摘要:
本文通过对宝鸡峡灌区波涌灌和连续灌前后大量土壤取样的粒度组成分析认为，灌水对农田土壤粒度组成的时空分布的影响是长期效应。波流灌灌水技术参数，除入沟、畦流量外，放、停水时间及循环率对土壤的粒度组成没有明显的影响。灌水过程中入渗携带的极少细颗粒并不是波涌灌表层土壤导水率降低的原因。
Abstract:
More than 200 soil samples under surge flow and cntinuous flow irrigation in Baoji Gauge were analyzed. The space-time distribution of soil mechanical composition in agri-field was affected by irrigation over a long period time. The results show that in the case of surge irrigation, the irrigation parameters-on-time, off-time and cycle rate-had no obvious effect on the soil mechanical composition except the water flux mentioned above.As the change of the soil mechanical composition was very limited, this change cannot be the reason of the water saving natural of surge irrigation.
