Tomato is a warm-loving vegetable, which has semi-drought-tolerant physiological characteristics, such as being warm and afraid of cold, light and heat, air dryness and humidity, and water and waterlogging. According to the local natural cultivation environment, we should properly adjust the living conditions such as temperature, humidity, moisture, light, nutrition supply, etc., which are suitable for vegetable growth, and also prevent and control various possible pests and diseases.

Temperature requirements of tomatoes: tomatoes have different temperature requirements at different growth stages. The optimum temperature for seed germination is 25-30 degrees Celsius, the lowest germination temperature is 1 1 degrees Celsius, and the highest is 35 degrees Celsius. It is suitable for 20-25℃ in the daytime and 15-20℃ at night in the seedling stage, and 25-30℃ in the daytime and 13- 17℃ at night in the fruiting stage. It is not conducive to flowering and fruit setting if it is lower than 15℃ and higher than 35℃.

Requirements of tomatoes on soil: tomatoes are not strict on soil, and they can be planted in loam with thick soil layer and good drainage and strong soil permeability, and in alkaline soil with improved sandy loam.

Tomato's requirements for light: tomatoes have different requirements for light at different growth stages. They don't need light at germination stage, but they need enough light at seedling stage to develop well. Insufficient light will affect flower bud differentiation and pollination. In the fruit-bearing period, there are many fruits set with sufficient light, and the fruit expands quickly. Insufficient light will affect the yield, and too strong and lasting light will cause sunburn to the fruit.

Requirements of tomatoes for water: tomatoes have developed roots, strong water absorption capacity and strong evaporation water from leaves, which are drought-tolerant crops, that is, they need a lot of water for drought tolerance, and they grow fast in seedling stage, so the soil should not be too wet. Therefore, watering should be controlled, and frequent watering is needed during flowering and fruiting period. Generally guarantee 10 days or so.
