Abstract
This article presents the results of research on the study of some bioecological properties of honey-producing trees and shrubs. The flowering period of the main trees and shrubs is March-June and allows to obtain a high amount of honey. During the summer months, Lycium barbarum, Symphoricarpos albus, Sophora japonica species continue to bloom until autumn. According to the data, the growth rates of all trees and shrubs were at the level of demand. In particular, when growing linden trees in the spring, their height increased from 190.5 cm to 230.5 cm in autumn. That was, it grew by 40 cm during one vegetation. The Ligustrum bush had the highest growth rate, with seedlings planted in spring averaging 90 cm in height and 155.8 cm in autumn, with an annual growth rate of 65.8 cm. These indicators depicted that the conditions in the experimental fields were suitable for the growth of trees and shrubs.
Highlights
Beekeeping is one of the most productive areas in forestry
The longest-flowering species were Lycium barbarum (160 days), Symphoricarpus albus (120 days), Sophora japonica (100 days) that ensured the use of bees throughout the summer without relocation
Tilia cordata trees grew from 190.5 cm in spring to 230.5 cm in autumn
Summary
It is important to establish plantations of trees and shrubs that produce large amounts of nectar and long-flowering in the forestry area. Among the fruit trees and shrubs, the species, which belong to the family of rhinoceroses, serve as a source of food for the development and reproduction of bees in early spring [1,2]. In order to provide bees with nectar throughout the year, it is important to develop a scientific basis for the establishment of plantations of flowering trees and shrubs that alternate throughout the growing season [3, 6, 8]
