Xueshan Township,Luquan Yi and Miao Autonomous County of Yunnan Province,located in the alpine valley of Jinsha River,is a major township with wide and deep poverty,and the incidence of poverty is up to 45. 00%. In recent years,Xueshan Township has insisted on the battle against poverty,made effort to develop the Codonopsis pilosula industry,and successfully developed a road to poverty alleviation through C. pilosula industry,and formed a unique industrial poverty alleviation model by the end of 2018,the incidence of poverty dropped to 0. 74%. Based on field survey and interview,this paper analyzes and summarizes the specific practices,main results,practical experience and promotion and application measures of the poverty alleviation model of C. pilosula planting industry in Xueshan Township,in the hope of providing certain reference for the targeted poverty alleviation in similar areas in Yunnan Province and other provinces of China.展开更多

The trial excavation recovered a semi-subterranean house foundation (F1) and a stilt house foundation (F2). The potteries and bronze arrowheads unearthed from F1 were similar to the artifacts of Shizhaishan Culture and therefore this house foundation would have belonged to Shizhaishan Culture, and was used as refuse pit after it was abandoned in the Six Dynasties Period. Only a small part of F2 was recovered in this excavation and its date is still waiting for further fieldwork.展开更多
试验选用26周龄的雪山鸡所产的种蛋分别按不同重量分组入孵后,分析种蛋重量对孵化效果的影响。结果表明:种蛋重量在41.1～57.0 g 之间的孵化效果较好,蛋重在37.1～41.0 g 之间的受精率、活胚率、入孵蛋孵化率、活胚蛋孵化率和健雏率均...试验选用26周龄的雪山鸡所产的种蛋分别按不同重量分组入孵后,分析种蛋重量对孵化效果的影响。结果表明:种蛋重量在41.1～57.0 g 之间的孵化效果较好,蛋重在37.1～41.0 g 之间的受精率、活胚率、入孵蛋孵化率、活胚蛋孵化率和健雏率均显著低于其它各组(P<0.01)。至18日胚龄时,种蛋重量在41.1～57.0g 之间的相对失重较其他各试验组低。相对失重越低,入孵蛋孵化率越高。因此在生产中,应该采用重量适合的种蛋进行孵化。展开更多
