What should I do if the beans don t bloom and only grow vines?

Beans are a vegetable that I like to eat very much, and every summer we will grow some in our yard to eat by ourselves, which can be mixed cold or fried, which is an indispensable delicacy in summer. Then there will be many problems in the process of planting beans, such as the color of the beans is white and difficult to sell, the beans have diseases and pests, the beans do not bloom and bear fruit, etc., which plague vegetable farmers all the time.

So like the question raised by the landlord, what are the reasons why the beans only grow vines and do not bear fruit? My analysis is as follows:

The weather temperature is too high, which leads to pollen inactivation, which affects pollination and ultimately leads to low fruit set rate of carob. In the process of bean planting, if the amount on the plant is relatively small, the nutrients will be ** to the branches, and eventually there will be a situation of overgrowth.

Nitrogen fertilizers are applied too high, such as urea or high nitrogen fertilizers. The manifestation of nitrogen fertilizer in plant physiology is to promote plant growth. In the process of nitrogen fertilizer uptake by carob plants, the uptake of potassium and phosphorus fertilizers will be inhibited, resulting in the phenomenon of long branches and few flowering and fruiting.

The reason for the variety. In the process of bean planting, how to choose a good variety is crucial. If the quality of a variety is relatively poor, it will lead to weak seedlings and susceptibility to diseases, and even the phenomenon of not flowering and fruiting, etc., it is possible.

Pests and diseases can cause flower and fruit drops, such as thrips, red and white spiders, weevils, green blind bugs, etc., which will affect the growth of plants and cause flower and fruit drops. Then in the absence of reproductive growth, vegetative growth will dominate, so there will be a phenomenon of growth.

So in view of the current situation, the beans have already grown, what are the rescue measures?

Spray the anti-wang agent to control the anti-wang. Bayer's diatristine (oxystrobin) can be used. tebuconazole) can not only treat the disease but also play a role in controlling the prosperity.

When spraying for the growth point of the beans, do not spray again, it will have a certain effect of controlling the growth. Pests can choose thiamethoxam, and mites can be controlled with bifenazide.

Foliar sprays of phosphorus and potash and boron. On the one hand, it promotes the flowering of carob, and on the other hand, it promotes fruit set. Spraying potassium fertilizer after fruit setting can be beneficial to the rapid expansion of carob and play a role in the self-regulation of carob plants.

Try not to water the beans during the flowering period, otherwise it will easily cause flower drop.

The first may be that there is not enough light and sufficient light is needed to promote its growth. The second possibility is that the amount of water is not enough, and it needs to be watered regularly to prevent dryness. The third may be that the nutrients are not enough, and regular fertilization is needed to provide him with more energy to grow.

Fourth, it is necessary to spray drugs regularly to prevent pests and diseases.

It is possible that the seeds of carob are not very good and cannot be developed well; In addition, because the temperature is relatively low, the humidity is not enough. If there is a lack of nutrients, or the wet fertilizer is not right, it will also be the same, so you need to plant them in a greenhouse, maintain the right temperature, and apply organic fertilizer to the soil.

Improper sowing period, the influence of pests and diseases, too much nutrition in the early stage of growth, and bad weather during the germination and differentiation period will affect the pods of cowpea.

The most suitable temperature for cowpea growth is between 18 and 28 degrees, so the sowing period of cowpea is particular, and sowing in the season when the temperature is too high or too low will cause cowpea to stop growing, or too few pods. Cowpea itself has serious pod loss during the growth process, and few can be retained. If the sowing time is not right, and the pods fall even with a low pod setting rate, the final yield of cowpea will be greatly reduced.

In summer, cowpeas are seriously infested by pests and diseases, and pests such as tobacco worms and cowpea borers can damage the flower buds and pods of cowpeas. Pesticides can be used at this time, but in moderation. And can trap and manually kill pests as much as possible do not use pesticides, excessive pesticides will be absorbed by cowpeas will remain in the cowpea celery stuffy cherry part, affecting cowpea flowering and fruiting, and at the same time harmful to the human body.

In the early stage of cowpea growth, many people are worried that the plant growth nutrients are not enough, and artificial nutrition supplementation leads to cowpea absorbing too much nutrients during the growth process of early flowering and growing too vigorously. It seems that the cowpea with lush branches and leaves has actually entered a stage of uncoordinated growth at this time, and the leaves and flower pods compete for nutrients, and the leaves are too large and the number is too large, and the flower pods will fall off the flowers and pods if they can't grab the nutrients.

Therefore, when fertilizing plants in the early stage, the amount should be controlled and not too much. If you see crazy growth, you should remove it in time, so that the cowpea plants are reasonably distributed and will not rob each other of nutrients. Cowpeas are grown one after the other, and they should be picked in time to avoid robbing the pods of nutrients.

The flower bud differentiation period of cowpea is particularly important, when the temperature is too high or too low, the air humidity is too high, and the growth is too dense and the light is insufficient, which will affect the growth of cowpea. In the face of this kind of covering, you can choose to manually intervene in the environment, choose fertile soil to cultivate strong seedlings alone, and improve the ability of cowpea plants to resist the harsh environment.

The moisture in the soil is not enough, the fertility of the soil is not enough, the sunshine time is insufficient, there is not enough photosynthesis, there is no nutrient composition in the soil, and the nutrients cannot be absorbed coarsely.

It may be that the soil is not suitable, the seeds are not of good quality, or there is not enough moisture, or there may be a lack of fertilizer, or the temperature is not suitable.

It may be due to insufficient light conditions, insufficient soil fertility, or too high temperature, which leads to flower fall.

It may be caused by a lack of vitamins or nutrients, and it needs to be adapted at a fixed time, so that you can hurry up the cauliflower.

1. Watering management, after the carob seedlings are all out, the transplanted ones should be watered once according to the soil conditions after the seedlings are slowedSince then, they have begun to control water and fertilizer, and have carried out cultivating and squatting seedlings. During this period, if there is a lot of water and fertilizer, the plants are easy to grow, the pod-setting position will also be increased, the flowering will be less, and the pod-setting will also be reduced, resulting in a decrease in yield.

2. Top dressing management, after the carob plant enters the flowering and podding stage, it is combined with watering for top dressingAbout 15 kg of ammonium sulfate per mu each time, or about 5 kg of potassium sulfate, 5-10 kg of urea, or 5-10 kg of compound fertilizer each time, can effectively promote the flowering and poding of carob.

3. Pruning management, creeping beans can be managed by wiping down the buds, beating the waist branches, stuffing the tips of the group, and topping the main vines, which can effectively promote the formation of beans.

Bean pest control

In the scabbing stage of the middle inflorescence of the beans, it is necessary to water once in about 10 days, control the amount of watering, and carry out top dressing after watering. The scabbing stage of the lower inflorescence should be watered once about 15 days, and the fertilization of diamine phosphate should be carried out. Farmers need to strengthen field management, maintain light transmission and ventilation in the field, and achieve rational planting, rather than planting in large quantities and intensively.

In addition, diseased fallen leaves need to be removed in time, which can reduce the spread of diseases. In the early stage of the disease, farmers can also choose to use pesticides, such as 65% zeb wettable powder 500 times or 75% chlorothalonil wettable powder 600 times, etc., which can effectively prevent the occurrence of pests and diseases through uniform spraying.

This needs to be topped, that is, the top of the beans is pinched off to avoid the plant growing too vigorously.

1 reason. Some carob varieties have requirements for the length of sunshine, so the sown carob seeds must be suitable for local planting, and foreign varieties cannot be blindly introduced.

2. High temperature during the flowering and poding period.

Beans are thermophilic, have strong heat resistance, and are not resistant to low temperatures, and the best suitable temperature for growth is 20-25 degrees, and the suitable temperature for flowering and pod-setting is 25-28 degrees.

Use sterilized scissors to prune the beans and beat the leaves. After pruning, timely supplement nitrogen and potassium fertilizer to promote the growth of plant rhizomes, appropriate watering, and keep the soil moist. Pay attention to the prevention and control of pests and diseases.

The water and fertilizer nutrients are too sufficient, causing the plants and vines to grow wildly and grow wildly, so they do not enter the reproductive growth for a long time, and they have been staying in the vegetative growth link, and they cannot bloom. If you plant too early in the open field, the temperature is relatively low or the spring cold is suddenly inhibited, and if you plant too late, you may not be able to bloom if you encounter high temperature during the flowering period. If you use too much nitrogen fertilizer, you should apply more scale fertilizer and spray some growth regulators.

It may be because the conditions of light and mold illumination are too poor. It could also be because the temperature is too high. If the light is too dry, then the light conditions should be changed. There may also be a lack of calcium boron. Adequate boron-calcium fertilizer should be known and supplemented before the beans bloom.

It may be caused by the low temperature, but the rolling energy is due to frost, or it may be that the sunshine bending sensitivity is not particularly strict, and the temperature of the buried branches is relatively humid, which may be that the soil is more acidic. The soil can be changed, and the temperature of the breeding can be changed, and attention should also be paid to keeping warm.

It may be caused by the variety, or it may be caused by the lack of pension, pay attention to watering, pay attention to fertilization, and pay attention to the density of planting.

1. Cut the long vine short: To solve the problem that the beans do not bloom, it is necessary to cut the vines that are too long to grow short. 2. Reasonable fertilization

During the growth period, phosphorus and potassium fertilizer should be applied 2-3 times to reduce the amount of nitrogen fertilizer. 3. Drainage and stain reduction: dig ditches and loosen the soil in the rainy season to discharge stagnant water.

4. Prevention and control of pests and diseases: cut off the diseases and insects of carob, sell them to destroy the branches and leaves, and spray carbendazim.

1. Cut the long vines short

At this time, you need to prepare sharp and sterilized scissors to cut the branches that grow too long, so that the nutrients are concentrated on the flowering branches, and the dense branches of the beans should be thinned to improve light transmittance.

2. Reasonable fertilization

Beans need sufficient nutrients in the flowering process, when breeding beans, if too much nitrogen fertilizer is applied, too little phosphorus and potassium fertilizer is applied, it will lead to the plant can not carry out flower bud differentiation, it is necessary to reduce the amount of nitrogen fertilizer, and to change the top application of phosphorus and potassium fertilizer 2-3 times, so that the beans can flower quickly.

3. Drainage and stain reduction

Beans do not bloom and only grow vines, you need to control the frequency of watering, it is best to water once a week when there is less rainfall and the soil is dry, and in the rainy season, you need to dig ditches so that the stagnant water can be drained quickly, and you need to use a hoe to loosen the soil, which is conducive to the growth of the root system of the beans.

4. Prevention and control of pests and diseases

When cultivating carob, it is necessary to cut off the branches and leaves of the plant with serious infection and disease to avoid further aggravation of the situation, and to spray carbendazim or chlorothalonil once a week to promote the healthy growth of carob, and after the beans flower, they need to be manually pollinated to improve the fruit setting rate.

The reasons why carob seedlings do not grow vines may involve the following:

1.Weather temperature: Changes in weather temperature can lead to pollen inactivation, affecting pollination, and ultimately resulting in low fruit set.

2.Nutrition**: If the nutrients** on the plant are insufficient, it may cause the carob seedlings to not grow vines. For example, if nitrogen fertilizers are applied too high, such as urea or high nitrogen fertilizers, it may inhibit the uptake of potassium and phosphate fertilizers by plants, resulting in long branches and little flowering and fruiting.

3.Variety quality: If the selected varieties are of poor quality, it may lead to weak and susceptible seedlings, or even non-flowering and fruiting.

4.Insect pests: such as thrips, red and white spiders, weevils, green blind bugs and other insect pests will cause flower and fruit drops, which will affect the growth trend of plants and cause the phenomenon of flower and fruit drops.

5.Planting density: If the beans are planted too intensively, it may lead to fierce competition between plants, limiting the climbing and landing, entering a competitive low growth state, and not producing vines.

In view of the above reasons, the growth of carob seedlings and the generation of rattan can be promoted by improving the planting environment, selecting varieties suitable for hail and hail, reasonable fertilization, controlling insect pests and adjusting planting density. If the above methods still cannot solve the problem of carob seedlings not growing vines, it is recommended to seek help from professionals.

Beans are edible plants that usually need to climb vines to grow. However, some carob plants do not produce too many vines, but grow relatively short, making it difficult to cling to the surrounding supports. This phenomenon of carob not growing vines does not happen by chance, but has its biological reasons.

First of all, the fact that beans do not grow vines may be related to their species. There are many types of legumes, and each variety grows differently. Depending on the variety, the beans may choose long vines or no vines.

In addition, different environmental factors can also affect the way the carob plant grows. For example, if the beans are exposed to insufficient sunlight for a long time, they may choose not to grow vines, which can make it easier for the beans to get full sunlight.

In addition to this, the reason why the beans do not grow vines may also be related to the cultivation method. If the beans are planted too intensively, the competition between them will be fierce, resulting in limited growth and difficulty in climbing and landing. At this point, the carob finger plant may enter a competitive low growth state and do not produce vines.

In general, the reason why beans do not grow vines is not singular, and it may be related to aspects such as species, environment, and cultivation methods. For people who cultivate carob, it is necessary to choose suitable varieties and cultivation methods according to the specific situation, so as to obtain better growth results.
