Abstract

Abstract Overuse of fertilizer is detrimental to the sustainability of crop production from an economic and environmental perspective. While rice side-deep fertilization technology can significantly improve fertilizer utilization efficiency, improve crop yield and reduce environmental pollution caused by improper use of fertilizer compared with conventional fertilization methods. Therefore, side-deep fertilization technology has an important role in the sustainable development of agriculture. This article describes fertilizer selection, side-deep fertilization devices and the effects of side-deep fertilization technology on rice plants and soil. We summarize the types and characteristics of side-deep fertilizers and their ratios and modes. The basic principles and characteristics of the key components of mechanical fertilization devices are described in detail, including fertilizer discharging devices (rotating disc type, outer groove wheel type, screw type), fertilizer conveying devices (pneumatic, mechanical forced type) and sensors. The effects and mechanisms of side-deep fertilization on rice growth, yield, quality, fertilizer utilization efficiency and soil microorganisms are summarized. Finally, based on current research on side-deep fertilization, future directions are identified to aid the development of this promising technology.

水稻侧深施肥的发展现状与趋势

摘要从经济和环境角度来看，化肥的过度使用对作物生产的可持续性有害。而水稻侧深施肥技术与传统施肥方法相比，可以显著提高肥料利用效率，提高作物产量，减少因施肥不当造成的环境污染。因此，侧深施肥技术在农业可持续发展中具有重要作用。本文介绍了水稻的肥料选择、侧深施肥装置以及侧深施肥技术对水稻植株和土壤的影响。概述了侧深肥料的类型、特点及其配比和施用方式。详细介绍了机械施肥装置关键部件的基本原理和特点，包括卸肥装置（转盘式、外槽轮式、螺杆式）、输肥装置（气动式、机械强制式）和传感器。综述了侧深施肥对水稻生长、产量、品质、肥料利用效率和土壤微生物的影响及其机理。最后，在目前侧深施肥研究的基础上，确定了未来的发展方向，以帮助这项有前景的技术的发展。

期刊介绍： Renewable Agriculture and Food Systems (formerly American Journal of Alternative Agriculture) is a multi-disciplinary journal which focuses on the science that underpins economically, environmentally, and socially sustainable approaches to agriculture and food production. The journal publishes original research and review articles on the economic, ecological, and environmental impacts of agriculture; the effective use of renewable resources and biodiversity in agro-ecosystems; and the technological and sociological implications of sustainable food systems. It also contains a discussion forum, which presents lively discussions on new and provocative topics.
