Hyperspctral Inversion Of Physical And Chemical Parameters Of Plants Reclaimed With Microorganism And Its Soil

Aiming to find possiblility to monitor the sensitive indices of arbuscularmycorrhizal fungi (AMF) with hyperspectral remote sensing, this paper studied thehyperspectral inversion characteristics of the physical and chemical information ofsoybean leaves reclaimed with microorganism and rhizosphere soils. The difference ofAMF effect on the nutrients of leaves and rhizosphere soils was mastered. Based onthe analysis of difference of spectral reflectance of leaves and rhizosphere soils indifferent treatments, the characteristic bands were selected, the affecting factors werefound, and hyperspectral estimation models for physical and chemical information ofsoybean leaves and rhizosphere soils were built. The results show that the inoculationof AMF and its combination with other microorganisms can promote the uptake ofnutrients in soil for soybeans, improve soil properties, and change spectral reflectanceof plant leaves and rhizosphere soils. The relationships among AMF, physical andchemical information and the spectral reflectance of soybean leaves and rhizospheresoils were revealed. The chlorophyll, N, P and water are main indices to reflect theeffect of AMF on growth of plants, which can be grasped with hyperspectral inversionof these indices. It is possible and effective to monitor the impact of AMF on plantsand rhizosphere soils with hyperspectral technology.
