Abstract

In order to solve the ecological security problems caused by chemical pesticide dependence in modern agricultural pest control, this paper puts forward a technical system of "plant protection drone-multi-channel LED light source-insect biological rhythm". Taking insect light perception mechanism as the core, combined with spectral power distribution (SPD) analysis and natural light rhythm characteristics, a multi-channel LED light source system which can dynamically simulate natural spectrum is designed, and a precise regulation strategy based on time series is constructed. The effectiveness of the technology is verified by field experiments. By analyzing the dynamic law of solar spectrum (light intensity, color temperature, SPD), this paper optimizes the spectrum combination and operation sequence of LED light source, and realizes the directional intervention on the target insect rhythmic behavior. The results show that the mating inhibition rate of noctuid pests can reach 76.2%, and the feeding efficiency of parasitic wasps can be improved by 68.4%, which provides theoretical support and engineering practice scheme for the intelligent and accurate development of green plant protection technology.
