ASSESSMENT OF THE STATE AND RESTORATION OF BIOLOGICAL RESOURCES OF SCOTS PINE (PINUS SILVESTRIS L.) IN THE SOUTH OF THE CENTRAL RUSSIAN UPLAND

Abstract

The paper deals with an assessment of the current state and prospects for the creation of artificial forest plantations based on Pinus silvestris L. to increase the bio resource potential of the south of the Central Russian Upland. There have been tested and methodically substantiated various methods of creating long-term forest plantations based on Pinus silvestris L. by improving the methods of sowing seeds. Evaluation of the effectiveness of various methods of sowing pine has shown that more guaranteed and uniform seedlings and further development of seedlings provide sowing with cones. Having an equal number of seed holes when sowing with seeds and cones, it can be stated that the number of holes in which seedlings appeared during sowing with cones is 56.8% higher, the survival rate of seedlings is 34.6% higher, the number of seedlings is 25% higher, and the number plants per hole – by 50%. Sowing with cones is economically more profitable-no need to engage in costly threshing of seeds; cones are easier to plant during mass plantings in the process of laying artificial forest plantations; cones have a high hygroscopicity, the seeds are constantly in a moist state and germinate well, regardless of the conditions of soil and air moisture.
