Core Viewpoint - The article emphasizes the importance of a comprehensive green storage system for grain, which integrates intelligent monitoring, physical and biological control, and minimized use of chemical agents to prevent grain pests and ensure food quality [1][4]. Summary by Sections Green Storage Techniques - Green storage does not completely eliminate chemical agents but focuses on a "prevention first, integrated control" approach to form a collaborative ecological grain storage system [1][4]. - The annual loss of grain during storage in China exceeds 200 billion jin, with over half attributed to storage pests [1]. Low-Temperature and Low-Oxygen Environments - Creating low-temperature environments in grain storage can suppress pest activity and microbial growth, with temperatures below 15°C causing pests to enter dormancy or die [2]. - Technologies such as internal circulation temperature control and nitrogen gas storage are employed to maintain low temperatures and low oxygen levels, effectively killing pests without chemical residues [2]. Biological Control Methods - Establishing a micro-ecosystem in storage facilities can help control pests through biological means, such as introducing natural enemies like parasitic wasps and using targeted microbial agents [3]. - Despite challenges in large-scale application, biological control methods have shown promising results in specific ecological zones and may complement chemical methods in the future [3]. Digital Monitoring and Data Analysis - Transitioning from passive to active pest control involves utilizing advanced intelligent monitoring systems that integrate various data sources to predict pest outbreaks and trigger preventive measures [3]. - Technologies such as distributed traps and high-spectral cameras are used to collect real-time data on pest activity, enabling targeted interventions [3].

Core Viewpoint - The article highlights the construction of China's first batch of five 9,000-ton gas membrane grain silos, which represent the fourth generation of new grain storage technology, emphasizing their advanced features and benefits for grain preservation [1][2]. Group 1: New Grain Silos Features - The gas membrane silos are 33 meters tall and have a diameter of 24 meters, each capable of storing approximately 9,000 tons of grain [1]. - The silos feature a unique multi-layer structure that includes a waterproof PVDF membrane, an insulation layer made of polyurethane, and a supporting structure of reinforced concrete, enhancing their airtightness and thermal insulation [2][4]. - The gas membrane silos have an airtightness performance that exceeds national high standards by more than six times and thermal insulation performance that is over three times better than traditional silos [2]. Group 2: Importance of Airtightness and Insulation - Airtightness and thermal insulation are crucial for grain storage as grains respire, consuming oxygen and releasing carbon dioxide, which can lead to nutrient loss if not properly managed [2][3]. - In high-temperature and high-humidity conditions, improper storage can significantly degrade grain quality over time [3]. Group 3: Cost and Safety Considerations - The initial construction cost of gas membrane silos is comparable to traditional silos, but they offer faster construction times, saving on time costs [4]. - The silos have passed fire safety audits due to the incorporation of flame-retardant materials, ensuring safety during operation [4]. - The five gas membrane silos are expected to be completed by the end of the year, adding a total storage capacity of 45,000 tons to the grain reserve [4].
