Abstract

Nastopil je čas za premeno malodonosnih borovih gozdov na Krasu. Da bi ugotovili primernost drevesnih vrst, je bilo leta 2012 osnovanih 6 poskusnih ploskev v neposredni bližini Divače. Tri ploskve so bile osnovane na boljšem rastišču na ravnini, tri pa na slabšem na pobočju. Na vseh ploskvah so bile posajene naslednje drevesne vrste: navadni koprivovec (Celtis australis L.), graden (Quercus petraea (Matt.) Liebl.), navadna bukev (Fagus sylvatica L.), divja češnja (Prunus avium L.), navadni oreh (Juglans regia L.) ter gorski javor (Acer pseudoplatanus L.). Prve meritve so bile izvedene po prvi rastni sezoni leta 2013, ponovljene in razširjene pa so bile leta 2017 po štirih rastnih sezonah. Merili smo višino sadik, višinski prirastek, premer debla 5 cm nad tlemi in ocenili preživetje, vitalnost in kakovost. Poleg tega smo naredili analizo tal. Po ponovnem merjenju leta 2017 se je izkazalo, da je bil ob upoštevanju rastiščnih razmer uspeh preživetja sadik presenetljivo visok, saj je skupno preživelo kar 70 % posajenih sadik. Glede na vse merjene parametre se je do zdaj kot najuspešnejša pokazala divja češnja, najmanj pa navadna bukev. Kakovost rastišča je najbolj vplivala na uspeh pri gorskem javorju, saj je imel največjo razliko v deležu preživetja med rastiščema.

Secondary title:	Survival and quality of deciduous trees in experimental plantations near Divača
Secondary abstract:	The time has come for conversion of low productivity karst pine forests. In order to determine the suitability of tree species, 6 experimental plots were established in 2012 near Divača. Three plots were located in a more productive site on flat terrain and three on the less productive site on the slope. The following tree species were planted on all plots: Celtis australis L., Quercus petraea (Mattuschka) Liebl., Fagus sylvatica L., Prunus avium L., Juglans regia L. and Acer pseudoplatanus L. The first measurements were made in 2013 after first growing season. They were repeated and expanded in 2017 after four growing seasons since planting. The height of seedlings, increment, stem diameter 5 cm above the ground, vitality and quality were measured or estimated. In addition, a soil analysis has been made. After re-measuring in 2017, the success of survival of the seedlings was surprisingly high according to the site conditions, because 70 % of all planted seedlings survived. The most successful species so far was P. avium, while F. sylvatica was the least successful. Acer pseudoplatanus was the most susceptible to poor field conditions, as it had the largest difference in the survival rate between the plots.
