V.Topić, L. Butorac, Z. Đurđević, B. Kekelić, G. Jelić: UTJECAJ TIPAKONTEJNERANARAST I RAZVOJ ...Šumarski list br. 3–4, CXXXIII (2009), 121-134 Five-year monitoring of plant development in the experimental plot showed that the afforestation method with common cypresses planted in the soil undermined with a ripper to 50 to 70 cm in depth gave better results than the classical method of afforestation in dug holes of 40 x 40 x 40 cm. Common cypress plants from polyethylene bags of 923 cm3 planted in the soil undermined with a ripper had an average height of 74.5 cm and maximal height of 181.0 cm. Those planted in dug holes reached a height of 54.5 cm and maximum height of 128.0 cm (Figures 9 and 10). Plants from B12 containers showed the smallest height increment. The average plant height in the soil undermined with a ripper was 48.4 cm and the maximal height was 101.0 cm, while that in dug holes was 38.4 cm to 76.0 cm. The above data show that common cypress is a very useful species for afforesting karst areas and establishing mixed cultures in particular, on condition that the soil is properly prepared for afforestation and only good quality planting stock used. This material includes two-year-old seedlings grown in larger volume containers (900 to 1000 cm3). Planting should be timely and expertly performed and obligatory tending treatments should be applied in the first several years after planting. |
