We conducted root box, cylinder column and field tests to examined the relation between root structure and soil holding abilities of several cover crops. Among 10 cover crops, Kentucky bluegrass, tall fescue, creeping red fescue, perennial ryegrass, orchardgrass, reed canarygrass, centiped grass, bahiagrass, weeping lovegrass and white clover, centiped grass showed the highest soil holding ability. Its soil holding ability was closely related with the root growth, especially the distribution of roots in soil and rooting form which comes out of the nodes.

通过根箱、圆柱和田间试验，研究了几种覆盖作物根系结构与土壤持土能力的关系。在10种覆盖作物中，肯塔基州早熟禾、高羊茅、匍匐紫羊茅、多年生黑麦草、鸭茅、草芦、假俭草、百喜草、垂盆草和白色三叶草、假俭草的持土能力最强。其持土能力与根系的生长密切相关，特别是根系在土壤中的分布和从节位上出来的生根形态。
