宁夏固原山区蜂产业助推脱贫攻坚的思考     

李勇  罗应国  张瑞  苏萍  李萍 《中国蜂业》2021,(2):48-48,50

环六盘山区作为深度贫困地区脱贫攻坚战的主战场之一,在党中央、国务院的关怀和大力支持下,各级党委政府高度重视,积极发挥产业优势,有力地推动了脱贫攻坚战的顺利实施。固原市是环六盘山区的核心地区,也是全国重点贫困地区,“干旱少雨、山大沟深、生态脆弱、产业单一”是当地经济发展的写照,曾被世界教科文组织认定为“最不适宜人类居住的地区之一”,因此,固原市在农业产业领域内,充分发挥肉牛、马铃薯、蔬菜、小杂粮和蜜蜂五大特色农业产业优势,通过“引项目、注资金、强技术、连帮带”等措施全面推进产业扶贫政策,起到了非常好的作用。  相似文献

Submitting canine blood for prothrombin time and partial thromboplastin time determinations   总被引：2，自引：1，他引：1

Practitioners commonly submit samples from dogs for partial thromboplastin time and prothrombin time determinations. Controversy exists as to the necessity for rapid separation of plasma and cells, and submission of the plasma on ice (or frozen). The purpose of this study was to address three questions. First, is it better to submit plasma or is whole blood satisfactory? Second, is it necessary to refrigerate the sample or is maintenance at room temperature (20° C) adequate? Third, does the sample have to arrive at the laboratory within a few hours of collection or can reliable partial thromboplastin time/prothrombin time determinations be made on samples up to 48 hours old?It has been shown by this study that reliable partial thromboplastin time and prothrombin time determinations can be carried out on canine plasma for up to 48 hours after collection regardless of whether or not the plasma is separated immediately; however the samples must be kept at 4°C. If the samples are maintained at room temperature, reliable prothrombin time determinations can be obtained for up to six hours after collection regardless of whether or not the plasma is separated immediately. Reliable partial thromboplastin time determinations can be made on plasma stored at 20°C for up to 24 hours after collection and possibly longer (up to 48 hours) if the plasma has been separated immediately.  相似文献

An evaluation of an oral formulation of moxidectin against selected anthelmintic-resistant and -susceptible strains of nematodes in lambs     

Bisset SA  Vlassoff A  McMurtry LW  Elliott DC  Cobb RM  Kieran PJ  Wood IB 《New Zealand veterinary journal》1992,40(3):97-100

The efficacy of an oral formulation of the newly developed parasiticide, moxidectin, was tested against benzimidazole-resistant Haemonchus contortus, Trichostrongylus colubriformis, and Nematodirus spathiger, levamisole-resistant Ostertagia circumcincta, and susceptible Cooperia curticei infections in weaned lambs. Thirty-two lambs were experimentally infected with mixed doses of the above strains of nematodes. They were allocated into four treatment groups by stratified randomisation using liveweights and faecal egg counts 28 days later. One group received moxidectin at 0.2 mg/kg liveweight, one group oxfendazole at 4.5 mg/kg liveweight, one group levamisole at 7.5 mg/kg liveweight and the last group remained untreated as the control. Worm burdens in the lambs at slaughter 10 days after oral treatment confirmed the resistance status of the nematode strains used, and showed that moxidectin had a greater than 99.9% efficacy (p<0.01) against all of them. No adverse effects due to treatment with moxidectin were observed in any of the animals.  相似文献   

长江1号苇状羊茅选育报告   总被引：1，自引：0，他引：1  

何丕阳张新跃  何光武张瑞珍 陈艳宇 《四川草原》2005,(2):22-26

以四川省20世纪80年代所进行牧草引种试验的苇状羊茅材料存留株为原始群体,采用单株混合选择法,经10多年的选育,育成新品种长江1号苇状羊茅。该牧草青绿期长、耐热、抗旱、耐瘠薄,耐伏旱高温;种子成熟期集中,种子产量高于对照品种Fawn苇状羊茅40%左右,干物质产量比对照提高10%以上,适应我国长江中下游低山、丘陵等地区种植,是建立人工草地、改良天然草场和生态建设的优良牧草。  相似文献

牧草生育期是影响牧草产量的重要因素,为了培育出生育期短、高产量的优质牧草新品种,以母本‘永492’和父本‘歇里·努瓦尔’进行种间杂交选育出燕麦饲草新品种‘蒙饲燕2号’。‘蒙饲燕2号’具有较强的抗旱耐盐以及抗倒伏能力。生产试验结果表明,2015—2016年‘蒙饲燕2号’燕麦草的平均鲜草产量、干草产量及种子产量分别为32 406.06kg·hm~(-2),10 935.85kg·hm~(-2)和2 364.91kg·hm~(-2),较对照品种分别平均提高了19.49%,19.22%和5.84%。生育期90天,株高135cm,穗长20.4cm;穗粒数65.5个,穗粒重1.25g;千粒重31.0g。在内蒙古及其毗邻省区均可种植。  相似文献
