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.
With the continuous advancement of social science and technology, coupled with the development of the Internet, the standards for the determination of seed quality have become more stringent. In the current seed inspection, the application of seed cleanliness workbenches has become more widespread. This is also an important trend in the development of the modern seed industry. So before using seed cleanliness workbench for seed inspection, what kind of methods do people use for seed inspection? Here is an example to illustrate, but also from the side to reflect the advantages of seed cleanness table.
