A device for measuring root system length of crops based on biological characteristics simulation

Abstract

The invention discloses a crop root system length measuring device based on biological characteristic simulation, which comprises a cultivation cylinder, a cylinder cover and a root traction device, the cylinder cover is arranged on the top of the cultivation cylinder, and an airtight cavity is formed between the cylinder cover and the cultivation cylinder. The inner wall of the cylinder cover is fixed with an annular pipe distributed along its circumference, and the outer wall of the cylinder cover is provided with a solenoid valve I and a solenoid valve II connected with the annular pipe. The other end of the solenoid valve I is connected with an exhaust fan, and the solenoid valve The other end of the II is connected to an air storage tank, a carbon dioxide concentration detector is arranged on the outer wall of the cylinder cover, and a light-shielding device located under the incandescent tube is arranged on the outer wall of the cylinder cover. The beneficial effects of the present invention are: compact structure, improved root system measurement accuracy, and intuitive measurement of root system growth of different crops under conditions of different concentrations of nutrient solution, different illumination area conditions, different illumination intensity conditions, and different carbon dioxide content conditions Length, easy to operate.

Description

technical field [0001] The invention relates to the technical field of measuring the length of the root system of crops in a simulated environment, in particular to a device for measuring the length of the root system of crops based on biological characteristic simulation. Background technique [0002] Grass crops include corn, sorghum, wheat, rice, etc. The growth of grass crops determines the future output of farmers. In agricultural planting bases in different climate regions and different geographical conditions, farmers need to measure the growth of gramineous crops during the growth process. The measurement parameters mainly include straw height, root length, leaf length, leaf width, etc., among which the root system The measurement of length is one of the important parameters. [0003] Chinese Patent Publication No. CN209246871U discloses a device for measuring the root length of hydroponic and aeroponic plants, including horizontally arranged liquid supply pipes, an...

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
