不同种植密度下草本植物根系生长对土壤侵蚀阻力的影响

Shuitu Baochi Xuebao
目的为探讨不同种植密度下植物根系的固土减蚀效应。方法以黄土高原典型草本植物黑麦草（Lolium perenne）和紫花苜蓿（Medicago sativa）为研究对象，采用100、300、500株/m2 3个种植密度，研究不同种植密度下植物根系生长对土壤侵蚀阻力的影响。结果试验期内，植物根系特征整体呈先快速增长后缓慢下降趋势，黑麦草和紫花苜蓿的根系特征分别在中、高密度种植样地生长最佳。在根系生长的驱动下，土壤有机质呈不断增长趋势，黑麦草和紫花苜蓿样地的土壤有机质分别在中、高密度种植下增量最大，分别增长2.
