Land ecosystem carbon cycle research sampling device

Abstract

The invention provides a land ecosystem carbon cycle research sampling device, which belongs to the technical field of soil detection, and comprises a soil sampling cylinder body, a soil sampling handle, a pedal plate, a movable cover plate and a movable cover plate semi-automatic opening device, wherein a pedal is fixedly connected to the top end of the soil sampling barrel, a soil sampling knifeis fixedly connected to the bottom end of the soil sampling barrel, a sampling window extending along the axis of the barrel is formed in the side wall of the barrel, and scale marks for displaying the sampling depth are engraved in the outer wall, close to the sampling window, of the soil sampling barrel; the center of the upper end surface of the pedal is fixedly connected with a soil samplinghandle through a connecting rod, and the soil sampling handle is located right above the pedal; the upper surface and the lower surface of the soil sampling handle are both fixedly connected with a plurality of anti-skid rubber protruding strips, the sampling window is tightly covered with a movable cover plate, and the movable cover plate is connected with the pedal through a movable cover platesemi-automatic opening device, so that soil can be sampled at any depth, the accuracy of experimental results is improved, and smooth sampling is facilitated.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and specifically relates to a sampling device for carbon cycle research of terrestrial ecosystems. Background technique [0002] Carbon is a common element. Carbon is not only an essential component of organic substances, but also an important component of inorganic substances. Carbon can form a rich variety of organic substances together with nitrogen, hydrogen and phosphorus. The rapid exploitation of resources caused by the rapid development of society, the excessive use of soil, and the discharge of waste will all bring a burden on the ecological environment that exceeds the ability of the ecological environment to regulate itself, causing changes in the global ecological cycle system that affect the whole body. In order to protect The ecological environment requires real-time detection of the ecological environment. Among them, the carbon cycle research of terrestrial ecosystem ref...

Problems solved by technology

One is that the existing soil-taking device is provided with a number of sampling ports equidistant in the axial direction on the soil-taking cylinder so as to take soil samples of different depths, but the sampling ports have the following technical defects in actual use: 1. One is that the soil sampling depth is limited by the setting of the sampling port, and soil sampling at any depth cannot be realized; the other is that when the soil-taking cylinder is pulled out from the soil, the soil outside the soil-taking cylinder enters the soil-taking cylinder through the sampling port, which affects The accuracy of the experimental results; the third is that for harder soil, the resistance of the soil borrowing cylinder to penetrate into the soil is relatively large; the fourth is that the plant roots in the soil will hinder the soil sampling cylinder from penetrating into the soil for sampling
