Three protozoa (Bodo edax, Colpoda cucullus, Amoeba proteus) were isolated from soil. The porous simulation with glass bead, soil column and root box incubation experiments were made to study the association of protozoa movement with phosphorus translocation and its influencing factors. The effects of protozoa on corn growth and corn straw mineralization were also involved. The results showed that protozoa movement in glass bead column was greatly controlled by the pore sizes. Bodo edax, about 5-7 m, could pass through the pores of 28-20 11 m in diameters. Colpoda cucullus (30-60 m) could move through the pores of 155~116 m. However, no Amoebaproteus(100~150 m) was found in the effluents from all the columns. All the three protozoa made 32P redistribution in soil column.

本研究利用土壤中常见的3种原生动物(梨波豆虫Bodo edax、僧帽肾形虫Colpoda cucullus、大变形虫Amoeba proteus)，通过玻璃珠孔隙模拟、土柱及根箱培养试验，研究3种原生动物运动与磷素运移之间的关系及其影响因素，以及原生动物对玉米磷素营养的影响，同时对3种原生动物在玉米秸秆分解中的作用做了初步的探索，研究结果表明：原生动物的运动与孔隙密切相关，Bodo edax(5～7μm)能够穿过28～20μm孔隙，Colpoda cucullus (30～60μm)只能穿过155～116μm的孔隙，而Amoeba proteus(100～150μm)不能从玻璃柱中流出。
