Abstract
A crop growth sensing apparatus and method supporting agricultural machinery variable-quantity fertilization, includes a shock-absorbing support, a shock-absorbing frame, and a cantilever beam. The shock-absorbing support is connected to an agricultural machinery vehicle frame. The cantilever beam is pivotally connected above a shock-absorbing spring of the shock-absorbing support. The cantilever beam, by means shock-absorbing springs mounted thereabove and thereunder, is pivotally connected to the shock-absorbing frame. The shock-absorbing frame is fixedly connected to a crop growth sensor. The crop growth sensing method employs an engine vibration model of the agricultural machinery and a vibration model for vehicle wheels and farmland road surface as excitations in analyzing vibrations of a crop growth multispectral sensor shock-absorbing apparatus to determine the number and mount positions of sensitive elements of the crop growth multispectral sensor. Also provided are a self-balancing apparatus and a self-balancing method for the crop growth multispectral sensor.
