Why don t cucumbers grown in the open field bear fruit this spring?

Why don't cucumbers grown in the open field bear fruit this spring? Cucumbers can be grown in the open field in the spring**, if in order to avoid the spring cold, you can cover the soil with a layer of plastic film. It is estimated that you did not cover the plastic film and encountered the cold spring, so the cucumber is not easy to bear fruit.

The cucumbers you planted, if you don't get married, they should be too dry, well, your kettle in the morning, it will dry in the afternoon, it's too hard, if you do it, they won't grow.

Cucumbers planted this spring did not bear fruit, probably because they were not pollinated when the cucumbers were flowering.

Due to climatic reasons, cucumber flowers are frost damaged in spring.

You may have planted early in the spring, and he came out and moved all the stamens, so it didn't bear fruit.

Cucumbers planted on the ground this spring. No, it may be that you bought the wrong seeds. If you buy the right seeds. His family still has a lot of fruit. One leaf for another.

Cucumbers that do not bloom and bear fruit can be caused by three reasons. First, improper fertilization. The second is that the pesticide is overdosed, and the concentration exceeds the standard and brings pesticide damage. 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.

Improper fertilization. Excessive use of compound fertilizer makes the concentration of soil solution too high, weakens the absorption capacity of roots, and affects the normal growth of plants. Improper watering.

Watering does not pay attention to weather conditions, and does not analyze the pros and cons of watering according to the law of plant growth. If the influence of unfavorable weather such as cloudy days, low temperature and strong cold snap after watering makes the ground temperature lower than 12, and the relative humidity of the soil is higher than 85%, resulting in cucumber roots, so that the root growth is inhibited, and the growth of the upper part is greatly affected.

The cucumbers planted have a lot of flowers, and the flowers of fruits and vegetables are divided into female and male, and the female flowers need to be pollinated by male flowers to bear fruit, and they are generally pollinated by bees or butterflies, and of course they are all pollinated by hand.

Hello, it may be caused by low temperature, vigorous plant growth, etc.

Prevention method: After the plant bears melon, the amount of nitrogen fertilizer should be reduced, and more potassium fertilizer should be applied to prevent the plant from growing;

When the plant is vigorous, it can be sprayed with drugs such as mequat when the plant grows to 3-9 leaves.

Planting conditions: 1. Soil.

The roots of cucumbers are not deep and have high aerobatic properties, so we should choose thick, soft and permeable soil for planting.

2. Illumination. When planting, the light time is kept at about 11 hours, which is conducive to improving the flowering rate of cucumber female flowers, and when the light time is slightly extended, it can increase the flowering rate of male flowers.

3. Fertilization. The yield of cucumber itself is very high, and it is recommended to add a large amount of fertilizer, especially the amount of basal fertilizer must be sufficient. It is recommended to choose the water-soluble fertilizer of Haihai and Weihai as much as possible, and the best way to fertilize is to sprinkle the required fertilizer in the ground at one time during each land preparation.

Why do cucumbers wilt before they grow?

It is not so easy to grow cucumbers, especially for some novices, if you don't pay attention to some places, you will see the young melons grow, but they will stop growing as soon as they grow a little, and they will slowly dry up. There must be some problems in some places, and some people think that it is not a problem with fertilizer, but in fact, there are many reasons in addition to fertilizer:

First, the variety. There are many varieties of cucumbers, which should be selected according to the local situation, and other conditions should also keep up, for example, some varieties are very good at bearing melons, but at the same time of bearing melons, water and fertilizer must keep up, if water and fertilizer can not keep up, then the cucumbers will naturally not grow well.

2. Temperature. If you want cucumbers to grow well, you must have suitable conditions, for example, temperature is very important, there is a certain temperature difference between day and night, the temperature is about 25 to 32 ° during the day, but at night it is best not to be higher than 20 °, otherwise it will consume a lot of nutrients, resulting in nutrient deficiency, cucumbers are easy to grow small. Therefore, if you are planting in a greenhouse, you should pay attention to controlling the temperature. The temperature is checked during the day and at night.

3. Water and fertilizer. This is also a problem on the one hand, if the cucumber does not grow well, it will feel that the fertilizer is not used well. However, whether it is good or not is related to many aspects, it must be nutritious, but it cannot be prosperous. For example, this nitrogen is really needed but not excessive, if it is excessive, the plant will grow vigorously, and the cucumber will not grow.

In addition, it is necessary to pay attention to a potassium problem, if it is deficient, it will affect the growth of leaves, and it will also affect the growth of cucumbers.

In this regard, it is important to pay attention to balance.

There is also a water aspect, water once when planting, and then don't water it for the time being, so that his root system can be deeper. When the cucumber starts to grow, the demand for water and fertilizer will be greater.

In addition, it is not that the cucumbers that grow can be wanted, such as a vine, which bears a lot of melons, you should pay attention to grooming, otherwise the nutrition is not balanced, and the cucumbers will also not grow well.

Summary. Hello, this year's melon field can be planted with cucumbers in the open air next spring. Cropping is more conducive to soil restructuring and reducing pests and diseases.

Hello, this year's melon field can be planted with cucumbers in the open air next spring. Cropping is more conducive to soil restructuring and reducing pests and diseases.

1. Make full use of soil nutrients and water: the nutrients required by different field crops and the ability to absorb water are different, and reasonable crop rotation can make full use of various nutrients in the soil. 2. Rational use of agricultural resources

Reasonable crop rotation can not only make full use of natural resources, but also make balanced use of agricultural tools, fertilizers, rental slag pesticides, large water resources and capital and other social resources, and can stagger the agricultural season. 3. Inhibition of diseases, insects and weeds: Through the rotation between different crops, the main body of pathogen parasitics can be changed, and the growth of pathogens can be inhibited, so as to reduce the harm.

4. Increase yield: Quiet and reasonable crop rotation can improve planting efficiency and achieve the purpose of increasing yield.

Dear, if my help to you, please give me a thumbs up, thank you!

One of the reasons why budding is not very good is that the temperature is too low. The climate is abnormal, and the temperature is half a month later than usual. The delay in the rise of the temperature will also be accompanied by the delay in the soil temperature, which will inevitably lead to the poor emergence of cucumber seedlings.

Not only is the cucumber seedlings I planted not very good, the next door neighbor brother is a veteran of farming, this year he still planted cucumbers in accordance with the previous season, but also planted in the corner, the relative temperature will be higher, but, planted nearly 20 days before the seedlings emerged, anxious he often went to pick and pull, sometimes there will be buds, and even will pull off the buds. But now it's all gone.

Seeds. In the process of planting vegetables, the selection of seeds is crucial, generally speaking, the germination rate of new seeds will be higher. The old seeds of the previous year or the early years are likely to suffer some damage when they sprout, so in the case of planting cucumbers, try to make the original seeds as much as possible.

In the case of my family's cucumber planting this year, it may be because of the use of leftover seeds, so I don't like to sprout. Soil temperature. The reason why cucumbers refuse to bud may be that the soil temperature is too low, and in the case of planting the amount of cucumbers, it is necessary to pay attention to the weather conditions and temperature.

Tooth induce. Although it is enough to plant cucumbers and choose the method of live broadcast room, in order to ensure its germination rate, delicate cucumbers can emerge as soon as possible, and the germination time can also be reduced according to the method of tooth promotion. Because none of the cucumbers planted before came out, yesterday we bought a new cucumber seed, put it in a cell culture dish to promote teeth, in fact, tooth promotion is very simple, you must put the seeds into the vessel, soak it in warm water, or cover the seeds with a wet rag, put it in a warm place and let it stand for a day, and it will sprout immediately.

Cucumber seeds are some aged seeds, many of which have lost the ability to germinate, and even if they can sprout, germination is the main manifestation of disadvantage, and it will wilt if you are not careful. Under the premise that the soil is too thick, the melon seedlings cannot be arched. Under the premise that the water is suddenly insufficient and the soil filling is too thin, the melon seedlings are very easy to dry out and die with little water.

When the temperature is too low, the germination rate of seeds in the past is basically zero, and it is very rare to succeed in breaking the soil. Therefore, the selection of cucumber seeds is very important for cucumbers.

One of the reasons for poor budding is that the temperature is too low. The weather was abnormal, and the temperature was half a month later than before. Delayed warming, soil temperature also needs to be delayed, which will inevitably lead to poor cucumber seedlings.

The number of watering of melon seedlings should not be too much, if the amount is too large, it is easy to destroy its root growth, and then it will affect the growth of the whole plant. Generally, it is divided into two situations, one is to use less fertilizer, the other is not to top dressing in time, and then the melon seedlings stop growing because of the lack of nutrients. It is conceivable that the more cucumber seedlings bloom, the more nutrients it consumes, so it is necessary to thin the flowers at this time, if the flowers are not thinned in time, it will lead to the cessation of growth of the melon seedlings.

Cucumber is one of the more common ingredients on our table and is loved for its crisp texture. Nowadays, cucumbers can be eaten all year round, but if you want to say that the taste is still the most refreshing and sweet cucumber in spring, when will cucumbers be planted in spring? Follow this article to find out when cucumbers can be planted.

The time to plant cucumbers in the spring

1. The planting time of cucumbers planted in spring is after the local late frost, and the temperature is about 18 degrees, and the planting time of cucumbers in Beijing, Shanhengpao, Tianjin, Shijiazhuang and other places is in late April. In addition, in order to make the cucumber grow better, it is recommended to plant it on a sunny day, and the density of planting can be determined by the characteristics of the cucumber variety planted.

2. Spring sowing cucumbers should be decided according to planting, the general seedling time is about two months, if calculated according to the seedling age, it can be planted almost forty or fifty days before planting. In addition, the length of childbearing age of cucumber is directly related to the method, the seedling is raised at the temperature of the sun, the seedling time is about 50 days, the seedling is about 45 days in the heated greenhouse, and the electric seedling is almost 45 days, so it can be seen that the seedling method is different, and the sowing time of cucumber is also different.

Precautions for cucumber planting

1. First of all, choose a suitable container for sowing, similar to flower pots, wooden pots, plastic boxes, etc., with a depth of about 40 cm is the best.

2. Before planting, soak cucumber seeds with a water temperature of about 55 degrees for about 20 minutes, and then continue to maintain a constant temperature.

3. Sprinkle the cucumber seeds evenly on the prepared cultivation utensils, and then apply thin soil in turn, with a thickness of about one centimeter.

4. When watering, it needs to be watered thoroughly, and the temperature and humidity must be ensured.

5. If the seedlings emerge in summer, pay attention to covering the shade net.

6. Generally, it may take three or four days for dried cucumbers to emerge, and if they are planted after germination, it will be faster. When one or two true leaves come out, transplanting can be carried out.

The above is what this article shares for you about when it is better to plant cucumbers in spring, through this article, it can be seen that spring sowing cucumbers generally start in early March, and you can choose some varieties that are more vigorous and have strong fruiting ability to plant.

Open cucumber sowing is suitable for the right time.

Open-air cucumber refers to cucumber grown outdoors, this vegetable can be propagated by sowing, cuttings and other methods, generally 5-7 days after planting, it can germinate, from seedlings to flowering takes about 80-110 days.

Generally, open-air cucumbers are planted in July and September, because the temperature is stable and the climate is suitable, which is conducive to seed germination, but the specific sowing time should be adjusted according to the local temperature change.

The open-air cucumber sowing method is trembling and royal.

1. Land selection and land preparation.

Open-air cucumbers should be planted in fertile, loose, and convenient drainage and irrigation plots, and the soil should be moderately deepened before planting, and the soil should be prepared to make furrows, and an appropriate amount of base fertilizer should be added to the soil.

2. Plant.

Sow the seeds of cucumbers in the open air, sow 2-3 grains per hole, and then cover the soil about 1-2 cm, water it once, and control the ambient temperature at about 25-30.

Tips and techniques for planting cucumbers in the open air.

1. The planting of cucumbers in the open air also needs to raise seedlings, and the seedlings need to be soaked in 55 water, which can improve the germination rate of seeds.

2. Choose the right variety for open-air cucumber planting, if it is planted in July and August, you must choose cucumber varieties that are resistant to high temperature, rocklogging and disease.

1, autumn open field sowing cucumber is generally in North China and East China, 6 to 7 months is usually the sowing period, 8 to 9 months for the harvest period, autumn sowing cucumber plays an important role in the supply and demand of vegetables after the autumn off-season, 7-8 months is the rainy season and high temperature festival, it is the early growth of autumn cucumbers, to choose those who are relatively strong, the seedling stage to be heat-resistant and the later stage must be cold and drought resistance, disease resistance and other varieties that are not sensitive to long sunshine.

2. Select excellent varieties with strong plant growth potential, high temperature resistance at seedling stage, strong disease resistance, low temperature tolerance during the bulk transportation period after growth, and slightly larger fruit shape. Such as Zhongnong No. 2, Jinyou No. 4, Jinlu No. 5, Jimei No. 4, Jinyou 40, Jinyan No. 4, Jinza No. 4, Jinza No. 3, Ji Cucumber No. 1, No. 2, Xiaqing No. 2, Tangshan autumn melon and other late-maturing varieties in Chong Daliang. Early-maturing varieties are often satisfied too early due to accumulated temperature, and a large number of melons are produced before the stems and leaves have time to grow in sufficient amount, resulting in melon seedlings, uneven plants, and serious deformity of melon strips.
