Relevant explanations of technical indicators of crop germplasm resources The development of technical indicators of crop germplasm resources is based on the following principles: (1) The main research and breeding needs of crop germplasm resources are taken into account, taking into account both production and market needs. (2) Based on the existing research and work foundation in China, consider future development, and set aside space for expansion. (3) Drawing on international advanced indicators, expanding and innovating on the basis of digestion and absorption. (4) The combination of science, system and practicality. (5) Combination of key technical indicators and method inheritance and innovation. (6) Focus on new technical indicators such as quality (nutritional quality, sensory quality, processing quality, storage freshness, etc.), resistance to pests and diseases, and stress resistance characteristics. (7) Strengthen the development of China's unique resources and specificity technical indicators. Based on the above principles, after summarizing the steps of extraction, testing and development, improvement, testing, technical validation, and peer recognition, technical specifications for 110 crops including food crops, cash crops, vegetables, fruit trees, and forage green manure are presented. 3,824, focusing on new technical indicators such as quality, pest resistance and stress resistance characteristics, integrating and upgrading 1,793 technical indicators, summarizing and improving 9,436 technical indicators, and achieving 15,05 crop germplasm resources technical indicators System specification. In addition, in order to collect and discover the seeds of various crop varieties and scientifically store them so that the germplasm still has original genetic characteristics and high germination power after more than ten years or even decades, we have established crop germplasm resources. The library, which covers different varieties of seeds, is used for variety improvement, breeding of new varieties with high yield, high quality, and strong resistance. According to the different temperature and humidity environments in the library, seed storage buildings can be divided into three categories: long-term storage, which can be stored for up to 30 years; medium-term seed storage, which can be stored for 5 to 15 years, and short-term storage. The library can be stored for 3-5 years. Cabinet Type Air Handling Unit
Cabinet type air handling unit
Face the air intake opening, if the pipe connection and service panel are on the left side, the unit will be considered as left connection, otherwise will be right side.
Characteristics:
1.Air handing unit applies colorful steel and galvanized panel as its interior and exterior panel. Inner stuff is the high density polyurethane foam,double pillar and tenon structure that ensures the strength of the unit and low air leakage.
2.High efficiency and low resistance nylon filter that reduce the power consumption obviously. Easy cleaning and simple operation; at the same time, higher level panel filter is optional too.
3.Coil applies pure and seamless copper tube and hydrophilic aluminum fin. Copper tube is under 12MPa water pressure expanding that can adapt to all kind of high pressure and no leakage, as well as ensure the lowest contact thermal resistance and highest heat transfer efficiency.
4.All fans in the unit are selected by professional software to ensure the best condition. Minimize the air volume and air pressure loose after meeting with the customer's requirements. Also ensure the good airflow and reduce the air duct noise.
5.Cabinet type air handling unit wish small size, low noise. It is widely applied in the comfortable air conditioning system such as the hostel, commercial building, office and underground railway application.
