Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to a portable ground film side hole puncher. Background Art

[0002] Film mulching cultivation is to cover the ground with transparent plastic film, sow seeds under the film and protect the growth of crop seedlings, and then uncover the film after the temperature warms up, so that the seedlings can grow under normal climatic conditions. In the middle and late stages of film cultivation, some areas need to cover the film throughout the growth period due to insufficient accumulated temperature. However, covering the film throughout the growth period cannot guarantee the water demand of crops when the rainy season comes, so it is necessary to use a corresponding film puncher to punch holes in the side of the film, which helps crops absorb water in time and prevents further evaporation of water, so that crops can not only maintain sufficient accumulated temperature in the middle and late stages of growth, but also ensure water absorption.

[0003] For example, the utility model patent with application number 202320861786.0 discloses a mulch hole puncher with a supporting function, including a supporting frame, universal wheels are arranged at the four corners of the bottom surface of the supporting frame, and a punching mechanism is arranged on the top of the supporting frame.
