Abstract:  Fertilization and pesticide application of sweet potato is a key process in sweet potato planting. The lack of machinery for fertilization and pesticide application of sweet potatoes not only hinders the mechanization of the whole process but also restricts the development of the sweet potato industry. This paper used three different fertilization and pesticide application methods used in the current sweet potato production process to analyze the advantages of layered fertilization and pesticide application methods in sweet potato ridge cores. By combing the development status of sweet potato fertilization and pesticide application machinery at home and abroad and comparing the machines that adopt different ridge fertilization methods, it was concluded that the existing sweet potato fertilization and pesticide application machinery had problems ofoverfertilization, inability to deploy fertilizer in the core and layers, and few specific equipment for fertilizer application. This article systematically analyzed and summarized the current sweet potato fertilization and pesticide application characteristics and machine development trends in China andconcluded the influencing factors that led to the low level of development of sweet potato fertilization and pesticide application. It also pointed out that the focus of promoting the development of sweet potato fertilization and pesticide application machinery was to deepen the integration of agricultural machinery and agronomy, accelerate the research and development of light and simple machinery, and strengthen the promotion of mechanization. This paper can provide a reference for the further development of sweet potato fertilization and pesticide application machinery.

摘要： 甘薯施肥施药是甘薯种植过程中的关键环节,而甘薯施肥施药专用机械的匮乏,不仅阻碍甘薯种植全程机械化进程,更制约着甘薯产业的发展。本文结合当前甘薯生产过程中使用的三种不同施肥施药农艺,分析甘薯垄芯分层施肥施药方法的优势,并通过梳理国内外甘薯施肥施药机械发展现状,对采用不同起垄施肥方式的机具进行比较,得出现有甘薯施肥施药机械存在肥药施用量大、肥药无法施于垄芯内、肥药无法分层施放和施肥施药专用机具少等问题。本文通过系统分析和总结我国目前甘薯施肥施药特点和机器发展趋势,归纳导致甘薯施肥施药总体发展水平低的影响因素,并提出促进甘薯施肥施药机械发展的重点在于加深农机农艺融合、加快轻简型机具的研发和加强机械化推广,为甘薯施肥施药机械的进一步发展提供参考依据。
