数字乡村建设是乡村振兴的重要方向,也是实现共同富裕目标的主要途径。文章基于2011-2020年中国31个省份的面板数据,分别构建共同富裕与数字乡村建设评价指标体系,考察数字乡村建设对共同富裕的影响效应和作用机理。结果表明:(1)中国数字乡村建设水平与共同富裕水平均在上升,且均呈现“东高、西低”的空间分布格局,但中西部地区的“追赶”效应明显;(2)数字乡村建设对共同富裕具有显著的促进作用,并且其促进共享富裕的“分好蛋糕”效应强于促进总体富裕的“做大蛋糕”效应;(3)机制分析表明,数字乡村建设主要通过农民收入增长、农村创业活力和农村产业融合三种渠道促进共同富裕;(4)在空间异质性视角下,数字乡村建设对共同富裕的促进效应从东部到西部依次递增。

The Crop Journal 2021年第4期9卷 816-822页

Thinopyrum intermedium has been used as a resource for improving resistance to biotic and abiotic stresses and yield potential in common wheat. Wheat line SN304 was derived from a cross between common wheat cultivar Yannong 15 and Th. intermedium. Genomic in situ hybridization(GISH) produced no hybridization signal in SN304 using Th. intermedium genomic DNA as a probe, but fluorescence in situ hybridization(FISH) using oligonucleotides AFA-3, AFA-4, pAs1-1, pAs1-3, pAs1-4, pAs1-6, pSc119.2-1,and(GAA)10 as probes detected hybridization signals on chromosomes 2 A, 7 A, 2 B, 3 B, 6 B, and 7 B in SN304 that differed from Yannong 15. Results of specific markers also indicated that there were Th. intermedium chromatin introgressions on different chromosomes in SN304. In a hydroponic culture experiment, SN304 not only produced more biomass and higher stem and leaf dry weight but also accumulated more phosphorus than Yannong 15 under phosphorus-deficiency stress. Moreover, SN304 produced a lower pH and released more organic acids, especially oxalic acid, than Yannong 15, which suggests that SN304 exudates enabled more absorbance of P than Yannong 15 under comparable *** results indicate that SN304 is a wheat-Th. intermedium introgression line with tolerance to phosphorus-deficiency stress.
