中国是世界上最大的甘薯生产国。广东是主要的种植省份之一,年种植面积800—1000万亩。广东地处热带和亚热带,气温高、雨量多。甘薯的生态条件与东南亚及非洲沿海国家较为接近。因此,广东培育的甘薯品种通常适宜于热带和亚热带地区种植。如我们早年选育的广薯16号、广薯70—9等甘薯品种在菲律宾、毛里求斯等国家种植,都获得显著增产。由于甘薯瘟病、疮痂病均是广东和这些热带地区的主要病害,严重阻碍着甘薯产量的提高,
China is the largest sweet potato producer in the world. Guangdong is one of the main planting provinces with an annual planting area of 800-1000 mu. Guangdong is located in the tropics and subtropics, high temperature, rainfall and more. The ecological conditions of sweet potato and Southeast Asia and African coastal countries are closer. Therefore, sweet potato varieties cultivated in Guangdong are usually suitable for planting in tropical and subtropical regions. For example, sweet potato varieties such as Guangshu 16 and Guangshu 70-9, which were bred early in the year, have been significantly increased in areas such as the Philippines and Mauritius. Due to sweet potato blast, scab disease are the main diseases in Guangdong and these tropical regions, seriously hinder the increase of sweet potato yield,
