摘　　要：为提高造林机械的自动化水平,需要在检测、控制和机械设计等各方面进行研究.该文就造林机械在自动检测方面的方法,进行了尝试性的探讨,提出了运用超声技术对造林地植苗点进行选择这一方法,并从超声检测理论上对其可行性进行了分析,进而搭建了一个用于进行模拟实验的检测系统.通过实验和数据分析,认为将超声技术运用到造林机械的自动检测上是可行的.The fields of detecting, controlling and machine designing should be studied to improve the automatic control level of planting machines. This paper introduced a tentative discussion on the method of automatic detecting, and presented a way of using ultrasonic technology to choose the planting point of the area. The feasibility of the detecting part was analyzed on the basis of ultrasound detecting theory, and then a detecting system for simulative experiment was built. The conclusion from the test and data analysis shows that it is feasible to use ultrasonic technology in detecting obstacles in the planting areas.
