1. 关键资源 2016-03-01 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,...
  2. Access Agricuture Training Video When you pick your tomatoes, if you want to keep them longer, you have to find a way of reducing the temperature. As availability of electricity at village level can be a problem, ways have to be found to lower the temperature of this fragile crop. Some farmers at...
  3. New, low-cost indicator of food dryness: DryCard In developing countries, mold growth on dried foods can result in postharvest losses for farmers and unsafe foods for consumers. Food will not mold if it is properly dried, but smallholder farmers do not have access to a cost-effective way of...
  4. Growing, harvesting, preserving and marketing food that benefits from chilling or freezing is no easy process. Middlemen, lack of education, poor technology transfer, difficult or non-existent agriculture credit, unclear market linkages, tradition, volume and production inconsistencies, lack of...

  6. Abstract, Energy Procedia, 2016 The paper presents actual knowledge concerning the indirect evaporative cooling (IEC). This cooling technology is promising to develop in the near future due to its very low energy consumption and high efficiency in its range of applications. The review is...
  7. With an increasing interest in the use of refrigerants with a low global warming potential (GWP), engineers are looking to nature’s refrigerant – R-718, better known by its chemical formula, H2O. Evaporative cooling is not a new concept; its use in buildings can be traced back thousands of years....
  8. Kate and Ron Khosla started Huguenot Street Farm in New Paltz, NY in 1999. As small farmers, they learned the value of money the hard way, literally pulling it a few cents at a time from the ground. So when they looked into adding a walk-in cooler to the farm, the idea of spending $3,500 for a...
  9. Much of the post-harvest loss of fruits and vegetables in developing countries is due to the lack of proper storage facilities. While refrigerated cool stores are the best method of preserving fruits and vegetables they are expensive to buy and run. Consequently, in developing countries there is...
