[0001] The utility model relates to the field of tobacco cultivation, in particular to a grid-type tobacco seedling growth device for preventing tobacco root and stem diseases. Background Art

[0002] With the increasing application of chemical fertilizers, the nutrient balance of cultivated soil is serious. In addition, it is difficult to achieve crop rotation and fallow in my country's flue-cured tobacco, resulting in soil compaction and poor permeability. The composition of tobacco-growing soil is seriously damaged, and soil-borne diseases are rampant. The antiviral ability of the roots and stems of each tobacco seedling is different, which will cause the growth of each tobacco seedling to be different. Some tobacco seedlings will develop well, while others will develop poorly due to failure to treat diseases in time. This requires the use of a grid-type tobacco seedling grower that can prevent tobacco root and stem diseases.

[0003] However, in the prior art, the use of grid-type tobacco seedling cultivation cannot satisfy the requirement of accurate nutrition supply for a single tobacco seedling, and it is not convenient to uniformly and continuously input nutrient solution in a stable manner. Utility Model Content
