The pursuit of green environmental protection in modern agriculture is a popular way of planting under the experience of past predatory planting. Plant disease is inevitable when planting plants. In the past, pesticides were used to treat diseases, but this not only polluted the environment, but also harmed the edible fruits, causing pesticide residues. In the process of disease prevention and control, the agricultural instruments currently being implemented mainly include spore trapping devices . Under the premise of green ecological agriculture, the application fields of spore trapping instruments are becoming more and more extensive.
However, the emergence of too many spore trapping instruments will inevitably lead to market confusion, and products with low quality and low price will not be guaranteed. How we should identify high-quality manufacturers and products has become a big problem.
Previous capture methods and traps used a Vaseline slide or glue stick as a capture carrier. Neither of these capture vectors is suitable for continuous capture. Taking the paste method in the method for measuring sporulation, the instrument uses a transparent tape as a capture carrier.
The scotch tape is soft and bendable, and the sampling length is relatively unrestricted, suitable for continuous sampling. Because the sampled scotch tape is taken back into the room, it needs to be adhered to the glass slide with phenolic phenol as a floating carrier. The spores are counted under the microscope. Because the width of the slide is 26mm, 20mm wide transparent tape is used as the capture tape. .
In order to achieve continuous spore capture, the data for aerial spores at each time period should be recorded on different areas of the capture zone. Also for the convenience of counting under the microscope, the data of one hour of aerial spores was designed to be recorded on the length of the capture tape of 2 mm, that is, the sampling area per hour was 20 mm 2 mm. The instrument works for 7 consecutive days, so the minimum length of the capture belt can be calculated to be 336 mm.
In the circuit design, linearization processing circuit and temperature and humidity compensation circuit should be added, or by means of single-chip microcomputer system, processing and correction by software table lookup method (software sensor correction compensation function can reduce instrument power consumption).
