SUBSTANCE: method involves process and objects arranged in predetermined manner, and place planned according to relief, with geographic and other necessary factors being taken into consideration so that directions of natural air flows are corrected. Agricultural production includes complex greenhouses, heat accumulator, basin, garden, and wind shield. Air flow directed into garden is saturated with water vapors in gaseous state if increase in temperature is desirable when it is close to minimal admissible value, and in small droplet state when lower temperature is desirable. Processor functions as central controller. Objects of branches in agricultural production are selected so that objects of previous branches make raw material for objects of subsequent branches. Furthermore, joint mutually useful development of these objects at suitable conditions is possible. These conditions are created in complex greenhouse units intermediate with regard to said branches. General-purpose containers with raw material are conveyed through said complex greenhouse units. This results in multiple sequential-parallel utilization of raw materials in number of branches of industry. Method stipulates employment of useful relations between populations of organisms - objects of agricultural branches of industry: symbiosis and, according to kind of symbiosis, natural selection.
