摘  要:
对试验区柠条锦鸡儿根系进行群根拉伸试验。结果表明,在相同的根径下,不论根系数量的多少,根系的抗拉力和抗拉强度具有随长度的增长而递减的趋势,且其递减的幅度较小;不论根长和根径如何变化,随根系数量的增加抗拉力均有较大幅度的提高。

摘  要:
The multiple roots tensile tests of Caragana korshinskii were carried out in the testing areas.Results showed that when the C.korshinskii had the same root diameter,whether root quantity was more or less,the root tensile resistance and root tensile strength decreased with increase of root length,and the decreasing extent was lower.Whether root diameter and root length changed or not,the root tensile resistance increased greatly with increase of root quantity.
