苏北地区越冬蜂的繁殖时间宜在9月中旬开始。太早,繁殖的越冬蜂在采集飞翔中损失大,对保存越冬蜂的实力不利;太迟,不但要多消耗饲料並因后期缺粉会造成越冬群势的下降。因此怎样繁殖好越冬蜂,以及怎样管理好越冬蜂至关重要。 一、越冬蜂的繁殖 1.调整群势。对弱群应补足6框以上的群势。淘汰老劣蜂王。双王群应补足8框以上的群势,对10框以下的蜂群应停止生产皇浆,使蜂群全力以赴投入到越冬蜂的繁殖中。同时对有螨害的蜂群应加紧用药治螨,使越冬蜂的螨害降到最低程度。在开始奖饲时加一次抗生素,以增加越冬蜂的抗病能力。
Northern Jiangsu bee breeding time should begin in mid-September. Too early, the breeding of wintering bees in the acquisition of flight loss, the strength of the preservation of wintering bees unfavorable; too late, not only to consume more feed and lack of powder due to post-winter decline will result in overwintering. So how to multiply good wintering bees, and how to manage the wintering bees is very important. First, the winter bee breeding 1. Adjust the group. The weak group should make up more than 6 boxes of group potential. Outdated old bad queen. Double Wang Qun should make up more than 8 boxes of the population, the bee population below 10 boxes should stop production of royal jelly, so that bees go all out into the winter bee breeding. At the same time the mites harm the bee colony should step up the use of drugs to cure mites, so that the mite damage overwintering bees to a minimum. Add antibiotics at the start of rewards to increase the disease resistance of wintering bees.
