Description

TECHNICAL FIELD

[0001] The utility model relates to herbicide residue detection technical field, concretely is easy to use type herbicide residue detection test paper structure. BACKGROUND

[0002] Weeds are plants that have survived for a long time under local crop, cultivation, farming, climate, soil and other ecological and production conditions, which harm crops in different ways, compete with crops for nutrients, water and light, spread diseases and pests, and reduce crop yield and quality, and weed control will also increase the labor and production cost of farmland management. Therefore, herbicides are an important guarantee for stable and efficient agriculture. However, the herbicide residues in the soil will pollute the land to varying degrees, causing soil degradation and affecting production, so the soil needs to be managed periodically, and the type of herbicide residue in the soil needs to be detected before management. The existing test paper is usually a test paper strip wrapped in a shell, which is provided with a sample hole and an observation window. This test paper needs to be used as soon as possible to avoid invalidation, and other equipment needs to be used to quantitatively sample and vertically drop into the sample hole to ensure the accuracy of the test results, which is inconvenient to use. SUMMARY

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an easy-to-use herbicide residue detection test paper structure that can effectively solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an easy-to-use herbicide residue detection test paper structure, which comprises an outer shell composed of an upper shell and a lower shell, a test paper strip clamped between the lower shell and the upper shell, a sample hole, an observation window and a detection mark provided on the upper shell, a sealing transparent cover plate provided at the observation window, a sealing film provided at the sample hole, a measuring cup provided outside the sample hole, and a removable puncture strip provided at the bottom of the lower shell.

[0005] As a preferred technical scheme of the utility model, the measuring cup is made of transparent material, and a scale bar is provided on the cup wall.

[0006] As a preferred technical scheme of the utility model, the lower shell and the upper shell are formed by injection molding, and the measuring cup is fixed at the sample hole of the upper shell by adhesive.

[0007] As a preferred technical scheme of the utility model, the puncture strip is fixed to the bottom surface of the lower shell by a tearable strip.

[0008] As a preferred technical scheme of the utility model, the puncture strip is pasted to the bottom surface of the lower shell by a tearable double-sided adhesive tape.

[0009] Compared with the prior art, the easy-to-use herbicide residue detection test paper structure has the advantages that the sealing effect of the shell is optimized, the probability of invalidation of the test paper strip after long-time contact with air is reduced, a transparent measuring cup is arranged at the sample adding hole, accurate sample adding to the sample adding hole can be realized without relying on additional quantitative sampling equipment, the detection accuracy is ensured, and therefore the test paper structure has the characteristics of good stability, convenient use and high accuracy.
