Productivity of Forest Plantation Crops = Продуктивность лесных плантационных насажденийProductivity of Forest Plantation Crops = Продуктивность лесных плантационных насаждений Reduction of time for commercial wood cultivation and increasing the
productivity of plantations is an urgent direction of scientific research considering supply
of forest resources in the country and the growing need for timber. One of the ways of
intensive forest reproduction is the creation of forest plantation crops. Plantation of forest
crops involves the cultivation of technically valuable tree species in a shorter period of
time. Our country has experience in the creation of forest plantation crops, but due to the
reorganization in the forest industry, many areas were left without proper care. However,
for 34 years research scientists at the Mytischi Branch of the Bauman Moscow State
Technical University (formerly Moscow State Forest University) have been systematically
monitoring the growth and development of spruce forest crops created in 1984 with
intermediate agricultural use between the rows. The method of creating test crops is
aimed at providing the most favorable conditions for growth and development of the main
tree species in the first years after planting, the use of the natural growth of plantations
during the entire period of crops cultivation, cost optimization for frequent silvicultural
care, obtaining stands with high economic and aesthetic properties, prevention of wood
defects. The article presents the technology of creating spruce crops, which is a distinctive
feature of this method. We analyzed changes in the diameters and heights of trees grown
by creating forest crops in the traditional way and with the use of intermediate agricultural
use between the rows. The reliability of differences in the average values of independent
samples was assessed, confirming the advantage of the spruce test crops. Their species
composition is 100 % spruce, the absolute taper of which is 2.13 times less than those
created by the traditional method. A higher probability of obtaining trunks with a volume
of more than 0.02 m3 by creating test crops has been established. The results of statistical
processing of experimental data indicate the prospects of the method of planting spruce
forest crops with intermediate agricultural use between the rows, which contributes to the
formation of high-quality stands.
