摘要

在商业果园中,花条可以提供许多经济效益,包括减少一种有问题的害虫——红苹果蚜虫(Dysaphis plantaginea [Passerini])对作物的损害。为了探讨这种效应的经济成本和效益,我们建立了一个生物经济模型,比较多年生野花带的建立成本和机会成本,以及在高低虫害压力下减少车前草果实损害所带来的产量增长效益。这是在三种情况下计算出来的:(1)陆地上的花带本来是标准草岬的延伸,(2)陆地上的花带本来可以用来生产苹果,(3)果园中心的花带。仅通过减少车前草果实损害,我们的研究表明,在海岬建立花带是一项积极的经济投资。如果没有非作物用地,在果园的中心而不是边缘建立花带,可以通过为花带两侧的作物提供利益来收回机会成本。本文的研究可以帮助指导花条的最佳放置,并为这些计划提供补贴价值。

Perennial Flower Strips Can Be a Cost‐Effective Tool for Pest Suppression in Orchards
Flower strips can provide many economic benefits in commercial orchards, including reducing crop damage by a problematic pest, rosy apple aphid (Dysaphis plantaginea [Passerini]). To explore the financial costs and benefits of this effect, we developed a bio‐economic model to compare the establishment and opportunity costs of perennial wildflower strips with benefits derived from increased yields due to reduced D. plantaginea fruit damage under high and low pest pressure. This was calculated across three scenarios: (1) a flower strip on land that would otherwise be an extension of the standard grass headland, (2) a flower strip on land that could otherwise be used to produce apples and (3) a flower strip in the centre of an orchard. Through reduction of D. plantaginea fruit damage alone, our study shows that flower strips on the headland can be a positive financial investment. If non‐crop land was not available, establishment of a flower strip in the centre of an orchard, instead of the edge, could recoup opportunity costs by providing benefits to crops on both sides of the flower strip. Our study can help guide the optimal placement of flower strips and inform subsidy value for these schemes.

期刊介绍: Published on behalf of the Agricultural Economics Society, the Journal of Agricultural Economics is a leading international professional journal, providing a forum for research into agricultural economics and related disciplines such as statistics, marketing, business management, politics, history and sociology, and their application to issues in the agricultural, food, and related industries; rural communities, and the environment. Each issue of the JAE contains articles, notes and book reviews as well as information relating to the Agricultural Economics Society. Published 3 times a year, it is received by members and institutional subscribers in 69 countries. With contributions from leading international scholars, the JAE is a leading citation for agricultural economics and policy. Published articles either deal with new developments in research and methods of analysis, or apply existing methods and techniques to new problems and situations which are of general interest to the Journal’s international readership.
