PROBLEM TO BE SOLVED: To provide a pesticide spraying method using a drone in which chemicals such as pesticide can be sprayed in a predetermined spraying area evenly uniformly and efficiently.SOLUTION: A matrix of a spraying partition width is created from a near-infrared light image photographed using a drone for farmland aerial photography. Further, an image is obtained by averaging every spraying partition width. A spraying plan screen of the image is obtained by NDVI based on this image. A calculation of a spraying amount is performed after estimating the most effective additional fertilization time. A necessary spraying amount every spraying partition width, spraying patterns A-E and a spraying rate are determined by the spraying width determined from the flight altitude of the drone. The drone for spraying the pesticide is used and it is automatically sprayed, and then the smoothing of protein contents is performed.SELECTED DRAWING: Figure 5【課題】本発明は、農薬などの薬剤を所定の散布領域内にムラなく一様に、且つ効率的に散布することができるドローンを使用した農薬散布方法を提供する。【解決手段】農地空撮用ドローンを使用して撮影した近赤外線画像より散布区画幅の行列を作成し、更に散布区画幅毎に平均化して画像を得、この画像を基にNDVIにより画像の散布計画画面を得、最も効果的な追肥時期を予測した上で、散布量の計算を行い、ドローンの飛行高度から決定される散布幅により必要な散布区画幅毎の散布量、散布パターンA~E、散布速度を決定し、農薬散布用ドローンを用いて自動で散布し、タンパク質含有量の平準化を行う。【選択図】図5
