摘　　要：本文研究优质甘薯—岩薯 5号生育特性表明 :高产系每公顷株数、薯数 ,单薯重协调发展的结果。地上 ,地下部处于合理的动态平衡中 ,促进块根形成早 ,膨大快 。The characteristics of growth and development for high yield of sweet potato cultivar “Yanshu No.5” were studied.The result showed that high yield result from harmonious development among plant number/ha,root tuber number and weight of single root tuber.The dynamic banlance between underground mass and above grond mass can promote forming root tuber early and expanding fast,which result in the characteristics of high yield and high economic coefficient.
