Seeds are the origin of life, and many plant life begins with seeds. In agricultural production, the importance of seeds is self-evident. As a living individual, seed germination is highly correlated with its own viability. In the sowing stage, it is necessary to ensure that the seeds after sowing can germinate normally, and the seedlings after germination have strong resistance and healthy growth. Seed sowing with high germination rate is the most effective way, so how is the germination rate of the seeds tested? Come out? It is common to use a precision seed germination box to create seed germination conditions, perform seed germination culture experiments, and then count and calculate. Seed germination is the beginning of the life of the seed plant, and the radicle breaks through the seed coat to germinate. Seed germination requires certain conditions to support. From its own point of view, only living seeds can germinate. Some do not germinate seeds because there is no viability, seed empty (no embryo) or embryo damage. From the external conditions, the seed germination also needs to meet the appropriate moisture and temperature conditions, which means that the germination conditions are suitable. While planting under the same environmental conditions, some seeds germinate quickly, while some seeds germinate slowly or not, usually related to the germination ability of the seeds. Therefore, in the seed quality test, one of the objects to be investigated is the seed germination rate. This experiment requires the use of a precision seed germination box. It has been said that the factors affecting seed germination have their own causes and external causes, and the use of precision seed germination boxes can create ideal germination conditions for different seed germination, thus avoiding the influence of external environment on seed germination, and thus accurately and objectively Investigate the germination ability of the seeds. In addition, the ideal germination condition accelerates the germination rate of the seed. Therefore, the use of the precision seed germination box can also improve the efficiency of the seed germination rate test, and is a reliable device for efficiently and accurately testing the germination rate of the seed. Currently, the device is widely used. In the fields of seedling, research and production. Using laser engraving and cutting, the process is as simple as printing on paper using a computer and printer. You can use a variety of graphics processing software, such as CorelDraw, in Win98/Win2000/WinXP environment. Scanned graphics, vectorized graphics and various CAD files can be easily "printed" into the Engraving Machine. The only difference is that printing applies toner to the paper, while laser engraving shoots the laser onto almost all materials such as wood, acrylic, plastic, metal, and stone.

Laser engraving can be divided into dot matrix engraving and vector cutting according to different engraving methods: dot matrix engraving Dot matrix engraving resembles high definition dot matrix printing. The laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head simultaneously moves up and down to engrave a plurality of lines, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be carved using dot matrix. Vector cutting Unlike dot matrix engraving, vector cutting is performed on the outer contour of the graphic. We usually use this mode to perform penetrating cuts on wood, acrylic, paper, etc., as well as marking on a variety of materials.
