| 1 | Source-to-sink of Late carboniferous Ordos Basin: Constraints on crustal accretion margins converting to orogenic belts bounding the North China Block显示文摘The Upper Carboniferous Benxi Formation of the Ordos Basin is the lowest strata overlying Middle Ordovician above the major ca.150-Myr sedimentary gap that characterizes the entire North China Block(NCB).We apply an integrated analysis of stratigraphy,petrography,and U-Pb dates and Hf isotopes on detrital zircons to investigate its provenance and relationships to the progressive collisions that formed the Xing’an-Mongolia Orogenic Belt to the north and the Qinling Orogenic Belt to the south.The results show that,in addition to regional patterns of siliciclastic influx from these new uplifted sources,the Benxi Formation is composed of two sequences corresponding to long-term glacial-interglacial cycles during the Moscovian to lower Gzhelian stages which drove global changes of eustatic sea level and weathering.The spatio-temporal distribution of sediment isopachs and facies indicate there were two sediment-infilling pulses,during which the southern and the northern Ordos Basin developed tidal-reworked deltas.The age spectra from detrital zircons,trace element patterns and εNd(t)values reveal that the siliciclastics forming the southern delta was sourced in the Qinling Orogenic Belt,whereas the northern delta was derived from the Xing’an-Mongolia Orogenic Belt.The source-to-sink evolution of this Upper Paleozoic system records the progressive development of orogenic belts and uplifts forming on the southern and northern margins of the NCB prior to its collisions with the South China and the Siberian plates,respectively. | Anqing Chen Hao Zou James G.Ogg Shuai Yang Mingcai Hou Xiuwei Jiang Shenglin Xu Xiaoxing Zhang | 2020 | Geoscience Frontiers2020，11，6： | 3 |

| 7 | Effects of Sowing Time on Biological Yield of Forage Sorghum[Sorghum bicolor(L.) Moench] in Autumn Idle Land显示文摘[Objective] This study was performed to explore the correlation between sowing time and biological yield of forage sorghum in autumn. [Method] In field trials,forage sorghum was sown on six different dates( July 23,July 29,August 6,August 14,August 22 and August 30). Then,seedling emergence stage,jointing stage,booting stage,heading stage,filling stage,fresh weight and dry weight in each plot were observed or measured. Finally,linear regression analysis on these data was carried out to deduce the correlation between sowing date and biological yield of forage sorghum. [Result]Sowing time showed a significant influence on biological yield of forage sorghum in idle land,and the biological yield of forage sorghum linearly decreased with the postponement of sowing time. The relationship between sowing time and biological yield of forage sorghum can be represented by the regression equations y_(fresh)= 196. 646-4. 625 x and y_(dry)= 58. 253-1. 423 x,wherein,x is sowing date,y_(fresh)and y_(dry)are the fresh weight and dry weight of forage sorghum. On average,the fresh weight of forage sorghum was reduced by 4. 625 kg/20 m^2,and dry weight by 1. 423 kg/20 m^2,when the sowing date was delayed by one day from July 23 to August 30. [Conclusion]The regression models built in this study will provide a theoretical basis for improving the yield of forage sorghum in autumn idle land. | Hanzhang ZHOU Huan LIU Xinjian ZHOU Haiyan JIA Zhimin WEI Shunguo LI Shenglin HOU | 2017 | Agricultural Biotechnology2017，6，5： | 0 |

| 9 | The Research on Identification of Resistance to Sorghum Aphid [Melanaphis Sacchari(Zehntner)] Employing Indoor Artificial Infestation Technique显示文摘[Objective] The paper was to establish a quick and effective indoor identification method of sorghum resistance to aphid uninfluenced by seasons.[Method] Based on the indoor reproduction technique of aphids,the sorghum varieties with different resistant performances against aphids in fields were conducted inoculation test in the laboratory according to different seedling culture media,different survey periods of aphid quantity,different leaf ages for inoculation,different inoculation quantity of aphids and different aphid sizes. Three hundred sorghum materials were identified in both laboratory and field. [Result] The number of aphids per seedling on the fifth day after inoculation gave the best score of plant resistance to sorghum aphid by using the loam as the seedling culture media,and inoculating three different sizes of aphids in seedlings at two-leaf stage. Thus,the indoor identification technique of resistance to sorghum aphids was as follows:(1) sorghum seeds were sown in loam at room temperature of 22-26 ℃ and air humidity of 55%-75%;(2) three aphids with different sizes were inoculated in seedlings at two-leaf stage;(3) the number of aphids per seeding were surveyed on the fifth day after inoculation;(4) plant resistance to sorghum aphid was evaluated according to number of aphids per seedling on the fifth day after inoculation. The resistant grade of sorghum variety was evaluated according to distribution of aphid quantity per seedling in a 100-seedlings population. The resistance materials identified by indoor method at seedling stage had consistent performance with field identification. [Conclusion] The method could be used for resistance identification of sorghum varieties and hybrids,and accurate identification and selection of individual resistance of hybrid offspring,which could improve selection efficiency of individual resistant plant against aphids in hybrid offspring and identification accuracy of individual resistant plant among molecular marker population. | Lv Peng Qi Yameng Liu Guoqing Hou Shenglin Li Suying Ji Guisu Ma Xue Du Ruiheng | 2013 | Plant Diseases and Pests2013，4，3： | 0 |
| 10 | Environmental Factors Influencing Seed Germination Characteristics of Vicious Weed Green Foxtail显示文摘[Objective] The paper was to optimize the optimal conditions for seed germination and seedling emergence of green foxtail [Setaria viridis(L.)Beauv.],so as to solve the problem of serious damage caused by green foxtail. [Method] Using the orthogonal test and the LSD method of software SPSS 18.0,with the number of emerged seedlings of green foxtail as the evaluation index,the influencing factors such as pretreatment of green foxtail,earth covering depth,soil temperature and soil moisture content were compared in the test. [Result] These four experimental factors had great impact on seed germination characteristics of green foxtail. The optimal scheme for seedling emergence of green foxtail was as follows: pretreatment of green foxtail for 3 d,earth covering depth 0.5 cm,soil temperature 32 ℃,soil moisture content 15%. The optimum condition was consistent with the actual situation of serious damage of green foxtail (suffering moderate and heavy rainfall after sowing and before seedling of millet). Avoiding sowing millet before moderate and heavy rainfall could effectively control serious damage of green foxtail. [Conclusion] The study provided theoretical support for effective control against the vicious weed green foxtail. | Lv Peng Duan Xishun Bo Kuiyong Zhao Yu Hou Shenglin Wang Xinyu Jia Haiyan Ma Xue Xiang Ji-nying Liu Huan Zhou Hanzhang | 2013 | Plant Diseases and Pests2013，4，3： | 0 |
