Description

Well cellar filling and sealing topdressing device Technical Field The invention relates to the technical field of agricultural appliances, in particular to a well cellar filling and sealing topdressing device. Background At present, the growing trend of the tobacco control call is that the development of the tobacco industry is in a severe situation, so that the improvement of the quality of tobacco leaves is important. The well cellar type transplanting technology for flue-cured tobacco is an improved seedling transplanting technology under a film, and the principle of the well cellar type transplanting technology is that along with the change of external temperature and humidity, the water content of soil in the well cellar is evaporated or condensed by the hydraulic gradient generated by the well cellar, so that the relative stability of the temperature and humidity in the well cellar is maintained, and a suitable growing temperature and humidity and nutrition environment are provided for tobacco seedlings in the optimal transplanting season. When flue-cured tobacco well cellar type transplanting technology is carried out, a plastic film is firstly required to be covered on each soil ridge of a tobacco field, soil is covered and pressed on inclined planes on two sides of the plastic film (positioned on two sides of the soil ridge), then a puncher is used for punching holes on the soil ridge, tobacco seedlings are transplanted in holes, when the tobacco seedlings grow to a certain degree, the holes originally punched on the plastic film are required to be enlarged, and well cellar is required to be filled and sealed for topdressing.
