Detailed Explanation of Key Techniques for High-Quality and High-Yield Bee Pollen

Selecting a good pollen source and placing bee colonies in favorable locations for pollen collection requires choosing the best nectar and pollen sources for placing bees whenever possible. Plants such as rapeseed, watermelon, corn, sunflower, and buckwheat not only allow for the collection of large amounts of pollen, but also yield pollen of high purity and superior quality.

Cultivating age-appropriate bee colonies: worker bees are the key to pollen collection, and strong foraging colonies must be actively cultivated to ensure increased pollen collection. Producing pollen, like producing honey, requires a large number of age-appropriate foraging bees. For this reason, 45 days before starting pollen production, a large number of age-appropriate foraging bees should be reared for pollen production. 15 days before pollen production or around the time of entering the pollen production site, extract some capped brood combs with young bees from strong colonies to supplement weak colonies, building weak colonies up to about 10 frames of bees. Bee colonies producing pollen are more efficient at medium colony strength during the proliferation period, unlike royal jelly and honey production where the stronger the colony the better. When a bee colony enters the proliferation period, the queen lays eggs vigorously, worker bees actively nurse the brood, the colony requires a large amount of pollen, and field bees are highly motivated to collect pollen. Under such conditions, with normal weather and abundant external pollen sources, colonies of more than 5 frames can produce pollen, and colonies with 8-10 frames of bee strength achieve ideal pollen yields.

Proper pollen removal methods: select appropriate pollen removal tools and improve the installation method of pollen traps. Choose pollen traps with different numbers of rows according to the number of worker bees, to solve the adverse consequences caused by crowding when bees enter the hive. For colonies of fewer than 10 frames, use two-row pollen traps; for those of more than 10 frames, use three-row pollen traps.

During the pollen production season, bees about to leave the hive @#@255@#@ circle around inside the entrance (blocked by the pollen trap), while bees returning with pollen crowd outside the entrance, affecting foraging trips, and because foraging bees gather inside the entrance, the whole colony becomes agitated, colony temperature rises accordingly, and bee aging accelerates. The improved method is to install the pollen trap 1 cm away from the front wall of the hive, creating a gap between the hive wall and the pollen trap. As a result, most outgoing bees fly out through the gap, while the vast majority of pollen-carrying bees returning to the hive enter through the pollen removal holes, increasing pollen removal by more than 15% and reducing pollen damage rate by 10%.

Timely replacement of the queen: eliminate old and inferior queens and replace them with new queens. Bees collect pollen mainly to feed larvae, and pollen production is related to the number of larvae in the colony. Therefore, colony reproduction should be promoted, ensuring a normal ratio of eggs, larvae, pupae, and bees, with larvae developing well. Young and middle-aged bees are more fond of collecting pollen than old bees, and the pollen loads they collect are larger; the more young and middle-aged bees there are, the higher the yield. Thus, eliminating old and inferior queens and using new queens is a very effective measure for pollen production. Because new queens have strong egg-laying capacity and there are more larvae, this can greatly stimulate the bees' enthusiasm for pollen collection.

Maintaining adequate feed: during pollen production, if the colony lacks honey or has insufficient honey stores, a large number of foraging bees will stop collecting pollen and instead search for and collect nectar. For this reason, sugar syrup should be fed to supplement the hive and fed in sufficient quantity; at the same time, pollen combs should be extracted from the colony and properly stored for use in feeding the colony when pollen is scarce, keeping the colony with insufficient pollen stores, only enough for feed, and providing stimulative feeding to stimulate the bees' enthusiasm for pollen collection.

Regular pollen harvesting: during a flowering period, pollen removal should begin when the colony's pollen intake slightly exceeds consumption. When the main nectar flow begins, pollen removal should end or be changed to extracting pollen combs. According to the flowering and pollen-shedding patterns of nectar and pollen source plants, install pollen traps at the hive entrance to intercept pollen loads for 2-3 hours and collect bee pollen. If conditions such as high humidity, abundant pollen, and poor nectar flow occur, some nectar source flowering periods allow all-day pollen removal, while others allow pollen removal only for a relatively short time; for example, corn only yields more pollen between 6:00 and 10:00. In seasons with abundant pollen sources that are also nectar flow periods, production times should be staggered. Before 11:00 each day is generally when bee colonies bring in large amounts of pollen; place pollen traps in front of the hive entrance to collect pollen, and remove the pollen traps after 11:00, producing honey at noon and in the afternoon. During the autumn sunflower and buckwheat flowering periods, when removing the pollen traps, pay attention to reducing the hive entrance to prevent robbing. When there is abundant external pollen and little nectar and the colony strength is weak, it is not necessary to install and remove the pollen trap every day; pollen can be collected exclusively. However, a small amount of pollen must be supplied to the colony so as not to affect normal colony reproduction.

During a single flowering period, if honey, royal jelly, and pollen are harvested together, pollen removal should be carried out before 9:00, with the pollen trap installed and removed at appropriate times before and after pollen removal, royal jelly produced in the afternoon, and honey produced in between. Exclusive pollen production should be carried out when colony strength is still weak or when there is abundant external pollen and little nectar.
