Tomatoes are particularly badly growing, what could be the cause?

The tomato plant grows vigorously and looks very good, but the nutrients are used in the growth of the plant, so that the supply of nutrients for the reproductive growth of the tomato is insufficient, the growth is reduced, the fruit setting rate of the tomato plant is low, and the nutrients are not allocated.

When tomatoes are planted in summer, there is generally sufficient water and fertilizer, and tomatoes must be broken every three or five times. When our farmers here grow summer tomatoes, they have green hands every day! It's all left over from the time of breaking the stick!

Partial application of nitrogen fertilizer. Tomatoes have more fruits and large yields, and naturally need more fertilizer nutrients, but if the corresponding fertilizer is not applied in some growth periods of tomatoes, it may cause partial fertilization. Spray the first time at the early flowering stage, and spray Jinkede "Titanium Yang" (or Meilanda titanium fertilizer) at the budding stage, full flowering stage, and first ear fruit expansion stage for the second time after 15 days, so as to improve the yield and promote early ripening.

When the root system of the plant is damaged due to root soaking, root burning, etc., the ability to absorb nutrients will be weakened, and the tree will become very weak. In this case, blind fertilization can only be counterproductive.

If there are more cloudy days, the light time in the greenhouse can not reach the best time, and the seedlings can not get enough light when they grow, then there will be some bad phenomena. Tomato growth needs a suitable temperature, so we can artificially increase the temperature, we can use greenhouse warming facilities, or use thermal insulation cover and reflective film, etc., while increasing the temperature at the same time, we should also strengthen the light.

<>Before sowing tomatoes, our farmers should go to the regular agricultural material store to buy the seeds of the current year, and choose varieties with higher purity, high germination rate, strong disease resistance and better fruit shape to obtain high yield.

It may be due to the temperature, too low a temperature will affect the growth of tomatoes. Take care of the problem. Lack of adequate nutrient supply, amount and frequency of watering, etc.

Caused by malnutrition, so when the tomatoes bear fruit, you can apply an appropriate amount of top dressing, so that the tomatoes can better absorb nutrients and thus produce better fruits.

I think it may be due to the lack of fertilizers and various nutrients. So it's not good to grow. You should add some organic fertilizer and farmhouse fertilizer, so that the nutrients are more abundant, and the water and soil structure is also very stable, and it will grow well.

Tomatoes grow a lot, and they have a high yield, so they need more fertilizer. If you don't apply enough organic fertilizer to it, and use too much nitrogen fertilizer, it will inevitably cause the vigorous growth of the plant and the deviation of nutrients.

It may be that the nitrogen fertilizer is applied excessively, but it can be properly dried, combined with the overall technology to pinch off the top buds. Overnutrition can affect reproductive growth. Less nitrogen fertilizer and more organic fertilizer, phosphorus and potassium fertilizer, flowering in 24 days, will promote fruiting.

This is a very common problem caused by tomatoes growing too fast. Proper control of overgrowth of tomatoes can lead to natural results. This is because vegetative growth is too vigorous and overgrowth needs to be controlled.

Too much nitrogen fertilizer, not properly pruned, will make tomatoes grow vigorously but not bear fruit.

Too much fertilization leads to too fast growth, and the shoots and terminal buds are not sorted in time. Mainly before flowering and fruit setting, in the case of too much water and fertilizer, especially too large nitrogen fertilizer, high plant density and low temperature, it is necessary to dip the flower with tomato juice to set the fruit. Tomatoes grow thick and tall, but do not bear fruit.

In fact, in rural areas, many people who grow tomatoes will encounter this situation, but they don't know the reason. They can only be anxious and even continue to fertilize and water. So, what is it about the tomato tree that grows thick and tall, but does not bear fruit?

First of all, from the topic of "tomatoes grow thick and tall", it is obvious that tomatoes grow luxuriantly. It is because the tomato grows thick and tall that it inhibits the reproductive growth of the tomato tree, resulting in no flowering and no fruit. This is caused by over-fertilization and watering, especially large amounts of nitrogen fertilizer applied to tomatoes.

Secondly, the chosen tomato varieties are not suitable for local cultivation. Tomatoes still like light. When planting in the open air on the balcony, it is slightly shaded in summer to prevent leaf wilting due to too much light.

When the tomatoes were planted in the first year, they were thrown directly on the open-air balcony without any shade. The leaves always present dry tips, which affects the photosynthesis of the plant. Later, when it comes to planting, it will be a little shaded in the summer, which is much better.

If the breeding environment is not well lit, the tomato branches and leaves will grow in vain and look lush. In fact, the longer and thinner the foliage, it will affect the differentiation of the flower buds, resulting in little or no tomatoes. Growing tomatoes on the balcony in a breeding environment with as much light as possible not only facilitates the photosynthesis of the leaves and promotes growth, but also makes the tomato plants grow stronger and is conducive to flowering and fruiting.

When the tomato plant grows quickly, the leaves turn dark green to light green, the internodes of the plant become longer, and the tomato seedlings do not bloom for a long time, or after flowering, the tomato fruit setting is not seen. We need to know that it may be because the tomato seedlings are growing vigorously. Then we need to carry out the necessary control to promote the growth of tomato seedlings.

1. Water control and fertilizer. Because it is now the rainy season, it often rains, which causes the tomato seedlings to grow faster. For such a situation, we must do a good job of drainage, cultivating and reducing humidity. And when it comes to the flowering and fruiting stage of tomatoes, reduce the application of nitrogen fertilizer.

2. Sprinkle plant ash, or increase phosphorus and potassium fertilizer. We often use plant ash in rural areas to control prosperity, although the effect is average, but it is cheaper. After applying some phosphorus and potassium fertilizers, it helps to inhibit the vegetative growth of tomato seedlings and change to reproductive growth.

Overwatering or over-watering leads to vigorous growth, poor flowering and fruiting; Excessive application of nitrogen fertilizer and insufficient phosphorus and potassium fertilizer; The cultivation density is too large and the light is insufficient. It can be solved by selecting varieties that are not easy to grow, reasonable fertilization and watering, timely pruning, and erection of frames to make ventilation and ventilation good.

I think this may be caused by too much fertilization, so excess nutrients also have a great impact on tomatoes.

When growing tomatoes, there are times when tomatoes don't grow well. The reasons for this and how to deal with it are as follows:

1.Breed reason. , some varieties have their own small fruits.

Some varieties do not vary much in size between the individual fruits, while others are suitable for long-term harvesting and can bear fruit up to 17 to 20 units, while this type of seed is more expensive. In ordinary tomato varieties, each fruit is smaller than the previous one, and the top fruit is smaller.

2.Fertilizer causes. The lack of various growth elements in plants will cause the fruit to become smaller, and the lack of magnesium, manganese, boron and other elements will also affect the size of the fruit, and improper fertilization will also affect the size of the fruit.

For example, excessive application of diammonium phosphate fertilizer will cause phosphorus poisoning and the fruit will become smaller; Excessive application of potash at one time will also cause yield reduction; Too much boron fertilizer can also make the fruit smaller. Excessive use of nitrogen fertilizers, lack of medium and trace elements, or excessive application of certain medium and trace elements, will result in small fruits. It is recommended to use organic fertilizer with microbial fertilizer for tomato base fertilizer, which can supplement the organic matter content in the soil and increase soil permeability.

3.Cultivation method reasons. Improper cultivation management can also cause tomatoes to not grow well.

For example, there is no erection, which causes the plant to lodging; or the soil is dry and water-deficient, and the fruit cannot expand normally; There is also hormone poisoning, which is the most common cause of fruit size. The main reason is that when the hormone is used to point the flowers, each layer of flowers, the hormone accumulates a little, and the fruit is affected after the 3 or 4 fruits.

4.The weak root system of tomatoes may also cause tomato fruits to grow small, so after transplanting tomatoes, use microbial agents to irrigate the roots to promote the growth of tomato roots and promote root nourishment.

Coping methods:1Choose the right breed. For varieties where each fruit is smaller than the previous fruit, it is mainly used for cultivation with a short harvest period, generally pinching the tip after 3 or 4 fruits, and leaving 3 4 fruits per panicle.

2.Scientific fertilization. In addition to formula fertilization, nitrogen fertilizer needs to be applied in time to ensure nutrients during the flowering and fruiting period.

Starting from the first panicle, 20 25 kg of nitrogen fertilizer can be applied per 667 square meters (mu), combined with potassium fertilizer, to ensure the normal growth of tomatoes.

3.Proper watering and dotting. In summer, when the temperature rises and the evaporation is high, the watering interval needs to be gradually shortened, and the nitrogen fertilizer should be applied in small quantities and many times. If there is a situation where the fruit becomes smaller due to dotted flowers, 3 4 fruits per point should be treated with gibberellin 1 time.

The fruit of tomatoes does not grow much, because the land is not fertile enough, there is no compound fertilizer urea, there is no nutrition, and the nutrients cannot be absorbed, resulting in the fruit not growing large.

Another reason is that there are large and small varieties of tomatoes, and you may plant small tomatoes, fruit tomatoes, no need to fry, just eat them as fruits.

You'd better look for an experienced vegetable farmer to see what the two reasons are.

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.

Does the temperature problem affect the pollination of tomatoes? Tomatoes like temperature and sun, but they are afraid of continuous high temperatures, and at the same time, they are also afraid of ultra-low temperatures, especially in the flowering stage, which is more sensitive to temperature. In particular, the temperature is pursued 3 to 5 days before flowering, on the day of flowering, and 2 to 3 days after flowering.

When the temperature is higher than 35 or less than 15, it is not conducive to plant growth and development and flowering and fruit setting, and the most suitable temperature is 20 30 in the daytime and 15 20 at night. In the hot summer and the harsh winter, it is common for the flowering to slow down and the flowers to fall off the fruit, which is caused by the temperature.

Temperature discomfort and hindered insemination by pollination will cause flowers to fall after flowering and harm fruit set. Therefore, in the production process, it is necessary to understand the hazards of temperature, and preventive measures must be adopted to prevent it. Does the problem of light cause the growth and development of tomatoes to be hindered?

Tomatoes are sun-loving crops that require more time in the light. Many kinds of tomatoes can grow and develop vigorously under 11 13 hours of sunshine, and the flowering conclusion is early, but the sunshine is weak, which causes less nutrient accumulation of plants and is easy to cause a lot of flower and fruit drops. Tomatoes germinate without light, but gradually from the seedling stage until flowering and ripe picking, there is a rule that there will be plenty of sunshine.

If there is not enough light during the flowering period, pollination and insemination are not good, it is very easy to cause flowers to fall, and of course, it will not bear fruit. Is the problem of moisture causing tomatoes to fall all over the ground? In the process of tomato planting, the soil moisture is very high, generally the air humidity of the soil layer is 65 80%, but the relative humidity of the air is low, only 45 50% can be.

If the soil moisture content is too low or too low, it will affect the flowering and fruiting of tomatoes, <>

In particular, the relative humidity of the air is the most harmful, when the relative humidity of the air is too large, it will cause pests and diseases, and it will also prevent normal pollination, and it will also cause only flowering and not the last situation. Therefore, in the production process, when only flowering is not final, it is necessary to find the cause from multiple levels such as temperature, moisture, light, and nutrients, and take corresponding prevention and control measures after finding the reason. It should be desuperheated and cooled, and it should be heated up; the watering of the watering, the drainage of the drainage pipes; The supplement vitamins are supplemented with nutrients.

The planting process is not easy, according to their own conditions and work ability, do a good job in the prevention work, and make every effort to reduce the loss to the ideal state.

The high temperature of tomatoes in the flower bud differentiation period of Liangyuan file will affect the normal differentiation of flower buds of tomatoes, and the inflorescence abortion and fruit failure to point or fail to complete the normal pollination and cracking row will occur, and the flowers will not be dotted or the fruit development will not be normal.

It may be that there is no timely watering, or it may be that the choice of fertilizer is not appropriate, and sometimes the choice of fertilizer with other elements may affect the result.

This is due to the imbalance of nutrients, and nitrogen fertilizer is used more, so this situation occurs.

Tomatoes do not turn red, mainly for the following reasons:

Planting density

The family grows tomatoes every year, and a pattern has been found in the planting process, that is, if the tomatoes planted are too dense, the tomatoes will be green and not red. This phenomenon is especially aggravated when it is constantly rainy. This is mainly because tomatoes are planted too densely, which will affect their ventilation and light transmission, and if you add constant rainy weather, the color of tomatoes will be slower, so some will not turn red.

Therefore, special attention should be paid to the density when growing tomatoes.

Temperature reasons

Whether tomatoes can turn red or not is actually related to the light level and temperature. As mentioned before, if the planting is too dense, the light level will not be enough to affect its coloring. And the temperature will also affect the coloring of tomatoes.

Some people think that the higher the temperature, the redder the tomatoes will be. In fact, this is not always the case, although temperature plays a very important role in the coloring of tomatoes, it is not the only factor. When the tomatoes enter the ripening period, they will metabolize a kind of lycopene, and when the lycopene will become more and more, the tomatoes will gradually turn red, which indicates that the tomatoes are slowly ripening.

But the best temperature for lycopene formation is between 18 and 26. If the temperature is too low or too high, it will affect the formation of lycopene, and when it is higher than 32, the formation of lycopene will be blocked. In the summer, there are some days when the temperature is generally higher than 32, so it will affect the color.

Water and fertilizer management

This is also a very important factor, tomatoes are a fruit and vegetable that bears fruit while flowering, and its growth cycle is long. Therefore, a lot of nutrients and nutrients will be consumed in this process, and if the fertilizer efficiency in the soil is not enough, and it has not been filled immediately, especially the deficiency of some important nutrients, such as boron, calcium, copper, molybdenum, manganese and other factors, it will not be good to color. Therefore, if the tomatoes do not turn red, it is also necessary to consider whether the fertilizer is unreasonable, and immediately fertilize it to ensure that the tomato yield can be increased.
