The tomato grafting seedling raising temperature control device comprises a grafting seedling raising information monitoring module, a temperature adjusting module, a central control module and a seedling raising information monitoring platform, wherein the grafting seedling raising information monitoring module is used for continuously monitoring the temperature of the environment, seedbeds and water required by tomato grafted seedling cultivation and collecting image information of the growth state of the tomato grafted seedlings; the temperature adjusting module is used for increasing and decreasing the temperature of the greenhouse environment, the water temperature for watering the grafted seedlings and the temperature of the seedbed of the grafted seedlings according to the adjusting signal sent by the central control module; the central control module is used for storing and processing the temperature information and the image information sent by the grafting seedling raising information monitoring module; and the seedling raising information monitoring platform is used for visually monitoring the production state of the grafted seedlings and the temperature change information of the growth period. The tomato grafting seedling raising temperature control device can monitor the growth state and the growth temperature of the grafted seedlings continuously, remotely and automatically, and the seedling raising management efficiency of the tomato grafted seedlings is improved.
