夏季 蜜蜂养殖 关键措施
2024/8/14
防暑降温。蜂场要选择空气流通，有树荫的地方，或在蜂箱上覆盖草帘。天气过热时，可在箱外洒些冷水，并饲喂凉开水。对拥挤的蜂群，要提前做好增加蜂箱的准备，以增加空巢脾和巢础框，有利于青年蜂生产王浆。
油茶是重要木本油料植物,油茶产业是维护国家粮油安全的新兴力量,因花粉限制原因其出现了低产低效瓶颈问题,授粉是缓解该问题的根本途径。基于油茶为有毒蜜源植物,油茶林下养蜂技术要求高,本研究综述了油茶的粉蜜特性、引起家养蜂中毒的主要成份、家养蜂授粉预防中毒技术;探讨了家养蜂油茶授粉研究重点方向,旨在为生产中利用家养蜂油茶授粉提供科学依据。
为了促使产卵迟的蜂群尽快育子，可从已产卵的蜂群中抽出卵虫脾加入到未产卵的蜂群，这既能充分利用未产卵蜂群的哺育力，又能刺激蜂王开始产卵。
天然蜂粮生产技术研究与应用
蜂花粉 蜂粮 蜂粮生产器 营养成分
2017/11/9
蜂粮是蜂群中幼虫和幼蜂的食物，也是幼虫发育过程中的全价营养来源，同时也是供人类食用的蜂产品，其开发利用前景广阔，但目前因生产技术的制约导致不能市场化。本论文旨在研究如何快速生产优质的天然蜂粮，为天然蜂粮的机械化生产提供技术支撑。【方法】根据蜜蜂贮粉生物学原理设计一种能快速生产天然蜂粮的装置——天然蜂粮生产器，包括贮粮器和脱粮器，并以西方蜜蜂(Apis mellifera)为试验材料，研究天然蜂粮生...
利用RNA seq技术对中华蜜蜂（Apis cerana cerana，简称中蜂）幼虫肠道参考转录组进行de novo组装，并进行功能及代谢通路注释，进而利用该转录组数据进行中蜂幼虫的SSR分子标记鉴定。【方法】实验室条件下饲养中蜂幼虫，将纯化的蜜蜂球囊菌（Ascosphaera apis，简称球囊菌）孢子饲喂3日龄幼虫，剖取4、5和6日龄幼虫肠道，液氮速冻。将健康幼虫肠道与感染球囊菌的幼虫肠道同...
