High density nondestructive collection method of airborne crop nitrogen information

The invention relates to a high density nondestructive collection method of airborne crop nitrogen information, which belongs to the technical field of crop production, and mainly comprises the following steps: collecting crop canopy leaf nitrogen information by a crop nitrogen information sensing transducer, automatically adjusting and keeping the sensing transducer to be in a gesture suitable for collection by a following self-adapting balance adjustor, hanging and adjusting the sensing transducer to be in a position and an azimuth suitable for collection by an adjustable hanging bracket, and receiving and storing the nitrogen information sent from the sensing transducer by a crop nitrogen information wireless receiver. The continuous collection method of the airborne crop nitrogen information can realize the high density obtainment of the information on the surface of large-scale farmland in a mechanical operating mode and is the more applicable agricultural information equipment desired in the present act
