摘 要:天津东郊盐碱土微生物分布及土壤酶活性靳素英,崔明学,蔺继尚(中国科学院沈阳应用生态研究所,沈阳110015)Distributionofmicroorganismsinsaline-alkalisoilatcasternsuburbsofTianji...The study shows that the quantity of soil microorganisms and the activity of soil enzymes are related with crop kind and soil organic matter content. Rice soil has the highest quantity of microorganisms,and herbage soil has the lowest one. The number of microorganisms is much higher in 0~10cm than in 20~30cm soil layer. Protease and urease have a much higher activity in rice soil than in beer, herbage and wheat soils. Catalase activity isthe highest in beer soil, but the lowest in herbage soil.
关 键 词:SOIL MICROORGANISM SOIL enzyme activity SALINE-ALKALI SOIL
