Abstract: Studies on the characteristics of ecological environment in Leling jijithus producing area show that the soil parent materials are layer-sedimentary river facies and their variations, and the texture of the topsoil and subsoil are clay loam.The main soil minerals are unstable original minerals.The geochemical characteristics of the environment are neutral and/or slight alkali bicarbonate.The soils are fluvo aquic, gray fluvo aquic, salinized fluvo aquic soils with a plenty of Kand good physicochemical properties.These characteristics are the typical geological environmental symbols of the jijithus producing area.

Key words: Leling jijithus, Eco-environmental geological characteristic, Primary mineral, seed coating, actinomycetes agent, biomass, root growth, photosynthesis
