在设施草莓田间释放熊蜂,通过观察了解熊蜂的活动行为和活动习性,通过调查了解熊蜂活动设施环境条件、授粉对花期的选择和授粉效果。结果表明,熊蜂授粉活动时设施温度需要持续保持在12~30°C之间,相对湿度保持在50%~90%之间;熊蜂对花期具有选择性,每天访早期花平均在50%以上;在恶劣天气或者草莓突然的花开情况下,授粉率低于90%,正常天气情况下,熊蜂授粉率均在90%以上。
The Bumblebees were released in the field of strawberry plantations. By observing the behavior and activity of the bumblebees, the environmental conditions of the bumblebees were surveyed, the selection of pollination and pollination were studied. The results showed that the temperature of the facilities need to be kept between 12 and 30 ° C while the relative humidity should be between 50% and 90%. The bumblebee was selective for the flowering stage and averaged more than 50% Pollination rates are less than 90% for inclement weather or sudden blossoms of strawberries, and the pollinating rate of bumble bees is above 90% under normal weather conditions.
