The invention is a fertilizer car which can adjust the rate of fertilizer application.It includes car body,Drive,Fertilizer transmission device and fertilizer application device；Among them,Drive,The fertilizer transmission device and fertilizer application device are installed on the vehicle body.The fertilizer speed changing device is connected with the driving device and driven by the driving device.The fertilizer application device includes a mixing part.The mixing part is connected with the fertilizer transmission device and can rotate driven by the fertilizer transmission device；The invention can change the rotation speed of the mixing part by controlling the fertilizer speed changing device.In order to adjust the rate of fertilization,It can be solved that the speed of fertilizer application of the existing fertilizer vehicle depends on the driving speed of the fertilizer vehicle.But the fertilization efficiency is low.It can adjust the fertilization rate according to the needs of different crops.And then improve the efficiency of fertilization can adjust the fertilization rate of the fertilizer truck.本創作為一種能調整施肥速率的施肥車，其包括有車體、驅動裝置、施肥變速裝置及施肥裝置；其中，驅動裝置、施肥變速裝置與施肥裝置裝設於車體，施肥變速裝置與驅動裝置相連結且受驅動裝置所驅動，施肥裝置包括有攪拌件，攪拌件與施肥變速裝置相連結且受施肥變速裝置所驅動而能轉動；本創作能透過操控施肥變速裝置來改變攪拌件的轉速，藉此來調整施肥的速率，可解決現有施肥車之施放肥料的速率係取決於施肥車的行駛速率，而帶來施肥效率低落的問題，提供一種能針對不同作物之需求調整施肥速率、進而提高施肥效率之能調整施肥速率的施肥車。
