【 摘 要 】

The researches were carried out during 2018-2020, in the intensive cherry orchard of the varieties Kordia, Ferrovia, Regina, founded in the spring of 2017 at the company LLC “Clasprod-Fruct”, with the vegetative rootstock MaxMa 14, which later in the August was grafting in chip budding. In the spring of 2018, the rootstocks were cut to the grafted buds and during the vegetation period a vigorous annual stem was obtained in the form of a twig. For the study of various secondary technical operations and the rational branching of the leader, in the spring of 2019 an experiment was organized with the following gradation: 1. Trees trained as slender spindle improved system (control); 2. Extirpation of 4-5 axillary buds from top to bottom of the leader while keeping a bud intact. 3. Incisions above the buds. It was established that, when forming cherry crowns, of various varieties, grafted on the MaxMa 14 rootstock, in chip budding, it is reasonable to intervene on the buds on the leader through transverse incisions, when the buds begin to turn green. To increase the branching potential of the incisions made, the place exposed to cutting should be treated with the Progerbalin LG growth regulator (1.8% GA4+7 + 1.8% 6-BA), in the ratio one part of the product to eight-ten parts of latex paint
