| 1 | Prevalence Reasons and Monitoring Countermeasures of Scab in Eastern Wheat Area of Jiangsu Province显示文摘With the increasing prevalence frequency and aggravating harm degree in the 21 stcentury,wheat scab had become a recurrent disease in eastern wheat area of Jiangsu Province. This paper reviewed general occurrence situation of wheat scab in eastern Jiangsu,and summarized its occurrence characteristics in last decade. The disease prevalence was elaborated from the aspects of fungal source quantity,climatic conditions,cultivation modes,variety resistance and pesticide resistance. The author put forward a series of measures and countermeasures,including strengthening resistance monitoring and early warning,promoting and cultivating disease-resistant varieties,compressing planting area of direct seeding rice,carrying out chemical control scientifically,and realizing unified prevention and control,in order to provide a scientific basis for the control of wheat scab. | Chen Yongming Lin Fugen Zhao Yang Huang Tingting Ding Lei Mei Aizhong Cheng Xiaosong | 2016 | Plant Diseases and Pests2016，7，2： | 0 |
| 2 | Disaster Prevention and Mitigation Technologies of Rice Virus Diseases Spread by Small Brown Planthopper (SBPH)显示文摘Rice stripe virus disease( RSVD) and rice black-streaked dwarf virus disease( RBSDVD) are two epidemic diseases in Yancheng City,Jiangsu Province in the last decade. The authors investigated the disaster regularity,prevention and control technology of RSVD and RBSDVD systematically. The occurrence and virus transmission of SBPH and disaster regularity of virus diseases were studied; the resistance of some rice varieties was cleared; the effects of physical and agricultural measures such as insect net blocking,appropriate late sowing and plowing on controlling occurrence and virus transmission of SBPH were figured out;a batch of chemical agents were screened,providing efficient and harmless pesticides for effective control against SBPH and prevention against virus diseases. A set of disaster control and mitigation technologies was proposed in this paper,which was practical,sustainable,and easy to operate for the local planting patterns. | Lv Weidong Chen Yongming Lin Fugen Qiu Guangcan Qiu Xueping Li Ying Zhang Kailang Huang Tingting | 2017 | Plant Diseases and Pests2017，8，1： | 0 |
| 3 | Broadening and enhancing emission of Cr^(3+) simultaneously by co-doping Yb^(3+) in Ga1.4ln0.6SnO5显示文摘Cr^(3+)doped broadband near-infrared(NIR) emitting phosphors are currently the focus of research.Researchers have developed a variety of strategies to achieve broad and strong NIR emission,However,it is a conundrum to simultaneously broaden and enhance the emission of Cr^(3+)with a single strategy,In this work,we solved this problem by co-doping Yb^(3+).Under 452 nm excitation,Ga_(1.4)In_(0.6)SnO_(5)(GISO):0.01Cr^(3+)shows ultrabroadband NIR emission covering 650-1300 nm with a peak of 884 nm,The full width half maximum(FWHM) of the emission is 215 nm and the internal quantum yield(IQY) is 25%.This indicates that the double sites occupation strategy is favorable to achieve ultra-broadband NIR emission.The co-doping of Yb^(3+)can effectively broaden and enhance the emission of Cr^(3+).The FWHM for GISO:0.01Cr^(3+),0.002Yb^(3+)extends to 245 nm,and the IQY increases to 28%.Further increasing the concentration of Yb^(3+)to 0.005,the IQY is lifted to 32%.Finally,a phosphor-co nverted light emitting diode(pc-LED) was prepared by integrating the GISO:0.01Cr^(3+),0.002Yb^(3+)with a blue light chip.Under the current drive of 40 mA,the maximum output power of pc-LED is 4.54 mW,and the photoelectric conversion efficiency is 4.12%.These results indicate that Yb^(3+)ions can simultaneously broaden the emission band and improve the emission efficiency.This work provides an effective strategy for the design of efficient broadband NIR phosphors in the future. | Shuang Zhao Zhongfei Mu Lulu Lou Shuwen Yuan Min Liao Qiuming Lin Daoyun Zhu Fugen Wu | 2023 | Journal of Rare Earths2023，41，12： | 0 |
| 4 | Carbon-bridged Tri(cyclopentadiene):Synthesis and Coordination with Ytterbium显示文摘Reaction of a mixture of 1,1-bis(cyclopentadienyl)cyclohexane and pentamethylenefulvene with metallic sodium in THF led to a mixture of cyclohexylidene-bridged bis(cyclopentadienyl)sodium and two-cyclohexylidenebridged tri(cyclopentadienyl)sodium.Reaction of the salt solutions with anhydrous YbCl_(3)in THF afforded a ytterbium complex mixed-ligated by bridged bis(cyclopentadienide)and bridged tri(cyclopentadienide). | Lin Sha Li Li Fugen Yuan | 2014 | Chinese Journal of Chemistry2014，32，12： | 0 |
