异花授粉的作物在花期放峰,能增加授粉授精率,提高产量.但是不良气候下蜜蜂采蜜少,为作物授粉的效果也差.人工辅助授粉能部份克服不良气候对作物授粉授精的影响,提高产量.但是由于获得花粉数量少、花工多,影响了授粉技术在生产上大面积推广.为寻找获得大量粉源的办法,笔者四年来,在漳浦县荔枝龙眼产区多点蜂群中,采集荔枝,龙眼新鲜的蜜蜂花粉团进行花粉发芽率和贮存力的试验,在室温20℃、2%琼胶、7%葡萄糖培养剂培养三小时,显微镜观察,乌叶荔枝蜜蜂花粉团花粉发芽率69.83%,而同期鲜花花粉发芽率只有69.23%.在室温20℃于干燥器中贮存十天,花粉团发芽率还保持29.57%;龙眼蜜蜂花粉团用同样办法试验,花粉团发芽率高达90.6%,干燥器中贮存十天,花粉团发芽率还保持64.1%.
Cross-pollination of the crops in the flowering peak, can increase the pollination and fertilization rate, increase production.But under adverse climate honey bee pollen, the effect of poor pollination for crops.Artificial pollination can partially overcome the bad climate of the crop pollination and insemination Influence, improve yield.However, due to the small number of pollen, flower workers and more, affecting the pollination technology in the production of large-scale promotion.In order to find ways to obtain a large number of sources of powder, the author four years, in Longhua County, In the bee colony, the litchi and longan fresh bee pollen cluster were collected to test the pollen germination rate and storage ability. The cells were cultured at 20 ℃, 2% agar and 7% glucose for three hours at room temperature. Microscope, Pollen germination rate of 69.83%, while the same period the pollen germination rate of flowers was only 69.23% at room temperature 20 ℃ in the dryer for 10 days, the pollen germination rate remained 29.57%; longan honey bee pollen group using the same method of testing, pollen germination The rate of up to 90.6%, dryer for 10 days, the pollen germination rate remained at 64.1%.
