摘  要：
对叶菜型甘薯品种百薯1号的茎尖产量和薯块产量进行了研究。结果表明,随着采摘次数的增加,茎尖产量呈对数函数增加,其曲线方程为y赞=9921.500lnx+2671.300(R2=0.9918);随着采摘次数的增加,薯块产量呈直线函数降低,其回归方程为y赞=-2009.600x+35776.000(r2=0.9417);茎尖产量与薯块产量呈负相关关系,其直线回归方程为y赞=-0.636x+37246.000(r2=0.8264)。百薯1号表现茎尖产量和薯块产量双高产,在连续采摘7次茎尖条件下茎尖产量可达22305.0kg/hm2,同时薯块产量仍可达19311.0kg/hm2;在完全不采摘茎尖条件下,薯块产量则可达34908.0kg/hm2。

摘  要：
The top caudex yield and the tuber yield of sweet potato Baishu NO.1 as leaf-edible vegetable were studied in this paper.The results showed that the top caudex yield increased as logarithm with the equation y=9 921.500lnx+2 671.300 (R2=0.991 8)when the picking times was increased.the tuber yield reduced as linearity with the equation y =-2 009.600x+ 35 776.000 (r2=0.941 7) when the picking times was increased.There was positive pertinence between the top caudex yield and the tuber yield with the equation y =-0.636x+37 246.000(r2=0.826 4).The top caudex yield and the tuber yield were 22 305.0 kg/hm2 and 19 311.0 kg/hm2 respectively with picking seven times continuously,and the tuber yield was 34 908.0 kg/hm at the same time with no picking.
