Growth and weight annuals oak seedlings grown in containers with different composition of substrates

O.I. Lyalin


Explored and described the basic values of biometric indicators annual oak seedlings grown in containers with different composition of the substrate. The influence of substrate components of the container on the diameter and height of seedlings, length of stems and roots, their mass. The research was conducted in SE "Chugueva-Babchanske LH" Kharkiv Forestry and Hunting Administration.

The aim of the study was to investigate the influence of the composition of the substrate container height and diameter of the common oak seedlings stalks (Quercus robur L.), their weight and the length of the root system as a whole and its parts in particular.

Research methods: biometrics – to assess the effectiveness of processing methods of cultivation of seedlings with closed root system, and mathematical and statistical – analysis of experimental data.

It was established that year old height and diameter oak seedlings was significantly higher than control and has the highest value in research options with the composition of the substrate Peat: soil – 1: 1 and Soil: humus, sawdust – 4: 4: 2. Average weight of aerial parts of seedlings of oak in the form of Peat ratio: soil – 1: 1 also exceeded most control. Share overground mass of leaves of oak seedlings was 44,0 % in the variants using peat substrate consisting greatest value of this index is defined for option Peat, soil – 1: 1 and in the form ternary substrate Soil: humus, sawdust – 5: 4: 1.
