　　以单作马铃薯为对照，设置2∶2和3∶2两种薯玉行比，研究马铃薯、玉米套作对马铃薯干物质积累、转运、分配的动态变化。结果表明：套作显著降低了马铃薯干物质积累，却促进了干物质向块茎转运和分配，并提高了套作的根冠比。整个生育期马铃薯干物质积累呈慢-快-慢的特点。2∶2行比叶、茎干物质积累到达峰值和向块茎转运早于3∶2行比。套作2∶2行比干物质积累量低于套作3∶2行比，向块茎转运量高于套作3∶2行比。整个生育期干物质向块茎分配呈上升趋势，向叶、茎的分配呈下降趋势，升幅和降幅套作低于单作，2∶2行比低于3∶2行比。干物质向茎分配下降幅度小于向叶分配。干物质向各器官的分配为叶＜茎＜块茎。

The potato/maize intercropping field experiment was carried out in order to determine the dynamic changes of dry matter accumulation, translocation and distribution of potato , the sole crop potato as contro1.Two potato to maize ra-tios were employed,2:2 meaning two rows of potato plus two rows of maize while 3:2 meaning three rows of potato togeth-er with two rows of maize.The results showed intercropping led to significant decline of dry matter accumulation of stem and leaf while increase of translocation and distribution to tuber and enhancement of root to shoot ratios .Besides, the re-sults also indicated a trend of slow-fast-slow in dry matter accumulation at the growth stages .In 2:2 crop ratio the maxi-mums of dry matter accumulation of leaf and stem and translocation to tuber appeared earlier and there were lower dry matter accumulation and higher translocation compared with those in 3:2 crop ratio.Moreover, For the distribution of dry matter at the growth stages an upward trend to tuber and a downward trend to leaf and stem were observed ,with less a-mount under intercropping condition than sole cropping and in 2:2 ratio than in 3:2 ratio treatment.And the allocation of dry matter decreased less to stem than leaf .The dry matter distribution was leaf<stem<tuber.
