摘要

摘要地下水位管理是加拿大东部维持作物生产的一种推荐做法。谷物玉米在气候变化下非常容易受到影响，采取更好的管理措施几乎是必要的。建议采用控制排水和地下灌溉的做法之一。一个主要问题是农民是否会采用这种做法。由于新做法的采用往往取决于其对农场净收益的影响，因此对采用地下灌溉的控制排水进行了经济分析。结果表明，在粮食生产农场，该技术仅略优于传统排水系统的基线技术。

Economic analysis of the controlled drainage with sub-irrigation system: a case study of grain-producing farms in Quebec and Ontario

Abstract Water table management is a recommended practice to maintain crop production in Eastern Canada. Grain corn is highly susceptible under climate change and adoption of better management practices is almost a necessity. Use of controlled drainage with sub-irrigation is one of the practices recommended. A major question is whether farmers would adopt this practice. Since adoption of new practices often depend on their impact on farm net returns, an economic analysis of controlled drainage with sub-irrigation was undertaken. Results suggest that on grain producing farms, this technology is only slightly superior to the baseline technology of conventional drainage system.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
