Functional aspects of formation harvest cleanliness in condition of mineral pollution of agricultural lands

摘要

Main principles of biological control of the intensity of the pollutant flow in system soil-plant have been analysed. It is demonstrated, that functional state of plant organism is so far significant factor in determination of rate of pollutant turn on trophycal chains as physico-chemical property of mineral elements, level of pollution and type of soil, climate, genetic properties of plants. Two main pathway of functional control intensity of pollutant flow such as possibility of plant to alter (to increase) mobility mineral elements into soil and change ions exchangeable characteristic of plant tissues, which determin degree of attraction and capacity of accumulation of nonbiogenic element by a plant have been considered. Significance of the functional control into decrease pollution of agricultural production have been discussed.
