The original species is the basic seed that has been produced by the breeder breeding farm or breeder breeding unit through the original seed production process and is of higher purity, better quality, and can be further used for breeding elite breeds. Developed countries also classify the original species into vegetative and basic seeds. The seeds of the cultivators are the original and non-mixed seeds produced by breeders themselves, so they are also called original species. The basic seeds refer to seeds that were directly propagated from the original seeds and were eliminated through strict control or from the direct control of improved breeder breeding grounds. They are also known as primary seeds. Progeny produced from the seeds of the original species are called test seeds. In the past, we have named them as first-class seedlings and second-class seedlings. In 1989, China's Ministry of Agriculture promulgated the "Approved Measures for Crop Variety", which stipulates: "The species approved for approval shall be provided by breeders to provide a certain number of seeds and seeds for accelerated propagation." The original species referred to here is the beginning of new varieties. The most original high quality seeds produced and promoted.
With low-power, miniature size, the serial communication department range sensor with mm accuracy can measure up to 20m, 40m, 60m, 100m, 150m, 200m.
