Crop root system length measuring device based on biological characteristic simulation

Abstract

The invention discloses a crop root system length measuring device based on biological characteristic simulation. The device comprises a culture cylinder, a cylinder cover and a root system traction device, wherein the cylinder cover is arranged at the top of the culture cylinder, a closed cavity is formed between the cylinder cover and the culture cylinder, and an annular pipe distributed along the circumference of the cylinder cover is fixedly arranged on an inner wall of the cylinder cover; an electromagnetic valve I and an electromagnetic valve II which are communicated with the annular pipe are arranged on the outer wall of the cylinder cover, the other end of the electromagnetic valve I is connected with an exhaust fan, the other end of the electromagnetic valve II is connected with an air storage tank, a carbon dioxide concentration detector is arranged on the outer side wall of the cylinder cover, and a shading device located below the incandescent lamp tube is arranged on the outer side wall of the cylinder cover. The device is advantaged in that the structure is compact, root system measurement precision is improved, the growth lengths of different crop root systems under the conditions of nutrient solutions with different concentrations, different illumination areas, different illumination intensities and different carbon dioxide contents can be intuitively measured, and operation is simple.

Description

Technical field [0001] The present invention relates to the technical field of measuring the length of the root length in analog environments, in particular, a crop root length measuring device based on biological characteristics simulation. Background technique [0002] Gramtropgraduate crops include corn, sorghum, wheat, rice, etc., the growth of gramic crops determine the future production of farmers. In different climate, different geographic conditions of agricultural planting bases, farmers need to measure the growth of gram undergraduate crops in the growth process, and measurement parameters mainly include straw height, root length, blade length, blade width, etc. The length measurement is one of the important parameters. [0003] In the CN209246871U, China Patent Publication No. CN209246871 is disclosed, and a device for measuring the length of the hydroponic and fog plant, including a laterally disposed supplying tube, which is provided in the longitudinal directional i...

AI Technical Summary

Problems solved by technology

[0004] Though this device and existing root system measuring device can measure the length of the root system of the gramineous crops in the growth process, the following defects still exist: 1, artificial reading value on the test tube is inaccurate, which reduces the measurement accuracy of the root system

II. It is impossible to intuitively measure the root growth length of the root system of different gramineous crops under the conditions of different concentrations of nutrient solution, different light area conditions, different light intensity conditions, and different carbon dioxide content conditions, and then it is impossible to study the growth of gramineous crops. best planting area

III. The test tube cannot stably fix grass crops

IV. The root system of gramineous crops is suspended in the nutrient solution, and the root system is likely to grow along the horizontal direction, resulting in inaccurate root length readings, which further reduces the measurement accuracy of the root system
