Description

Technical Field

[0001] The utility model relates to the technical field of garden shears, in particular to a mine reed pruning device. Background Art

[0002] After mining, mines often form irregular areas, which in turn form a large number of potholes. After rainfall, many sunken areas will accumulate a lot of rainwater, and then perennial tall upright herbs and grass plants such as reeds will rapidly expand and multiply. Reeds are perennial herbs with grape-like rhizomes. Because reed rhizomes are very developed, they will quickly occupy the growth resources of other plants, gradually forming colony-building plants, which conflicts with the concept of restoring plant diversity in mines.

[0003] In addition, since reeds are deeply rooted in the ground, they cannot be eradicated even by turning the soil, digging and plowing. At present, the commonly used method of removing reeds is that one person first cuts the reed stems on the surface with scissors, and then another person applies or sprinkles herbicides on the cut reed stubble, causing the roots to rot and die under the action of the drug. When one herbicide cannot effectively eradicate the reeds, another herbicide needs to be applied or sprinkled on the reeds again by humans. Although this method is effective, it is labor-intensive, time-consuming and labor-intensive.
