摘要
Crop germplasm resources are the material basis for the breeding of new varieties, and strategic resources for food production, ecological security and agricultural sustainable development. Constructing a scientific, environmental-friendly and energy-saving medium-term genebank is essential for preserving crop germplasm resources. However, the construction of medium-term genebank involves a wide range of subjects but lacks unified standard, which might result in many difficulties in the process of construction and application. According to the key parameters of refrigeration system for medium-term genebank, the cooling load was calculated and key system schemes were determined in this paper. Based on the calculation results and designed schemes, the equipment selection was discussed and the standards for construction of bank and monitoring system were proposed with the aim to provide references for germplasm genebank design and equipment selection.
作物种质资源是新品种选育的物质基础,是事关粮食生产、生态安全与农业可持续发展的战略资源。建设科学、环保、节能的中期库对于种质资源保护至关重要。由于中期库建设涉及学科广且没有统一的设计规范,因此其建设与应用困难重重。笔者从中期库制冷系统关键参数入手,计算了中期库制冷负荷,确定了关键系统方案,并根据计算结果与设计方案,探讨了中期库设备选型,同时对库体及监测系统的构建提出了具体要求,以期为种质库的设计和设备选型提供参考与借鉴。
