Tomatoes are generally annual herbaceous plants with deep roots, well-developed root systems, and deep and wide distribution. Their main root groups are distributed within a 30-60 cm plow layer, reaching a maximum depth of 1.5 meters. The root distribution can reach 60-130 cm in diameter laterally. This is the theoretical basis for the production of "deep-planted tomatoes." Tomatoes have the biological characteristics of thermophilic, hi-light, frost-resistance, heat-resistance, fertilizer-resistance and semi-drought tolerance. When the content of carbon dioxide in the air is normal, the optimum temperature for photosynthesis is 20--25°C, and the temperature is reduced to The plants stopped growing at 10°C, and the lethal temperature of tomatoes was generally -1 to -2°C. If the temperature rises to 30°C, photosynthesis will also be significantly reduced, and when it rises above 35°C, it will stop growing. The high temperature also disturbs and destroys reproductive growth, especially in the meiosis and infertility stages of flower bud development. Suitable for cultivation in his deep, well-drained, organic-rich fertile soil. Tomatoes have more diseases and must be rotated with vegetables other than solanaceous vegetables for a period of 3 to 5 years.
