For the proper organization and effective use of the honey base of beekeeping, it is important to assess the honey productivity of the area. Honey plants are a source of food for bees and commercial products of apiaries. The nectar collected on them is processed by bee colonies into honey, and a stock of bee bread is created from flower pollen. When assessing the area in a melliferous relation and compiling a honey balance of an apiary, it is necessary: take into account the species composition of honey plants in the area of productive flight of apiary bees; identify the area occupied by honey plants; calculate the honey reserve of the area; determine the number of bee colonies that can be provided with honey in a given apiary. Features of the app: Apiaries - creation of apiaries and showing their locations on the map; - displaying a list of fields; - recording the weight of control hives; - recording weather data; - adding photos. Fields - creation of fields on a map of the area; - determination of productive areas of the field, for each apiary separately; - distribution of fields into groups. Floral sources - creation of honey plants; - making the sequence of flowering. The beginning of flowering of melliferous plants depends on the latitude and longitude of the area, growing conditions, as well as meteorological indicators of a given year, but the sequence of flowering of honey plants for all areas is more or less the same. Synchronization The app allows you to synchronize data on all devices: - automatic synchronization between a computer, phone or tablet; - start work on one device and continue on another.
