城镇化发展中的小城镇特色建设问题研究     

张晓东  姚宗建 《安徽农业大学学报》2020,29(6):46-51

集中发展小城镇是我国城镇化发展的一个重要选择。当前我国小城镇特色建设面临着特色挖掘不突出、特色彰显能力弱、基础设施公共服务功能弱、创新精神不足以及缺乏活力等问题。小城镇特色建设必须坚持以适合人民生活为宗旨，以大中城市周边合理布局为基础并注重乡土重建，充分发挥原住民在小城镇特色挖掘上的主体作用，注重通过创新精神去激活发展动力，在保护和开发并重的前提下发挥政府搭建平台、城镇居民共同参与、开发资本“走进来”的三方协同作用来加强小城镇特色建设。  相似文献

秦岭南麓新分布小太平鸟迁徙期食性初步观察     

杨成群  袁朝晖 《陕西林业科技》2014,(6):32-33

2011-2013年冬季,作者采用分组全天跟踪的方法,调查小太平鸟迁徙期活动特征和食性。结果证明:小太平鸟冬季由北向南成群迁徙过程中,会在某个生境优良的区域停留取食9~15日、成群活动在树冠上部。小太平鸟在迁徙期停留区域取食植物果实种类有20种,有人工栽培树种果实,也有野生树种果实。今后应持续迁移路线、停歇地、种群动态监测。  相似文献   

Analysis on Function Orientation and Development Countermeasures of New Agricultural Business Entities     

《东北农业大学学报(英文版)》2016,(2):82-88

Along with the rapid advance of industrialization and urbanization process, fostering new agricultural business entities become inevitable for agricultural transformation and the construction of agricultural modernization in China. The status of the new agricultural business entities determines the level of modern agricultural development. In recent years, new agricultural business entities have grew rapidly. However, there are still many problems including the difficulties in financing loans, inadequate agricultural insurance system, bad implementation of agricultural subsidies, jagged agricultural talents and so on. In order to foster new agricultural business entities, countermeasures should be carried out to ensure financial support, perfect the agricultural insurance, strengthen the level of agricultural subsidies, strive to develop the degree of specialization agricultural operators and so on.  相似文献

Development and Application of Cotton InDel Markers Based on High Throughput Sequencing     

Lu Haiyan  Chen Lu  Wang Xiansheng  Zhao Han  Shen Qi 《棉花学报》2019,31(4):297-306

[Objective] Dimorphic InDel markers can be used for cotton variety identification and purity detection, to improve the accuracy and efficiency of cotton seed testing, and to play a role in molecular breeding of cotton. [Method] Based on the whole genome sequencing of 121 cotton varieties from different sources, the InDel markers with high polymorphism were developed according to polymorphism information content(PIC) and were applied in the genetic distance analysis and cluster analysis by using 66 cotton varieties in China. [Result] Totally 10 967 InDel were identified based on the next generation sequencing data of 121 cotton varieties. Among the 85 pairs of InDel primers synthesized, 64 were selected including 35 from At group and 29 from Dt group. The minimum average allelic frequency(MAF) of At and Dt chromosomes were 0.45 and 0.32, respectively, while the PIC were 0.49 and 0.40, respectively. The genetic distances of the 66 cotton varieties ranged from 0.04 to 0.65 centimorgan (cM), with an average of 0.39 cM. The two varieties with the largest genetic distance were Simian 3 and CCRI 36, and the two varieties with the smallest genetic distance were Xumian 18 and Xuza 3. [Conclusion] The 64 cotton dimorphic InDel markers can effectively reveal the relationships among varieties based on the genetic distance, and distinguish cotton varieties from different sources, which has certain theoretical significance and application value.  相似文献
