Tomato is a thermophilic vegetable. Under normal conditions, the optimum temperature for assimilation is 20-25℃, and the optimum soil temperature for root growth is 20-22℃. The light saturation point is 70000lx, and the suitable light intensity is 30000-50000lx. It is also a short-day plant. Tomatoes are water-loving, generally 60-80% soil humidity and 45-50% air humidity.

Tomatoes are less demanding of soil conditions and grow well on rich loam soil with deep, well-drained, organic-rich soil layers. The pH of soil is 6-7.
