REPRODUCTION OF ROOTSTOCKS OF FRUIT CROPS AND GROWING OF SEEDLINGS IN THE NATIONAL PARK “BUZULUKSKY BOR” ^{[№ 3 ' 2018]}
In the conditions of the National Park “Buzuluksky Bor” the possibility of growing rootstocks and seedlings of fruit crops was studied. A characteristic feature of sandy sod-podboryh soils of boron is their low fertility. They are characterized by weak podzolization, light loamy, carbonate. Sandy soils during the snowless period are freezing deep, while a sharp decrease in the temperature of the upper horizon to critical values is observed. In these conditions, in the queen cell of clonal stocks, the freezing of the head of the bush and a decrease in the yield of the layers are noted. In the nursery on poor soils, despite a high rooting of the rootstocks, a weak development is observed, which negatively affects the yield of seedlings and their quality. Despite the negative consequences, it is possible to grow high-quality planting material by applying organic fertilizers, increasing agricultural technology and selecting the most adapted forms.
