关键资源This article is from ECHO Asia Note # 37. 在亚热带和热带种子储存是一项挑战。如果没有干燥和冷环境，种子的质量可能会急剧恶化。储藏时的高温高湿会加速种子的新陈代谢并且促使食种虫增殖（Lale and Vidal, 2003; Upadhyay and Ahmad, 2011）。冰箱、除湿机和杀虫剂等技术能防止这些毁坏种子的情况发生，但是热带地区的小型农户不一定能利用这些技术。很多当地传统方式被用于防止虫害。一些处理剂通常在种子储存前添加到种子中，为了毒杀害虫，或者破坏和阻止昆虫在种子周围移动。一些处理剂能非常有效地减少害虫生长，...

关键资源 This article is from ECHO Asia Note #27 种子储存的原则 当要建一个“冷藏室”或“种子储藏室”来达到保持种子活性的目的时，最先要考虑的种子储存的最佳条件。在ECHO 亚洲期刊14（ECHO Asia Note 14）（2012 年6 月），我们分享了真空密封和冷藏的对比结果，并强调对于种子储存湿度和温度控制的重要性。我们发现湿度控制（真空密封）比温度控制（冷藏）更有效地保存种子活性。在这个ECHO 亚洲的实验中，热带种子最佳的储存方式是干燥后（为了保持较低的种子湿度）立刻真空密封，然后把种子储存在较低的温度之下。要设计一个最适宜种子储存的冷藏室，...

2019-01-20 Given the proper facilities necessary to store seeds long-term, whereby low temperature and low humidity are kept stable over time, it is very possible to store most orthodox seeds for several years at a time in the tropics (Harrington, 1972). Unfortunately, implementation and maintenance of the...

2019-07-24 Patrick Trail, an ECHO Asia staff member, compiled a picture-based guide for constructing earthbag houses for seed storage in Asia. Earthbag houses have been used by multiple seed banks in Asia as an alternative to more costly conventional structures. At this writing, construction of an earthbag...
