Obnova travne ruše na prezimovališču za ovce

Stanič, Ana Marija (author), Vidrih, Matej (mentor)

Skrb za obnovo poškodovane ruše po zaključku prezimovanja živali na prostem je pomembno opravilo, saj se lahko zgodi, da se nam zaradi zanemarjanja nege v njo naselijo nezaželene zelnate rastline. Zato smo spomladi 2017 na prezimovališču za ovce na Laboratorijskem polju Biotehniške fakultete izvedli poskus obnove poškodovane ruša z namenom določiti najbolj primerno krmno vrsto za obnovo. Poskus je potekal na mestih, kjer so živali dobivale krmo, so ležale in se napajale. Izbrana mesta v ruši so bila različno poškodovana (krmišče, ležišče in napajališče) zaradi gaženja oziroma so bila pokrita z izjedjo oziroma ostanki krme in je od prvotne ruše ostalo premalo poganjkov za naravno obraščanje. Prav tako smo v proučevanje vključili 4 različne krmne rastline (navadna pasja trava, trpežna ljuljka, trstikasta bilnica in bela detelja) in 3 termine setve (1. februar, 1. marec in 3. april). Setev je bila opravljena ročno v polovičnem odmerku od priporočene setvene norme v predhodno le z grabljami z(mešano) slamo z zemljo. Najboljši vznik (med 65 in 75 %) je bil ocenjen pri beli detelji in to tako med lokacijami kot tudi roki setve. V povprečju je bil najboljši vznik sejanih vrst na krmišču. Navadna pasja trava je dosegla najboljšo pokrovnost na ležišču, medtem ko je na krmišču tla najbolje pokrila trpežna ljuljka. Višina rastlin po 45 dneh rasti je bila najnižja na napajališču in tudi razlike med vsemi štirimi vrstami so bile tu najmanjše. Največ pridelka suhe snovi (4,82 t/ha) smo na krmišču izmerili pri pasji travi, ko je bila sejana v začetku aprila. Navadna pasja trava in trpežna ljuljka sta v poskusu obnove ruše prezimovališča dosegle podobne rezultate.

• Title: Sward renovation of sheep outwintering camping site

Abstract

The renovation of damaged sward on outwintering camping site is an important measure of pasture management as neglecting the sward care might lead to sward infestation with unwanted plants. In spring 2017 we established a field experiment on the outwintering camping site for sheep at the Biotechnical faculty with the intention of selecting the best forage plant for renovating the damaged sward. The trial was conducted on micro sites where animals get feed, they rest or they get water. The sward of the selected sites was differently damaged due to trampling intensity or the sward was covered with forage residues but not much tillers were left for sward to regenerate in spring. Also included were 4 different forage species (Dactylis glomerata, Festuca arundinacea, Lolium perenne, Trifolium repens) and three seeding dates (February 1st, March 1st and April 3rd). Seeding was performed by hand and half of the recommended seeding rate was used. White clover had the highest estimated emergence rate (between 65 and 75 %) between locations and seeding dates. On average the highest estimated emergence rate was found on feeding site. D. glomerata gained the best cover on the bedding site. Meanwhile L. perenne cover was highest on the feeding site. Plant height after 45 days of growth was the lowest on watering site and also differences in plant height between all four species were the lowest. The best yielding species (4.82 t/ha) was D. glomerata sown at the beginning of April. D. glomerata and L. perenne achieved similar results when testing them in a trial of sward renovation on outwintering camping site.
