Problems solved by technology

In the actual work of agricultural scientific research, due to the differences in varieties or experimental schemes, the sampling amount of leaf area is extremely large. The traditional grid cross method, copy weighing method, scanner method, regression equation method and other measurement methods are time-consuming. Most of the portable leaf area measuring instruments are manually operated on a single leaf, which is not efficient and cannot meet the needs of scientific research

Abstract

The invention relates to an automatic plant leaf area measuring instrument which comprises a machine base, a large pressing block and a small pressing block, guide columns are arranged on the outer sides of the large pressing block and the small pressing block, the large pressing block and the small pressing block are installed on the machine base by being inserted into guide grooves of the machine base, a motor is installed on the machine base, a driving gear is installed on a shaft of the motor, and two transmission gears are installed beside the driving gear. The two transmission gears are meshed with a leaf feeding driving roller gear and a leaf discharging driving roller gear respectively, the leaf feeding driving roller gear is installed on a shaft of a leaf feeding driving roller, the leaf discharging driving roller gear is installed on a shaft of a leaf discharging driving roller, a coding disc is installed on a shaft at the other end of the leaf feeding driving roller, and the coding disc is installed on a shaft at the other end of the leaf discharging driving roller. A grating sensor is installed below the coding disc, a CCD sensor is installed between the leaf inlet driving roller and the leaf outlet driving roller, a leaf inlet driven roller and a reflector are installed at the bottom end of the large pressing block, and a leaf outlet driven roller is installed at the bottom end of the small pressing block.

Description

technical field [0001] The invention belongs to the technical field of plant measurement, and in particular relates to an automatic measuring instrument for plant leaf area. Background technique [0002] Leaf area is an important index in crop cultivation physiology and breeding research, and the total leaf area is also an evaluation index for crop yield and quality. In the actual work of agricultural scientific research, due to the differences in varieties or experimental schemes, the sampling amount of leaf area is extremely large. The traditional grid cross method, copy weighing method, scanner method, regression equation method and other measurement methods are time-consuming. Most of the portable leaf area measuring instruments are manually operated on a single leaf, which is not efficient and cannot meet the needs of scientific research. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides...
