| In order to investigate the affect of yam anthracnose occurrence by cultivation and management measuresin southern Guangxi,it was be studied that the seed and covering treatment,plant density and nitrogen fertilizer affectedyam anthracnose by field test method.The results show that:in the southern area of guangxi,the good seed and black film（grass or moss） covering measures,reasonable density（667m2 implant 1100-1150 strain）,the appropriate amount of nitrogen topdressing（ seedling nitrogen fertilizer 10 or 15 kg） can reduce the harm to anthracnose in yam production and raise the yield. |
