国际马铃薯中心和山东省农业科学院于1999年10月10日至17日在该院生物技术研究中心联合举办了全国马铃薯、甘薯病毒检测技术培训班。来自广东、青海、贵州、河南、北京、黑龙江、内蒙等20个省、市、自治区33个单位的50多名学员参加了培训并获得了结业证书。我国是世界上薯类作物生产最大的国家。目前全国甘薯种植面积约670×10~4hm~2,马铃薯340×10~4hm~2,分别占世界种植总面积的85%和15%左右。但生产水平偏低,如马铃薯,全国平均水平仅12t/hm~2,远远低于发达国家20～40t/hm~2的生产水平。近年来由于病毒侵染造成的减产每年都在20%以上,损失相当严重。对病毒性危害仅通过增加投
The International Potato Center and Shandong Academy of Agricultural Sciences jointly organized a national potato and sweet potato virus detection technology training course at the Biotechnology Research Center of the hospital from October 10 to 17, 1999. More than 50 trainees from 33 units in 20 provinces, cities and autonomous regions in Guangdong, Qinghai, Guizhou, Henan, Beijing, Heilongjiang and Inner Mongolia participated in the training and obtained the certificate of graduation. Our country is the country that produces the largest potato crops in the world. At present, sweet potato planting area is about 670 × 10 ~ 4hm ~ 2 and that of potato is 340 × 10 ~ 4hm ~ 2, accounting for 85% and 15% of the total area planted respectively in the world. But the production level is low, such as potato, the national average of only 12t / hm ~ 2, far below the developed countries 20 ~ 40t / hm ~ 2 production level. In recent years, due to the virus infection caused by the reduction every year in more than 20%, the loss is quite serious. Viral hazards only by increasing investment
