Where is the origin of cherry tomatoes? Introduction to the distribution of main domestic producing areas
Cherry tomatoes are also known as small tomatoes, cherry tomatoes, cherry tomatoes, small persimmons, etc. The official Chinese name is cherry tomato, which is an annual herbaceous plant of the Solanaceae family, Solanum genus. It has the effects of promoting fluid production and quenching thirst, strengthening the stomach and promoting digestion, clearing heat and detoxifying, cooling blood and calming the liver, nourishing blood and supporting vitality, and increasing appetite. Now let us take a look at where cherry tomatoes originate!
Where is the origin of cherry tomatoes?
Cherry tomato is one of the members of the tomato family. Its place of origin is the Andes region of the Americas, and there are still large distributions of wild species in Peru, Ecuador, Bolivia, and other places. The Solanum genus is divided into two complex population groups, common tomato and Peruvian tomato. Common tomato is the cultivated species, and Peruvian tomato is the wild species. Cherry tomato is the ancestor of today's cultivated tomatoes. The producing areas of cherry tomatoes in China are mainly in Hainan, Guangdong, Fujian, and other places, and there is a very large sales volume in northern cities.
The producing area environment of cherry tomatoes
The suitable temperature for the growth and development of cherry tomatoes is 20-28°C. The seed germination stage requires a temperature of 25-30°C, and germination is difficult below 14°C. During the seedling stage, the daytime temperature is 20-25°C, and the nighttime temperature is 10-15°C. During the flowering and fruit-setting stage, it is 20-28°C during the day and 15-20°C at night. Below 15°C, growth and development are slow. When the temperature is above 35°C, plant growth is slow and it can also cause flower and fruit drop. During the fruit development stage, it is generally 24-28°C during the day and 16-20°C at night, and the diurnal temperature difference is kept at 8-10°C. It has strong adaptability to soil, and loam or sandy loam with convenient drainage and irrigation and loose, fertile soil is preferable.
