| 摘 要： | 高粱［Ｓｏｒｇｈｕｍｂｉｃｏｌｏｒ（Ｌ．）Ｍｏｅｎｃｈ］又名蜀粟，有悠久的栽培历史和独特的抗逆性及适应性，在我国旱作农区，凡不适于玉米、小麦栽培的干旱或半干旱瘠薄耕地，种植高粱均能获得较高和较稳定的籽粒产量［１］，高粱这种抗逆性较强的特点与其有发达的根系系统有关，但由于研究方法和手段的原因，在国内对高粱根系研究开展的还较少，本试验在大田条件下系统研究高粱根系生长发育规律，并与玉米根系进行比较，为进一步开展高粱抗逆性研究和抗旱育种提供依据。１ 材料和方法试验于１９９６年在中国科学院石家庄农业现代化…

| Abstract: | By taking soil cores at the different growth stages, the distribution, weight, and length of sorghum root system were studied, and models were established to simulate its total root length and weight increasing patterns. In addition,by comparing sorghum root system with maize root systems, the correlation of root systems with the high drought-resistance of sorghum was testified. |

| Keywords: | sorghum root system dynamics drought-resistance. |
