苏渝303 栽后发根还苗快,结薯早,前期茎叶生长势旺,叶面积指数、总光合势和净同化率明显高于对照品种徐薯18 。干物质积累在生长的前90d 显著快于徐薯18 ,后期则略有减弱。苏渝303 的生物产量和经济产量分别比对照徐薯18 高19-3 % 和28-7 % ,经济系数比徐薯18 高7-6 % 。
Suyu 303 planted hair after the seedling fast, tuber early, early vigorous growth of stems and leaves, leaf area index, total photosynthetic potential and net assimilation rate was significantly higher than the control variety Xushu 18. Dry matter accumulation in the first 90 days of growth was significantly faster than that of Xushu 18, but slightly weakened in the late stage. The yield and economic yield of Suyu 303 were 19-3% and 28-7% higher than that of the control Xu-shu 18, respectively, and the economic coefficient was 7-6% higher than that of the Xu-shu 18.
