我国是世界上可再生能源原料产出量最大的国家,每年产生农作物秸秆7.0亿t,黑龙江是我国粮食安全的重要战略基地,对保障我国粮食安全具有极其重要的作用。针对黑龙江秸秆还田后的化感效应问题,国家开展了相关课题的研究。在中国北方地区,小麦-玉米两熟种植制度下,大量玉米秸秆连年己显著影响了小麦生长发育及土壤生态系统,在黑龙江省农田生态系统中,玉米秸秆还田后长期连作是否存在自毒效应尚不清楚,且未有相关研究报道
干旱胁迫是影响作物生长、发育的重要限制因子,研究水稻的抗旱性,对节水农业具有重要理论和现实意义。本研究以旱稻品种IRAT109干旱处理幼苗和抗旱大棚内的成株期植株为材料,制作Affymetrix表达谱芯片。选取了芯片结果中上升表达强度第二的基因(OSI2),对其进行了克隆和功能的初步研究。本实验也做了Picloram对水稻愈伤组织生长的影响研究。其结果如下:1.通过RT-PCR和RACE技术相结合
AIM: To understand pharmacophore properties of styrylquinoline derivatives and to design inhibitors of HIV-1integrase. METHODS: Comparative molecular field anal
花生(Arachis hypogaea L.)是重要的油料作物和经济作物,但由于花生遗传基础狭窄、抗逆性差,易感多种病虫害,尤其是褐斑病、黑斑病、网斑病等真菌性病害,严重影响其产量和质量。
AIM: To investigate whether increased plasma L-homocysteine (Hcy) level could promote monocyte chemoattractant protein-1 (MCP-1) and interleukin-8 (IL-8) in cul
AIM: To investigate the immunoenhancing activity of ginsenoside-F3 in murine spleen cells and explore its mechanism.METHODS: The enhancing effect of ginsenoside
采用氮钾二因素饱和D—最优回归设计,研究K_(326)在大田追肥期,不同氮钾配比对烤后上部烟叶外观质量、主要化学成分和香吃味品质的影响,研究表明:烟叶均价与上等烟比例的变化趋势基本相似,在烤烟的第一次追肥过程中,均随着氮、钾施用量的增多而表现出先升后降的趋势;对总氮、烟碱、蛋白质等含氮化合物而言,氮肥效应均较钾肥效应大,都随着氮肥用量的增多表现出先升后降的趋势。对还原糖和钾离子来说则相反,均随着氮
AIM: To develop a specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the pharmacokinetic study of magnesium lithospermate B (MLB), an
