Living plant leaf stoma imaging viewer

Abstract

The invention discloses a living plant leaf stoma imaging viewer. In the viewer, a power module is used for providing electric energy for the whole system, a 4.3-inch capacitive touch screen is connected to an MCU minimum system module through a flexible flat cable and used for achieving man-machine interaction, a clock module is connected to the MCU minimum system module and used for providing a time reference for the whole system, the input end of a voltage detecting module is a lead storage battery in the power module, the output end of the voltage detecting module is connected to an AD interface of the MCU minimum system module and used for detecting residual electric quantity of the lead storage battery in the power module, and a steering gear shading module is connected to a PWM interface of the MCU minimum system module and used for controlling the steering direction of a shading plate. Proper living plant leaf stoma image observation is achieved, in other words, a leaf stoma image is obtained on the premise that a leaf is not separated from a plant body and carries out normal photosynthesis.

Description

technical field [0001] The invention relates to a living plant leaf stomata imaging observer, in particular to an observer for acquiring stomata images of plant leaves without affecting the normal physiological activities of the plant leaves. Background technique [0002] Today, the issue of global climate change is becoming increasingly prominent. As the main body of the terrestrial ecosystem, the forest has the characteristics of repeatability and regeneration, and has the dual functions of carbon source and carbon sink, especially the function of carbon sink, which can not only greatly alleviate the trend of climate warming, but also effectively offset the CO 2 Emissions, promoting the balance of carbon in the earth's ecosystem. CO offsetting through forest carbon sinks 2 Emissions have become an important part of the international climate convention, and have attracted extensive attention from governments and scientists around the world. In recent years, my country's ...

Problems solved by technology

[0003] At present, the existing devices or methods for observing leaf stomata cannot accurately observe plant leaf stomata without affecting the normal physiology of plants.

At present, there are roughly four methods for observing stomata. One is to tear the epidermal tissue of the leaf and make a specimen for observation under a biological microscope. This method interrupts the normal physiological activities of the leaf in a "violent" way. The other is to remove the leaf from the plant. In the laboratory, the observation of the stomata is realized by scanning the microscope. Although this method does not destroy the leaf tissue, it also terminates the normal physiological activities of the leaf. The change of time tends to close, resulting in inaccurate observation results; the third method is to quantitatively detect the opening and closing of stomata using a gas meter. Although this method does not need to remove the leaves from the plant, the fixture of the gas meter affects the normal operation of the plant leaves. Photosynthesis will also lead to inaccurate measurement results; the fourth method uses electron microscope observation. Although this method can realize the stomatal observation of living plants, it affects the normal photosynthesis of plants, and the size of the observed plants is limited. Observation The location is limited and it is not conducive to long-term outdoor work
