摘要: 乐陵金丝小枣区生态环境地质研究表明,层状沉积的河流相及其变异体,心、底土层层位为壤质、粘壤质的土体构型,以不稳定原生矿物为主的土壤,中性或微碱性的重碳酸盐型地球化学环境,钾素丰富、理化性状良好的潮土、褐土化潮土、盐化潮土为该枣区生态环境地质特征的重要标志。对枣生长发育适宜区进行了划分。

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
