多肥混施精准变量施肥装置设计与试验OA

To solve the problems of inaccurate ratio,delayed fertilization response,and poor adaptability to field environ-ment in traditional fertilization devices during synchronous application of multiple fertilizers,a precision variable fertili-zation device for multi fertilizer mixed application is proposed,which adopts a dual motor dual metering disk collabora-tive drive to achieve independent metering and real-time ratio of multiple fertilizers such as nitrogen,phosphorus,and potassium.By introducing a feedforward regulation based on target formula and an adaptive compensation algorithm based on flow deviation,the system can automatically adjust the fertilizer supply based on soil nutrient differences and changes in operating speed,improving the accuracy and dynamic stability of formula fertilizer execution.The article aims to provide technical reference for the development of formula fertilization and green and efficient soil management equip-ment.
