Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and more specifically to a greenhouse tomato seedling raising device. Background Art

[0002] Tomato, also known as tomato and foreign tomato, has sticky glandular hairs all over the body and a strong smell. The stem is easy to fall over. The leaves are pinnate or deeply pinnate. The leaflets are extremely irregular, of varying sizes, ovate or rectangular, with irregular serrations or lobes on the edges. Tomatoes are grown all over the country, and the planting area is large. The appropriate sowing period is determined based on comprehensive consideration of factors such as the planting season, climatic conditions, cultivation methods, and seedling facilities. A large amount of planting area requires timely and effective seedling cultivation methods for large-scale tomato planting.

[0003] The current greenhouse tomato seedling raising device, such as the "A seedling raising device for greenhouse tomato planting" proposed with patent number ZL202021500361.X, has a fixed partition fixed in the cultivation box, a support frame is fixed symmetrically up and down in the cultivation box, a bracket is fixed at the bottom of the support frame, a water accumulation frame is inserted in the bracket, and a ventilation mechanism is arranged on the side panel of the cultivation box on the upper side of the support frame, and a No. 1 extension pipe is fixed to the water outlet end of the outlet pipe, and a No. 2 extension pipe is embedded and fixed on one side of the outlet pipe. The other ends of the No. 1 extension pipe and the No. 2 extension pipe respectively pass through the side walls of the cultivation box and are arranged on the upper side of the support frame, and the other ends of the No. 1 extension pipe and the No. 2 extension pipe are both provided with a spraying mechanism; by placing the seedling tray in the seedling rack, a good cultivation environment is provided for the seedling tray, the cultivation quality is improved, thereby improving the planting efficiency of farmers.

[0004] The existing greenhouse tomato seedling raising device places the seedling tray directly on the seedling raising frame. Although it can set up the seedling tray and facilitate cultivation, in actual use, when transplanting is needed, the seedling tray needs to be taken out of the seedling raising frame and moved. The tomatoes or plants at the edge of the seedling tray tend to extend to the outside of the seedling tray as they continue to grow. When the seedling tray is taken out of the seedling raising frame, it is easy to accidentally touch the plants, causing them to break and affecting the seedling raising effect. Transplanting is inconvenient. Therefore, there is an urgent need to improve the technology of the greenhouse tomato seedling raising device structure to improve this equipment.
