СОСТОЯНИЕ ХВОЙНЫХ ИНТРОДУЦЕНТОВ В Г. НУР-СУЛТАНА

Abstract

The article presents observational data on the survival, preservation and growth of introduced tree species created in the interstrip spaces of the green zone of the city of Nur-Sultan. The greatest preservation is characterized by Siberian spruce (Piceaobovata Ledeb.) (76.8%) and blue spruce (Piceapungens Engelm.) (58,9%). Black spruce (Piceamariana Mill.) and Siberian larch (Larixsibirica Ledeb.) have a preservation rate of an average of 44.5%. The lowest survival rate and preservation (16.4%) is distinguished by Siberian fi r (Abiessibirica Ledeb.). When comparing the method of planting forest crops with planting the material with an open and closed root system, it was revealed that the survival ability and preservation of seedlings with ORS was slightly higher than that of seedlings with CRS. The average survival ability of seedlings with ORS was 58.1%, for seedlings with CRS – 53.7%. Plants height corresponds to the biological characteristics of woody species. The highest average height was for Piceamariana Mill (184.1 cm), the smallest average height was for Piceaengelmannii Parry ex Engelm (143.4 cm). The most acclimatized species of woody plants – Piceaobovata Ledeb., Piceapungens Engelm. and Piceamariana Mill – have been identifi ed. These trees have a high capacity for survival, stable growth and decorative effect. These coniferous plants can be used to create green areas of settlements in Kazakhstan, similar in soil and climatic conditions to the city of Nur-Sultan.
