Embodiment Construction

[0016] Place the 40W incandescent lamp in the 18cm spotlight to make the required lamp 2.

[0017] according to figure 1 As shown, the light fixture 2 is suspended on the cross bar 6. The aluminum-plastic perforated plate 4 with a diameter of 8 cm is placed flat in the glass funnel 3 of 18 cm, and then the collected soil samples are carefully poured on it and spread flat. Place a 100ml beaker 5 below the funnel 3, and fill 10ml of 75% alcohol. Two sets of separation systems consisting of lamps 2, funnels 3, and beakers 5 equipped with aluminum-plastic perforated plates 4 were assembled on the same separator frame composed of cross arms 1 and poles 9. After assembling according to the above process, adjust the height of the cross bar 6 through the chute 7, so that the lamp 2 is vertically suspended at 5 cm above the funnel 3, turn on the power, and after heating for 24 hours, the soil animals are separated from the soil sample and collected in a beaker 3 in.

Abstract

The invention belongs to the agriculture technique to provide a soil-animal divider. It comprises: a dividing support, a lamp, a funnel, a plastic-aluminum porous plate, a beaker, a rail, a runner and a funnel support. Wherein, the dividing support is formed by poles and beams, while the funnel support horizontally fixed is mounted on the poles and the runner is arranged between the beams and funnel support; the rail is connected on the runner of pole; the funnel is mounted on the funnel support; the plastic-aluminum porous plate is arranged on the middle-lower part of the cone of funnel; the lamp is mounted on the rail; and the beaker is under the funnel. The lamp, the funnel with plastic-aluminum porous plate and the beaker form the dividing system from upper to lower. The invention can effectively control the temperature and save energy via improve the structure of former divider, with simple operation, to improve the control ability and the dividing efficiency.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a soil separator, in particular to a soil animal separator. Background technique [0002] There are tens of thousands of soil animals living in the soil. They are an important part of the soil ecosystem. They participate in the decomposition of biological residues, change soil properties, and affect the formation and development of soil and the material cycle and energy of the ecosystem. Mobility matters. For the collection of soil animals, the Italian scholar Berlesc invented the insect drying funnel in the early 20th century, which was improved by Tullgren and widely used. It is called the Tullgren method or the dry funnel method. It is mainly used for the separation and extraction of small and medium-sized soil animals with a body length of 0.2-2mm. At present, scholars at home and abroad still use the Tullgren method to separate small and medium-sized soil animals. Tullgr...
