FIELD: vermiculite cultivation, in particular, selection of optimal substrates for cultivation of annelids. ^ SUBSTANCE: apparatus has reservoir for layer-by-layer placement of test samples therein and of sample with annelids in spaced apart relation with respect to one another. Reservoir is made rectangular and is provided with front detachable wall divided into sections by means of detachable partitions having height lower than that of reservoir. Sample with annelids is positioned above test samples. ^ EFFECT: simplified construction of apparatus, increased quantity of substrate samples tested for one cycle, and reduced time spent for experiment. ^ 1 dwg |
