How to prevent tomato fruit from cracking

Tomato (Tomato) alias tomato, persimmon, the ancient name of June persimmon, good news three yuan. In Peru and Mexico, it was originally called "wolf peach". The fruit is rich in nutrition and has special flavor. It can be eaten raw, cooked and processed into ketchup, juice or whole fruit cans. Tomato is one of the most widely cultivated fruits and vegetables in the world. Tomato is a temperature-loving and light-loving vegetable, which is not strict on soil conditions, but in order to obtain high yield and promote good root development, fertile loam with deep soil layer, good drainage and rich organic matter should be selected. Native to South America, it is widely cultivated in the north and south of China.

Medicinal value of Tomato

Tomato has the effects of hemostasis, antihypertensive, diuresis, invigorating stomach and digestion, promoting body mass and relieving thirst, clearing heat and detoxification, cooling blood and calming liver. Due to the appropriate proportion of vitamin An and vitamin C in tomatoes, eating regularly can enhance the function of small blood vessels and prevent vascular aging. The flavonoids in tomato not only reduce the permeability of capillaries and prevent their rupture, but also have the special effect of preventing vascular hardening, which can prevent diseases such as cervical cancer, bladder cancer and pancreatic cancer; in addition, it can also beauty and cure aphtha (can contain some tomato juice, make it contact with the sore surface, several minutes at a time, several times a day, the effect is significant).

Edible value of Tomato

According to the research and determination of nutritionists: 50 grams of fresh tomatoes per person per day can meet the needs of the human body for several vitamins and minerals. Tomato contains "tomato", which can inhibit bacteria; contains malic acid, citric acid and sugars. Tomatoes are rich in carotene, vitamin C, vitamin B and vitamin B2 and calcium, phosphorus, potassium, magnesium, iron, zinc, copper and iodine, as well as proteins, sugars, organic acids and cellulose. Tomatoes are rich in antioxidants. Antioxidants can prevent the damage of free radicals to the skin and have obvious cosmetic and anti-wrinkle effect. Tomatoes are rich in carotene, vitamin C and B vitamins.

How to prevent tomato fruit from cracking?

Tomato fruit cracking disease is a physiological disease, which is easy to occur in the color conversion period of the fruit. According to the location and shape of the fruit, it can be divided into three types: one is radial crack, which is radial in the center of the pedicel, the other is annular crack, which takes the pedicel as the center and shows annular lobes, and the third is strip-shaped cleavage, that is, irregular strip-shaped fissures at the top of the fruit. After the occurrence of fruit cracking, the fruit quality decreased, and the bacteria were easy to invade and rot.

The cause of tomato fruit cracking:

First, it is caused by deformed flowers.

Second, due to the strong light exposure in the later stage of fruit development or color conversion period, high temperature and drought, especially irrigation after a long drought, it is easy to cause the peel growth to be out of sync with the expansion rate of pulp tissue, and the swelling pressure increases and fruit cracking occurs.

Third, the improper use of plant growth regulators, the concentration is too high, water and fertilizer can not keep up, resulting in physiological imbalance and fruit cracking.

Fourth, the heart is picked too early, resulting in concentrated supply of nutrients to the fruit, resulting in fruit cracking.

Prevention and control methods of tomato fruit cracking:

1. Select crack-resistant varieties, generally choose small and medium-sized varieties with thick pericarp.

2. The temperature in the seedling stage, especially in the flower bud differentiation stage, should not be too high or too low. The temperature should be kept at about 24 ℃ in the daytime, 15-17 ℃ at night, and not lower than 8 ℃ at night for a long time.

3. Prevent strong light from shining directly on the pericarp. In the late autumn and early spring cultivation, do not prematurely remove the bottom leaves, can play a shading effect for the fruit.

4. Prevent the soil from being too dry or too wet, and keep the soil relative humidity at about 80%.

5. Increase the application of organic fertilizer and good quality biological fertilizer to improve the soil structure and provide a good environment for root growth. Foliar should often supplement calcium, boron and other trace elements.

6. in the correct use of plant growth regulators, when using hormone spray, the concentration is not easy to be too high, and the concentration should be reasonably determined according to the variety and temperature.

7. Pruning and branching should be moderate, keep the plant with luxuriant leaves, strengthen the transpiration of excess water in the plant, and avoid fruit cracking caused by concentrated supply of nutrients.
