猪牛羊鸡新疫病中西结合防制

在近几年经济发展过程中,我国的养殖业也在快速发展,养殖业呈现整体的规模化和集约化的发展趋势,但是在具体的养殖过程中,对于养殖疫病的问题也是越来越突出,这种疫病问题,在一定程度上制约了整个养殖业的发展,同时也会给养殖农民,带来一定的经济损失,尤其近几年中,对于猪牛羊鸡疫病的不同种类的爆发,都给我们的经济发展和日常生活带来了一定的损失,因此我们要及时的针对这些疫病发生的气候环境和生长条件等,进行原因分析,及时进行药物制止,可以通过中西医防治的措施,来阻止疫情的蔓延,促进整体养殖业的发展。

县域环境污染综合整治中低碳高值农业技术研究——以韶山灌区在建生态循环农业园种养业发展为例

探索县域城乡环境污染综合整治方略,以微观、宏观与动态视角三结合的研究方法,揭示了韶山灌区湘乡湘潭等县市及其周边地区农村水质、土壤与大气污染的严重性;提出了城乡"四维污染"的控制对策——低碳高值农业及其技术创新;且以韶山灌区在建生态循环农业园种养业产前、产中与产后深加工三部分低碳高值化技术创新产业化示范为驱动力,力求推进稻、草、树、药和猪、牛、鸡、鸭、鱼的低碳生态种养业,缓解以往种养业结构失衡、"谷贱伤农"与社会-经济-生态效益"短腿"问题的解决。结果表明,低碳高值农业体系是一个基于生态学的促进物质多层分级利用、节能降耗、清洁生产的多联产技术系统。

A Zooarchaeological Study on the Origins of Animal Domestication in Ancient China

A series of criteria such as morphological metrics, pathology, age structure, sex ratios, relative proportions, archaeological phenomena, diet analysis, and DNA studies are established for identifying the origins of domestic animals in ancient China in a scientific way. Using these criteria, it is established that the earliest domestic dog has been found in southern Hebei Province(ca. 10,000 BP), and the earliest domestic pig in southern Henan Province(ca. 9000 BP). Domestic sheep have been found in the Gansu–Qinghai region dating from 5600–5000 BP, and domestic cattle in eastern Gansu Province(ca. 5000 BP). Domestic horses from the period 4000–3600 BP have been discovered in eastern Gansu, and domestic chickens have been identified from sites in eastern Henan Province dating to ca. 3300 BP. Although the locations and time of the origins of animal domestication vary, they are mostly located in northern China.
