The seed shape and size observation instrument and the observation method are used to solve the problem of poor measurement accuracy when observing the length and width of seeds with bare hands. It includes a base, a stage, a clamping assembly, a scale plate and an enlargement assembly. There is a vertical rod on the top of the base, a stage under the vertical rod, and a chute on the top of the stage. A slide plate is slidably installed in the chute, a lead screw nut is arranged at the bottom of the slide plate, and a lead screw matched with the lead screw nut is arranged on the stage. A clamping assembly for clamping grains is provided on the slide plate; first and second laser lamps are provided on the clamping assembly, and the first and second laser lamps can emit beams of different colors; There is a scale plate, and there is a mesh scale line on the surface of the scale plate; above the scale plate, there is a magnification assembly, which includes a cross bar, a mounting block, a lens and a dust cover, and the scale plate is observed through the magnification assembly. readings. The invention can realize the measurement of the length and width of the seed grains, and has good measurement precision and high working efficiency.
Description
technical field [0001] The invention relates to the technical field of seed grain size measurement, in particular to a seed shape size observer and an observation method for conveniently measuring the grain length and width of the grain. Background technique [0002] The shape and size of the seed grain is an important index to evaluate the quality level of the seed. It is not only related to the thousand-grain weight, germination ability and stress resistance characteristics of the seed, but also directly affects the survival ability of the seedling and the yield of the crop. Therefore, screening seeds with good grain shape and high quality is a prerequisite for improving seed storage life, germination efficiency and ensuring neat emergence. Due to the rich variety and various shapes of crop seeds, the shape observation of seeds is not only time-consuming, laborious, and difficult to accurately distinguish, but there is still a lack of effective equipment for measuring and ...
