Embodiment Construction
[0017] The structure of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] In specific implementation, such as figure 1 Shown: a tobacco floating seedling raising and hardening device, including a nutrient solution pool 1 and a seedling raising tray 2, and also includes an air bag 3 located in the nutrient solution pool 1, above the air bag 3 supports the seedling raising tray 2, and the air bag 3 is inflated When the seedling raising tray 2 can be pushed away from the liquid surface 4, the seedling raising tray 2 can be made to fall back into the liquid surface 4 when the air bag 3 deflates. During specific implementation, the airbag 3 is an annular airbag and is supported and connected to the frame of the seedling raising tray 2 . The air bag 3 is connected with the air pump 6 through the air intake pipe 5 , and the air intake switch valve 7 is arranged in the air intake pipe 2 . ...

The invention discloses a tobacco floating seedling raising and training device, which comprises a nutrient solution pond and a seedling raising tray. The tobacco floating seedling raising and training device is characterized in that the device additionally comprises air bags which are arranged in the nutrient solution pond, the seedling raising tray is supported above the air bags, the air bags can jack the seedling raising tray away from the surface of nutrient solution when the air bags are inflated and the seedling raising tray can fall back into the surface of the nutrient solution when the air bags are deflated. Since seedling training is realized by inflating and deflating the air bags and an automatic control system is further arranged to conduct automatic control, the tobacco floating seedling raising and training device disclosed by the invention has the characteristics that the device is convenient, rapid, time-saving and labor-saving, the seedling training effect is improved, the stress resistance of the trained seedlings is improved after the seedlings are permanently planted, the seedlings can survive rapidly and can tiller early and the survival rate of the planted seedlings is high.
Description
technical field [0001] The invention relates to a greenhouse for growing tobacco seedlings, in particular to a tobacco floating seedling raising and hardening device. Background technique [0002] Tobacco is an annual herb belonging to the family Solanaceae. When cultivating tobacco, the seedling stage needs to go through seedling cultivation, and after the tobacco seedlings grow into seedlings, they are transplanted into the soil. For improving the quality of tobacco, the cultivation of tobacco seedlings is a more important key. [0003] Among the existing tobacco seedling raising methods, there is a floating seedling raising method, that is, a nutrient solution pool is used, and the seedling raising tray is floated in the nutrient solution pool, sowing and raising seedlings are carried out on the seedling raising tray, and transplanted to the land after the tobacco seedlings grow. middle. The method for raising seedlings by floating is easy to implement, the labor inten...
