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].
粮食减损过硬“新招”让颗粒归仓有保障 科技赋能夯实粮食安全

央视网消息:5月27日,全国粮食和物资储备科技活动周在湖南长沙启动。国家粮食和物资储备局发布10项粮食流通科技创新成果,引导行业 科技力量协同发力,确保国家粮食安全。 这10项成果涉及粮食仓储、粮油食品加工等多个领域。其中,粮仓智慧绿色储粮技术体系创新,主要是利用人工智能技术,创新储粮数量高精 度监测、储粮物联追溯技术,提高储粮管理水平。 粮食减损出新招 小麦"即收即烘"不过夜 粮食收购智能扦检系统已在湖南益阳应用,实现了稻谷、玉米等粮食收购、出库环节自动扦样和22项质量指标无人化检验。 下午2时到傍晚是农民送粮的高峰期,几乎每10分钟就有新收获的小麦送到烘干中心。对于农民来说,麦子收购有标准,水分是一个"硬杠 杠"。多一些水分,直接影响收购价格,进而影响收入,马虎不得。 据了解,当地不少农民对于产后节粮减损、烘干进仓服务都有需求。 "十四五"期间,我国持续加强绿色储粮技术创新系统集成,推广应用绿色储粮技术,全国实现低温、准低温储粮仓容超2亿吨,应用气调储粮 技术仓容超5500万吨。 在四川,小麦从田间收割到烘干入库实现"不过夜",科技赋能让"颗粒归仓"更有保障。 后端烘干能力的加强,让小麦机收更加顺畅。在麦 ...
科技赋能大国粮仓 储粮守护舌尖幸福 探访我国首批5座9000吨级气膜粮仓(在现场)

粮仓内部无梁无柱,几缕阳光从穹顶最高处的圆形孔洞射入,混凝土喷浆机正在进行内壁的施工。王耀 武说,建成后,粮食将通过输送装置从顶部的圆洞进入粮仓,可以实现全程自动化,粮堆内分布的传感 器可以实现对粮食温度等信息的实时监控。 项目建设施工方、中煤建设集团第六十八公司气膜粮仓项目负责人金峰介绍,相比传统粮仓,气膜粮仓 最大的技术特色就是它特殊的多层结构。 防水层的白色PVDF膜材,不仅能反射热量,还有很好的防水性能。里面的保温层,主要由聚氨酯材料 制成,导热系数远低于混凝土建材。而起主要支撑作用的则是内部的结构层,由钢筋混凝土打造。 手中有粮,心中不慌。初夏时节,记者走进中央储备粮长沙直属库,只见方方正正的高大平房仓、圆柱 体形状的浅圆仓里,粮食满仓,让人安全感满满。而在这些传统样式的粮仓附近,另一组"膀大腰圆、 白白胖胖"的新型粮仓十分引人注目。 这就是正在建设中的我国首批5座9000吨级气膜粮仓。它们高33米、内径24米,建成后的每座气膜仓都 能储藏约9000吨粮食。按发展代数划分,这属于我国第四代新型粮仓。 新型粮仓,新在哪里? 戴上安全帽和口罩,穿过两道密封门,记者来到正在建设中的粮仓内部,耳朵能明显感受 ...
