油茶地蜂(Andrena carmellia Wu.)是一种重要的油茶授粉蜂,它广布于油茶产区;在老产区几乎都有蜂孔密度超过300—400个/米~2的密集分布区。据调查,油茶地蜂在晴朗气候条件下,每天可出洞采访3—5次(每天至少采访30朵),每次可携带花粉13万粒;经由地蜂类采访的油茶花,座果率可达70%以上。在油茶林内如果每树能有蜂5—10头(且分布均匀),就能初步满足油茶授粉的需要。油茶地蜂还能起深翻土地、改善土壤通透性和增加土壤肥力(排泄物)的作用。因此,在蜂群密集的地段,油茶的座果率显著高于无蜂或少蜂地段(见表1)。但由于该蜂蜂体弱小,自然扩散能力低,繁殖比较缓慢,在新油茶林内,特 Andrena carmellia Wu. Is an important Camellia pollination bee widely distributed in Camellia producing areas; almost all the old producing areas have a density of more than 300-400 cells / m ~ 2 dense distribution. According to the survey, Camellia bee under the sunny weather conditions, the hole can be interviewed 3-5 times a day (at least 30 daily interview), each time carrying pollen 130,000; Camellia flowers by the bee interview, fruit rate Up to 70%. In the tea tree if each tree can bee 5-10 head (and evenly distributed), we can initially meet the needs of Camellia pollination. Camellia bee can also play a deep turning the land, improve soil permeability and increase soil fertility (excrement) role. Therefore, the fruit-setting rate of Camellia oleifera was significantly higher in the swarms than in the no-bees or less-bees (Table 1). However, due to the bee is weak, natural diffusion capacity is low, reproduction is relatively slow, in the new Camellia forest, special
