FORMATION OF THE AGROFORESTRY SYSTEMS IN THE KURSK DISTRICT, KURSK REGION
In forest-agrarian landscapes, systems of protective stands are formed taking into account zonal attributes. The use of fast-growing species for forest reclamation in the conditions of the Kursk region is a common practice. Pure crops from balsamic, pyramidal, poplar, hanging birch 7.5-12.0 m wide at the age of 17-18 are represented by a blown, openwork-blown and openwork structure with a high forestry-reclamation estimate. With the joint growth of balsamic poplar with birch sagging at the age of 17 years, the birch sagging in the composition occupies 2.3 units. Poplar is superior in biometric growth indicators to birch by 3.7-14.6%. Fast-growing breeds are graded according to class Ia boniteta. Artificial linear shelterbelts, changing the microclimate in the protected areas of the fields, contribute to increasing the biological yield of crops. Among the forest belts of the blown structure, the yield increase for winter wheat is 5.4 c/ ha (17.9%), from the influence of plantings of the openwork structure, the increase is 4.2 c/ha (14.3%), of dense construction - 3.1 c/ha (10.5%). The range of active reclamation influence extends up to 12-15H (heights) of the stands. The introduction of fast-growing rocks in protective stands allows you to more fully obtain the reclamation effect in time and on the protected area.
