通过对淳安县威坪镇蚕桑产业现状的分析,认为威坪镇蚕桑产业下滑的主要原因一是蚕茧价格与蚕农期望值差距较大,蚕农的栽桑养蚕积极性不高;二是养蚕劳动力数量下降、体能变弱,蚕桑产业发展后劲不足;三是农村劳动力就业门路广且工价高,养蚕劳动力从养蚕行业转出;四是桑园培管粗放,桑叶和蚕茧的产质量变差等。针对这些问题,提出了加大现有桑园桑树品种更新力度,结合桑树品种更新集中连片发展消灭插花地;加大桑园土地流转力度,逐步培植养蚕大户;加强桑园基础培管,夯实桑园基础;推行"十天养蚕法"新模式,加强示范点建设;加强村级蚕桑技术服务队伍建设,提高养蚕整体技术水平;抓好蚕茧外部市场监督管理,保障蚕农利益;加强蚕桑保险,降低养蚕风险等助推威坪镇蚕桑产业发展的建议。 相似文献

<正> 蚕桑生产是我县多种经营的骨干项目,也是我县农村广大农民脱贫致富的主要家庭副业。党的十一届三中全会以来,在改革开放政策的推动下,全县蚕桑生产有了较大发展。为了加快实现我县第二个战略目标,我们决心以兴桑养蚕作为振兴略阳农村经济突破口,进一步加快蚕桑生产发展步伐。 相似文献

泾县养蚕历史悠久,全县21个乡镇乡乡养蚕,养蚕农户达2万多户,全县桑园面积约2333hm2,常年饲养5.5万张,产茧2500余t.蚕桑生产是该县农村的支柱产业,也是农民经济收入的主要来源之一.近几年由于受国际、国内市场诸多因素影响,茧价不断下滑. 相似文献

“十五”期间紫阳县县委县政府把蚕桑作为主导产业来抓,制定出台了一系列鼓励发展的政策措施,加上近三年来国际茧丝绸市场好转,蚕茧价格上升,农民养蚕收益增加,栽桑养蚕积极性提高,全县蚕桑生产得到较快发展。2006年全县桑园面积已发展到0．52万hm^2,养蚕6．5万张,产鲜茧2058t,农民养蚕收入5500万元,已成为紫阳县农村经济的主要来源。 相似文献

淳安县地处浙江省西部山区,蚕桑生产从70年代末起逐步发展.党的十一届三中全会以来,各级政府部门十分重视蚕桑生产发展,从政策倾斜、经济扶持到科学规划、生产指导都做了大量工作,从上世纪80年代以来,淳安县蚕桑迅速发展,已成为本县农村主导产业之一,蚕桑业是农民家庭经济的主要来源. 相似文献

蚕桑产业是淳安农村经济的主导产业,是现阶段农民家庭经济收入的主要来源之一.全县现有2.4万户蚕农从事蚕桑生产,受益农业人口近8万,有桑园4520hm2,年产茧5000t,蚕桑总产值1.45亿元.但由于2000年以前推广的桑品种都是湖桑,且多数种在高山薄地上,树龄老化,单位面积产茧量较低.要提高蚕桑单位面积产茧量,要做强做大蚕桑产业,推广优质高产的桑树新品种是一项关键的措施.由于农桑系列品种可大幅度提高单位面积桑园产茧量和经济效益,淳安县在2001～2003年大力引进推广农桑12、14号新品种. 相似文献

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。 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

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
