深入研究的结果表明,采访花的蜜蜂数是直接与14到21℃之间的气温(树枝离地高度)有关;温度每上升4度,蜜蜂数增加4倍。云层增加或风速增大会减少蜜蜂数。不同高度树枝之间的蜜蜂数有明显的差别;离地3—5米的树枝蜜蜂的数量最大。树枝的方向没有什么影响。蜜蜂采集活动高峰在中午11点到12点之间,以及下午2点30分到3点30分之间。
In-depth study showed that the number of bees interviewed was directly related to the temperature between 14 and 21 ℃ (the height of the branches off the ground); for every 4 degrees temperature rise, the number of bees increased 4-fold. Increased cloud or wind speed will reduce the number of bees. The number of bees between branches at different heights is obviously different; the number of bees with branches 3-5 meters away is the largest. The direction of the branches has no effect. Bees gather peak activity between 11 noon and 12 pm, and between 2.30 pm and 3.30 pm.
