我国木皮产业发展渐趋成熟     

享尔 《国际木业》2008,(4):39-41

近年来,以往不被木材加工行业和广大消费者群体接受和认可的数以百计的木制品之中的小产品——木皮,越来越受到生产和加工木材制品的企业欢迎与青睐,而且逐渐在市场上经受住了考验与洗礼。从我国东南沿海及许多大中型城市的木材制品的销售情况来看,凡是使用了木皮作为贴面的产品,都要受到市场的热捧,尤其是天然木皮产品更是待遇有加。正因为拥有了广大消费者也就是消费市场的“准入证”和“通行证”,  相似文献   

Pathogenicity of Vibrio Coli for Swine I. Experimental Infection of gnotobiotic Pigs with Vibrio Coli   总被引：1，自引：1，他引：0       下载免费PDF全文

C. E. Andress  D. A. Barnum    R. G. Thomson 《Canadian journal of veterinary research》1968,32(4):522-528

Fifteen gnotobiotic pigs varying in age from three to eight weeks were exposed to 23 strains of V. coli isolated from swine with clinical and/or pathological signs of swine dysentery and also from clinically healthy pigs. Clinical or pathological signs of swine dysentery were not produced, although the organism was readly established in the sedimentary tract. Culture of feces, alimentary tract and environment revealed V. coli in large numbers, but no bacterial growth was obtained from other organs. The histopathology and serology are discussed.  相似文献

荒漠区开垦干扰下子午沙鼠种群数量动态与繁殖特征     

鄂晋  张福顺  余奕东  付和平 《内蒙古农业大学学报(自然科学版)》2009,30(2):140-144

子午沙鼠(Meriones meridianus)是我国半荒漠、荒漠地区的常见鼠种之一,是内蒙古阿拉善荒漠的优势鼠种,也是荒漠草原的主要害鼠.2002年-2006年每年4月、7月、10月上旬,采用铗日法,对内蒙古阿拉善荒漠开垦区子午沙鼠种群数量及繁殖情况进行了专门调查,结果表明,子午沙鼠种群的数量变动可以引起种群内繁殖特征的变化,而繁殖特征的变化也直接影响种群数量.种群数量调节表现为典型的密度制约.种群数量升高时雌雄性比和胎仔数相对下降.反之则雌雄性比和胎仔数相对升高.繁殖特征的变化在一定程度上可以起到调节种群数量的作用.  相似文献

为探寻新疆南疆地区籽棉9000 kg·hm-2超高产机理以及相关的指标,对南疆地区生态条件下超高产田、高产田、中高产田进行了调查研究与数据采集。研究发现:要获得超高产,首先要有良好的基础地力,有机质含量超10 g·kg-1,种植密度18×104~21×104株·hm-2为宜;其次,塑造良好株型,株高65~75 cm,茎粗接近10 mm,果枝9~10台,棉铃空间分布均匀,纵向上、中、下果枝棉铃比例3.2∶4.7∶2.1,横向第一、二果节比例7∶3,初花至盛铃LAI、SPAD、Pn一直维持较高水平,盛铃前后达到最大,后期下降缓慢;最后,氮磷钾分配上,前期差异不大,进入花铃期生殖生长明显增强,蕾花铃氮磷钾比例明显增大,一直维持到见絮,超高产处理的蕾花铃干物质量比例明显高于其它处理8%以上,见絮时蕾花铃干物质量达到了6 402 kg·hm-2。以指标数据作参考,塑造良好株型,协调棉铃空间分布,维持较高较长的光合速率,减缓LAI、SPAD下降速度,促进生殖生长,合理养分分配,便能实现产量目标。  相似文献

Efficacy of doramectin 0.5% w/v Pour-On for control of the horn fly, Haematobia irritans     

Andress ER  DeRouen SM  Foil LD 《Veterinary parasitology》2000,90(4):261-331

In 1998, three groups of cattle at three locations in Lousiana were treated with Dectomax^® (0.5% doramectin) Pour-On and horn fly populations were monitored. Acceptable levels (less than 50 flies per side) of horn fly control were observed from 4 to 8 weeks. Differences in the length of control among the three sites were most likely affected by immigration of adult flies from untreated groups. In 1999, acceptable horn fly control was obtained for 13 weeks by the use of two treatments of doramectin Pour-On.  相似文献

Fortification of pork loins with docosahexaenoic acid(DHA) and its effect on flavour     

William  J  Meadus Tyler  D  Turner Michael  ER Dugan  Jennifer  L  Aalhus Pascale  Duff David  Rolland Bethany  Uttaro Lorna  L  Gibson 《畜牧与生物技术杂志(英文版)》2014,(1):106-113

Pork is traditionally low in docosahexanoic acid(DHA, C22:6n-3) and deficient in omega-3 fats for a balanced human diet. DHA as triglycerides was commercially prepared from the microalgae Schizochytrium and injected into fresh pork loins. Treatments of a mixed brine control(CON), 3.1% sunflower oil in mixed brine(SF) and a 3.1% DHA oil in mixed brine(DHA) were injected into pork loins at 10 mL/100 g and grilled at 205°C. After cooking, the CON and SF pork loins contained 0.03 to 0.05 mg DHA/g of pork and the DHA injected loins contained approximately1.46 mg DHA/g. This also changed the fatty acid profile of omega-6: omega-3 from, 5 to 1 in the CON pork, to a ratio of 1.7 to 1 in DHA pork. The appearance, odor, oxidation rates and sensory taste, as judged by a trained panel,determined the DHA injected meat to be, ‘slightly desirable' and gave lower ‘off flavour' scores, relative to the CON and SF injected pork. Pork can be fortified with DHA oil to 146 mg/100 g serving, which would meet half the recommended daily omega 3 fatty acid requirements for adult humans and would be desirable in taste.  相似文献
