| 1 | 大豆锈病初次侵染源调查及其作用分析显示文摘本调查基本确定了大豆锈病(Phakopsora pachyrhiza syd.)在南方的越冬范围为北纬23°55′以南;经综合分析锈病发生时期、锈病专性寄生性和气流传播特性、栽培葛、野生葛和大豆种植时期、生长季节、锈病发生实况与接种鉴定结果,基本确定南方的栽培葛(Pueraria lobata ohwi)和野葛(P.lobata(wild)ohwi)是大豆锈病病原菌的越冬寄主,其上发生的锈病是本地大豆锈病的主要初次侵染源之一;该区域发生的病原菌成为向北传播扩散的起始源;为今后大豆锈病的监测、预测预报与治理提供了可靠的依据。 | 莫贱友 郭堂勋 Xun-Li X.B.Yang | 2007 | 作物杂志2007，，5： | 2 |

| 3 | Designation of a binocular structure for complex sources of X-rays and neutron source显示文摘Purpose A structure,used as a complex source of X-rays and neutron source,is designed with the assistance of CST module tool.Methods Particles of H-and electron,attracted from a plasma source,are designed to be separated by an energy selector.Soon after the separation,the trajectory and beam quality of H-are controlled by a special designation of potential barrier and potential well.And both particles are then accelerated by three pairs of pierce similar pole to an energy of 150 keV to produce X-rays/neutron.Results With proper optimization of structure and potential combination,a binocular structure with beam center distance of 15 mm,beam diameter smaller than 3.5 mm has been devised,which gives a feasible suggestion to produce two rays with one structure in the same time. | X.B.Yang X.B.Qin P.H.Liu T.Li K.Zhuang | 2020 | Radiation Detection Technology and Methods2020，4，2： | 0 |
| 4 | 黑暗对大豆锈病菌侵染影响的研究显示文摘黑暗时长是影响大豆锈病侵染的重要因素之一,为了明确其影响的作用大小,我们应用大豆离体叶片培养技术,在24±1℃、相对湿度饱和的人工控制条件下试验,结果表明:黑暗培养8~16小时,有利于大豆锈病的侵染,延长或缩短黑暗培养时长,均不利于大豆锈病菌的侵染。 | 莫贱友 郭堂勋 Xun—Li X.B.Yang | 2008 | 农业科技通讯2008，，7： | 0 |
