How to do dry beans

1. The base fertilizer should be sufficient, the proportion of organic fertilizer should be increased appropriately, and the fertile farmyard manure should be applied. The topdressing should be carried out in time during the growth process. The topdressing is generally based on urea, which is reasonably applied according to the growth of the beans.

2. After topdressing, it is necessary to ensure the supply of water, timely watering, and promote the better absorption of the beans with water and fertilizer. In order to ensure the strong growth of the beans, foliar spraying of plant growth agents and foliar fertilizers can be carried out. Mix the liquid with the foliar fertilizer and apply once every half month.

3. During the spraying of pesticides, the leaves of the beans should be washed frequently with water to reduce the pesticide residues, which can effectively avoid the dry leaves of the beans.

Integrated Roughness Profile Measuring Instrument

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:

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.
