Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a test strip and storage device for detecting available phosphorus in soil. Background Technology

[0002] Soil testing sometimes requires determining the available phosphorus in the soil. Currently, the most common method for rapid determination of available phosphorus in soil is to use a reagent kit. This kit uses sodium bicarbonate to extract available phosphorus from the soil, mixes the extracted phosphorus with molybdenum, antimony, and scandium for color development, and then determines the available phosphorus content of the soil sample based on the color of the resulting mixture.

[0003] In the prior art, Chinese patent CN202321799415.0 discloses a soil available phosphorus detection kit. This kit addresses the common problem that after testing soil for available phosphorus, workers often wipe the inside of the detection compartment with a paper towel, leaving paper towel residue inside and causing debris buildup. The kit includes a box body with a groove plate fixed to one side. This method utilizes the coordinated installation of a brush rod and a connecting rod to quickly remove residue from the detection compartment at the top of the box, preventing it from affecting the device's detection of available phosphorus and improving its effectiveness. Furthermore, the coordinated installation of a perforated block and a horizontal column allows the horizontal plate to slide stably on the top of the support plate, better controlling the brush rod's removal of residue from the detection compartment.

[0004] The soil available phosphorus detection kit provided by the aforementioned patent extracts available phosphorus from the soil and then determines the content of available phosphorus by colorimetry. However, the test strips in existing kits are mostly individual sheets of paper, which can easily cause the solution to spill when dripping solution onto the test strip. At the same time, the test strips are not convenient for colorimetric analysis, and the individual test strips are also inconvenient to store. Utility Model Content

The colorimetric area 12 is used for convenient colorimetric comparison of the test strip 3. A small tray 2 is provided inside the installation groove 11, which facilitates the installation and stable use of the small tray 2. The test strip 3 is placed inside the small tray 2. This structure prevents solution from spilling when solution is dripped onto the test strip 3. Furthermore, a pressure cap 4 is provided at the opening on the outer side of the small tray 2, which presses the test strip 3 tightly; this structure can ensure that the test strip 3 is stable inside the small tray 2; the storage device includes a sleeve box 5, a pull-out box 6, and a limiting plate 7; the limiting plate 7 is set inside the pull-out box 6, and the test strips inside the pull-out box 6 are inserted into the limiting plate 7; the sleeve box 5 is fitted on the outside of the pull-out box 6, and is used to store the test strips inside the pull-out box 6; the pull-out box 6 is convenient for placing test strips, convenient for storing test strips, and also convenient for carrying and using the test strip itself.

[0030] like Figure 3 As shown, the small tray 2 is glued to the mounting groove 11, which ensures that the small tray 2 is stable on the colorimetric card 1. Furthermore, the top and bottom of the opening of the small tray 2 are symmetrically provided with slots 21, which are used to connect with the pressure cap 4.

[0031] like Figure 4 As shown, the front and rear ends of the test strip 3 are glued with pressure blocks 31.

[0036] Working principle: When in use, pull out the pull-out box 6 and remove the test strip. Then, the operator opens the pressure cap 4 and drips the solution used to detect available phosphorus onto the test strip 3 inside the small tray 2. The test strip will change color upon contact with the solution. The operator then observes the final color of the test strip and compares it with the colorimetric area 12 to determine the available phosphorus in the soil. If the test strip needs to be taken back after testing, the pressure cap 4 is used to seal the small tray 2. Then, the lower part of the colorimetric card 1 of the entire test strip is inserted into the limiting hole 71, and the pull-out box 6 is pushed into the inner side of the sleeve 5.
