Pollination technique of Wall Bee

Get ready to seal the box and put it in the right place in the orchard. Then the bee cocoon is released 7-10 days before the fruit tree blossoms, and the number of bee cocoons generally released should depend on the different conditions of the orchard. Then do a good job in the basic management of water disasters and the prevention and control of natural enemies, so that the wall wasps can be pollinated. Take back the box 10 days after adult pollination, take out the nest tube and hang it in a gauze bag and keep it in a ventilated and cool room.

When should the bees be released?

After the bee cocoon is in the field, the adult bee bites the cocoon one after another, and it can only come out in 7-10 days. Therefore, it is necessary to release the bee cocoon 7-10 days before the fruit tree blossoms in order to make the activity of the wall bee coincide with the flowering period of the fruit tree and achieve the purpose of pollinating the fruit tree. If you raise the temperature of the refrigerator from 0-5 ℃ to 8: 10 ℃ ahead of time, and then put it into the field after 2-3 days, the cocoon emergence time can be shortened. In case the adult bees have all broken seedlings and come out of the bee before release, they should be released at the first flowering of the fruit tree. The release time is between 20:00 and 22:00, which can reduce the flying loss of the bees due to alarm. Must not release the bee cocoon after the fruit tree blossoms, when the wall bee breaks the cocoon, the peak flowering period of the fruit tree has passed, it can not play the role of pollination, but also reduce the number of wall bee reproduction. If possible, artificial cocoon peeling can be considered to release the wall wasp, so that its out-of-room time coincides with the florescence.

In a single orchard of fruit trees, cocoons are placed 7-8 days before flowering, and cocoons stored at 4 ℃ should be placed in 7-8 ℃ 15 days before flowering, so that a large number of bees pollinate when the fruit trees blossom. The apple orchard releases bees when the central flower is about 40% blooming, usually for 12-15 days. When a variety of fruit trees are mixed in the orchard, the flowering period is long, and the bees can be released twice, such as the first time in the apricot blossom and the second in the early flowering stage of pear trees.

The above is the introduction of wall bee pollination technology, I hope it will be helpful to you.
