Knowledge Title: Beekeeping Weather
Other Title: apiculture meteorology
An aspect of agricultural meteorology. The relationship between meteorological conditions and beekeeping and its change severance laws are mainly studied, including the influence of meteorological conditions on the growth, flowering and honeying of honey-derived plants, as well as on the individual growth of bees, group activity and the yield and quality of bee products. Because bees are particularly sensitive to meteorological elements, changes in the weather can often be predicted based on bees entering and leaving the hive.
The optimum temperature of honey-derived plant honey is generally 16 to 25 degrees C, and the relative humidity is 60 to 80%. Rain before flowering, flowering every 6 or 7 days there is light rain or moderate rain, after the rain sunny, warm, then nectar secretion is particularly rich. Canola, ziyunying, lychee and other flowering period in the rainy season when the yield of honey is unstable; Honey-derived plants in northwest China, in the summer and autumn in the event of drought, will affect the production of honey, king pulp; In the buckwheat flowering period, such as Gansu and other places blowing southeast wind, Inner Mongolia, Liaoning and other places blowing northwest wind, the amount of honey will be reduced or not nectar;
Bees are warm animals, and their body temperature varies with the temperature of the outside world. The individual safety critical temperature of medium bee and Italian bee is 10 degrees C and 13 degrees C respectively. The temperature is gradually frozen when the temperature is below the above measure, and the honey harvesting activity is basically stopped when the temperature is above 40 degrees C. The most flight-friendly temperature is 20 to 30 degrees Celsius. Bees can rely on honey and increased activity to generate heat, and they can lower the temperature in the nest by picking water and fanning. In the season of suitable activity, the temperature in the hive is maintained at about 34 to 35 degrees C, which is beneficial to the bees to cultivate young bees, wax, spleen and honey, and the high or low temperature will affect the normal development of young bees. When there are no young bees in the nest, the temperature change range should be between 14 and 32 degrees C. In winter, when the bee king stops laying eggs, the bee population is in a semi-stung state, the periphery of the bee group is generally maintained at about 7 degrees C, the central temperature is usually between 24 to 30 degrees C. As the external temperature rises, the bee mass expands, and the temperature decreases and the bee group shrinks.
Humidity is also closely related to the growth and activity of bees. High humidity, nectar is not easy to concentrate, low humidity, but due to lack of water and seriously affect the growth and development of eggs, larvae and crickets. The suitable relative humidity in the pyrethroid box is 35 to 45%. The optimum relative humidity for indoor wintering is 75-80%. The air is too dry to cause honey storage in the nest to lose water crystals, and bees cannot feed. In addition, light stimulates bees to attend. Weather such as suddenly from sunny to rain, bees will stop picking honey before the wind and rain, hurried back to the nest, temperament has become violent. Windless or breezy weather is suitable for bees flying. Spontaneous flightise is stopped when the wind speed exceeds 4.2 m/s and cannot be sustained at wind speeds of 6.7 m/s.
