摘　　要：以何首乌为材料,研究了覆盖黑色地膜与无色地膜对何首乌生长及其田间杂草防控效果的影响。结果表明:覆盖黑色地膜对何首乌田间双子叶杂草防控效果达到73.78%,覆盖无色地膜对何首乌田间双子叶杂草防控效果达到47.02%。覆盖黑色地膜和无色地膜的小区中均没有发现单子叶杂草,不覆盖地膜的对照区有13.91%的单子叶杂草。覆盖黑色地膜和无色地膜的藤鲜重和最大块根鲜重均比不覆盖地膜要高。说明覆盖黑色地膜能有效防控杂草种子的萌发和杂草生长,无色地膜也具有一定的防草效果。覆盖地膜对何首乌藤鲜重和最大块根生长影响显著。The effect of plastic film mulch on growth of Polygonum multiflorum and weed control in field were investigated in the present work. The result showed that： the control effect of dicotyledonous weeds covered with black plastic film was over 73.78% , while that with colorless plastic film was just 47.02%. No monocotyledonous weed had been found with black or colorless plastic film mulching, however it was 13.91% in mulching-free field. The fresh weight of rattan and maximum tuber of Polygonum multiflorum under plastic film mulching were higher than that of mulching-free. The available data proved that the effect of black film on weed control is obvious, and colorless film also has a certain effect. The fresh weight of Polygonum multiflorum Thunb and the growth of its maximum root tuber were increased apparently under plastic film mulching.
