Biometric parameters of Quercus robur L. seedlings with closed root system, depending on the mode of cultivation
Journal Title: Лісівництво і агролісомеліорація - Year 2012, Vol 121, Issue
Abstract
The investigations of growing oak seedlings with closed root system were carried out on the watered open area of greenhouses of Danilovskiy Experimental State Forest Enterprise of Ukrainian Research Institute of Forestry & Forest Melioration in 2011. Oak seedlings were grown in containers of spunbonded materials. For seedlings growth intensification we used such preparations as ammonium nitrate phosphate fertilizer (NPK (17:17:17)), organic-mineral fertilizer "Agrolife", potassium humate, microbial preparation "Baikal EM-1" and growth regulator "Fumar". The addition of peat and manure in substrate promoted an increase in heights, root collar diameters and weights of oak seedlings. "Air trimming" of oak seedlings roots had a positive effect on powerful and fibrous root system forming.
