Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, and particularly relates to a leveling device for the surface of a flue-cured tobacco seedling-raising pool. Background Art

[0002] At the present stage, the main seedling-raising methods for flue-cured tobacco are wet seedling-raising and floating seedling-raising. For both methods, it is necessary to level the surface (ground) of the seedling-raising pool. Especially for wet seedling-raising, since a large amount of nutrient solution is not required, the height of the nutrient solution in the seedling-raising pool is 2 cm - 5 cm to keep the substrate in the seedling tray moist, and the water management is relatively strict. Therefore, the leveling of the surface of the seedling-raising pool is particularly important.

[0003] To facilitate the leveling operation, river sand is usually paved in the seedling-raising pool, and then it is leveled by scraping with a wooden board through visual observation, or further adjusted for level by filling the pool with water to check the water level.

[0004] In the prior art, for the existing seedling-raising pool, the operator needs to use a wooden board to scrape it flat multiple times according to the number of rows and columns of the seedlings, and the efficiency is low. The operator using the wooden board cannot adapt to seedling-raising pools of different sizes. Moreover, when scraping, because the area of the seedling-raising pool is large, the operator needs to step into the seedling-raising pool to scrape, which is easy to trample on the tobacco seedlings. In addition, when the operator uses the wooden board to scrape, there is often a problem of insufficient flatness, resulting in one side of the seedling tray being high and the other side being low. The high side is likely to cause the substrate not to absorb the nutrient solution, easily resulting in the phenomenon of dry holes, and the tobacco seedlings in the dry holes will be hindered in growth or even die. While the low side is likely to cause the substrate to have a large water content, the tobacco seedlings have high humidity, and the substrate is prone to grow moss, competing with the tobacco seedlings and seriously affecting the growth of the tobacco seedlings. Summary of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a leveling device for the surface of a flue-cured tobacco seedling-raising pool, which can effectively solve the above-mentioned deficiencies in the prior art.
