With the continuous progress of social science and technology, and the development of the Internet, the criteria for judging the quality of seeds are more accurate and reliable. Seed quality testing instruments such as seed clarity tools are commonly used to test the quality of seeds. This is a major trend in the development of the modern seed industry.

In the past, we mainly achieved the test of seed quality through vision, smell, touch, and hearing.

1. Use the eyes to judge the seed quality, such as the number of seeds, the color is normal, there is no pest, bacillary dysentery or mildew.

2. Use the nose to determine whether the seed has become rotten, spoiled, or smells. Use the nose to determine whether the seed has become rotten, spoiled, or smells. For example, the seeds that have sprouted are sweet, and the seeds that are moldy have a sour or alcoholic taste.

3. Using the touch feel, mainly for the traditional Chinese herbal seed moisture break. If the hand is inserted into the seed bag, it feels loose, smooth, has little resistance, has audible noise, and when the seeds are grasped by hand, the seed easily flows out of the hand and the moisture is small.

4. In addition, there are auditory judgments on the quality of seeds, grasp a handful of Chinese herbal medicine seeds hold tight, five-finger activity, listening to the sound of rustling, with the peel of the species to shake or raise the sound of hearing, the greater the general sound, The less water content.

These are methods that have been summarized in long-term farming in the past when technology was underdeveloped. They have been widely adopted for a long time, but they are also flawed. They can perform preliminary inspections on seeds but do not achieve quantitative quantification of seeds. Testing, and the use of instruments such as seed cleanliness workbenches, can be abstracted as concrete, allowing seed inspection work to become more clear and accurate.
