Tomato grow

Tomato, scientific name Lycopersicon esculentum, also known as tomato or persimmon, is an annual or perennial herbaceous plant of the Solanaceae family. Tomatoes are native to Central and South America and are now widely grown around the world. The fruits are round, oval or peach-shaped and come in various colors, including red, yellow, green, orange and pink. Tomato pulp is sweet and sour and can be eaten raw or cooked. It is a favorite vegetable and fruit for many people.
Tomatoes are rich in nutritional value and contain a variety of vitamins and minerals, such as vitamin C, vitamin A, vitamin K, B vitamins, calcium, potassium, phosphorus, magnesium, etc. Additionally, tomatoes contain antioxidants such as lycopene and beta-carotene, which help protect the body from free radical damage.
Tomatoes can be eaten in a variety of ways. They can be eaten raw, stir-fried, made into soups, and made into sauces and sauces. In addition, tomatoes can also be processed into tomato juice,

When to start planting tomatoes and steps to grow them

Tomato sowing time varies by region and growing method. Generally speaking, spring and autumn are common seasons for sowing tomatoes. With greenhouse or indoor growing, sowing time is more flexible because temperature and light can be controlled. You can sow tomatoes any time of year, in a greenhouse or indoors.
1. Prepare the greenhouse: Make sure the greenhouse temperature is appropriate and the ventilation is good. If the greenhouse temperature is too low, insulation measures can be taken, such as adding insulation or heating.

2. Sowing: Purchase tomato seeds according to planting time and variety characteristics. Sow the seeds in fertile, well-drained soil, sowing an appropriate amount per seedbed. Pay attention to keeping the soil moist to promote seed germination.

3. Seedling cultivation: When the tomato seedlings grow to a certain height (usually 8-10 cm), they can be transplanted to a seedbed or flower pot in the greenhouse. Pay attention to keeping the soil moist to promote root growth.

4. Scaffolding: As the tomato seedlings continue to grow, they need to be erected to allow the tomato vines to climb. You can use materials such as bamboo poles, steel wire, or nylon rope to build the stand.

5. Plant adjustment: When the tomato vines grow to a certain length, the plants need to be adjusted so that they grow along the bracket. Plants can be adjusted using methods such as tying or wrapping.

6. Water and fertilize: Water and fertilize properly according to the needs of tomato plants. Avoid overwatering to prevent root rot. When fertilizing, you can use organic fertilizers, chemical fertilizers or liquid fertilizers.

7. Pruning and topping: In order to promote the growth of tomato fruits, pruning and topping can be used. Pruning refers to trimming off excess branches, and topping refers to removing the growing points at the top of the plant.

8. Pest and disease control: Growing tomatoes in a greenhouse may require attention to pest and disease control. Methods such as biological control, physical control or chemical control can be used.

9. Harvesting: When the tomato fruits are ripe, they can be harvested in time. When harvesting, be careful not to damage the plants and other fruits.

What should you pay attention to when growing tomatoes in a greenhouse?

1. Temperature control: The suitable temperature range for tomato growth is 20-30°C during the day and 15-20°C at night. In the greenhouse, insulation measures such as insulation curtains, heating equipment, etc. can be used to keep the temperature stable. At the same time, avoid temperatures that are too high or too low to avoid affecting growth.

2. Light adjustment: Tomatoes need sufficient light. In the greenhouse, artificial light can be supplemented by adjusting the shading net and using fill lights. Make sure the lighting time reaches 8-10 hours a day.

3. Water management: Tomatoes need sufficient water to grow, but excessive watering may cause root diseases and fruit cracking. In the greenhouse, use drip irrigation or sprinkler irrigation to keep the soil moist. Also, avoid standing water.

4. Fertilizer: Tomatoes need an appropriate amount of fertilizer to grow. In the greenhouse, it is recommended to use organic fertilizers, water-soluble fertilizers or liquid fertilizers. Follow the instructions on the packaging and do not over-fertilize.

5. Plant adjustment: By adjusting the plants, bundling vines, and removing excess branches, leaves and flowers, the plants can be kept ventilated and light-transparent to promote fruit growth.

6. Pest and disease control: Tomatoes grown in greenhouses may be attacked by pests and diseases. In greenhouses, biological control, physical control or chemical control methods can be used. Pay attention to choosing environmentally friendly and low-toxic pesticides to reduce the impact on the environment

tomato grow light

Tomatoes’ need for red and blue light during growth is particularly critical.

Red light: Tomatoes absorb red light mainly for photosynthesis. Red light can promote the photosynthesis efficiency of tomato leaves and increase the growth rate and flowering results of the plants. The wavelength range of red light is generally 610-720 nanometers.
Blue light: Blue light is also important for the growth and development of tomatoes, especially during the flowering and fruiting stage. Blue light can promote tomato flower bud differentiation and improve fruit setting rate and fruit quality. The wavelength range of blue light is generally 400-520 nanometers.
Therefore, when growing tomatoes, supplementing red light and blue light will have a beneficial effect on their growth. In actual production, tomatoes’ needs for red and blue light can be met by using artificial light sources with specific wavelength ranges, such as LED plant growth lights.
