What are the reasons for tomato growth? How should it be controlled?

First of all, tomatoes are long. The tomato seedling cycle is the stem, the dose is too long, the stem is prominent, and the leaves are thin. The plant period is indicated by long stems, the leaves are getting taller and taller, but the flower buds, the flowers are thin, they are prone to falling.

Tomatoes will lead to strong growth in the upper part, consuming a lot of phytonutrients. The roots of the roots are inhibited, and the number of lateral roots is reduced. Plants have reduced water metabolism and mineral metabolism, and the ability of roots to absorb nutrients is reduced.

Nutrient absorption in plants will be over-depleted, which inevitably leads to a decrease in photosynthetic capacity and anti-counterfeiting.

The length of tomato seedlings affects not only the vegetative growth of tomatoes, but also their reproductive growth, and the specific performance is delayed, and the quality of the flower buds will decrease. In the end, the yield and quality of tomatoes will be affected, and the efficiency of greenhouse tomato production will be reduced. The growth factor of spring is the long-term cause of greenhouse soil in spring, with a relative humidity of 80, which is thiofertization; Persistent rainy weather, air humidity often higher than 50 to 60, lack of light, fascinated or poor ventilation.

At the same time, the seedlings are crowded and there is not enough room to grow, and the tomato will be extended. The greenhouse should be allowed to cool the air in time, especially at night when the temperature is too high. At the same time, at a certain temperature, there is more wind, which can reduce the humidity in the shed.

After flowering sitting, we must wear a skirt at the bottom of the skirt, and the lowest temperature at night is not less than 15 ° C. Reduce the temperature difference between day and night and keep it all day. In the summer heat season, the plastic film can be removed, just like cultivation.

**。During production, photographic intensity is often used for light transmittance, and the backwall light curtain is used to prevent seedlings. At the same time, the addition of artificial light source in the greenhouse can effectively inhibit the elongation of the lower embryo, promote the growth of plant roots, and improve the stability of seedlings against bending.

To keep the film clean, try increasing the light intensity and extending the light time. Autumn tomato cultivation is due to high temperatures, especially at night, with a lot of nitrogen fertilizer, and it is not planted in time.

Increase living space. Seedling age grief transplantation control, timely planting to ensure the prevention of seedlings crowding out of the vegetative area. In general, the seedling age of premature tomato varieties is about 60 days, that of cooked varieties is 70-80 days, and that of autumn tomatoes is about 25 days.

It is best to choose sunny weather during the transplant process. The appropriate amount of strategy, timely leakage of leaves, plant ventilation, generally use single or double drying.

Fertilize the water. If the amount of nitrogen fertilizer is insufficient, pay attention to nitrogen, phosphorus and potassium fertilizers. Alkaline fertilizer is sufficient, and the seedlings sit on the first ear fruit, properly watered.

In particular, it is usually not without going into details. After sitting, it will begin to apply fertilizer locally. With deep furrow high grain cultivation, unreasonable measures such as "dry plum" and "multiple transplantation" should not be taken for root growth, which inhibits the normal growth of seedlings, because these measures control the "pulling" growth of seedlings, and in the end only it can cultivate "thin and weak seedlings" instead of gaps.

The main reasons for the growth of tomatoes are too wet soil, too much nitrogen fertilizer, insufficient light, poor ventilation and other reasons. The method is to prepare for planting in advance, control the amount of fertilizer and ventilation.

The main reasons for the growth of tomato plants are too wet soil, too much nitrogen fertilizer, insufficient light, too dense planting, or poor ventilation. The control method controls the seedling age and timely planting. Prepare for planting early to promote seedlings to slow down.

10-30 days before planting, do a good job of land preparation, base fertilizer, cover the roof membrane and skirt of the greenhouse, ditch drainage around the greenhouse, etc., so that the humidity in the shed is lower and the temperature is higher when the seedlings are planted, which is conducive to slowing down the seedlings. The amount of nitrogen fertilizer was controlled, and deep furrows and high furrows were used for cultivation to promote root growth. Prune and beat leaves in a timely and appropriate amount, build a frame, make ventilation and ventilation good, and spray flowers with growth regulators such as anti-falling pigment to promote fruit setting and inhibit excessive vegetative growth.

What are the reasons for the growth of tomatoes in daily life? How should it be controlled? There are many reasons for the growth of tomatoes, the soil moisture is higher at the seedling stage, the relative humidity is mainly at 80%, and the nitrogen fertilizer is applied more, in this fertilizer and water environment, the seedlings are very easy to grow.

Or in continuous rainy weather, the humidity is higher than 50%-60% for a long time, the light is insufficient, and the planting is too dense, which will also cause overgrowth. The prevention method is very simple, as far as possible, through the control of planting density, pruning and other measures, improve ventilation and light transmittance, more light, will naturally alleviate the growth.

There are many reasons for tomato growth, and it may be caused by too much fertilization of the plant. It should be applied once every half a month, the fertilizer should not be too much, and it may be caused by too high temperature, the temperature should be controlled appropriately to keep the ambient temperature at about 25 degrees.

How to operate the tomato control the growth of the man? What do I need to look out for? Control fertilizer and water.

There is enough fertilizer and water at the bottom. In general, do not fertilize and water before flowering and fruit set. Timely spraying of vegetable fruit before flowering, young fruit stage and expansion stage can activate the positive energy of plant ecological growth, broaden plant channels, improve plant water absorption and fertilizer absorption intensity, improve fruit yield and quality, reduce fruit drop rate, reduce the occurrence of fruit cracking, stiff fruit and deformed fruit.

Timely control of seedling age and plants. Strictly control the age of seedlings. For example, the seedling age of the general early-maturing tomato variety is about 60 days, the seedling age of the medium-late maturing variety is about 70-80 days, and the seedling age of the autumn tomato is about 25 days.

Prune and thresh the leaves in a timely and appropriate amount, set up a good shelf, ensure good ventilation, and spray growth regulators such as anti-shedding on the flowers to promote fruit setting and inhibit the growth of excessive nutrients.

Application of the agent. After planting slow seedlings, spray a layer of high cardiac lipid film every 15 days or so to form a polymer film to keep warm and moisturize and prevent bacterial infection. Timely spraying of Jinhuawang No. 3 in the process of flower bud differentiation can assimilate and induce the transmembrane signal conversion of plant cells, forcing a large amount of nutrients from the top bud to reflux, and the inertia advantage of the top bud is rapidly weakened to the cap state.

The main nutrients of the main stem are transferred to the young fruit development system to improve the fruit swelling vitality, avoid leaf hypertrophy, and improve the air permeability in the field.

Control measures for tomato overgrowth.

1。Optimize the provenance. Tomato planting should choose high-quality seeds that are suitable for the local growth environment, suitable for local soil growth, strong resistance and strong resistance to overgrowth as seed sources.

2. The planting density of reasonably densely planted tomatoes should not be too large. Farmers should reasonably arrange the planting density of tomatoes according to the requirements of planting varieties; In general, tomatoes should be planted at a density of 70 cm row spacing and 40 cm plant spacing.

3. Reach the top in time. When the tomato plant grows six layers of branches, you can take the top; Alternatively, when the plant grows to 70 cm to 80 cm, it needs to reach the tip in time to convert nutrients into reproductive growth.

4. Reasonable fertilization requires a large amount of nitrogen fertilizer for the early growth of tomatoes, but the ** of other trace elements is equally important. Under the condition of applying sufficient basal fertilizer, phosphorus, potassium and magnesium boron fertilizers should be applied before the flower bud differentiation stage and the flowering and fruiting stage to promote the transformation of multi-flower, multi-fruit and fruit color.

5. Strengthen the light and avoid planting tomatoes in a cool place. During the growth process, try to provide light conditions for tomatoes, improve the degree of light, and improve the efficiency of light energy conversion.

6. Use foliar fertilizer correctly, avoid excessive use of hormone growth regulators, and avoid spraying foliar fertilizer when there is a problem; If you find that the tomatoes are overgrown, you can spray 50% chloroquine 1000 times to inhibit the growth of the tomatoes, or spray other growth inhibitors.

7. Avoid pollution, avoid planting tomatoes on the ground polluted by industry, avoid watering tomatoes with polluted water sources, and avoid planting tomatoes around strong radiation sources and air pollution sources; During soaking and disinfection, avoid excessive temperature or soaking for too long.

First, the planting density is high, the ventilation and light transmission are poor, and the leaves are thin and yellow. In order to win honors, this overgrowth is often seen in greenhouses in winter and in constant rainy weather in spring and summer. The prevention method is simple.

As much as possible, by controlling planting density, pruning branches, etc., to improve ventilation and light transmission, more light will naturally alleviate overgrowth.

Control fertilizer and water. There is enough fertilizer and water at the bottom. In general, do not fertilize and water before flowering and fruit set.

Timely spraying of vegetable and fruit in the pre-flowering, young fruit stage and expansion stage can activate the positive energy of plant ecological growth, broaden the plant channel, improve the intensity of plant water and fertilizer absorption, and improve fruit yield and quality.

It is necessary to control the water and fertilizer, so as to better ensure the growth of plants, and we must pay attention to the selection of varieties and the surrounding environment.

Growing tomatoes often encounters various problems, but the biggest headache for growers is that tomatoes do not grow and the fruit is not large. In this way, there is a direct impact on economic value and economic benefits. And apart from the lack of nutrients, it is difficult to think of other reasons, and usually there is nothing to do after fertilization.

In fact, the reason why tomatoes don't grow for a sake or a lot is not just a nutritional deficiency. Let's share with you what causes tomatoes not to grow.

Loam soil consolidation is best, sandy loam soil is of medium level, but sand fertilizer and water are very easy to drain out, which will eventually cause a lack of soil fertility. Therefore, loamy soil and sandy loam can be used for planting, and there is no need to use sandy soil, if there are no more land resources, the soil can be improved, and humus and loam can be added. Insufficient soil fertility can lead to non-growth.

The fruit of tomatoes is mainly used in the period of low base fertilizer and high potassium fertilizer, and the carotene contained in the fruit is dissolved in the case of medicine, but it is not dissolved, which is due to the application of too much base fertilizer, so that the carotene is not dissolved, and the form of lycopene cannot be formed. Low potassium can also be harmful, plant photosynthesis will be reduced, damage color, metabolism is relatively slow, and harm off the bag. In that case, it is best to use a water-soluble fertilizer with high potassium, and the potassium fertilizer requirement should be twice that of the base fertilizer.

Extra-root fertilization can also be applied and potassium dihydrogen phosphate can be sprayed to fill in the zinc element.

If it is planted in a greenhouse out of season in winter, because the outside temperature is too low, it will affect the temperature of the internal structure. It can not be often ventilated and breathable, the air is not good, and the sun is not obvious in winter. The fruit is not easy to grow after conclusion, and the growth is stunted.

For this matter, it is best to maintain above 25 degrees Celsius during the day and 15 degrees Celsius at night, and electricity must be used to increase the temperature. Tianjing moderately opens the skylight for ventilation.

It may be that the growth of nutrients and the growth of the reproductive system are unbalanced, for example, in the case of the conclusion, but the branches are vigorous and too abundant, so too many nutrients are consumed, and the nutrition of the conclusion is insufficient, and the market competition but the branches will cause the fruit to be not large. In such a thing, it is necessary to pluck the top of the main vine, thin the branches, and prune some weak branches, branches that do not bear fruit. That kind of growth may be much better, and the conclusion is too much, it can be thinned out moderately.

It may be that the soil is too dry, or it may be malnourished, it may be that boron is missing, or it may be that the concentration of pesticides is too high, which seriously affects the growth of plants.

It may be that the fertilizer needed for tomato growth is insufficient, or it may be that the environment in which the tomato grows limits the size of the fruit.

It is very likely that the fertility of the soil is not enough, or it may be that the cultivation method is wrong, or the temperature outside is not appropriate, and sometimes the temperature is too high or too low will lead to such results.

In both cases, it is not clear which answerer is not clear, so the next time you ask a similar question, try to upload it**, so that it is easy to analyze and answer. The most taboo thing about balcony tomato planting is the long man, which is the main reason why the tomatoes do not bloom and do not bear fruit. Balcony planting, due to the light conditions can not meet the requirements of indoor planting, coupled with the fact that the seedlings are often raised earlier, the water source is sufficient, if the owner is too diligent The nutritional value of tomatoes is very high, and individuals have also planted small tomatoes on the balcony in the past two years, and watched the tomato seedlings grow up, bear fruit, mature, and enjoy their own planting results, and feel that the tomato taste will be different, haha.

Actually, when the tomatoes were planted in the first year.

<> tomatoes are male and female flowers, and tomatoes will never bloom on their own if they are not pollinated during the flowering period. A tomato flower, which has both pistils and stamens, is a self-pollinating plant that needs to be artificially pollinated indoors. Long.

However, it is important to note that tomatoes do not like light for as long as possible. If you have a good floor, the balcony is not covered, and the tomato receives too long a sunshine that exceeds the light saturation point, there will be a problem of only flowering but not fruiting. If the balcony is sheltered, it will also come out.

The problem of not bearing tomatoes. That is to say, after transplanting, the tomato is caused by excessive watering and fertilization in the early stage of growth, or insufficient light in the place where it is placed. For tomatoes to have high yields, fertilizer is particularly important, and the soil bottom fertilizer for growing tomatoes should be lowered.

I think this point cannot be ignored, the bottom fertilizer must be sufficient, and it is not good if the flower pot is small. Long basins or large round basins are fine. The distance between the leaves grows very large, the branches grow very weakly, and the light sees the leaves and the light sees that they are growing, it just doesn't bloom, so we must remember that we want to raise it well.

There are several reasons why the tomatoes planted on the balcony are leafy and only bloom but do not bear fruit. Probably the biggest problem is its luxuriation. Because only a long strut will absorb too much of its nutrients, you need to prune it and leave only a few trunks.

Here's my family's tomatoes.
