对4种暖季型草坪草的固土性能进行了力学试验比较.对根系抗拉强度和土壤抗剪强度进行测定,结果表明:不同草坪草根系具有不同的抗拉强度,百喜草根系平均抗拉强度34.64 MPa>假俭草27.58 MPa>狗牙根26.31MPa>结缕草22.82 MPa;不同坡度与植物种类影响着根系对土体抗剪强度的强化作用;运用加权平均法综合评价分析4种暖季型草坪草土体抗剪强度,排序为百喜草>假俭草>结缕草>狗牙根.

A mechanical test on soil-reinforcement performance of four kinds of warm-season turfgrass was carried out, the tensile strength and shear strength of roots system of four warm-season turfgrass were measured. The tension test results reveal that different roots had different tensile strength, and the avrage tension strength of four kinds of warm-season turfgrass were proioritized from high to low as follows: Bahia grass 34.64 MPa>Common Cetipede grass 27.58 MPa>Bermuda grass 26.31 MPa>Zoysia 22.82 MPa; the soil shere test shows that different gradient and species can directly affect the strengthening action of roots syatem on shere strength. A comprehensive evaluation with weighted average method was used to analyze the shere strength of four warm--season turfgrass, and the results indicate that the order from high to low is Bahia grass>Common Cetipede grass>Bermuda grass>Zoysia.
