摘要

在厄瓜多尔,农民对马铃薯种子退化的管理方法很差。这可能与对农民经历种子退化和应对能力的理解不足有关。我们通过回答:农民是如何经历种子退化的?;当农民的种子退化时,他们会采取什么做法?;经历退化是决定农民如何在不考虑收入的情况下更换种子的关键因素吗?我们分析了通过农民焦点小组讨论、农民调查和访谈以及厄瓜多尔就业状况调查在厄瓜多尔收集的数据。我们发现大约有一半的农民经历了退化。农民经历了低产量、种子外观变化、作物衰弱和种子生理问题。当农民经历退化时,他们更换种子,寻求技术建议,应用更多的农业投入,或种植其他作物。收入是促使农民改变种子替代做法的重要因素。

Farmers Experiencing Potato Seed Degeneration Respond but Do Not Adjust Their Seed Replacement Strategies in Ecuador

In Ecuador, farmers poorly adopt practices to manage potato seed degeneration. This could be related to the deficient understanding of the farmers’ capacity to experience seed degeneration and respond to it. We contribute to this understanding by answering: How do farmers experience seed degeneration?; What practices do farmers implement when their seed is degenerated?; and Is experiencing degeneration the pivotal factor determining how farmers replace their seed regardless their income? We analysed data collected in Ecuador through farmers’ focus group discussions, farmers’ surveys and interviews, and the Ecuadorian employment status survey. We found that approximately half of the farmers experienced degeneration. Farmers experienced it through low yields, change in seed appearance, crop weakening, and seed physiological problems. When farmers experienced degeneration, they replaced their seed, sought for technical advice, applied more agricultural inputs, or grew other crops. Income was an important trigger for farmers to change their seed replacement practices.
