Abstract In order to solve the problems of time-consuming, low-precision, and incomplete image details when extracting soil physical and chemical information, this paper proposes a soil physical and chemical information extraction method based on hyperspectral remote sensing technology. Through graying, filtering, and contrast enhancement of remote sensing image, the extraction model of soil physical and chemical information is established, and the thermal intensity of hyperspectral remote sensing image is adaptively fused. The template matching technology is used to enhance the information of the sand soil hyperspectral remote sensing image. The hyperspectral remote sensing feature is used to extract the image feature, and the brightness component is used to analyze the detail transmission of the image. The simulation results show that the method has high accuracy in extracting physical and chemical information of sand, and the resolution and accuracy of image details are good, which can effectively improve the recognition ability of hyperspectral remote sensing image features of Jerusalem artichoke planting sandy soil.

Introduction Jerusalem artichoke is a kind of ginger herb which has been growing for many years. It is 1-3 meters high, and its underground stem and fibrous roots are very developed. Its stem is erect, branched, and covered with white bristles or bristles. Its leaves are usually opposite and petiolate, but upper leaves are alternate; lower leaves are ovate or ovate elliptic (Razavian et al. 2016). The number of flowering affects the size of flower head. Generally, the larger flower head grows at the end of plant branch, with 1–2 linear lanceolate bracts, erect, ligulate flowers usually 12–20, tongue yellow, spreading, long oval, tubular flower corolla yellow, 6 mm long. Achenes small, cuneate, with 2–4 hairy awns at the upper end.

North America, it was introduced into Europe in the seventeenth century and then into China. Its underground tubers are rich in fructose polymers such as starch and inulin. It can be used for eating, cooking or porridging, salting vegetables, drying Jerusalem artichoke, or making starch and alcohol (Yang 2015). The planting near the house has the function of beautification. Jerusalem artichoke is known as “common crop for human and livestock in the 21st century” by FAO of
