Preference of Pollinator for Nectar and Pollen Combination in Winter
In order to explore the relationship between pollinating behavior and the model plants with different nectar and pollen combinations, field survey method was employed to investigate the preference of pollinator for phanerogams with different nectar and pollen combinations in winter, including Brassica campestris(contains lots of nectar and appropriate pollen), Brassica alboglabra (contains lots of nectar and some pollen) and Vicia faba (contains a little nectar and plenty of pollen).Results:Pollinator significantly prefer to visit the oilseed rape (591±11.83) individuals/d than broad bean (127±1.90) individuals/d and cabbage mustard(180±2.53) individuals/d.Pollinators prefer oilseed rape to broad bean significantly.The peak visiting quantity and time in one day varied among the dominant pollinators.The peak visiting quantity of Apis cerana, hoverfly, Apis mellifera and housefly in one day were respectively (34±9.80) individuals, (14±0.56) individuals, (39±9.17) individuals and (12±1.34) individuals, the corresponding time emerged at 12:00~13:00, 12:00~13:00, 12:30~14:30 and 16:00~18:00 separately.The variation of peak visiting quantity and time was beneficial for decreasing the competition between pollinators so as to enhance the pollination rate of phanerogams.
