Description

A device for collecting above-ground biomass of alpine grassland

Technical Field

The utility model relates to the technical field of grassland collection equipment, in particular to a device for collecting above-ground biomass of alpine grasslands.

Background technique

Grassland is an important terrestrial ecosystem with a wide distribution and a large biomass. It plays an important role in the global carbon cycle. The aboveground biomass of grassland can reflect the development potential of grassland. It is an important indicator of grassland growth and carbon cycle of grassland ecosystem. It is of great significance to the health assessment, sustainable development and optimal management of grassland ecosystem.

Currently, the commonly used sampling tools are scissors or sickles. In order to keep close to the ground, the operator is easily cut by the weeds on the ground. At the same time, the cooperation of multiple people is required, the collection efficiency is low, and the sampling is time-consuming and labor-intensive. In addition, when collecting herbaceous plants, the fine samples are easily splashed, resulting in incomplete biomass collection and causing loss of statistical grassland biomass. If a sampling separation box device is used, it will have disadvantages such as being too heavy, occupying a large area, and not adapting to the complex terrain of the plateau. The only portable sampling devices on the market are small lawn mowers. If used in plateau wetland grasslands, due to the complexity and diversity of vegetation and sample plots, as well as the messy plants in the sample plots, the lawn mower blades are easily entangled and stop working, and the ideal effect cannot be achieved.
