Embodiment 1

[0046] First, use the GPS module to locate the location of the measured plant, record the latitude and longitude information, or input the number information of the plot where the measured stem is located; then set the measurement target, for example, to obtain the required thrust value when the stem inclination angle is 40 degrees, Or obtain the tilt angle of the stalk under the thrust of 1N; then use the clamping device to clamp the measured plant, and push it perpendicular to the plant stalk at an approximately uniform speed to reduce the error caused by the acceleration movement on the thrust; when it reaches the preset angle value (40 degrees) or thrust value (1N), the device will sound an alarm, pop up an alarm interface to remind the user, end this test, and display the force, angle value, time of this test, and the tested value on the LCD screen. Information such as stem species, latitude and longitude values, or plot numbers are stored and stored; the stored data can b...

Embodiment 2

[0048] First, use the GPS module to locate the location of the measured plant, record the latitude and longitude information, or input the land number information of the measured stem; then set the measurement target, for example, the acquisition range of the angle is 0 to 40 degrees, and the Record the corresponding thrust every time the stalk is bent by 0.5 degrees; then, use the clamping device to clamp the measured plant, and push it perpendicular to the plant stalk at an approximately uniform speed to reduce the error caused by the acceleration movement on the thrust; reach the preset angle value , the device will remind the user to end the test; substitute the measured angle and force data into the lodging resistance strength model to obtain the lodging resistance strength index; display the lodging resistance index and the time of the test on the LCD screen , the measured stalk variety, latitude and longitude values ​​or plot number and other information and store them; ...

Abstract

The invention relates to the technical field of measurement and discloses a hand-held device for measuring the lodging-resistant strength of a crop, comprising a clamping unit and a shell, wherein the clamping unit is provided with an adjustable opening used for clamping a crop stalk to be measured; the shell is connected with the clamping unit and comprises a measuring unit, the measuring unit comprises a cantilever beam sensor, an inclination angle sensor, a processing unit and a display unit, wherein the cantilever beam sensor is fixed with the clamping unit and is used for measuring the value of a thrust transmitted by the clamping unit and applied to the stalk to be measured in real time, converting the value of the thrust to electric signals and transmitting the electric signals; the inclination angle sensor is horizontally fixed at the bottom of the shell and is used for measuring the inclination angle value of the shell relative to the horizontal plane in real time, convertingthe inclination angle value to the electric signals and transmitting the electric signals; the processing unit is used for receiving the electric signal transmitted by the measuring unit in real timeand converting the electric signals to the corresponding measurement values, storing the required measurement value according to the measuring target set by a user and outputting the required measurement value; and the display unit is used for displaying information outputted by the processing unit. By adopting an undamaged measurement method, the device can be widely applied to breeding processes or crop producing management.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a device for measuring lodging resistance of crops and a method for using the device for measurement. Background technique [0002] Lodging is a phenomenon in which plant stems change from a natural upright state to a permanent dislocation caused by external factors. It is common in crop production, especially in cereal crops, and has become one of the main limiting factors for high and stable yields. In various studies and standards, there are many divisions of lodging degrees. The national rice lodging standard is divided into four levels: straight, oblique, inverted, and volt. Among them, straight: the stalk is upright or basically upright; oblique: the inclination angle of the stalk is less than 45 degrees; inverted: the inclination angle of the stalk is greater than 45 degrees; : The stems and ears are completely attached to the ground. Zhang Zhongxu et al. proposed i...
