In the master‘s task there is examined the spurce, touched dy nucleus rot, uotspread in places of vegetation and i nage of types.
The task of the object is VĮ Sakiu forest enterprise‘s deforestations.
The aims of the task are:
1. the outspread regularities of spurce, touched by nucleus rot.
2. the economical losing due to tha spurce, tuoched by nucleus rot.
3. wind in-service damage in Sakiu forest deforestations.
The methods of the task are:
-the outspread regularities of spurce, touched by nucleus rot, to the sorts of deforestations in VI – IX centuries. The grow in Lb, Lc, Ld, Nc and Uc places of vegetation. The original informatikon is collected from 15 deforestations, and there are measured 1331 spruce,.
- economical losing due to the spruce, touched by nucleus rot. The actual price of wood was counted for every deforestation. This price was compared with one, which we goti f all trees would be unbroken.
Results of work- it was determined that the spread of rot depends on the age of the arboretum and the diameter of woods. The healthiest part of the arboretum consist of woods of medium diameter. As the age of arboretum increases, the demaget caused by rot also increases. Among the 70 - 80 year old arboretums there are about 27 – 39 percent of rot damaget firs. Because of this scortcoming about 35 percent of deals are rated as of the third category.Further raising of 70 year old fir forests in the lost of Lc and Ld is not useful. The variation of income...
