摘　　要：苏薯 9号栽后发根量多 ,返苗快 ,结薯早 ,前期生长势旺 ,净同化率高。干物质积累在前 70d明显快于对照品种徐薯 1 8,后期优势减弱。在氮、磷、钾配合施用时 ,苏薯 9号的鲜薯、薯干和茎叶产量随施氮量的增加而提高。Sushu 9 has more roots,grows faster and roots enlarge earlier than Xushu 18(CK) after planting.Sushu 9 has higher rate of net assimilation.During the 70 days after planting,the dry matter accumulation of Sushu 9 is faster than that of Xushu 18,but it is not obvious at the late stage of growth.When N,P and K are used in combination,the yield of root and vine will be enhanced by N increasing.[HJ5:1]
