A grassland litter decomposition device for grazing experimental area

Abstract

The invention discloses a grassland litter decomposing device used in a grazing test area. The device comprises an annular positioning plate; the upper surface of the annular positioning plate is provided with an isolation net, and the inner side surface of the annular positioning plate is provided with a cross-shaped partition plate; the outer side surface of the cross-shaped partition plate is provided with isolation compartments, and the upper surface of each isolation compartment is provided with mounting grooves; the central part of the upper surface of the cross-shaped partition plate isprovided with a supporting rod, and the upper end surface of the supporting rod is provided with a tray; the upper surface of the tray is provided with a temperature sensor and a humidity sensor; andthe left end of the outer side surface of the annular positioning plate is provided with a first supporting plate, and the upper surface of the first supporting plate is provided with an operation box. The grassland litter decomposing device used in the grazing test area disclosed by the invention has a compact structure, is convenient to install, and can effectively assist a user to decompose and detect grassland litter in the grazing test area; and arrangement of the isolation net can effectively prevent livestock from stepping into the test area, solar energy can be converted into electricenergy through a solar cell panel, and arrangement of the isolation compartments facilitates experimental comparison.

Description

technical field [0001] The invention relates to the technical field of forage decomposition experimental equipment, in particular to a grassland litter decomposition device used in a grazing test area. Background technique [0002] The decomposition of grassland litter is one of the key processes in the nutrient cycle of the ecosystem, which plays a decisive role in improving the physical and chemical properties of the soil, improving soil fertility and plant productivity. In order to avoid the light litter on the grassland being blown away by the wind, the litter is often put into a decomposition bag made of nylon mesh bag and placed in the field for decomposition under natural conditions. However, when carrying out litter decomposition experiments in grazing experimental plots, mesh bags are often damaged by livestock, or even lost, which seriously affects the normal operation of the experiment. At the same time, the material of the nylon mesh bag is relatively hard, whic...

Problems solved by technology

However, when carrying out litter decomposition experiments in grazing experimental plots, mesh bags are often damaged by livestock or even lost, which seriously affects the normal operation of the experiment.

At the same time, the material of the nylon mesh bag is relatively hard, which is not suitable for the storage of grassland litter. Stipa type litter is thin and hard, not only difficult to lay evenly, but also it is not easy to carry out grassland litter by using nylon mesh bag to hold grassland litter. Sampling observation
