INFLUENCE OF MICROELEMENTS ON BIOCHEMICAL PARAMETERS OF TEA

The microelements brought through a leaf, allow to receive qualitative raw materials for receiving ready tea, stimulating signs genetically put in a plant at the minimum costs of their cultivation (without watering of plantations and unlimited increase in doses of macro fertilizers). Processing of plants by copper (r = 0,72), manganese (r = 0,76) and iron (r = 0,82) promote increase in raw materials of the content of tannin to 33,8 - 34,29% (on control - 30,72%) and for 0,9 - 1,4% of extractive substances (control - on the average 41,6%). The components of a leaf which are responsible for quality of finished production are dependence with brought microelements. And, dependence direct: at increase in quantity of microelements, in a plant there is an increase in qualitative characteristics.
