有必要为以低活性粘土为主的热带高地发展可行的耕作系统；这种系统应确保可持续的作物生产，同时保护土壤资源基础。胡同种植有潜力满足这一需求。十多年来，在不同的农业生态区试验了巷道种植技术，结果各不相同。到目前为止获得的结果表明，湿润和半湿润地区的高盐基土壤具有最好的潜力，在这种低化学投入的生态环境中可以维持作物生产。需要对其他生态区进行进一步研究，特别是纳入适应更好的或本土的灌木树篱物种。强调了巷道种植技术的潜力和局限性，并讨论了未来研究的领域。
There is a need to develop viable farming systems for tropical uplands dominated by low-activity clay soils; such systems should ensure sustained crop production while protecting the soil resource base. Alley cropping has the potential to meet this need. For over a decade, the alley cropping technique has been tested, with varying results, in various agroecological zones. Results obtained thus far show that the best potential is on the high base-status soil in the humid and subhumid zones, and that crop production can be sustained in this ecozone with low chemical inputs. Further research is needed for other ecozones, particularly with inclusion of better adapted or indigenous hedgerow species. The potential and limitations of the alley cropping technique are highlighted and areas of future research discussed.
