摘要
目前,我国化肥存在着施用不合理、利用率低及对环境污染严重等问题。为此,针对农业传统施用化肥存在的问题,设计了液态施肥机的探针注入式深层施肥机构,建立了探针的运动方程。作业试验表明,探针注入式深层施肥机构能够较好地深施液态肥料,可获得良好的液态肥料施用深度;液态施肥机满足了各种农艺要求,能够保证深施液态肥料的作业质量;探针注入式深层施肥机构设计合理,具有实用可行的特点。
Fertilizer is the food of agriculture. There are many problems during fertilizer using： illogicality, low using rate, serious environment pollution etc. Aiming at the problems about the agricultural traditional applied chemical fertilizer in our country, it designs the probe injection deep fertilization mechanism of the liquid fertilizer applicator and the movement equation. This mechanism could be applied to make liquid fertilizer deeper, and to get nice soil depth according to the experimentations. Meanwhile, the liquid fertilizer applicator could meet all the need of various agricultures, and could guarantee the experimental quality for applying liquid fertilizer deeply. The design of this mechanism is reasonably, practical and feasible.
