【 摘 要 】

Recently in Russia and in the near and far abroad the vermikomposting of organic wastes has been widely adopted. In a vermiculturing the species of worms specializing in eating of vegetable oddments and excrement of mammals are used, it is Eisenia foetida (Savigni, 1826) and its subspecies E.f. foetida, E. Fandrei, and also an ordinary earthworm which is Lumbricus terrestris, the small red worm L. rubellus and types of Dendrobaena subrubicunda and D. Veneta. Many researchers consider that the vermicomposting promotes a solution of the problem of utilization of large numbers of household garbage, rainfall of sewage, wastes of the food industry, the cellulose-paper and woodworking, tanning, hydrolyzing industries, and branches of agriculture. The technology of a vermiproducting supposes the preparation of substrata. Such receptions as humidification of wastes; their aeration, neutralization; crushing and homogenization, use of various excipients in substrata (straw, rotten hay, opit, peat, some quantity of the mineral soil) reduce terms of preparation of substrata for a vermiculture. Our researches were devoted to definition of an optimum ratio of ingredients in the substrata prepared for a vermiculturing on the basis of a bird's dung for successful adaptation of Eisenia foetida (Sav.) to them.
