  1. This article is from ECHO Asia Note #28 农户自产饲料贡献了一个更加可持续发展的农业系统。作物残茬和动物粪便是 植物生产营养循环的一部分。通过使用喜温的堆肥、蚯蚓培养、博卡西和/或绿肥 就能降低投入的成本。农户自产饲料也能通过管理和利用既得资源来减少费用。小 规模的农户购买商业饲料来喂鸡特别是小鸡是非常昂贵的。在这篇 ECHO 亚洲期刊 的文章中,我们将探索多种可供选择的小规模家禽饲料。





  2. 热带作物的叶子,如卡亚(Cnidoscolus aconitifolius)和木薯(Manihot esculenta)含有氰苷,当这些植物细胞被破坏会释放有毒的氢氰酸(HCN;也被称为氰化物或氰酸)。不烹煮地食用这些植物会导致氰化物中毒,其影响取决于氰化物含量和人或动物食用这些植物的时间长短。新西兰食品安全局的一份信息表描述了植物中的氰苷对人类健康的影响。要确定一种植物是否可以安全食用,使用Cyantesmo纸进行简单的氰化物测试非常有帮助。

  4. 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,...





  5. This article is from ECHO Asia Note #27 微生物是不能用肉眼直接观察到的微小生物;他们包括真菌类、藻类和细菌类(Rao, 1995)。这些小 生物存在于任何地方:水里、空气里和土壤里。在农业上,微生物的数量在堆肥、动物粪便和IM(本地微 生物(Indigenous Microorganisms))液里、EM(有效微生物(Effective Microorganisms))的液体里特别多。微生物是土壤的重要组成部分,它们帮助分解有机物,也将岩石和空气中的营养物质转化成农作物可用的形式,还帮助固定土壤结构(Tisdall, 1994; Hayat et...
