摘要

本科生的实践研究可以培养年轻学者的创新能力和批判性思维,从而深入研究现实世界的挑战。具体来说,探索水资源利用与农业产量之间的重要关系,可以促进学术成长,并在环境约束日益加剧的时代,成为解决全球粮食安全问题的关键。本文以通过本科生研究调查水资源管理与作物产量之间的复杂关系为例进行说明。本科生通过收集、处理和分析灌溉和旱地生产系统下大豆的破坏性(作物生物量样本)和非破坏性(株高、节间和叶片叶绿素含量)作物系统数据,获得了实践研究经验,并与农民密切合作。学习成果包括:确定当前的研究问题和研究地点的选择、田间研究过程中的科学决策、在确保研究交流技能的同时发展批判性思维,以及在数据收集和分析过程中通过技术进行质量保证和质量控制。研究强调,在采取适当的质量控制和保证步骤后,利用非破坏性植物健康和生长指标以及植物生物量,观察到灌溉大豆和非灌溉大豆之间的不同表现。据统计,灌溉大豆在成熟时的平均株高(灌溉:97.0±1.7 厘米 vs. 非灌溉:37.4±0.6 厘米;p<0.01)和主茎节数(灌溉:19.5±1.2 vs. 非灌溉:12.6±0.8;p<0.01)方面优于非灌溉大豆。这项研究的结果有助于确保未来种植系统项目的质量控制和保证。通过农业生态系统研究,我们展示了本科生研究机会在培养下一代问题解决者方面的重要性和作用。

On-field Agroecosystem Research Experience: An Undergraduate Perspective

On-field Agroecosystem Research Experience: An Undergraduate Perspective

Undergraduate hands-on research can foster innovation and critical thinking among young scholars to delve into real-world challenges. Specifically, exploring the critical nexus between water usage and agricultural yield, can foster academic growth and holds the key to addressing global food security in an era of increasing environmental constraints, where students can unlock insights crucial to enhancing crop yield and sustainability. Investigating the intricate relationship between water management and crop productivity through undergraduate research is exemplified in this article. Undergraduate students acquired hands-on research experience by collecting, processing, and analyzing destructive (crop biomass samples) and non-destructive (plant height, nodes, and leaf chlorophyll content) cropping system data on soybeans under irrigated and dryland production systems, where they worked closely with the farmer. Identifying the current research problem and study site selection, scientific decision-making during the field study, developing critical thinking while ensuring research communication skills, and quality assurance and quality control through technology during data collection and analysis were learning outcomes. The research highlights the observed distinct performance between irrigated and non-irrigated soybeans using non-destructive plant health and growth indicators with plant biomass, following appropriate quality control and assurance steps. Statistically, irrigated soybeans outperformed non-irrigated soybeans in terms of average plant height at maturity (irrigated: 97.0±1.7 cm vs. non-irrigated: 37.4±0.6 cm; p<0.01) and number of nodes on the mainstem (irrigated: 19.5±1.2 vs. non-irrigated: 12.6±0.8; p<0.01). Findings from this study can help ensure quality control and assurance in future cropping system projects. Through the agroecosystem study, we exhibit the importance and role of undergraduate research opportunities in developing the next generation of problem solvers.
