Plant Disease Rapid Diagnosis Instrument

1、 Overview:

Bacteria, fungi, and viruses are the main causes of crop diseases. These pathogenic microorganisms generally infect plants through stems, leaves, roots, fruits, etc. Although most diseases are relatively easy to control in the early stages of infection, they are generally not easily detected by people. Once the disease occurs, prevention and control are not only difficult but also ineffective, resulting in reduced crop yields or even complete crop failure. How to detect and prevent diseases in the early stages of onset is particularly important for preventing and controlling the occurrence of diseases.

The detection of plant diseases is a complex chemical and physical process, which has always been a goal pursued by people from the laboratory to practical applications. This instrument can quickly analyze and determine the types of various crop diseases. This provides a scientific theoretical basis for how to prevent and treat diseases and medication, bringing great convenience to farmers and farmers.

2、 Detection principle:

According to biophysical methods, the membrane sites of generally healthy plants are located at-50mvOn both sides, the resistance of the external liquid film is105Ω/cmLeft and right, the membrane capacitance is basically maintained at1ufOnce crops are infected, it will inevitably lead to changes in molecular vibrational spectra and an increase in membrane potential, causing changes in the inoculation of different pathogens. Based on this principle, the types and types of diseases can be distinguished through conductivity and light diffraction methods, which is the most advanced technology worldwide.

3、 Technical indicators and working environment:

3. Recording method: Printed by thermal printer.

4. Display mode:240*60Dot matrix patternLCDDisplay.

5. Recording paper: thermal printing paper,57mm.

6. Work environment:

(1) Working temperature:0°-40°;

(2) Relative humidity:RH≤85%;

(3) Stay away from strong electromagnetic interference sources and avoid direct exposure to strong light.

7. Working power supply:AC220V±10%，50Hz±2Hz

8. Power:& le;30W

9. Net weight:& le;3kg

4、 Operating procedures:

1. Turn on the power, the instrument starts self checking, the detection slot slowly moves out, and waits for testing.

2. Cut the roots, stems, and leaves of the plants into small pieces and place them in a plastic bowl, with a quantity of approximately one-third to one-fifth of the bowl's capacity.

3. Take equal amounts of five indicator liquids using droppers, drip them into a plastic bowl containing plants, stir evenly, and place2-3Minutes to be tested.

4. Rinse the dropper with clean water and take a small amount of the mixture of indicator and plant debris, evenly apply it to the indicator strip, and place the indicator strip in the testing slot with the colored strip facing up.

5. Gently press the test button, and after hearing a beep, the tester begins to detect. The test slot and indicator bar slowly move into the instrument, and then return. At this point, the instrument begins to automatically print the test results.

5、 Result analysis:

project Normal reference value Pathological reference value
a virus －－－－－－－－－－－－－－－－&ge;493－－－－－－－－－－－－－－－－－－－<262
Fungal disease －－－－－－－－－－－－－－－－&ge;485－－－－－－－－－－－－－－－－－－－<266
Bacterial disease －－－－－－－－－－－－－－－－&ge;420－－－－－－－－－－－－－－－－－－－<249
Fungal virus complex disease －－－－－－－－－－－－&ge;472－－－－－－－－－－－－－－－－－－－<228
Fungal bacterial complex disease －－－－－－－－－－－－&ge;502－－－－－－－－－－－－－－－－－－－<258
Viral bacterial complex disease －－－－－－－－－－－－&ge;511－－－－－－－－－－－－－－－－－－－<316
Fungal bacterial viral complex disease －－－－－－－－－－&ge;412－－－－－－－－－－－－－－－－－－－<147
Residual amount －－－－－－－－－－－－－－－－&ge;096－－－－－－－－－－－－－－－－－－－<063
Trace element deficiency syndrome －－－－－－－－－－－－&ge;372－－－－－－－－－－－－－－－－－－－<236
photosynthetic rate －－－－－－－－－－－－－－&ge;505－－－－－－－－－－－－－－－－－－－<311
Leaf growth －－－－－－－－－－－－－－－&ge;438－－－－－－－－－－－－－－－－－－－<402

If the test value is greater than the reference value, it indicates normal growth. If it is lower than the reference value, medication can be used as a reference.

6、 Medication Guide:

The test values are reference values for guiding drug use. The lower the test values, the more severe the crop disease or weaker the plant growth. In addition to using fungicides, foliar fertilizers should be applied, and the dosage should not exceed the limit value of a certain drug, otherwise it will cause drug damage.

7、 Attention:

1. Avoid testing in areas with direct sunlight.

2. Pay attention to electrical safety, air humidity should exceed85%It should be stopped from use.

3. The instrument should be stored in a ventilated, dry, and dark location, and covered with a dry cloth.

4. The test slot and print head should be kept clean.

8、 Instrument matching:

1. One host 2One box of test strips 3Fuse2individual 4One power cord 5A roll of printing paper 6Five types of indicator liquids
