Embodiment Construction

[0017] like figure 1 As shown, a soil nematode separation and sedimentation device includes an operation table 1, a separation pool 2 is provided on the top of the operation table 1, the mouth of the separation pool 2 is flush with the table top of the operation table 1, and a square is set under the operation table 1 table. Box-shaped settling tanks 3,4. In order to prevent dirt from splashing out, a dodge door (not shown) is provided on the side wall of the console 1 .

[0018] Settling tank 3 is provided with baffle 303, the top edge of baffle 303 is slightly lower than the mouth edge of settling tank 3, it divides settling tank 3 into two parts, respectively settling tank 301 and buffer tank 302, and the bottom surface of the separation tank A water outlet hole 202 is provided, and the settling tank 301 is located below the water outlet hole 202 . Since the water flows into the sedimentation tank 3 from a high place, the flow velocity is very high. Setting the baffle pla...

Abstract

The invention discloses a separation and precipitation device for nematodes in soil, comprising a separation pool having a built-in strainer, a water outlet arranged on the bottom surface of the separation pool, a first precipitation pool arranged vertically below the water outlet, and a second precipitation pool which is arranged near the first precipitation pool at the same horizontal level as the first precipitation pool and communicated with the first precipitation pool through pipes, wherein, the height of the first precipitation pool is larger than that of the second precipitation pool. According to the invention, by arranging two precipitation pools communicated with each other through pipes below the separation pool, all soil and nematode cysts can be intercepted, so that the biological contamination and sewer plug can be prevented. The device makes full use of the self-mastery of water to work, and has the advantages of environment protective and energy saving.

Description

technical field [0001] The invention relates to the technical field of agricultural scientific research, in particular to a soil nematode separation and sedimentation device. Background technique [0002] Soil nematodes refer to plant parasitic nematodes and other soil-dwelling free-living nematodes that live in soil or have at least one developmental stage in soil in their life history. They are generally mainly distributed in moist soil rich in organic matter and around plant roots. [0003] The direct harm of plant parasitic nematodes is mainly the flower buds, leaves, stems and roots of plants. Many types of nematodes, such as root-knot nematodes and cyst nematodes, can infect most vegetables and crops, resulting in reduced quality, reduced yield, and even crop failure, which seriously hinders agricultural production in our country. The main indirect hazards are, on the one hand, the surface wounds caused by nematodes increase the chance of fungi and bacteria invading ...
