THE INFLUENCE OF MICROFERTILIZERS ON DYNAMICS OF ACCUMULATION OF MEDICINAL VALERIAN BIOMASS

Abstract

In the researches conducted on sod-podzolic sandy-loam soil laid by the exterminated loam, it was set that application of microfertilizers: boric, zinc, copper - on a background of organic and mineral fertilizers (60 т/ha of manure + N₁₃₅ P₆₀ K₁₂₀) influences on forming of biomass of medicinal valerian. Microelements by the efficiency of their influence on forming of biomass of roots and rhizomes of valerian both at the soiland and unroot bringing are possible to be disposed in the next order of decrease: Zn > В > Cu. Variants with the use of the unroot additional fertilizing by zinc (Background + Zn_{(0,15+0,15+0,15)}) and especially with joint application of zinc and bor (Background + В_{(0,1+0,1+0,1)} Zn_{(0,1+0,1+0,1)}) have the most intensity of accumulation of general and underground biomass.
