Experimental device for detecting corn germination rate

Abstract

The invention relates to an experimental device for detecting corn germination rate. The experimental device comprises a transparent box body, a transparent box cover and a water absorption plate; thetransparent box cover is placed at the upper end of the transparent box body; the water absorption plate is horizontally placed inside the transparent box body; the water absorption plate is providedwith a plurality of planting holes; the experimental device further includes a touch panel, a micro pressure sensor and a PLC, and the touch panel is placed in the transparent box body; the micro pressure sensor is placed at the upper end of the transparent box cover; the signal input end of the micro pressure sensor is connected to the control panel through a circuit; the PLC is connected with the signal output end of the micro pressure sensor; the PLC is connected with a display; the experimental device further includes an atomizer which is placed at the upper end of the transparent box cover; the transparent box body is internally provided with a tube body; the mist outlet end of the atomizer is connected with the tube body; and a plurality of mist outlet holes are formed in the lowerend part of the tube body. Compared with the prior art, the germination rate detection process is high in degree of automation, the calculation data are accurate, and the convenience is improved; moreefficient and uniform germination of corn seeds is guaranteed; and the detection speed and accuracy are guaranteed.

Description

technical field [0001] The invention relates to the technical field of planting and germination, in particular to an experimental device for detecting the germination rate of corn. Background technique [0002] In the prior art, such as a seed germination rate detection incubator with application number 201520327663.4, which includes a box body, a glass door hinged with the box body, a monitoring device installed in the box body, and a loading tray is placed at the bottom of the box body.

Problems solved by technology

It can be seen from the above records that when the germination rate of seeds is detected in the prior art, the industrial camera is mainly used to take pictures of the images, and then the color in the image is analyzed to obtain the germination rate of the seeds. However, when the detected corn seeds and When the color difference of corn seedlings is not large, it is easy to cause detection errors, so it is necessary to solve these problems
