我国是世界蜂产品的来源和出口大国,养蜂扶贫更是我国乡镇振兴发展的重要举措,而中华蜜蜂是我国的土著蜂种,具有养殖风险小、投资少等特点,饲养数量较大,约占我国总蜂群数的1/3,因此中华蜜蜂养殖产业已成为延安地区基层产业发展的重要组成部分,在促进区域经济发展以及个人收入水平提升上发挥了重要作用。但是我国的养蜂人员还存在专业水平不高、养殖模式落后等诸多问题,再加上气候的变化导致的中华蜜蜂数量不断下降,给当前的中华蜜蜂养殖产业造成了较大的打击,而且蜂蜜产品质量也有所下降,不利于我国蜜产品的对外贸易。所以,要加强对中华蜜蜂养殖技术的研究工作,明确其养殖技术要点,以提高中华蜜蜂的养殖水平,保障蜂蜜产品的数量与质量。基于此,本文介绍了中华蜜蜂的养殖技术,供参考。 相似文献

《中国蜂业》2017,(4):50-52
蜂产业具有授粉服务、蜂产品市场供给、休闲旅游、传承蜜蜂文化、促进社会发展的多种功能。全面认识并不断开发蜂产业的多种功能,对推进现代蜂业建设、实现蜂产业的可持续发展意义重大。中国国内已经出现了发展授粉产业、发展规模化养蜂、发展山区中蜂养殖、建设蜜蜂文化园、举办蜜蜂文化节等蜂业发展模式。为促进中国多功能性蜂产业的发展,提出了实施蜜蜂授粉支持政策、研发养蜂生产管理新技术、发展贫困山区中蜂养殖、实现养蜂业与旅游业深度融合等建议。 相似文献

正一、示范区基本情况蜜蜂养殖是北京郊区(尤其是山区)比较主要和传统的养殖项目之一,门头沟地区蜜蜂养殖数量约3万群。多山是门头沟区显著的自然特点,全区总面积1455平方公里,山区占据98.5%,由于山区耕地少,支柱产业少,农民收入低,但是自然环境好,蜜源植物丰富,非常适宜发展蜜蜂养殖。为了更好的发展区域蜂业经济,将蜜蜂养殖这一投资小、见效快、无污染的生态环保型产业发展成为门头沟区的重点养殖业,使蜂业经济为北京生态涵养 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献
