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

specific Embodiment approach

[0018] refer to figure 1 , lawn grass texture and color measuring ruler, comprising measuring device 1, texture scoring device 2, color and luster scoring device 3, said measuring device 1 is a ruler with precise scale, and said texture scoring device 2 is for scoring points And the curved ruler of the curved ruler that is the radial scale mark, the scale line of described measuring device 1 and described texture scoring device 2 has common endpoint, and this endpoint is the zero point of measuring device 1, the scoring of texture scoring device 2 The score scale begins at this endpoint and is distributed radially, close to the edge of the high division to coincide with the zero scale line of the measuring device. The color scoring device 3 includes a transparent observation window and a grass color standard gradient block 4 arranged at the bottom of the transparent observation window. Quantitative marks are correspondingly marked beside the grass color standard gradient bloc...

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, colorgrading 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...
