摘要

通过对陇中黄土高原半干旱区保护性耕作的定位研究

探讨了耕作方式对土壤渗透性能的影响。结果表明

免耕覆盖可以改善土壤结构性能

增加土壤有机碳含量

从而提高水分入渗能力。通径分析进-步发现

免耕覆盖对土壤渗透性能的改善作用是通过增加土壤非毛管孔隙度和有机碳含量来实现

而有机碳的作用也是通过土壤非毛管孔隙度间接达到的。

Abstract

A study of conservation tillage was conducted in the semi-arid area of the west Loess Plateau

Gan- su Province

to determine the eff ects of diff erent tillage measures on soil water infiltration.Results show that no-tillage with straw cover(NTS) can improve soil structure property

soil organic carbon content

and soil water infiltra tion.Path coeff icient analysis indicates an improvement of soil water infiltration due to the increase in soil macro-porosity and total organic carbon content.The contribution of total organic carbon to soil water infilt ration is also essential to soil macro-porosity.
