Where are the tomatoes from?

Tomatoes originated from South America, and the center of origin is the Andes in South America. There are still a large area of wild species in Peru, Ecuador, Bolivia and other places. At present, tomato is one of the most widely cultivated fruits and vegetables in the world. It is widely planted in all parts of China, and the cultivated area continues to expand.

The producing environment of tomatoes

1. Temperature: tomato is a temperature-loving vegetable. Under normal conditions, the optimum temperature for assimilation is 20-25 ℃, and the optimum soil temperature for root growth is 20-22 ℃. Increasing soil temperature can not only promote root development, but also significantly increase the content of nitrate nitrogen in soil, accelerate growth and development, and increase yield.

2. Light: tomato is a light-loving crop, the light saturation point is 70000lx, and the suitable light intensity is 30000~50000lx. Tomato is a short-day plant, which basically requires short-day sunshine in the process of changing from vegetative growth to reproductive growth, but the requirement is not strict. Some varieties can bud and blossom in advance under short-day sunshine, while most varieties blossom earlier under 11-13 hours of sunshine. Plant growth is robust.

3. Moisture: tomatoes not only need more water, but also need not often a large number of irrigation, generally soil moisture 60% 80%, air humidity 45% 50% is appropriate. The high humidity in the air not only hinders the normal pollination, but also causes serious disease under the condition of high temperature and humidity.

4. Soil: tomatoes do not have strict requirements 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. PH6~7 is suitable for soil acidity and alkalinity, and over-acidic or over-alkaline soil should be improved.

Plant Culture of Tomato

Tomato, which was first grown in Peru and Mexico in South America, is a wild berry that grows in the forest. Because of the delicate and colorful colors, the local people regard it as poisonous fruit, as "the fruit of the fox", called "wolf peach", only for viewing, no one dares to eat it, but treat it as an ornamental plant.

According to records, in the 16th century, a Duke of England named Orodara traveled in South America and liked tomatoes as an ornamental plant, so he brought it back to England as a gift of love to his lover Queen Elizabeth to express his love. Since then, the names of "love fruit" and "lover fruit" have been widely spread. But people plant tomatoes in the manor and give them to their lovers as gifts symbolizing love.

Generation after generation, no one dares to eat tomatoes. In the 17th century, a French painter painted tomatoes many times. Facing such a beautiful, lovely and "poisonous" berry, he could not resist its temptation, so he came up with the idea of tasting it for himself. He risked his life to eat one, feeling sweet, sour and sweet in the sour. However, he was all right when he lay in bed waiting to die, so the news that "tomatoes are non-toxic and edible" quickly spread all over the world.

Since then, hundreds of millions of people have relieved to enjoy the benefits of the death of this "dare to be the first in the world" warrior. In the 18th century, Italian chefs made delicacies of tomatoes, which were colorful and delicious, and the guests were full of praise. The tomato is finally on the table. Since then, tomato won the love of everyone, known as red fruit, golden apple, ruby, love fruit.
