments, and their cold tolerance is relatively poor. If there is continuous low temperature and rainy weather after fruiting, and the temperature cannot be controlled in time, there will be small leaves, poor growth, and even cucumber shrinking and falling.

Be sure to pay attention to changes in temperature during its growth. In spring, avoid the cold spring, increase the temperature in time, and spray potassium dihydrogen phosphate in time.

Brassin and other prevention of low temperature environment.

2. Insufficient water: the growth of cucumbers needs sufficient water, if the weather is dry for a long time, then the cucumbers will shrink because of the lack of water, at this time, it is necessary to replenish water to the cucumbers and keep the soil slightly moist, so that the cucumbers can grow healthily and vigorously.

3. Improper pruning: During the growth period of cucumbers, we should not only pay attention to the external environment, fertilizer and water management, but also pay attention to timely pruning. If there are too many deformed melons on the plant and a lot of nutrients are consumed, it will affect the normal growth of melons and is prone to shrinkage.

It is necessary to prune and deal with it in time, remove the deformed melon, reduce nutrient consumption, promote more concentrated nutrients, promote the better growth of healthy melons, and avoid shrinking and falling melons.

4. High temperature weather.

Cucumber likes warmth, it is not resistant to high temperatures, if the temperature is higher than 35, cucumber can not carry out good photosynthesis.

If the temperature is higher than 45, there will be a high temperature obstacle for cucumbers, so that cucumbers will not grow large and shrink, so take cooling and ventilation measures for cucumbers in time in hot weather.

5. Insufficient nutrients: In the process of cucumber growth, if the nutrients are insufficient, then it will not grow up and shrink, so when the cucumber fruit grows, it is best to apply thin fertilizer to the cucumber every 7-10 days, and at the same time you can also spray some foliar fertilizer for it, which can promote the growth and maturity of the cucumber fruit. Cucumber in the growth period of the demand for fertilizer and water is relatively large, if the fertilizer water is not high, the plant growth is thin, it will reduce the normal fruiting ability, easy to shrink.

Pay attention to the nitrogen fertilizer after the fruit.

The dosage of potassium fertilizer should be applied more to avoid the growth of plants, which can also ensure sufficient nutrition and avoid cucumber shrinkage.

6. Cause of disease: cucumber grows not big and shrinks, and it may be caused by disease, in this case, it is best to pull out the seriously damaged cucumber plant to avoid the spread of germs, and then spray the cucumber with the corresponding sterilization agent to completely eliminate the germs, so that the cucumber can bear normal results.

cucumber planting process, if the management method.

If it is not appropriate, the plant will grow, and the nutrients absorbed by the roots will not reach the melon strips, and all will be absorbed by the melon vines.

Melons appear. To plant cucumbers, apply foot fertilizer, 5-10 square meters of rotted cow manure and chicken manure per mu, compound fertilizer.

50 kg, apply more organic fertilizer, improve soil conditions, and cultivate strong roots. It is also important to dress properly and reasonably.

<> watering of cucumbers requires water-saving measures. Planting cucumbers, using plastic film covering, drip irrigation method under the plastic film, can prevent the traditional use of large water flood irrigation caused by root damage, can also reduce the evaporation of soil moisture, reduce the humidity of the air, cucumber fruiting ability is very strong, basically every node can produce melons, if the nutrients are sufficient, melon strips can not be thinned, but if there is a curved melon, melon and other phenomena, it is necessary to carry out part of the thinning of melons and flowers, you can go to one after two.

The open-air cucumber excludes various diseases, the cause of lack of water, as long as there is a single plant out of the sun wilting phenomenon, it must be the underground pest to bite the root of the cucumber, so it is necessary to use medicine to do root irrigation. Soil treatment with 98% cotton long microgranule 20 kg per mu can kill most of the germs in the soil; Finally, targeted medication should be used, and 70% Tobuzin wettable powder should be used to make a paste and apply it to the diseased area to prevent and treat Verticillium wilt.

The concentration of fertilization should not be too large, especially near the part of cucumber rhizomes, the concentration of fertilization in this part should be as low as possible, the prevention and control of too high concentration of fertilizer will burn the cucumber, and the fertilizer with high nitrogen content should also be used cautiously, in the high temperature environment will lead to the poor development of yellow light roots, the best growth temperature of cucumber roots is 20 to 25 degrees, but in summer, the temperature will reach 30 degrees many times, such an environment is not conducive to the growth of cucumber roots. Individual plants wilt; The growth of wilted plants can be promoted by temporarily not topdressing, hydration, and plucking of female flowers.

In daily life, you know that cucumbers wilt when they don't grow big, what are the reasons for this? Cucumber is a kind of thermophilic crop, continuous low temperature rainy days, if no measures are taken, can not reach the temperature of cucumber growth, small leaves, poor growth, less photosynthetic substances, can not meet the nutrients required for cucumber growth, will cause melon. In addition to the temperature, I walked around the greenhouse and saw that Lao Zhang only pays attention to the yield, this variety has a strong ability to produce melons, and there are more melons in one section, but the plant growth is poor, the fertilizer and water are not on the top, and there are many deformed melons that have not been removed, which will also affect the growth of normal melons.

Cucumbers will stop growing if they don't get enough nutrients during the growth process, and there are many reasons why cucumbers turn into melons, but the first one is temperature. The normal temperature of cucumber growth is 25 30 during the day and 13 18 at night.

It is a yellow leaf disease, and the soil is damp with more water

Cucumbers always wilt when they don't grow big, there are many reasons, such as insufficient fertilizer, insufficient light, insufficient water, etc., if you want cucumbers to grow straight and long, you have to fertilize well.

Cucumber has a shallow root system, so it should be cultivated in humus loam soil rich in organic matter and good air permeability.

The soil should be mildly acidic to weakly alkaline. It can be applied with rooting agent and Yanwo biological fungus.

Seedling fertilization: use Yanwo water-soluble fertilizer, fully and evenly.

If you find that there is a lack of fertilizer at the seedling stage, you can use Yanwo potassium dihydrogen phosphate foliar fertilizer and spray it on the foliage. It is conducive to cultivating strong seedlings.

Plantar fertilizer: Generally, the roots enjoy rooting agents and Yanwo biological fungi agents, which are conducive to slowing down seedlings.

Soil top dressing: 5000 kg of cucumber per mu, from planting to the end of harvesting, a total of 8 10 times of top dressing. The first top dressing after planting slow seedlings was mainly water-soluble fertilizer.

In the peak period of vegetable melon, increase the number of top dressing. It is conducive to promoting the normal development of fruits and the healthy growth of plants.

Cucumber is a common vegetable in life, because it is rich in nutrients and has the effect of improving the body's metabolism, so it is often used in people's diet, and even raises cucumbers at home, but many people have encountered the problem of cucumbers shrinking before they grow up.

1. What should I do if the cucumber shrinks before it grows.

Cucumber in the process of growth should be reasonable fertilization for it, if long-term do not fertilize or lack of nutrients, it will also cause it to grow small on shrinkage, generally speaking, cucumber growth period is recommended to apply fertilizer to it every 7 10 days, but also appropriate spraying of foliar fertilizer, which is more conducive to its growth and maturity.

If the cucumber does not grow up and shrinks, it may also be infected with pests and diseases, in this case, we can only pull out the more seriously damaged cucumber to prevent the spread of the disease, and at the same time should spray it with some fungicides.

Second, why did the cucumbers wilt.

Cucumbers are grown in many families, and the reason why they wilt before they grow is that they wilt. It is mostly caused by lack of water, it must have sufficient water during the growth period, and its growth will be hindered by high temperatures. If the lack of nutrients will also lead to this situation, we should fertilize it regularly during its growth period, if the cucumber is infected with pests and diseases, then its fruit will not grow large and shrunk away, it is recommended that in this case it must be sprayed in time.

3. How to raise cucumbers to grow well.

The root system of cucumber is relatively shallow, and organic fertilizer should be used as a base in cultivation to improve the air permeability of the soil and the supplement of fertilizer. The soil nutrient absorption capacity of cucumber is lower than that of melons, so it is necessary to "eat less and eat more meals" in the top dressing. The demand for water in the fruiting period is the same, and the fertilizer is water-soluble fertilizer.

Start from the stems and leaves. During the growth period, according to the growth situation, it is best to prune and pinch the tips in the afternoon, and keep 1-2 leaves after the melon is set to pinch the tips to remove the tendrils to reduce unnecessary nutrient consumption.

Temperature control. Generally, the photosynthesis is 25-30, the temperature above 32 cucumber respiration increases, the conversion rate decreases, more than 40 will fall flowers, photosynthesis declines, is not conducive to fruit growth.

Pest control. Proper spraying of pesticides ensures the healthy growth of cucumber plants, thereby increasing yields.

The temperature of the surrounding environment, the fertility of the soil, pests and diseases, etc. will all be affected.

The reason for the high probability is that the fertilizer is insufficient, the cucumber grows quickly, and the seedlings grow while receiving the melon, which consumes more fertilizer and causes the middle and late flowering to not receive the melon. Or the soil is dry and water-deficient, cucumber consumes a lot of water in a lifetime, dropper cultivation is about 200 square meters per mu, the number of leaves increases in the middle and late stages, the water consumption of transpiration is large, and the lack of soil water causes melon root diseases and pests will also cause melon. It is very simple to grow cucumbers that can continue to bear fruit on the balcony, cucumbers are a kind of climbing vine melon fruits, suitable for raising in the yard to set up brackets, raising them on the balcony can allow it to climb on the fence, set up some small brackets for it, and it can continue to bloom and bear fruit.

Some friends will encounter only flowering and not bearing fruit, the common reason is because the male flowers that have just grown out, and then the female flowers will grow, the male flowers will not bear fruit, they are only as pollinating flowers, and the stalk of the female flowers will have a small melon, which is very different from the male flowers. The reason for the high probability is that the fertilizer is insufficient, the cucumber grows quickly, and the seedlings grow while receiving the melon, which consumes more fertilizer and causes the middle and late flowering to not receive the melon. Or the soil is dry and water-deficient, cucumber consumes a lot of water in a lifetime, dropper cultivation is about 200 square meters per mu, the number of leaves increases in the middle and late stages, the water consumption of transpiration is large, and the lack of soil water causes melon root diseases and pests will also cause melon.

There can be a variety of reasons why pro-cucumbers don't grow and wilt when they don't grow well, and here are a few possible reasons:1Water shortage:

Cucumbers need plenty of water to grow, and if they lack water, the fruit will not grow much and eventually wilt. Therefore, it is crucial to keep the soil moist. 2.

Malnutrition: Cucumbers need adequate nutrients to grow properly. If the soil is deprived of nutrients, or if the plant is attacked by pests and diseases, the cucumber fruit will not grow much and eventually wilt.

3.Too high or too low: Cucumbers need the right temperature to grow, if the temperature is too high or too low, the fruit will not grow much and eventually wilt.

4.Pollination does not sell full covering: cucumbers need adequate pollination to grow properly.

If pollination is insufficient, cucumber fruits will not grow much and eventually wilt. Therefore, in order to solve the problem that the cucumber fruit does not grow well and the middle is wilted, it is necessary to carry out watering, fertilization, pest control and pollination measures in time, and maintain suitable temperature and humidity conditions.

Hello, cucumbers don't grow much, there are the following reasons.

1. Insufficient water, cucumber growth period is relatively long, it generally takes 2 to 3 months from sowing to flowering and fruiting, and when the cucumber blooms and bears fruit, it has reached the high temperature weather, at this time the cucumber needs a lot of water, and the lack of moisture will cause the cucumber to grow small.

2. Insufficient fertilizer, cucumber growth period is long, in addition to putting plantar fertilizer, top dressing is also needed in the later stage, without sufficient fertilizer, cucumber is not big.

3. There are too many fruits, cucumbers grow too well, and too many fruits, which will cause cucumber malnutrition, and cucumbers will not grow big, so we need to give up some cucumber fruits.

4. The seedling stage is long, and the cucumber seedlings should control the water in the early stage to prevent the growth, and the roots can absorb and transport more nutrients to the end of each branch in the later stage when the roots are long and firm, and the cucumber fruits can absorb more nutrients. If the cucumber seedlings have slender roots and cannot transport sufficient nutrients, the cucumber will not grow much.

One fruit per leaf, it does not grow after sitting in the womb.

It's been ten days and it's still like that, fetal melon.

Hello, it is recommended that you prune some and keep 3 4 leaves and one fruit.
