Description

Technical Field

[0001] This invention relates to the field of tobacco planting machinery technology, and in particular to a device for removing film, covering soil, and applying fertilizer. Background Technology

[0002] Once tobacco plants are planted in rows and reach the rosette stage, they enter a rapid growth period. During the seedling stage, they require mulching. As the plants mature, the mulch needs to be removed and soil mulched around the roots to promote root growth. Mulching involves removing the plastic film covering the rows to improve soil permeability, then turning over the soil between the rows and covering the roots with it to encourage root development. Simultaneously, fertilizer is applied about 10cm below the roots to provide sufficient nutrients for the plants' growth.
