specific Embodiment approach 1

[0020]DETAILED DESCRIPTION One: CombinationFigure 1 ~ 3 In this embodiment, the present embodiment includes a T-type piston rod 1, a fixing screw 3, a pressure shanning 4, a support plate 5, a sample cartridge 6, a piston 8, and a quantitative ring 10, and the electrode handle 4 is disposed above the sampling cartridge 6, two A support plate 5 is located between the electrode 4 and the sampling cartridge 6, and the two support plates 5 are symmetrically disposed on both sides of the sampling cartridge 6, and the upper end of the support plate 5 is welded to the electrode, the lower end and the sampling cartridge of the support plate 5. 6 Welding, the central hole 2 in the center of the electrode 4 is provided, and a horizontal threaded hole 4-1, a horizontal threaded hole 4-1, a piston 8, and a quantitative ring 10 are arranged on the plunger 4, and the piston 8 and the quantitative ring 10 are arranged. Inside the sample cartridge 6, a vertical threaded hole 7 is provided at the ce...

specific Embodiment approach 2

[0021]DETAILED DESCRIPTION 2: CombinationFigure 1 ~ 7In this embodiment, the present embodiment is achieved by the following steps:

[0022]Step 1, mounting the quantitative ring 10: Take a quantitative ring 10 into the sampling cart 6 from the lower end of the sampling cartridge 6, and adjust the position of the piston 8 to close the piston 8 on the upper edge of the quantitative ring 10, quantitative ring. 10 The lower edge of the lower end is equal to the lower end of the sampling cartridge 6, and the position of the fixed screw 3 is tightened by the T-piston rod 1;

[0023]Step II. After the sequetime: After the assembly is completed, the hands hold the plug 4 to vertically in the sampling area, deep into the soil 10cm ~ 15cm, hands holding the electrode handle 4 to pull out the sampling cartridge 6 from the soil, use The blade 15 scrateches the soil at the lower edge of the sampling cartridge 6, loosen the fixing screw 3, and push the T-type piston rod 1 to introduce the quantitative...

Abstract

According to the quantitative sampling device and method for the soil animals, a pressing handle is arranged above a sampling cylinder and connected with the sampling cylinder through a supporting plate, a piston and a quantitative ring are arranged in the sampling cylinder in an up-and-down mode, and the lower end of a T-shaped piston rod penetrates through a round hole and is in threaded connection with a vertical threaded hole. The method comprises the following steps: 1, adjusting a piston by a T-shaped piston rod to enable the upper edge of a quantitative ring to cling to the piston and the lower edge of the quantitative ring to be flush with the lower end of a sampling cylinder; 2, holding the pressing handle by two hands to vertically press the sampling cylinder into a sampling area, pulling out the sampling cylinder from the soil after the sampling cylinder goes deep into the soil for 10cm, scraping the soil at the lower edge of the sampling cylinder by using a scraper blade, unscrewing a fixed screw rod, and pushing a T-shaped piston rod to push a quantitative ring out of the sampling cylinder; and 3, after the quantitative ring is pushed out by 1cm, buckling an upper sample cover and a lower sample cover, continuously pushing the T-shaped piston rod, after the quantitative ring is pushed out of the sampling cylinder, buckling the upper sample cover, pasting a label on the packaged soil column, and putting the packaged soil column into a circular groove in a sample disc. The device and method are used for collecting soil.

Description

Technical field[0001]The present invention relates to a sample acquisition device, and more particularly to a soil animal quantitative sampling device and method.Background technique[0002]The soil contains a quarter of biodiversity in the world, and is the most abundant ecological environment on earth. Although the soil animals are small, they have a variety of riches, and play an important role in maintaining terrestrial ecosystem carbon nitrogen circulation. It is the most abundant biological component of land ecosystems, almost involved in all underground ecological processes. The diversity of soil animals and distribution patterns can indirectly reactive soil's physical and chemical properties, and play a crucial role in decomposition organic matter, nutrient cycle, improve soil structure and soil fertility. Based on soil animals impact on production, environment, it is increasingly concerned in the fields of zoology, ecology, soil learning and environmental protection, and ther...
