不同类型不同密度的水稻（Oryza sativa）与一定密度的稗草（Echinochloa crusgalli）混合种植，结果显示：不同处理对稗草株高的影响不显著；低密度水稻处理的稗草分蘖数显著高于其它密度；高密度处理的稗草叶面积指数显著低于其它密度；对稗草生物量的影响各处理间差异显著，随着水稻密度的增加，稗草生物量逐渐减少，稗草的生长速率逐渐降低；稗草的相对生长率也随水稻密度的增加而降低，但差异不显著；不同类型水稻对稗草的抑制效应不明显，但相对来说穗数型品种的抑制作用稍强一些。

Through mixtural planting of barnyardgrass of a certain density with rice at three different densities, it was found that the plant height difference of barnyardgrass was not significant in different treatments;the tillering numbers under lower rice density were greater than others; the leaf area indexes under higher density were significantly less than others and there was a significant difference in the dry matter weight between different treatments.As the rice density increased,the growth rate of barnyardgrass decreacsed,and the relative growth rate of barnyardgrass decreacsed too,but not significantly.The restricting effect of different rice types on barnyardgrass growth was not significantly different.
