Technical Field

[0001] The utility model belongs to the technical field of modern agriculture, and in particular relates to a modern agricultural seedling raising device which is easy to operate. Background Art

[0002] Modern agriculture refers to building agriculture on the basis of modern science, equipping agriculture with modern science and technology and modern industry, and creating a high-yield, high-quality, and low-consumption agricultural production system. In the process of modern agricultural development, the cultivation of seedlings of agricultural products is a common item. When cultivating seedlings, in order to improve the survival rate of seedlings, it is necessary to use seedling raising devices.

[0003] In the Chinese utility model patent with publication number CN213755953U, a modern agricultural seedling raising device which is easy to operate is disclosed. By pulling out and inserting the locking rod into the inside of the pull-out plate, the pull-out plate is easy to install and remove, which shortens the installation and removal time of the pull-out plate, thereby improving the work efficiency of the staff. By controlling the hair dryer to blow hot air and cold air into the seedling box and adjusting the amount of air blown by the hair dryer, different environments in the seedling box can be adjusted according to different seedlings, thereby ensuring the seedling quality of the device.

[0004] However, in the process of raising seedlings, it is also extremely important to allow the seedlings to receive sufficient light. However, the above-mentioned seedling raising device uses a cabinet device for raising seedlings, and the multi-layer seedling raising trays are placed in the same vertical position, with a large overlap area, which is not convenient for the seedlings to fully receive sunlight. In addition, the installation of the seedling raising trays is too cumbersome and has the defect of being inconvenient to operate. Therefore, it is urgent to improve the existing modern agricultural seedling raising device and provide a modern agricultural seedling raising device that is convenient for seedlings to fully supplement light and easy to operate.
