Uticaj prihranjivanja na rast jednogodišnjih sadnica smrče u različitim supstratima

Abstract

Prikazani su rezultati uticaja prihranjivanja osnovnim makroelementima (azot fosfor, kalijum) na rast i razviće jednogodišnjih sadnica smrče (Picea abies L. Karst) odgajenih u kontejnerima na 4 različita supstrata u rasadničkim uslovima. Konstatovan je povoljan uticaj prihranjivanja na sadržaj mineralnih elemenata u četinama, visinu biljaka, prečnik u korenovog vrata dužinu i masu četina, masu korena, kao i fiziološku vitalnost sadnica smrče. Utvrđeno je da efekat prihranjivanja zavisi od tipa supstrata.

The results of the influence of main macronutrients (N, P, and K) on growth and development of spruce (Picea abies L. Karst) one-year old seedlings are presented. They were grown in containers, in nursery conditions, on four different substrates. There is a good influence on biogenous element contents, height, root collar diameter, needle length and mass, root mass as well as physiological vitality of spruce seedlings. It was observed that the effect of nutrition depends also on the type of substrate.
