Biomass living body detection device and method based on moment

Abstract

The invention discloses a biomass living body detection device based on a moment, comprising a sensor module, a support module and a data collecting and analyzing module, wherein the sensor module comprises a moment sensor for acquiring the rebounding property of a crop to be measured when the core is subject to external force; the sensor module is positioned on the support module for supporting the sensor module; and the data collecting and analyzing module is connected with the sensor module and is used for obtaining the biomass of the crop to be measured according to the rebounding property acquired by the sensor module. Compared with a disc-dropping type tester, the crop biomass living body detection device based on a moment provided in the invention can carry out continuous measurement, and compared with a swing type biomass tester, the biomass living body detection device based on a moment without swinging components and requirements on the constant-speed movement of a mounting platform has the advantages of portability and accurate and reliable measuring result and is especially suitable for measuring the biomasses of the crops in patches in a breeding process.

Description

technical field [0001] The invention relates to the technical field of crop biomass measurement, in particular to a torque-based living biomass detection device and method. Background technique [0002] Among the agronomic parameters observed in the field of crops, biomass is an important indicator reflecting the growth status of crops. Biomass refers to the total amount of living organic matter per unit area at a certain time. In the narrow sense, biomass only refers to weight, which can be fresh weight or dry weight. Biomass is an important indicator that reflects the growth status of crops, and is related to the stress resistance and disease resistance of plants. In general, the greater the biomass, the greater the yield. Therefore, rapid detection of biomass in the process of crop breeding is of great significance for screening germplasm resources and optimizing varieties. [0003] The traditional method for measuring the biomass of crops is to measure the dry weight ...

Problems solved by technology

The drop-disk measuring instrument can only measure at a single point. For the plot with uneven plants, the error can only be minimized by taking the average value of multi-point measurement, and it is difficult to continuously measure the crops in the field.

[0008] Germany's biomass analyzer based on the principle of angle measurement uses a tractor as a platform, and the data acquisition part is realized by a computer placed in the cab, and the traveling speed is very fast, so it is only suitable for field measurement, such as a crop growth sensor in precision fertilization use, it is difficult to meet the requirements of small population biomass measurement in the breeding process

The pendulum biomass analyzer uses the pendulum as a swinging part. Due to the unevenness of the ground, the tractor will undulate, which will easily cause the pendulum to vibrate, resulting in measurement noise and affecting the accuracy of the measurement results.

In addition, the pendulum biomass analyzer requires the tractor to move at a constant speed, and the unevenness of the speed has a great influence on the measurement results.
