Abstract
The article provides data on the assessment of the state of broad-leaved forest crops created during the reconstruction of low-value forest stands in the forest fund. The effectiveness of various methods of reconstruction of measures depending on the share of broad-leaved species in the composition of forest crops is analyzed. It was found that during the period 2006–2018 reconstruction was carried out on an area of 3628 hectares in the Republic of Belarus using corridor (69 %), curtin-group (22 %) and continuous (9 %) methods. It is shown that the average survival rate of forest crops in the continuous reconstruction method was 84, corridor — 71 %, and preservation, respectively, — 61 and 63 %. The sub-topological forest crops created during the curtin-group reconstruction had an unsatisfactory condition (average survival and preservation — 40 %). It is recommended when creating broadleaf forest crops during the reconstruction of low-value forest stands to take into account their age, composition, forest growing conditions, as well as the biogroup placement of plantings, which ensures faster closing of crops in rows, and contributes to their favorable growth and formation, and to create an optimal width of corridors 4...6 meters, which will ensure uniform and sufficient distribution of light in forest crops.
