In addition to digging 50 m deep, 40 cm long, and 30 cm wide earth pits near the hive to provide moist soil, we must also pay attention to providing wall bees with plenty of pollen nectar to prevent nectar bees from siphoning after fruit trees have no honey. Foraging, flying to other places, resulting in reduced recovery. Because the time of wall bee activities is about 45 days, and the flowering period of fruit trees is relatively short, in order to increase the breeding coefficient of wall bees, near the hive can be planted with overwintering rapeseed, radish, and seedling cabbage in advance. The flowering is early and the flowering period is longer. Plants provide wall bees with honey pollen sources, supplementing the nutrients needed for their activities, so as to avoid the decrease in bee volume caused by the wall bees released. It is also possible to plant the wild vegetable Zhuge Cai (also known as the February Orchid, Cui Violet) in the early spring. Zhuge Cai gradually blooms from early April to late May. The flowering period lasts for 50 days, especially after May has been visited by all kinds of fruit trees. It can provide sufficient food for the wall bees released by this garden. Wall bees that attract other places come to feed and nest.
Raising vegetables from nests to increase wall bee recovery
The phone number 151*****753 Linyi readers to inquire: I do not know this year because of the weather or other reasons, pollen pollination rate for fruit trees is relatively low, what methods can improve?
