What s the deal with tomatoes that grow out of shape?

There are many reasons for tomato deformity, low temperature in the flower bud differentiation and development period, low temperature drought in the seedling stage, long flower bud differentiation time, improper use, etc., after the uncomfortable stage, the conditions are suitable, it will cause fruit cracking, fruit, of course, some varieties are not adaptable, there will be more, mainly caused by external factors. In addition to variety selection, reduce the dosage, the use of ecological bulking agent, the key is seedling and seedling management, regulate temperature and humidity, and avoid excess nutrition at the seedling stage, that is, the seedling stage to master better soil conditions, can not be too dry and too wet, and low temperature, to maintain its normal growth and flower bud differentiation, humidity and temperature coordination in order to reduce deformed fruits. Spraying Kao 3 at the flower bud differentiation stage can control the crazy growth of branches, and the assimilation induction can promote the transmembrane signal conversion of plant cells, forcing a large amount of nutrients from the top tips to return, and the main nutrients of the main stem can be transferred to the young fruit development system to improve the fruit expansion and vitality.

The main reason is that the nutrition is very unbalanced, and secondly, it is also because the sun's light and moisture are particularly inconsiderate, so such a problem will occur.

Pay attention to the use of pesticides, pay attention to the use of fertilizers, pay attention to watering, pay attention to the condition of the soil, plant scientifically, and pay attention to the situation of the variety.

Causes of deformed tomato flowers and preventive remedies1. Causes of deformed tomato flowersDuring the differentiation period of seedling flower buds, the night temperature was lower than 15 degrees, and it encountered rainy and weak light days. The average temperature is high and high at 25 degrees, the number of flowers decreases, the flowers are small, the anthers are underdeveloped, the empty medicine, the stigma is slender, and the flower buds stop growing and turn yellow; partial application of ammonia fertilizer; or excessive water control, seedlings grow or grow into aging seedlings; Varieties that are not resistant to low temperatures are selected. All of the above factors can easily lead to the formation of deformed flowers in tomatoes.

2. Preventive measures for deformed tomato flowers1. It is necessary to choose varieties that are resistant to low temperature and weak light, have thick fruit skin, small changes in ventricular number, and less deformed fruits.

2. Strengthen the temperature management of seedlings, in order to prevent seedlings from growing, more cooling oak should be adopted, especially the method of reducing night temperature, although it can prevent growth, but there are many deformed flowers. To this end, the method of slightly controlling temperature and more water can be adopted. When the seedlings grow to 2 or 4 leaves, they enter the flower bud differentiation stage, and the temperature of the seedbed is maintained at 24 to 25 degrees during the day, 15 to 17 degrees at night, the temperature difference is 8 to 10 degrees, and the ground temperature is 18 to 22 degrees.

It is maintained until half a month before planting.

3. When the seedling is 15 cm high, start to control the water. If the seedlings are raised in plastic bowls, the bottom water should be poured enough when the seedlings are divided, and the seedlings can also be managed according to the leaf color when the seedlings are 15 cm high. Fertilization should be sufficient for seedbed nitrogen fertilizer, but not too much, please, potassium fertilizer and calcium, boron and other trace elements in an appropriate amount.

Keep it well lit and humid, and avoid being too dry or too wet. After entering the flower bud differentiation stage, when there are symptoms of lack of fertilizer such as light leaf color, thin leaves and thin stems, diluted urea solution and potassium dihydrogen phosphate nutrient solution can be poured. The seedling furrow covering material should be well transmitted, and it is necessary to pay attention to frequent cleaning and dusting, and the grass should be covered early and evening, so that the seedlings receive light for more than 8 hours.

3. Remedies for deformed tomato flowersCombine pruning and pruning, and remove deformed flowers in time.

Tomatoes (tomatoes) are prone to deformed fruits, and the fruits exhibit deformed and strange shapes, such as spire-shaped; The umbilicus is prominent, like an olecranon; polygonal; neoplasia (prominent nodulous protrusions in the umbilicus or proximal pedicle); Half-top shape (the top of the fruit is swollen, and the other half is not swollen or not swollen enough, forming a half of the fruit top). It happens for the following reasons:

1. Low temperature. In the flower bud differentiation and development period, if the low night temperature of 3 4 is encountered for 5 6 consecutive days, it is easy to produce deformed fruits. The 1st and 2nd ears of winter and spring tomatoes are prone to deformed fruits, which are mostly caused by low temperatures.

2. The seedling stage is elongated. If the low temperature or drought lasts for a long time, the seedlings are in the condition of inhibiting growth, the development period of the flower organ is elongated, and it is easy to be corked, and then transferred to suitable conditions, the corked tissue can not adapt to the rapid growth of the tissue, and it is easy to form cracked fruits and scar fruits.

3. Unreasonable fertilization. Too much nitrogen fertilizer will cause the flower buds to be over-differentiated, the number of ventricles will increase, and multi-ventricular malformation fruits will be formed.

4. Improper use of hormones. In order to prevent flower and fruit dropping, 2,4-d or tomato spirit is often used to dip the flowers, if the concentration is too high, repeated dipping of the flowers, or the temperature is too high when dipping the flowers, the soil is dry, etc., it is easy to produce deformed fruits. The unopened flowers are dipped in medicine, and it is easy to produce hollow fruits.

In addition, when the seedlings grow, the use of plant growth regulators with a large concentration or many times to control the seedlings, and then dip in the flowers are also easy to produce deformed fruits.

There are three common deformed fruits for growing tomatoes in greenhouses, and how are hollow fruits produced?

The primary reason for the deformed fruit of tomato is that the tomato encounters low temperature in the seedling stage and flower bud differentiation stage, and secondly, improper use of hormones can sometimes cause deformed fruit, in addition, in the tomato flower bud differentiation stage, if the plant has too much nutrient accumulation, it is easy to make the flower deformed and lead to fruit deformity.

Tomato deformed fruit is one of the common diseases of tomato, and it can be threatened by protected land and open field cultivation. The following is a list of the reasons for the deformed tomato fruit, let's take a look! Causes of tomato deformed fruit (1) Low temperature.

In the stage of flower bud differentiation and development, if the low night temperature of --day is encountered for consecutive days, it is easy to produce deformed fruits. The first panicle fruit of the tomato stubble in early spring is prone to produce deformed fruits, which are mostly caused by low temperature or drought. (2) Long seedling stage.

Low temperature or drought lasts for a long time, seedlings are in inhibited growth conditions, and the development period of flower organs is elongated, and it is easy to be corked. Under suitable conditions, the corked tissue could not adapt to the rapid growth of the tissue, and it was easy to form cracked and scarred fruits. 3. Unreasonable fertilization.

Too much nitrogen fertilizer will cause flower buds to differentiate, increase the number of ventricles, and form multiventricular malformed fruits. 4. Improper use of hormones. Use 2, seedlings or tomato spirit mixed with flowers, if the concentration is too high, or repeated after flowering, or cool with medicants.

Add 2 to the flowers, or tomato spirit mixed with flowers, it is easy to produce deformed fruits. In the absence of flowering, the agent is used. The concentration of growth regulators injected into seedlings is large or the number of times, and then doped in flowers, it is also easy to produce deformed fruits.

The pathogenesis of tomato deformed fruit mainly depends on the quality of flower bud differentiation. In general, 3-6 days after tomato germination, 1 true leaf begins to differentiate, 1-6 days, the first flower begins to differentiate, and 60 days the third flower also begins to differentiate. At this time, the seedlings have grown to 1 true leaf and have budded or flowered.

The above-mentioned process is completed in the seedling stage, when the inflorescence formation at the seedling stage encounters low temperature, sufficient water, and more nitrogen fertilizer, the flower buds are over-differentiated, and the multi-carpel deformed flowers are formed, and the fruit is peach-shaped, tumor-shaped or finger-shaped, etc.; If the seedling age is elongated, the low temperature or drought time is long, the seedling is in a state of inhibition growth, the flower is easy to embolize, and then turn to suitable conditions, the corked tissue can not adapt to the rapid growth of the internal tissue, then the formation of cracked fruit, scar fruit or column exposed fruit: therefore, there are more deformed fruits in the low temperature and rainy years in winter and spring, and a few in late spring or summer and autumn. Prevention of the occurrence of tomato deformed fruits(1) Select varieties that are not easy to produce deformed fruits, and remove them in time after the deformed fruits appear, so as to facilitate the development of normal flowers and fruits.

2) Do a good job in light and temperature control, and cultivate strong seedlings with strong resistance to stress. Advocate the use of light ** rapid seedling; After the seedlings break their hearts, they need sufficient light and timely ventilation. Night temperature and evening temperature are conducive to flower bud differentiation and raise seedlings of about 60 days.

3) Strengthen fertilizer and water management to prevent plant growth. Formula fertilization is used to meet the nutritional status required for plant growth and development, avoid over-fertilization, and prevent differentiation into multicarpels and the formation of ribbon-like flat flowers. (4) Rational use of growth regulators.

Seedlings appear to be inches long. However, on the basis of strengthening ventilation and proper humidity control, spray 85% of the specific length (B9) soluble powder 2000 wind soluble powder 2000 wind power to control the length. It can improve the quality of seedlings without affecting flower bud differentiation.

It may be that the tomato is planted too densely, the moisture of the tomato can't keep up, and the nutrition can't keep up, so it will grow into a deformity. Supplement more nutrients so that you can avoid the growth of deformities.

This is due to a problem with the variety, or a problem with the environment in which it grows, or because it has mutated, or because it has been infected, or because it has been infected.

There is a problem with the light time, and the proper fertilizer is not added, which is why the tomatoes will grow into a deformed shape.

I think it has to do with human causes, temperature reasons, fertilization reasons, soil reasons and air reasons. So when this happens to the plant, it must go to ** in time.

1. The deformity of fruits is often caused by the imbalance of varieties, water and nutrients, such as high soil moisture content at the seedling stage and flowering and fruiting stage, excessive application of nitrogen fertilizer, frequent rain and insufficient sunlight will lead to the deformed development of tomatoes. 2. It may have certain defects in the process of breeding, and it can only be said that the varieties with better stress resistance should be selected as much as possible. As a necessary condition for agricultural planting, when applying base fertilizer, an appropriate amount of farmhouse fertilizer should be put into the appropriate amount of farm fertilizer according to the soil organic matter content and water content, and the nutrient soil should be cultivated first when necessary.
