Protective goggles selection guide
A laser filter that blocks a specific wavelength of laser light becomes safer to the eye as the transmittance becomes zero.
Optical density (OD value) expresses the degree of absorption as a logarithm.
The higher the optical density (OD value), the higher the safety.
For example, if a CW 1kW laser beam is transmitted through laser protective glasses with an OD value of 6, it will be 1mW.
Indicates the transmittance of visible light.

Potato industry seeks development and cooperation
[ China Agricultural Machinery Industry News ] As the main force for the increase of grain crops in China in the future, potatoes have great potential in increasing yields, extending the industrial chain and increasing farmers' income. At present, the industrialization of potato staple food in China has entered a stage of rapid development, but the problems in the top design of industrial development have become increasingly prominent.
Chen Mengshan, party secretary of the Chinese Academy of Agricultural Sciences and deputy head of the National Agricultural Science and Technology Innovation Alliance leading group, pointed out at the inaugural meeting of the National Potato Industry Technology Innovation Alliance that the top design must be done in a "national organization, national research" manner. , solidly promote the future development of the potato industry.
Potato industry seeks development and cooperation
The National Potato Industry Science and Technology Innovation Alliance is led by the Vegetable and Flower Institute of the Chinese Academy of Agricultural Sciences. It is jointly established by the United Nations, provincial, prefecture-level agricultural research institutes, agriculture-related universities and related enterprises.
Key elements are not yet available
China is a big potato producer. Regarding the development of the potato industry, Chen Mengshan has two judgments: First, the current potato planting area is less than 100 million mu, and the crops that can increase the area of ​​China's food crops for a long time in the future are mainly potatoes. Second, the current industrialization of potato staple food has entered a stage of rapid development. Of the 391 poverty-stricken counties in the country, 70% are the main potato producing areas. Moreover, the potato has a large potential for yield increase, a long processing industry chain, and a large potential for income generation.
However, the current development of the potato industry still faces many challenges.
Li Shun, chairman of Beidahuang Potato Group Co., Ltd., believes that the potato industry is facing a severe situation of reform. Compared with other foods, the industrial policy of potatoes is not complete. At the national level, since the reform and opening up, the industrial policies and regulations and standard systems of potatoes have not been sound enough. The requirements for further expansion and development of the industry are not suitable, the direction of industrial development is not clear enough, and the policy of industrial development is not perfect.
Sun Rifei, director of the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences and the chairman of the alliance, pointed out that some major scientific propositions facing potato production have not been solved in time. For example, the varieties of precocious, high-yield, resistant and staple food products are lacking; the quality control system of seed potatoes is still not perfect, and the prevalence of detoxified seed potatoes is low; the cultivation techniques, especially those based on agricultural machinery, are still not Supporting; the main pest and disease green prevention and control technology demand is urgent; the storage technology, process, equipment is relatively backward and the loss during storage is more serious; the main food product processing technology is still relatively late.
Chen Mengshan said: "Now the connection between scientific research and production, scientific research and enterprises is not tight enough. The connection between the innovation chain, the industrial chain and the capital chain is not close enough. The relevant elements of the potato are not yet complete enough, and they are not enough. Only these solutions have been solved. The problem can create conditions for the steady improvement of the potato industry."
Forming scientific research synergy
Chen Mengshan believes that China's scientific research in the field of potato-related areas is not enough. "The alliance can make the potato scientific research form a whole force, and through the national organization, form a national keystroke. This is a way of quick effect and mechanism innovation."
To this end, Chen Mengshan pointed out the direction of scientific research that needs to be tackled for the newly established Industrial Innovation Alliance. The first is variety innovation, that is, direct research on basic biology of biology and genetics. At the same time, it is necessary to improve the quality control level of seed potatoes, promote the popularization and application of detoxification seed potatoes, study the quality detection technology and traceability technology of seed potatoes, and establish a sound quality control system for potato virus-free seed potatoes.
“It is also necessary to strengthen the integration research of green high-yield technology.†Chen Mengshan believes that a series of research and promotion of soil improvement and fertilization, water and drought resistance, scientific fertilization, water and fertilizer integration, etc. should be integrated according to suitable varieties and ecological conditions in different main producing areas. Advanced cultivation techniques. “The key here is machinery, agricultural machinery and agronomic equipment. All technologies must be based on agricultural machinery, and the technology is attached to the agricultural machinery to improve the level of mechanization and automation.â€
In addition, it is necessary to improve the storage method of potatoes, attach great importance to the screening and improvement of special varieties of potato staple processing, and cultivate and form the Potato Alliance think tank to provide necessary consulting services for industrial development.
Explore collaborative innovation mechanisms
"It’s not to fall into a certain scientist, but to mobilize everyone’s enthusiasm and to unite the strengths of various departments, regions, and professions. This is the first thing that the Innovation Alliance must do.†Chen Mengshan believes that The top-level design is to do an innovation alliance and design the whole around an industry issue.
Through the Chinese Academy of Agricultural Sciences to take the lead in forming a collaborative innovation pattern of the national chess game, the research will drive the scientific research tasks of scientific research units and universities around the country, and through the topic, everyone will come together to form a “big chorusâ€.
Chen Mengshan also suggested that the work mechanism should be innovative, including learning exchange mechanism, evaluation mechanism, coordination mechanism, and sharing mechanism. Through the mechanism to collect national resources, local resources, human capital, etc., truly focus on the "big article" of the potato, the implementation of collaborative innovation, collaborative research.
Wan Jianmin, vice president of the Chinese Academy of Agricultural Sciences, also pointed out that the National Potato Industry Science and Technology Innovation Alliance should explore the establishment of a collaborative innovation mechanism that is conducive to the development of the alliance, such as government support, task traction, resource sharing, incentive evaluation, etc., and increase funding, conditions, personnel training, etc. Support in terms of aspects. In the creation of development conditions, we will strive for strong support from all parties, give full play to the role of corporate investment, broaden the funding channels of the alliance, and allow enterprises and other social forces to benefit from the construction of the alliance.
