Although practice has proved that the orchard is very effective in pollinating the wall bees, some fruit farmers have also used the bees to release the bees and lay their nests. However, at the end of the flowering period, it is found that the fruit setting rate is low and the fruit set is uneven. Happening. There are roughly the following reasons:
Release the bee too late
If the wall bee is released too late, it will cause the wall bee to not meet the flowering period and the flowering period, resulting in unsuccessful pollination. Because it takes 5-7 days to release the bee after the wall bee sting is released, the bee-keeping time should be advanced accordingly.
Not enough bees
If the pollination tree is not properly configured, the bees that put the bee in order to increase the fruit setting rate can put 150-200 bees per acre. If the objective conditions of the orchard are better, then put 100 bees per acre.
Nest box layout is not reasonable
Insufficient or excessively focused honeycombs can also result in poor pollination. It is generally considered that the distance between the nest boxes is preferably 20 to 30 meters, and a small nest box should be set every 20 meters at the edge of the orchard.
Spraying pesticides before flowering
Near the flowers before the bees are sprayed with highly toxic or repellent pesticides. Most of the wall bees are poisoned or driven away, leaving the bees to fail. In order to protect wall bees and other insects that help pollinate fruit trees and increase fruit setting rate, whether or not to lay bees, do not spray pesticides as far as possible from 7 to 10 days before flowering.
