摘　　要：提出一种派酶-土壤-黑麦草根系复合体,即在含派酶土壤中加入黑麦草根系。探讨不同含酶量及含根量下复合体的抗剪强度,并在具有不同含酶量的土壤中种植黑麦草种子。由试验结果可知:黑麦草种子可以在含派酶土壤中存活并生长;在考察范围内,复合体的抗剪强度随含酶量的增加而增大,φ值随含酶量的增加先增大后减小。In order to understand the effect of Perma zyme on soil shear strength, a type of Perma zyme stabilized soil-root composite was proposed, which can be defined as mixing the roots of ryegrass into the soil which contains Perma zyme. The shear strength of the composite was investigated in terms of various Perma zyme and roots content of composite. Seeds of ryegrass were cultivated in soil with different Perma zyme content. Results proved that seeds of ryegrass can survive and grow well. It was found that the shear strength of PSSRC increased with the increase in Perma zyme content. The value of φ first increased and then decreased with the increase in Perma zyme content.
