目的
2
探究内蒙古砒砂岩区沙棘根土复合体抗剪特性对平茬复壮的响应,为该区固土保水和沙棘人工林可持续管理的生物力学策略优化提供理论指导。
方法
2
以内蒙古砒砂岩区8年生衰退型沙棘人工林为研究对象,对比平茬复壮1个生长季后与未平茬对照的根系分布特征及根土复合体抗剪特性。
结果
2
沙棘标准株根系0~1.5 mm径级的根数、根长、根表面积、根干重较未平茬分别提升9.29%,0.03%,8.35%和8.60%,表明平茬促进了细根的生长。在根系集中分布的土层中,根土复合体抗剪强度、残余抗剪强度分别增长了4.08%和28.80%,黏聚力和残余黏聚力与未平茬相比,平茬后分别增长了8.25%和50.64%,内摩擦角和残余内摩擦角分别增长了18%和25.57%;且平茬与未平茬沙棘根土复合体的抗剪特性、残余抗剪特性均优于素土,即含根土体的抗剪能力优于无根系土壤。
结论
2
平茬促进了细根的生长,细根旺盛的生命活动增强了根与土壤的相互作用,根土黏结性能改善。通过细根的网络胶结缠绕等,提高了平茬后沙棘根土复合体的抗剪强度,促进了土体的稳定性及抗侵蚀能力。
Objective
2
The response of the shear resistance characteristics of
Hippophae rhamnoides
root-soil complexes to stubble rejuvenation was examined in the Pisha sandstone area of Inner Mongolia. The aim was to obtain data for providing theoretical guidance for optimizing the biomechanical strategies used for conserving soil and water and sustainably managing
H. rhamnoides
plantations in this region.
Methods
2
The 8-year-old declining
H. rhamnoides
plantations in the Pisha sandstone area of Inner Mongolia were selected as research objects. The root distribution and shear characteristics of root-soil complexes were compared between a stubble rejuvenation group (after one growing season) and a control group.
Results
2
The number, length, surface area and dry weight of the roots with a 0—1.5 mm diameter in the root system of
H. rhamnoides
were 9.29%, 0.03%, 8.35%, and 8.60% larger, respectively, in the rejuvenation group than in the control group, indicating that stubble rejuvenation promoted the growth of fine roots. The shear and residual shear strengths of the root-soil complexes, the cohesion and residual cohesion, and the internal and residual internal friction angles were 4.08% and 28.80%, 8.25% and 50.64%, and 18.00% and 25.57% larger, respectively, in the stubble group than in the control group in the soil layer where the roots were concentrated. The shear and residual shear resistances of the root-soil complexes in the stubble and control
H. rhamnoides
were higher than those of plain soil; that is, the shear resistance of root-containing soil was higher than that of root-free soil.
Conclusion
2
Stubble rejuvenation promoted the growth of fine roots. The activities of fine roots increased the number of interactions between roots and soil, and the root-soil bonding strengthened. The shear strength of the
Hippophae rhamnoides
root-soil complex after stubble rejuvenation increased through the cementation of the fine root network and the entanglement of fine roots, which increased the stability and erosion resistance of the soil.
