Description

  The present invention relates to a pre-harvest treatment apparatus for vegetables under snow that grow on the surface in winter.

Forms that grow under snow in winter, such as spinach and cabbage, are commonly used in the region based on the knowledge that sweet and delicious vegetables can be obtained depending on the local weather conditions.
According to this growth method, the plant grows under the so-called snow and becomes a harvest time, and the snow removal work is forced before the harvesting work.

  In the past, manual work required snow removal, which required heavy labor and improved mechanization. In addition, although the snow removal apparatus using an agricultural tractor is well-known (for example, patent document 1), it does not presuppose the harvest of the vegetables under snow.
