土壤结皮 meaning in Chinese
soil crust
Examples
- Pam is able to cohere strongly the soil particles at the surface to form bigger aggregates , therefore to significantly increase infiltration and reduce soil erosion
Pam能明显地黏结土壤表面的颗粒，形成团聚体，阻碍土壤结皮的形成，减少土壤侵蚀。 - Scanning electric microscope ( sem ) photographs were used to examine the structure of surface soil experienced a rainstorm , for the purpose of understanding the mechanism of soil crusting . it approved that soil crusting consists of depositional crust and structural crust . the curves of infiltration with time revealed four stages of crust formation
用电子扫描显微镜( sem )照片对比了土壤表面结构，分析了土壤的结皮机理，可以认为土壤结皮是由结构结皮和沉积结皮构成，入渗量与时间的历时曲线反映了结皮的四个形成过程。 - On the basis of analyzing infiltration process to different soil and water conservation tillage measures type , a increasing infiltration r ates model for different soil and water conservation tillage measures type by using water balance equation is woke out . 4 . accumulation depth and soil crust have a better affect to soil initial stage infiltration rates and a little affect to soil stable infiltration rates
( 4 )积水深度和土壤结皮对初始入渗速率影响较大，对稳定入渗速率影响不大，随着积水深度和结皮厚度的增大，这种情况尤为显著，如在积水深度为5cm和3cm情况下，稳定入渗速率在黄土高原沟壑区分别为0 . 57mm min和0 . 56mm min ，在黄土丘陵沟壑区分别为0 . 94mm min和0 . 93mm min ，两者相差甚微。
