熊蜂和蜜蜂为塑料大棚西瓜授粉对比试验 总被引:3,自引:0,他引:3
熊蜂和蜜蜂为塑料大棚西瓜授粉试验得出,熊蜂授粉比蜜蜂授粉的平均单瓜重较重,差异不显著(P>0.05);单位面积产量较多,差异不显著(P>0.05);瓜型更周正,差异显著(P<0.05);VC含量较高,增加0.14%;总糖较高,增加2.22%;糖酸比较高,增加2.23%;可溶性固形物较低,降低2.04%;硝酸盐相同;说明熊蜂授粉比蜜蜂授粉产量略高,瓜较重,外观较好,VC含量较高,糖含量较高,口感相差不大,均可达到有机食品标准。证实了熊蜂授粉技术可以代替蜜蜂授粉技术。 相似文献

根据2020年对山西省临猗县樱桃种植户调研数据,运用成本收益法研究樱桃种植户不同授粉方式下的成本收益情况,并进行比较分析。结果表明:樱桃生产过程中,底肥和追肥的投入占总成本的比重最大,同时人工成本也是农业生产过程的重要投入因素。不同授粉方式下农户的成本收益存在明显差异,每667m2樱桃的净收益由小到大顺序为:自然授粉<人工授粉<蜜蜂授粉<蜜蜂+人工授粉。因极端天气,蜂群无法活动时,采用蜜蜂+人工授粉的方式,可以提高果实品质和耐储性,降低果实裂果率和畸形率。此外,分析了影响农户成本收益的因素,进一步提出加快新型职业农民培育、加大蜜蜂授粉推广和宣传、针对农民防冻、防灾等问题出台相关政策等对策建议。 相似文献

本研究以腾冲红花油茶为研究对象,对其分别进行人工授粉、东方蜜蜂自由式授粉、东方蜜蜂强制性授粉处理,以期为提高腾冲红花油茶的产量提供重要依据。结果表明东方蜜蜂自由式授粉油茶座果率为30.3%,与人工授粉和强制性授粉差异不显著;结实率达24.6%,极显著高于人工授粉和强制性授粉,分别提高了10.6%和15.2%;自由式授粉油茶平均每株鲜果重为4.16kg,极显著高于人工授粉和中蜂强制性授粉;平均每株鲜籽重为1087.7g,显著高于人工授粉和中蜂强制性授粉。因此,中蜂自由式授粉是提高油茶产量的一项有效措施。 相似文献

The European honey bee (Apis mellifera) has the unusual status of being an inherently wild species from which a natural foodstuff (honey) is derived by manipulating its behaviour to deposit this in man-made wooden frames. Bees also produce propolis and Royal Jelly which can be harvested but their most important effect is one not immediately obvious as an economic product: that of pollination. Bee diseases are predominantly infectious and parasitic conditions accentuated by the close confinement in which they congregate, either in man-made hives or in colonies in a natural cavity. Treatment or at least control of some of these conditions can be attempted. In some cases natural bee behavioural traits limit the effect of the disease while in others, such as the notifiable disease American foulbrood, destruction of the colony is the only method of control. The mite Varroa jacobsoni can be controlled by the synthetic pyrethroids flumethrin and tau-fluvalinate. The introduction of these products has heightened veterinary interest in this important invertebrate species. 相似文献

温室内果菜类蔬菜缺乏昆虫授粉,产量低。笔者曾多次利用蜜蜂为温室内单性能结实的黄瓜“长春密刺”品种,荷兰引种的西红柿品种以及苦瓜、冬瓜和辣椒授粉,试验表明:其座果率、产量和质量比无蜂对照区都有明显提高。温室内西红柿利用蜜蜂授粉可代替已被淘汰的喷施2,4─D生长素的效果。 相似文献

Microsporidiosis caused by infection with Nosema apis or Nosema ceranae has become one of the most widespread diseases of honey bees and can cause important economic losses for beekeepers. Honey can be contaminated by spores of both species and it has been reported as a suitable matrix to study the field prevalence of other honey bee sporulated pathogens. Historical honey sample collections from the CAR laboratory (Centro Apícola Regional) were analyzed by PCR to identify the earliest instance of emergence, and to determine whether the presence of Nosema spp. in honey was linked to the spread of these microsporidia in honey bee apiaries. A total of 240 frozen honey samples were analyzed by PCR and the results compared with rates of Nosema spp. infection in worker bee samples from different years and geographical areas. The presence of Nosema spp. in hive-stored honey from naturally infected honey bee colonies (from an experimental apiary) was also monitored, and although collected honey bees resulted in a more suitable sample to study the presence of microsporidian parasites in the colonies, a high probability of finding Nosema spp. in their hive-stored honey was observed. The first honey sample in which N. ceranae was detected dates back to the year 2000. In subsequent years, the number of samples containing N. ceranae tended to increase, as did the detection of Nosema spp. in adult worker bees. The presence of N. ceranae as early as 2000, long before generalized bee depopulation and colony losses in 2004 may be consistent with a long incubation period for nosemosis type C or related with other unknown factors. The current prevalence of nosemosis, primarily due to N. ceranae, has reached epidemic levels in Spain as confirmed by the analysis of worker honey bees and commercial honey. 相似文献
