Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pasture seed detection, and specifically relates to a culture device for coated pasture seed germination rate detection. BACKGROUND

[0002] Coating of pasture seed is a modern seed treatment technology, which significantly improves the growth efficiency, stress resistance and sowing convenience of pasture seed by wrapping a layer or multiple layers of functional material on the surface of pasture seed. Before sowing of pasture seed, it is necessary to analyze the pasture seed, and observation and measurement of the germination rate and germination potential of coated pasture seed are one of the important means of analysis, which can lay a foundation for judging the emergence rate of pasture. The process mainly includes randomly selecting 100 coated pasture seeds, arranging them on the moisture paper of a culture dish, observing and recording the situation every day, then counting the number of normally germinated pasture seeds within a specified date, and calculating the germination number of coated pasture seed, and then obtaining the germination rate. Since the pasture seed is very small, 100 coated pasture seeds are placed in the culture dish, and the previously arranged pasture seeds are easily scattered when the culture solution or water is added, which makes the pasture seeds disordered and is not conducive to the subsequent germination rate statistics.

[0003] At present, it is relatively cumbersome to place 100 coated pasture seeds in each culture dish, and it is necessary to manually place each seed in the culture dish with tweezers or other tools, or a seed planting device is needed to plant the built-in seeds one by one on the culture dish. Such operation not only wastes time and effort, but also needs manual control of the uniformity of the distance between the seeds during the seed distribution process, and it is easy to have a large error. It takes 100 times to repeat the steps to plant 100 seeds, which is a considerable waste of manpower and time. UTILITY MODEL CONTENT
