Introduction to the growth process of tomatoes, relatively short!

Photographic germination period of tomato growth cycle: from sowing to the appearance of the first real leaf (broken heart) At room temperature, this period is 7 ~ 9 days;

Seedling stage: refers to the period from the appearance of the first true leaf to the appearance of the first inflorescence. The suitable daytime temperature is 25 ~ 28℃, and the nighttime temperature is 13 ~ 17℃. The ground temperature in this period has great influence on seedling growth, and the suitable ground temperature should be kept at 22 ~ 23℃. The first flowering and fruit-setting period refers to the period from the first inflorescence to fruit-setting. This stage is the turning point of tomato from vegetative growth to reproductive growth and vegetative growth, which is directly related to the formation and yield of product organs;

Fruiting period: from the first inflorescence to the end of harvesting (seedling pulling). In this period, fruits and seedlings grow at the same time, so it is a key task to solve the contradiction between vegetative growth and reproductive growth.
