Description

Technical Field

[0001] This utility model relates to the technical field of field testing equipment for maize breeding, and in particular to a trait observation device for testing maize varieties. Background Technology

[0002] In the multi-site testing and evaluation of commercial maize breeding, it is necessary to establish a large number of standardized testing sites in various ecological zones to uniformly measure plant height, ear height, ear length, and number of rows per ear of experimental maize, and to determine and record the severity of diseases such as large leaf spot, gray leaf spot, stalk rot, ear rot, and head smut on-site. Existing field observation methods have the following shortcomings: The tools are scattered and the operation is cumbersome: Plant height is measured separately using a measuring tape or a dedicated height measuring rod; ears of fruit are measured separately using a ruler or a seed testing board; and disease status is recorded manually with pen and paper. Multiple tools need to be carried in the field, and changing them back and forth is cumbersome, resulting in long observation times at single points. Measurement standards are inconsistent: Different observers have different methods for placing and reading the measuring tape; manual estimation of ear rows and disease severity has significant subjective errors; and data from multiple testing points lacks standardized specifications. Functional modules are isolated: Existing integrated products only integrate plant height and ear position measurement with data recording; there is a lack of technical solutions that organically integrate the three major functional modules of plant height and ear position measurement, ear trait measurement, and disease severity labeling into a single device, and there is a lack of structural synergy and linkage between the modules. Data is easily lost: Paper records are frequently damaged by moisture, wear, and transcription errors, resulting in a large workload for subsequent data entry.

[0003] To address the aforementioned issues, there is an urgent need for trait observation devices for maize variety testing to improve the efficiency and standardization of field data collection. Utility Model Content

[0009] Optionally, the telescopic scale of the telescopic plant height and ear height measurement module and the reference baffle of the ear trait rapid recording module are both installed and fixed with the guide rail as the common positioning reference surface.

[0010] Optionally, the detachable disease resistance rating component includes five identification slots for disease grades 0 to 9 and a marking slider that slides on each identification slot. The five identification slots are for five types of diseases: large leaf spot, gray leaf spot, stem rot, ear rot, and head smut. The marking slider corresponds to the grade 0 to 9 for each type of disease. Each identification slot is equipped with a micro switch at its end, which is electrically connected to the data storage and transmission module.

[0011] Optionally, the data storage and transmission module receives measurement data from each module in real time and displays disease level signals triggered by microswitches on the screen. It also automatically associates and stores plant height, ear height, ear length, number of ear rows, and various disease levels under the same strain number. All observation data are classified and stored according to test point number and strain number, and can be exported to Excel spreadsheets through the data export interface.

[0012] Optionally, the handheld unit has a non-slip rubber grip on the side and a built-in rechargeable lithium battery at the bottom.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The guide rail allows plant height measurement and ear measurement to share the same spatial coordinate reference, eliminating cumulative errors caused by multiple positioning and improving the consistency of multi-point test data. The micro-switch at the end of the disease grading slot realizes a complete chain of slider sliding, electrical signal triggering, and automatic data association, avoiding manual transcription errors and ensuring accurate association between disease grades and corresponding varieties and trait data. The machine is lightweight, integrating all functions of plant height and ear position measurement, ear trait measurement, and disease grade labeling into one device, making it suitable for mobile field operations at dispersed and long-distance test points. The disease labeling component is snap-on and can be replaced with the label panel according to the key monitored diseases of the year, adapting to the testing needs of different years and different ecological zones.
