Abstract

The success of weed control is critical for our food security. Non-chemical weed control is a promising technique in sustainable agriculture to ensure the food security. In this review, multiple directed energy weed control methods are reviewed with a specific focus on laser and optical radiation weed control. The mechanisms of the weed control in terms of adverse ablation, radiation thermal effects, and molecular-level damages are systematically reviewed. In particular, the underlying mathematical models determining the dose and response relationship of the weed control are also analyzed for a rigorous study of the physical law of the control process. Challenges of applying the techniques into practice are also illustrated to guide practical weed control applications.

激光和光辐射除草:重要综述
成功控制杂草对我们的粮食安全至关重要。非化学除草是确保粮食安全的可持续农业中一项前景广阔的技术。本综述对多种定向能杂草控制方法进行了综述,重点关注激光和光辐射杂草控制。从不利烧蚀、辐射热效应和分子水平破坏等方面系统地评述了除草机制。特别是,还分析了决定除草剂量和反应关系的基本数学模型,以便对控制过程的物理规律进行严格研究。此外,还阐述了将这些技术应用于实践所面临的挑战,以指导实际的除草应用。
