在大田条件下,以等行距(0.8 m)和宽窄行(1.0 m+0.6 m)木薯单作为对照,研究了等行距和宽窄行木薯间作花生对木薯生长、薯块品质和产量的影响.结果表明:宽窄行单作与等行距单作间木薯的生长、薯块品质和产量均差异不大;与单作比较,间作木薯的生长、薯块品质和产量均受到较大抑制;与等行距间作比较,宽窄行间作有助于提高木薯的根冠比、相对生长率、群体生长率、叶面积指数、鲜薯干物率和淀粉含量以及鲜薯、薯干和淀粉产量,且宽窄行间作的木薯偏土地当量比略高于等行距间作的,表明木薯间作花生模式以宽窄行为优.%The single cropping of cassava with equal row spacing (0.8 m)or wide and narrow row spacing (1.0 m+0.6 m) was taken as the control,the effects of equal-row-spacing and wide/narrow-row-spacing cassava-peanut intercropping on the growth,quality and yield of cassava were studied under the field condition. The results showed that there were no great differences in the growth,quality and yield of cassava between two single cropping modes. In comparison with the single cropping of cassava, the cassava-peanut intercropping greatly inhibited the growth,quality and yield of cassava. As compared with the equal-row-spacing cassava-peanut intercropping,the wide/narrow-row-spacing cassava-peanut intercropping could increase the root-shoot ratio,relative growth rate,group growth rate,leaf area index,dry matter rate and starch content of fresh tuber,and yield of fresh tuber,dry tuber and starch of cassava. The partial land equivalent ratio of cassava in wide/narrow-row-spacing intercropping was slightly higher than that in equal-row-spacing intercropping. The above results indicate that wide/narrow-row-spacing cassava-peanut intercropping is the best.
