| Abstract: |
| According to water infiltration characteristics and irrigation effect of ridge tillage using furrow irrigation, the evaluation indexes of irrigation quality of traditional surface irrigation was improved, an index system including irrigation uniformity, water storage rate and irrigation water use efficiency, the ridged body wetting degree was established for irrigation quality evaluation of this irrigation techniques. To reduce measuring work and facilitate the practical application, the index calculation method was simplified. This evaluation index system is scientific and reasonable, and its simplified calculation method is simple and feasible verified by using water content data measured in field of the case study. |
