First of all, we must ensure that the varieties are selected correctly, such as suitable for open field cultivation, greenhouse cultivation, plastic arch shed cultivation, plastic film mulching cultivation, etc.; suitable for early maturing cultivation, medium ripening cultivation, delayed cultivation; suitable for cultivation in different regions. If you have introduced varieties that have not been planted in this area, you must try a small area and plant them in large areas. At the same time, we must also pay attention to the requirements of local consumption habits. Next, it is best to test the germination potential and germination rate of the purchased seeds before sowing. The simple germination potential calculation is the percentage of seed germination within 3 days of cucumber germination. Seeds with strong germination are quick and tidy. The germination rate is the percentage of germinated seeds in a certain amount of seeds. Cucumber generally refers to the percentage of germination of seeds within 7 days of germination. When the germination rate is above 90%, the seeding requirements can be met. Disclaimer: Some articles on this website are transferred from the Internet.

Roughness meter, also known as surface roughness meter, surface smoothness meter, surface roughness tester, roughness measurement meter, roughness tester, and other names. It has the characteristics of high measurement accuracy, wide measurement range, easy operation, portability, and stable operation. It can be widely used for the detection of various metal and non-metal processing surfaces. This instrument is a pocket instrument that integrates sensors and hosts, with handheld characteristics, making it more suitable for use in production sites. The exterior design is sturdy and durable, with significant resistance to electromagnetic interference, in line with current design trends.
The application fields of roughness meters include: Integrated Roughness Profile Measuring Instrument,High Speed Profilometer,Profilometer Measurement,Surface Profilometer Zhejiang dexun instrument technology co., ltd , https://www.dexunmeasuring.com
1. Mechanical processing and manufacturing industry, mainly metal processing and manufacturing. Roughness meters were originally developed to detect the surface roughness of machined parts. Especially, stylus type roughness measuring instruments are more suitable for detecting hard metal surfaces. For example, the automotive parts processing and manufacturing industry, the mechanical parts processing and manufacturing industry, and so on. As long as these processing and manufacturing industries involve the surface quality of workpieces, the detection application of roughness meters is essential.
2. In the non-metallic processing and manufacturing industry, with the progress and development of technology, more and more new materials are applied to processing processes, such as ceramics, plastics, polyethylene, etc. Some bearings are now made of special ceramic materials, and pump valves are made of polyethylene materials. These materials have a hard texture, and some applications can replace metal materials to make workpieces. During production and processing, their surface roughness also needs to be tested.
3. With the continuous strengthening and improvement of the technology and functions of roughness meters, as well as their in-depth promotion and application, more and more industries have been found to require roughness detection. In addition to mechanical processing and manufacturing, roughness evaluation is also required in the production and processing of power, communication, electronics, such as couplings on switches, integrated circuit semiconductors, and even stationery, tableware, and other products used in people's daily lives The surface roughness of human teeth needs to be tested.
