Produkcija i kvalitet livadskih asocijacija u šumskim lovištima Srbije

Abstract

Determinacija livadskih asocijacija utvrđena je na tri lokaliteta: ograđeni deo lovišta 'Posavsko lovište Karakuša' (Šumsko gazdinstvo Sremska Mitrovica), ograđeno uzgajalište 'Miloševa voda' (Sokolovica) i ograđeno uzgajalište 'Lomnička reka' (Veliki Jastrebac). Fitocenološkim snimcima je utvrđena brojnost i pokrovnost, a u uzorcima je utvrđena zastupljenost biljnih vrsta, na osnovu čega je određena pripadnost biljnim zajednicama. U determinisanim asocijacijama utvrđeno je procentualno učešće vrsta trava i leguminoza visokog, osrednjeg i lošeg kvaliteta, kao i vrsta ostalih familija, uslovno korisne, loše, bezvredne, škodljive i slabo otrovne. Na prvom lokalitetu utvrđene su asocijacije: Agrostio-Juncetum effusi Cinc. 1959., Trifolio-Agrostietum stoloniferae LJ. Mark. 1973., Agrostietum vulgaris Z.Pavl. 1955. sensu lato. Na drugom lokalitetu, na obe livade utvrđena je asocijacija Festuco-Agrostietum Horv. (1952) 1982.em Trinajest. 1972., dok je na trećem lokalitetu utvrđena asocijacija Agrostio-Festucetum valesiacae Gajić 1961. U ispitivanim asocijacijama utvrđena je produkcija zelene mase i suve materije, kao i osnovni parametri kvaliteta travne mase (sirovi proteini, sirova celuloza, sirove masti, BEM i mineralne materije).

Determination of meadow associations was done on three locations: enclosed section of the hunting ground 'Posavsko lovište Karakuša' (Forest holding Sremska Mitrovica), enclosed breeding ground i.e. area 'Miloševa voda' (Sokolovica) and enclosed breeding ground 'Lomnička reka' (Veliki Jastrebac). Phytocenological records were used to determine number and cover, and in samples the presence of plant species was determined and based on this analysis to which plant associations they belong. In determined associations the share in percentages of grass and leguminous species of high, medium and poor quality was determined, as well as species of other families, conditionally useful, bad, worthless, harmful and slightly poisonous. On the first location the following associations were established: Agrostio-Juncetum effusi Cinc. 1959., Trifolio-Agrostietum stoloniferae LJ. Mark. 1973., Agrostietum vulgaris Z. Pavl. 1955. sensu lato. On the second location, on both meadows, the association Festuco-Agrostietum Horv. (1952) 1982. em Trinajest. 1972. was established, whereas on the third location, association Agrostio-Festucetum vallesiacae Gajić 1961 was established. In investigated associations, the production of green mass and dry matter was established, as well as main parameters of the quality of grass mass (crude proteins, crude fibre, crude lipids, NFE and mineral matters).
