| 摘 要： | 采用根箱方法模拟研究了玉米、大豆间作条件下两种作物根系形态特征与空间变异。结果表明：间作有利于玉米、大豆根系的生长，与单作相比，间作在不同土层中作物根干质量相应增加，根冠比增大，比根长明显增加。因此，玉米、大豆间作的根系系统优越于各自的单作，可通过两种作物根系的互补作用，利用作物自身的潜力，提高空有效性。 |
| 关 键 词： | 间作 玉米 大豆 根系形态特征 空间变异 互补作用 根干质量 根冠比 根长 |

| Abstract: | The Effects of intercropping of maize and soybean of the root morphology character were studied by rhizobox method.The results showed that the intercropping of maize and soybean stimulated the root growth of both maize and soybean,i.e.,with contrast to monocultures,the root dry weight and root/shoot ratio in various soil layer in intercropping system were high.The maize and soybean specific root length showed significant increase in intercropping system.Therefore,the root system of intercropping of maize and soybean in superior to that of monoculture respectively.The mutual response of two crop roots can enhance the validity of crop space. |
| Keywords: | intercropping maize soybean root morphology character |
