摘要：

Point injection of liquid fertilizer has shown promise as an alternative to standard surface or subsurface fertilizer application, particularly with no-till and ridge-till planting systems. Field-scale point injector applicators are difficult to use in small plots, especially with labeled fertilizer materials such as 15N. This paper describes the construction and use of a small, inexpensive fertilizer application system, which simulates fertilizer injection by a large point injection applicator. Use of the applicator for 3 yr has shown the unit to be relatively accurate, durable and compatible with a variety of fertilizer materials.
