摘要
关中灌区大多采用浑水灌溉发展条播地膜小麦,针对其灌水量大、灌溉水的利用率低的现实,分析了浑水膜缝畦灌入渗的主要影响因素——膜缝宽度、含沙率对浑水膜缝入渗的影响,建立了浑水膜缝入渗的数学模型,并通过实测资料对模型进行了验证。
Aimed at the fact that winter wheat in Guanzhong plain in Shaanxi province was irrigated principally with silty water, and the amount of irrigation was heavy but the utilizing rate of irrigation water was low, the paper, being linked up with the development of drilling and film-mulching wheat cultivation in recent years, analyzed the influence of width of film slit and silt concentration on the infiltration of the silty water via film slit. Moreover, it established the mathematical model being verified by the data of actual measurement.
