What to do if tomatoes bear less fruit and have low yield, and tomatoes bear less fruit?

Tomatoes do not bear fruit in flowering, or have less flowering, and have a low fruit setting rate, which is also one of the common phenomena encountered in tomato planting. I have grown tomatoes in greenhouses for several years, and in the management of tomato planting, I still have some understanding of such problems, and the scientific name of tomatoes is tomato. People like to use it as a side dish, such as roasted scrambled eggs with tomatoes, beef stew with tomatoes, stir-fried potatoes with tomatoes, and so on.

Because there is a relatively large market demand, there are many people engaged in planting.

There are two main reasons for the phenomenon of <> tomatoes only flowering but not fruit setting: one is the excessive vegetative growth of the plant, and the other is that the unfavorable natural conditions affect the flower bud differentiation of the plant. The main factors that cause the vegetative growth of the plant are the influence of high temperature, tomatoes are one of the most commonly eaten vegetables in summer, the taste is sweet and sour, and it can also be eaten directly as a fruit, there are many tomatoes planted in the open field in the countryside in summer, but we will find that there are some tomatoes that only bloom and do not bear fruit, so how can we make tomatoes bear fruit?

Calcium is the composition of the fruit cell wall, and calcium can also increase the connection between the fruit and the fruit stalk. If tomatoes only bloom and do not set fruit, it is recommended to spray organic titanium-boron calcium foliar fertilizer from the germination stage. It can effectively supplement boron and calcium, promote fruit flowering and fruit setting, and tomato needs more phosphorus and potassium fertilizers during flowering and fruit setting.

In addition to base fertilizer and water-soluble fertilizer, weekly foliar spraying with potassium dihydrogen phosphate can promote flower bud differentiation and effectively improve fruit setting rate.

The pH of the soil also affects the fruit set of tomatoes, and generally tomatoes are suitable for pH (, it is best to use organic fertilizer to adjust the pH of the soil, one is to increase soil fertility. Second, it can adjust the pH of the soil and improve the soil. Before flowering, sugar alcohol boron, sugar alcohol calcium, and potassium dihydrogen phosphate can be supplemented to promote flower bud differentiation, more flowering, more large flowers, and enhanced pollination ability.

In the young fruit stage and fruit expansion stage, potassium dihydrogen phosphate, calcium and magnesium fertilizer can be sprayed. Boron and calcium are best supplemented at the same time.

1. Tomato needs different fertilizers at various growth stages, nitrogen fertilizer is the main fertilizer at the seedling stage, but it is not advisable to apply too much, so as not to cause growth. When the plant flowers and bears fruit, it is necessary to apply less nitrogen fertilizer and increase phosphorus and potassium fertilizer, which can significantly improve the fruit setting rate.

2. The temperature should be strictly controlled, not more than 30 degrees during the day, and not more than 35 degrees in the summer, so as not to affect the flower bud differentiation of the plant, and the night is generally 12-18 degrees, which should not be too high, so as not to appear the phenomenon of stem length, resulting in falling flowers and fruits. The temperature can be lowered by shading and sprinkling water at high temperatures, and the temperature of the shed can be increased by reducing ventilation at low temperatures.

We must ventilate in time, and water less and carry out top dressing, so as to improve the fruiting rate.

This situation shows that your land fertility is too poor, and the best way is to chase fertilizer twice during the growing period, and the dosage is 80 catties of urea per mu each time.

It may be that the ventilation is not very good and some large leaves can be removed properly, or it may be that the soil is not sufficient and the soil moisture is not enough, which may affect the yield of tomatoes.

It may be because you water too much and the water soaks the roots of the tomatoes, so the yield will be less.

Because the tomatoes are short of water, and the tomatoes are not nutritious, this will make the tomatoes very small.

This may be because tomatoes lack a lot of water during planting, and there is a lack of a lot of potassium fertilizer, so it will be planted very poorly, and the yield is particularly low.

1. Low temperature during day and night. Tomato growth and development for the temperature requirements are more strict, if the temperature of the shed is too small, the night is too high, the respiration of the plant is aggravated, will consume a lot of nutrients, resulting in the fruit does not have sufficient nutrients to grow and develop, so the yield is lower than that of the bird's shed. It is best to keep it between 24-28 degrees during the day and about 10-13 degrees at night, so as to widen the temperature difference between day and night as much as possible and promote the expansion of the fruit.

2. Improper ventilation. When cultivating in winter, we should pay attention to the ventilation method, and after pulling the shed in the morning, you need to close the shed immediately to see the light, and do not immediately release the wind, because the carbon dioxide accumulated in the shed at night is not fully used for photosynthesis. Second, the temperature of the closed shed rises faster, so that the photosynthetic rate will also increase rapidly, or reduce the humidity in the shed, after an hour of carbon dioxide accumulated in the shed is used by photosynthesis, under the condition of suitable temperature, then ventilate the carbon dioxide in the air for photosynthesis and accumulate more nutrients.

3. Low fertilizer application in farmyards. In many areas, farmers prefer to use chemical fertilizers and ignore the application of farm fertilizers, resulting in low organic matter content of soil, serious soil compaction and poor permeability. Generally, tomato planting land needs to apply 3000-5000 kg of farm fertilizer per mu, and at the same time, it is necessary to pay attention to cultivating loose soil, increase soil permeability, promote root growth and development, and lay a solid foundation for plant growth.

Add fertilizer to tomatoes, mix nitrogen and potassium fertilizers, dilute them with water, and spray them on the roots and leaves of tomatoes every day to increase their yield.

The variety of tomatoes can be improved, and seedlings can also be raised in advance, and some water and light fertilizers can be applied appropriately to ensure the yield.

Then you need to fertilize the tomatoes regularly, then you need to water enough every day, and make sure the tomatoes grow in the sun to supplement enough ultraviolet rays.

Be sure to water less, be sure to fertilize more, and be sure to ensure ventilation, be sure to keep the roots breathable, be sure to fertilize more, and prevent insect pests.

Fertilization is the key, before planting, use two tons of organic fertilizer per mu as base fertilizer, and chase urea once during the growth period, with a dosage of 80 catties per mu.

Tomatoes are a very common crop, because the planting conditions are not so strict, so every sowing season, almost every household will plant some tomatoes in their own garden, although tomatoes are not so strict for the planting environment, but the tomatoes planted by each family are not so perfect, there are many farmers who say that the color of their own tomatoes is always not red enough, what should I do, these tomatoes that are not bright enough, basically taste more sour, and not red for a long time, Whether you eat it yourself or sell it, there is no way to get a good feedback, so it is a very important thing to solve the problem of tomatoes not being red. <>

First of all, the cultivation of tomatoes still requires a lot of lightIf the planting density is too high and the leaves are too dense, then the fruit will not be able to get a sufficient amount of sunlightIn the face of this situation, farmers must consider the spacing between tomato plants when planting, and at the same time make appropriate adjustments, the branches and leaves of tomatoes, try to pick those ripe tomatoes every day, so as not to cause uneven distribution of nutrients and affect the growth of other fruits. <>

Secondly,Tomatoes grow normally, and the temperature requirements are also very largeGenerally speaking, tomatoes will secrete lycopene when they are naturally ripe, and when this element accumulates in the tomatoes to a certain extent, the color of tomatoes will become more and more bright red, but if the temperature is not kept at 20 to 25 degrees Celsius, it is not conducive to the secretion of lycopene, so if the temperature is too high or too low, there is no way to get an effective growth of tomatoes. <>

In rural areas, most farmers do not grow tomatoes that are bright red enough, mainly because of thisTomatoes do not need enough nutrients, some elements are missing, light is insufficient, and temperature regulation is not achievedTherefore, we should also consider these factors in the planting process, check the factors in combination with the planting conditions of our own homes, and try to give tomatoes a reasonable growth environment, so as to obtain better fruits.

The main reason is that there is no better supplement of photosynthesis, in fact, it is also because we do not supplement enough nutrients and water when planting, so it will lead.

It may be that the temperature is not very good, or the growth needs of the tomatoes are not met, so they do not look particularly ruddy. You can sprinkle some alcohol on it. The result became particularly red.

It's a matter of temperature, or it's possible that there's no proper fertilization. The density of planting is too large, and so on. These are the things that can cause tomatoes not to be red.

It could be that your fertilizer is not good, so it can't grow completely, or it may be due to the weather.

The daily planting of tomatoes is not done well, or the varieties are not selected well. Some varieties of tomatoes are just not ruddy enough, so they can't do anything. It is necessary to choose the right variety according to the local environment in which it is grown, so that large and red tomatoes can be grown.

As for the planting is not done well, it is generally these three situations. The planting is too dense, the temperature and light are not suitable, and the watering and fertilization are not done well.

First of all, the density of growing tomatoes is too high and it will shade each other, especially in rainy weather. In this way, tomatoes receive light unevenly, and they cannot carry out good photosynthesis, which will naturally affect the development of fruits. Photosynthesis can promote the transformation of tomato plants into inorganic substances under the irradiation of visible light, and promote the growth of plants.

If the tomato is in a place where there is no light for a long time, it will also not be able to photosynthesize. Therefore, when choosing a place to grow tomatoes, the first condition to consider is whether the sun is sufficient.

The second is temperature, and the right temperature is also important for the growth of tomatoes. When tomatoes are ripe, they secrete a pigment that is the key factor in the redder and redder of tomatoes. The most suitable temperature for tomatoes is 17-27 degrees Celsius, and too low or too high a temperature will cause too little pigment secretion.

Finally, during the planting process, the tomatoes should be watered and fertilized regularly, not too much or too little. Since tomatoes are a vegetable that bears fruit while flowering, they also have a long growth cycle. Therefore, when planting, it is necessary to ensure the nutrients and moisture of tomatoes, and to fertilize and water diligently, so as to meet the growth needs of tomatoes.

When fertilizing, it is best to choose fertilizers containing boron, copper, and manganese nutrients, which can promote the color of tomatoes. Tomatoes are grown at too high temperatures, and if you choose the wrong fertilizer, it can damage the root system of tomatoes. At the same time, when fertilizing, remember to constantly turn the soil to improve the air permeability and porosity of the soil, which can also promote the growth of tomatoes and make them more ruddy.

Tomatoes are not rosy enough for several reasons, it can be a lack of light, malnutrition, or insufficient water, all of which can cause tomatoes to not be rosy.

It may be that the light is not enough, the temperature is too low, the lack of nutrients, the lack of fertilization, and the lack of water will all cause the tomatoes to be not rosy enough.

It may be because the planting is too dense, or it may be that the temperature is too high, so it affects his coloring, or it may be that he is short of fertilizer.

The deformed fruit of tomato, also known as metamorphosis, is one of the common physiological diseases of tomato, which can occur in protected areas and open field cultivation, but it is still mostly occurring in winter protected areas. Under normal circumstances, the normal tomato fruit is spherical or oblate spherical, and it is not recommended to plant tomatoes in the summer of high temperature and humidity because of the problem of survival rate. Generally speaking, planting high-yield, high-quality tomatoes need to be from temperature, light, humidity, water tomatoes in the flower bud differentiation period to meet low temperature is an important reason for the formation of deformed fruits, if the average temperature is lower than 8 degrees, it is very likely to produce deformed fruits, if coupled with moisture, the ventilation and light transmission effect is poor, can not meet the full light, nitrogen fertilizer dosage is large.

<> tomatoes have deformed fruits, which are caused by a lack of nutrients. It is recommended to use several foliar fertilizers supplemented with calcium and boron in the early stages of tomato growth. It can effectively prevent the occurrence of deformed fruits.

To reduce deformed fruits, field management must be strengthened. Before and during the differentiation of the first inflorescence, the low temperature below 10C should be avoided, and the seedbed should be avoided from being too wet. In addition, it is necessary to grasp the time and concentration of auxin to treat the flowers, and do not treat it too early.

These types of fruits have more ventricles, so the fruits with more heart suffocation are prone to disordered fruits, in addition to more nitrogen fertilizer and phosphorus fertilizer, and less boron and calcium, it is also easy to produce multi-heart suffocated disorderly fruits, obviously elliptical, eccentric, chrysanthemum-shaped fruits are related to calcium deficiency and boron deficiency. The green skin phenomenon of tomatoes is caused by a viral infection, and the green skin phenomenon is a type of tomato green tendon disease. In planting, production management should be strengthened, and attention should be paid to drug prevention and control.

Tomato green peel is actually a kind of tendon rot, tomato tendon rot is a physiological disease, the main cause of the disease is low temperature and low light environment, carbon and nitrogen metabolism disorders, photosynthesis is reduced, and potassium deficiency caused. It's all too bright. Just keep the leaves on the upper part of the fruit, don't mourn, and block some of the sunlight.

This is the opposite of protected land cultivation. Now those planted out of season can only be said to be in name, and they are no longer tomatoes in the true sense.
