Plant blade area measuring apparatus

Abstract

The present invention relates to a plant leaf area measuring apparatus that is applicable to the agricultural scientific research, and comprises an upper transmission pressing belt, a lower transmission belt, a micro reducing motor, a camera, an image reflector, a rear-end reflector, an illuminating light source, a signal transmitting shaft and a reflection membrane belt that is winded on the signal transmitting shaft, wherein, the camera, the image reflector, the illuminating light source and the signal transmitting shaft are arranged on the lower transmission belt that is positioned into a ring shape through a transmission positioning shaft unit. The measuring apparatus has the advantages of high analysis efficiency, precision, simple structure, low cost, etc. and can realize the technical effect that the measurement result value is obtained through the continuous leaves transmission, continuous measurement, calculation and accumulation.

Description

technical field [0001] The invention relates to a measuring instrument suitable for agricultural scientific research, in particular to a plant leaf area measuring instrument. Background technique [0002] The measurement of plant leaf area is widely used in agricultural scientific research. Plant leaves produce nutrients through photosynthesis to make plants grow continuously and form yields. When the plant photosynthetic rate and light exposure time are constant, the size of the leaf area directly affects the plant photosynthetic products. directly affects crop yield. At home and abroad, the research on the characteristics of plant leaves is very important, and the measurement of its area is the basis of the work in the study of the characteristics of leaves. Traditional leaf area measurement methods include: counting grid method, cutting leaf shape paper weighing method, etc. These methods are relatively backward, and have the disadvantages of labor-intensive, time-consum...

AI Technical Summary

Problems solved by technology

Traditional leaf area measurement methods include: counting grid method, cutting leaf shape paper weighing method, etc. These methods are relatively backward, and have the disadvantages of labor-intensive, time-consuming and large errors

At present, there are various types of measuring instruments for plant leaf analysis in foreign countries. Their complex structures and expensive prices are difficult for ordinary agricultural scientific research units to bear.

So far, there is no low-cost leaf area measuring instrument that can continuously measure, calculate and accumulate the measurement results of multiple strip leaves.
