我馆在2005年将中文图书库存本阅览室与中文图书外借库合并成中文书库,进行统一管理。本文结合工作实际,分析了书库合并前分开管理的弊端,阐述了二者合并的意义,提出了合并后的具体管理措施。     

田间小棚繁殖烟蚜茧蜂的繁蜂效果研究

研究了田间小棚繁殖烟蚜茧蜂的繁蜂效果,比较了在不同接蜂量和蚜量范围条件下的僵蚜数量及其羽化情况。接蜂量和接蜂时的蚜量是影响僵蚜数量的2个重要因素,以接蜂时的蚜量对繁蜂效果的影响更为明显。在接蜂量为蜂(♀)蚜比1∶100、蚜量范围2 000~3 000头/株的条件下,可获得较好的繁蜂效果,僵蚜的数量可达到8 000个/株以上。在繁蜂前期僵蚜的质量较高,僵蚜的羽化率可保持在90%以上,在繁蜂后期受重寄生蜂的影响,僵蚜的质量明显下降。应用田间小棚繁殖烟蚜茧蜂时,重寄生蜂是影响后期繁蜂质量的重要因素。     

The rates of maize growth and lignin biosynthesis change after root-applied chalcone

The effects of root-applied chalcone at 0.15 mmol L⁻¹ on the growth and lignin biosynthesis in maize were investigated. The contents of 4-coumarate: CoA ligase (4CL, EC 6.2.1.12) substrates in maize shoots were increased more rapidly in the samples with chalcone application than in the control and the increase occurred at ≤ 3 h after the application (HAA). The lignin content was reduced by chalcone at ≤ 6 HAA. The shoot growth was suppressed by chalcone at ≤ 9 HAA. Consequently, the results suggest that chalcone suppressed maize growth by inhibiting monolignol biosynthesis.     

母猪卧向行为学的观察

本文通过2个试验对母猪在分娩圈和分娩栏中的卧向行为进行了观察,试验一中, 选择10头大白(Yorkshire)经产母猪作为观察对象,试验二中分别选择10头大白(Yorkshire) 经产母猪和10头长白(Landrace)经产母猪作为观察对象。观察采用瞬时记录方法,每周观察 三次,隔日观察,每天上午、下午各观察一次,每次3 h,每次观察间隔5 min。观察中发现,母猪 卧向以向外为主。分娩栏(四周是栏杆)中的母猪以选择卧向外(向北)为主,其次是卧向内(向 南),卧向左和卧向右最少且差异不显著,上栏前和下栏后差异不显著。分娩圈(四周是墙壁)中 母猪以选择卧向外为主,卧向内最少,卧向左和卧向右差异不显著。长白母猪比大白母猪选择 卧向外的多,妊娠阶段比哺乳阶段选择卧向外的多。     

Selection and amplification of the liver stem cell subset from rat bone marrow cells with a medium containing cholestatic serum in vitro

AIM: To explore the feasibility of direct separat and selective enlargement of the bone marrow-derived liver stem cells (BDLSC) from bone marrow cells with a culture system containing cholestatic serum in vitro. METHODS: Bone marrow cells of rats were cultured with selective media containing 2%, 5%, 7% and 10% cholestatic rat serum, respectively. The BDLSC were then induced to proliferate with the addition of hepatocyte growth factor (HGF) on the firth day. BDLSC were characterized using immunocytochemistry and RT-PCR for lineage markers, glycogen staining and urea synthetic assay for functions 2 weeks later. RESULTS: Bone marrow cells were unble to form colony in the presence of 2% cholestatic serum and apopotosis appeared gradually in 7% or 10% cholestatic serum. The BDLSC survived in the medium containing 5% cholestatic serum while the other types of cells did not. The survival cells proliferated with a high speed during the second week and then formed hepatocyte-like colony-forming units (H-CFU). Cells in the H-CFU expressed the characteristic proteins of fetal hepatocytes. Furthermore, they had glycogen storage and urea synthesis functions, two of the critical features of hepatocytes. CONCLUSION: The selective micro-environment effectively selected BDLSC from the bone marrow cell, and will be a new way to provide an abundant source of donor hepatocytes for clinical cell therapy.     

达县分葱田甜菜夜蛾发生规律初步研究

采用系统调查方法研究了达县地区分葱田甜菜夜蛾的生活史、发生与环境的关系。甜菜夜蛾在达县分葱田1a发生6代,以三至五代为害最重,世代重叠。其数量消长与虫源、夏秋季气候、天敌、栽培管理等因素密切相关。通过调查分析提出本县初始虫源非本地虫源。     

马铃薯品种黔芋一号高产配套技术措施研究

采用二因素饱和D最优设计对黔芋一号施肥水平(氮、磷、钾固定比例2∶1∶4)、密度2个主要栽培措施进行了试验研究。结果表明,在中等土壤肥力条件下要获得1 900~2 250 kg/667m2的产量,可以采用施肥水平在13.96~16.98 kg/667m2与密度3 574~4 200株/667m2的组合方案;要获得大于2250 kg/667m2的产量,施肥水平应在14.98~16.57 kg/667m2,密度在4 200~4 884株/667m2为宜。

芽孢杆菌及其胞外多糖对空心菜和茼蒿Cd吸收及土壤团聚体的影响

本研究旨在探究产胞外多糖芽孢杆菌对蔬菜镉(Cd)积累及土壤结构的影响。采用以空心菜和茼蒿为供试材料的盆栽试验,研究了功能菌株Priestia megaterium YG35和Bacillus halodurans G20降低蔬菜吸收Cd的效果和可能作用机制。结果表明,与CK相比,菌株YG35、菌株G20及其胞外多糖处理显著增加空心菜和茼蒿可食用组织干质量(37.8%～115.1%),显著降低可食用组织Cd含量(21.9%～44.2%),并使茼蒿Cd含量(0.057～0.061 mg·kg^-1)达到安全可食用标准,显著降低根际土壤有效态Cd含量(3.7%～11.7%),显著(P<0.05)增加根际土壤多糖含量(35.9%～49.5%)和蔗糖酶活性(15.3%～28.4%),促进根际土壤团聚体向大粒径转化。研究表明,YG35和G20及其胞外多糖能降低蔬菜对Cd的吸收,促进蔬菜生长,改善土壤结构,具有在Cd污染土壤上实现蔬菜安全生产的应用潜力。
