Texture and color measuring ruler for lawn grass

Abstract

The invention relates to a lawn grass quality and color scale, comprising a measuring device, a quality grading device and a color grading device. The measuring device and quality grading device have a same endpoint that is a zero point of the measuring device. The grading value graduation mark of the quality grading device is in radial pattern from the endpoint, and the range is between 0 and 9; the color grading device comprises a transparent observation window and a grass color standard gradient block installed at the bottom of the transparent observation window, and quantitative mark is correspondingly marked near the grass color standard gradient block. In the invention, internationally common nine-level grading method is solidified in the scale, and the width, quality grading, color grading of lawn grass can be simultaneously read out by one-time measurement; the operation is simple and visual, and the grading results are objective and are not influenced by the technical level and subjective factors of the measurers, thereby having high precision and good repeatability.

Description

technical field [0001] The invention belongs to measuring instruments, in particular to an instrument for measuring and scoring lawn grass blade width, texture and color. Background technique [0002] In recent years, my country's lawn industry has developed rapidly. It is common to evaluate lawn texture, color and other indicators. Lawn grass quality refers to the touch and leaf width of lawn grass blades. period and the level of maintenance management. [0003] The traditional lawn texture evaluation method uses leaf width as an index. The wider the leaf, the lower the score, and the finer the leaf, the higher the score, and the better the texture. The general measurement procedure is to first measure the width of the turfgrass blade, and then convert the width data into a nine-grade score value for the texture of the turfgrass blade according to the nine-grade scoring method. The evaluation results cannot be directly obtained, the process is cumbersome, time-consuming an...

AI Technical Summary

Problems solved by technology

Evaluators need to have rich experience and have a deep and accurate understanding of the nine-level grading method for turfgrass color. Ordinary scientific researchers and turfgrass practitioners cannot correctly evaluate turfgrass color due to lack of relevant professional knowledge; Weather conditions, affected by the venue, sunny days with too much light and rainy days with dim light cannot be accurately evaluated and scored, and must be done on the lawn
