In China, the production areas of cherry tomato are mainly in Hainan, Guangdong, Fujian and other places, and there is a very large sales volume in northern cities.
The production environment of cherry tomatoes
The suitable temperature for the growth and development of cherry tomato 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, the daytime temperature is 20-28°C and the nighttime temperature is 15-20°C. 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, the daytime temperature is generally 24-28°C and the nighttime temperature is 16-20°C, with the temperature difference between day and night 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 texture is preferable.
