Tomato fruit cracks, what is the cause?

Suitable for Solanaceae crops, melons and fruit crops, cracks, cracks and even cracks often appear on the surface of the fruit before the fruit expansion or ripening stage, and these problems are generally called fruit cracking. Fruit cracking not only reduces the quality of the fruit, but also makes it susceptible to infection by germs, causing the fruit to rot. <>

Many farmers who do not have a good grasp of agricultural knowledge often one-sidedly believe that the cracks and cracks of fruits are caused by calcium deficiency, and blind calcium supplementation cannot effectively prevent and control cracks or cracks of fruits. In fact, even though a crop calcium deficiency can easily lead to fruit cracking, such as cracking, there are many reasons why a fruit can crack. For example, poor light, unbalanced fertilizer nutrients, drastic changes in soil temperature, uncomfortable temperature conditions, improper use of hormones, if the cause of fruit cracking is not correctly judged, or the phenomenon of fruit cracking or cracking is not caused by calcium deficiency, even if more calcium fertilizer is added blindly to the crop, the problem of fruit cracking cannot be solved.

From the location and shape of cracks or cracks on the surface of tomato fruits, tomato fruit dehiscence can be divided into three types as a whole: radioactive fruit dehiscence, annular fruit dehiscence, and strip fruit dehiscence. <>

Among them, the cracks or cracks that radiate from the fruit base to the fruit shoulder are called radioactive cracks, which mainly occur in the green ripening stage of tomato fruits. The cracks or fissures that appear in rings or concentric circles around the base of the fruit are called annular fissures, and this type of fissure mainly occurs before the tomato fruit matures; The cracked fruit or cracked fruit at the top of the fruit is called striped cracked fruit, which may occur during the expansion of the fruit to maturity, because the cracked fruit or cracked fruit phenomenon is irregular, and the pattern or direction of the cracked fruit is uncertain in both horizontal and vertical directions, so the striped cracked fruit of tomato is often called mixed cracked fruit. There are many reasons for tomato fruit splitting, including variety physiological reasons, uncomfortable growing environment, improper field management, pests and diseases, etc. In order to effectively prevent and control the phenomenon of tomato fruit cracking, it is necessary to accurately determine the specific causes of tomato fruit cracking in our own land, and then take targeted measures to prevent and alleviate the symptoms.

Tomatoes are cracked because of a lack of nutrients, and this problem must not be underestimated!

When the tomato is young, the soil is relatively dry, but in the later stage, it is suddenly watered with large water, which can easily cause the tomato to quickly absorb water and swell and cause cracking. The plant is too heavy and the fruit is watered suddenly after being exposed to strong sunlight, which is also prone to fruit cracking.

This is probably due to the large temperature difference between day and night, which reduces the toughness of the tomato peel, so the tomato fruit will crack.

The temperature difference between day and night is too large or sometimes the weather is cloudy and changeable, resulting in drastic changes in the temperature in the shed, so that the growth rate of the pulp is not synchronized with the growth rate of the peel, resulting in fruit cracking. In addition, under the condition of high temperature or strong light, the temperature of the fruit surface increases, which can easily lead to the increase of pressure on epidermal cells, and the toughness and hardness of the peel decrease, and at this time, the content of soluble solids in the fruit is high, the fruit growth rate is fast and the toughness of the peel is reduced, resulting in fruit cracking. In addition, the sudden loss of large amounts of water from the fruit surface is also an important factor in inducing fruit cracking.

Tomatoes with patterns on the fruit and cracks.

Hello, dear, radial cracks are mainly related to high temperature, strong light exposure, drought, especially sudden watering after a long drought. Concentric circle fissures and fruit side fissures mostly occur when there are water droplets on the fruit surface. In the above-mentioned poor conditions, the cork layer produced by the fruit surface is suddenly absorbed, resulting in cracked wild dan.

Sudden watering after a long period of drying will cause the flesh to not expand synchronously with the aged peel, causing the peel to crack. What is the ** of the striated fruit of the tomato. Causes:

Radial cracks are mainly related to high temperature, strong light exposure, drought, especially sudden watering after a long drought. Concentric circle fissures and fruit side fissures mostly occur when there are water droplets on the fruit surface. In the aforementioned undesirable conditions, the cork layer produced on the fruit surface is suddenly absorbed and cracked.

Sudden watering after a long time will make the flesh and the peel that has aged the state not expand synchronously, causing the peel to crack.

1. Characteristics of the variety. Generally speaking, varieties with thicker peels and resistant to transportation have slightly worse annular cracks; Varieties with thin skins are more severe. Therefore, it is very important to select varieties, and it is necessary to select resistant varieties with thick peel and storage and transportation.

2. It is suitable for the wind to be released without branches. There is a large temperature difference between day and night in the shed. The fruit surface and leaves are prone to condensation.

If there is a lot of dew on the fruit surface, the water on the fruit surface will evaporate rapidly, and it is easy to appear that the wind sweeps the fruit as the vegetable farmer said, which is manifested as the fruit surface cracking. Therefore, it is important to let the wind out at the right time.

3. Unbalanced fertilizer and water. 7-20 days after the tomato is dotted is the period of rapid fruit expansion, and sufficient water and fertilizer** are required to improve the yield. If there is uneven drought and flood, the fruit is prone to ring cracking.

Therefore, after the tomatoes enter the fruit expansion period, according to the soil moisture of the shed, top dressing and watering in time are carried out, and the chaos is guaranteed to be too dry and wet, and there is no water and fertilizer.

4. Picking fruit too late. There is a period of swelling in the post-ripening period of the fruit, and if the fruit is not picked in time, it is easy to have small longitudinal cracks; If the fruit is picked too late, it is often said that it is too ripe", and a long crack will appear extending downward from the fruit stalk. Therefore, it is necessary to remove the fruit in time when it reaches commerciality.

One of the main factors in tomato fruit cracking is the lack of mineral elements; Tomatoes need to apply a large amount of potassium fertilizer during the growing season, and the demand for nitrogen fertilizer is reduced, and if a large amount of nitrogen fertilizer is applied at this time and the amount of potassium fertilizer is ignored, it will cause potassium deficiency in fruits, and will also affect the absorption of calcium and boron by crops.

Or in the late stage of fruit development or veraison period, it encounters strong light irradiation, high temperature and drought, especially irrigation after a long period of drought, which can easily lead to the growth of the peel and the expansion rate of the pulp tissue are not synchronized, and the expansion pressure increases and the fruit cracks.

Tomatoes are cracked because of the poor selection of varieties, as well as not using the right temperature. The cracked fruit of tomatoes is intrinsically related to the quality of tomatoes, and it is easy to crack if there is no good quality. When choosing seeds, you must choose carefully, and if you have no experience, you can choose to find your own parents.

The temperature must be too low, otherwise the tomatoes will crack. If you see a tomato with deformed flowers, it means that it will either fall or it will grow bad fruit. The plants should not be exposed to bright light, so that there is not as much water.

It is best to put it in a place with a suitable temperature, so that the seedlings will grow better and better. <>

Tomatoes are not drought tolerant and must be well hydrated. If there is a lack of moisture, tomatoes will crack their fruits. In case of rainy weather, it should not be ignored, otherwise the flesh will be too swollen and cracked.

If the rain is too big, don't think it's the best way to grow tomatoes. It is only the right amount of water that needs to be able to keep the soil well hydrated and have sufficient nutrients. When it rains heavily, you can use a drainage ditch to block it, so that the moisture can still be locked in time.

When you have nothing to do, you should prevent the cracking of tomatoes, and be sure to put organic fertilizer when deep ploughing. Organic fertilizer can improve the structure of the soil and also allow more nutrients in the soil. Only when the roots absorb these nutrients will they continue to grow strongly.

Tomatoes should not contain too much potassium, otherwise they will crack. Only by doing a good job of prevention can the tomatoes grow as long as possible, and they can be sold at a good price. <>

In general, the management of tomatoes is more complicated, and pruning and pruning are carried out at a later stage. Doing this will not happen to the tomatoes, and there will be no cracking. Tomatoes are rich in vitamin C, which is particularly good for the body, and those who want to ** can choose to eat more.

It could be that there is too much fertilization, there is a lack of water, there are pests and diseases in the plants, there is damage to the roots, or it is possible that the land is too dry, and then this can happen.

When the tomatoes are fruiting, the temperature is too high, the water is too little, the nutrients of the soil are relatively low, the soil is rigid, and the quality of the tomato varieties is not good.

The temperature rises suddenly, and the tomato plants are exposed to the sun's rays and have less moisture. It is also possible that the temperature is particularly low at night.

Tomato fruit splitting is a common physiological phenomenon. There are usually three types of fruit cracks: one is radial fruit splitting, this type is centered on the fruit pedicle, extending to the shoulder of the fruit, showing radial deep lobes, starting at the green ripening stage of the fruit, producing fine stripes and cracking near the fruit pedicle, and the crack is obvious 2 to 3 days before veraison; The second type is annular fissure, which is centered on the pedicle and has a shallow annular lobe, which generally appears before the fruit is ripe; The third type is the striped fissure, which is irregularly striped at the top of the flower scar.

The main reason for the cracking of tomato fruits is water imbalance. In the late stage of fruit development or veraison, when the growth of the peel is not synchronized with the expansion rate of the pulp tissue, the expansion pressure of the fruit increases, resulting in the phenomenon of fruit cracking. In particular, showers or torrential rains hinder the physiology of the root system, hinder the absorption and operation of boron, and fruit cracking will occur.

The fruit cracking is also prone to fruit cracking after being exposed to strong sunlight and sudden rain, or after continuous rainy weather, the sky suddenly clears and the peel is excessively dehydrated, which is especially serious in the rainy season. In addition, the fruit splitting of tomato is also very related to the variety, with varieties with thin peel prone to fruit splitting, while varieties with thick peel are less likely to crack fruit. However, tomato cracking has little to do with the size of the fruit, and even small fruit-shaped varieties such as cherry tomatoes can easily crack the fruit.

The main aspects of preventing tomato fruit cracking are as follows:

1) Variety selection.

It is advisable to choose varieties that are resistant to cracking, have lush foliage, and have thicker and tougher peels.

2) Keep the soil moist often.

Mulching or straw mulching is used to maintain a relatively stable soil moisture, and to prevent sudden dryness and wetness, especially when entering the fruit expansion and harvest period, it is necessary to keep the soil moist.

3) Deep furrow and high furrow cultivation were used to increase organic fertilizer to improve soil structure and improve soil water and fertilizer retention capacity.

4) Timely and appropriate pruning and topping to ensure that the plants are luxuriant, strengthen the transpiration of excess water in the plants, and prevent strong light from directly hitting the fruits.

5) Harvest tomatoes in time before heavy rains.

6) On the basis of maintaining a relatively stable soil moisture content, spraying the plant with Bordeaux liquid after the fruit enters the expansion stage has a significant effect on preventing tomato fruit cracking.

In addition, in the case of boron deficiency in the plant, cracking can also occur at the end of the fruit stalk. In terms of prevention, borax should be appropriately increased when ploughing the ground, generally per 667 square meters of kilograms; Once this cracking occurs, borax should be sprayed in a timely manner.

The reasons for the fruit cracking of tomatoes are: first, the temperature at the seedling stage is low, the ovary is not developed normally, and the fruit is cracked after expansion; Second, the concentration of plant life regulators is too high; Third, after rainfall, the root system absorbs a large amount of water or the cork tissue in the skin of the fruit directly absorbs water; Fourth, it is exposed to strong sunlight after rain; fifth, excessive maturity; Sixth, some varieties have larger fruit shapes, thinner peels, poor ability to adapt to the external environment, and are prone to fruit cracking. Measures to prevent fruit splitting:

The first is to select crack-resistant varieties and cultivate strong seedlings; Second, deep ditches and high ridges should be achieved in rainy land and rainy seasons to facilitate timely drainage, timely watering in times of drought, to prevent the soil from being too dry, and to ensure that the soil moisture is balanced. Third, the concentration of plant growth regulators should be appropriate; Fourth, harvest in advance at the right time to reduce the number of cracked fruits.

Tomato fruit cracking disease is a phenomenon in which cracks appear on the surface of the peel when the fruit is nearing ripeness. There are three main types of cracked fruits: radial, ring, and striated. The radial fissures are initially at the green ripening stage of the fruit, and the fine stripes and cracks are produced near the fruit pedicle, and the cracks are obvious 2 to 3 days before veraison, and the cracks are radial, with the fruit pedicle as the center, extending to the shoulder of the fruit, showing radial deep fissures. annular lobed fruit, which is annular shallow lobed around the fruit pedicle, mostly appears when the fruit is nearly ripe; Streaked fissures are irregular strips at the top of the fruit.

Causes of fruit cracking: The main cause of fruit cracking is uneven soil moisture**. The soil is dry for a long time, the peel stretchability is reduced, and the pulp expands rapidly when suddenly watered, which makes the peel crack.

Methods to prevent this from happening: the supply of soil moisture should be even; Protects the fruit from sunburn.

Can you still eat tomato cracked fruit and why does it crack fruit? After reading it, I realized that we were all wrong!

Tomato cracks, i.e., irregular strip-like cracks at the top of the fruit. After the fruit cracking, the quality of the fruit decreases, and the pathogens are easy to invade, resulting in rot. Causes of fruit cracking:

First, the temperature at the seedling stage is low, the ovary is not developed normally, and the fruit cracks are produced after expansion; Second, the concentration of plant life regulators is too high; Third, after rainfall, the root system absorbs a large amount of water or the cork tissue in the skin of the fruit directly absorbs water; Fourth, it is exposed to strong sunlight after rain; fifth, excessive maturity; Sixth, some varieties have larger fruit shapes, thinner peels, poor ability to adapt to the external environment, and are prone to fruit cracking.

Measures to prevent fruit cracking: first, select crack-resistant varieties and cultivate strong seedlings; Second, deep ditches and high ridges should be achieved in rainy land and rainy seasons to facilitate timely drainage, timely watering in times of drought, to prevent the soil from being too dry, and to ensure that the soil moisture is balanced. Third, the concentration of plant growth regulators should be appropriate; Fourth, harvest in advance at the right time to reduce the number of cracked fruits.
