1) continuous infiltration
连续入渗
1.
The nitrate nitrogen transport and distribution characteristics of intermittent infiltration under surge fertigation were researched based on indoor experimental data, the connection between nitrate nitrogen distribution and soil water content was founded, and contrasted with continuous infiltration.
通过室内土壤灌施间歇入渗试验,研究了灌施条件下波涌灌溉土壤间歇入渗硝态氮的运移与分布特性,分析了硝态氮分布与土壤含水量的关系,并与灌施条件下土壤连续入渗进行了对比,为进一步研究施肥条件下波涌灌溉土壤间歇入渗溶质运移规律奠定了基础。

灌溉入渗补给系数
coefficient of irrigation recharge into ground water
guan’gai rushen buji xishu灌溉入渗补给系数(eoeffieient of irriga-tion reeharge into ground water)灌溉水补给地下水的数量指标,是灌溉入渗补给地下水的量与灌溉水量之比。影响因素主要有灌溉定额,土壤含水量、土壤质地、地下水埋深、植被情况和气候条件等。 灌溉水入渗,只有在土壤含水量超过田间持水量时,多余的水才能补给地下水。一般在相同的条件下,灌溉定额小、土壤质地粘重与植被差时,灌溉入渗补给系数小(如果灌溉定额很小,可能无入渗补给);反之则大。田间的地下水埋深大(即非饱和带上壤的厚度较大),故灌溉入渗补给系数小;反之亦然。当引外区的河水或井水时,由灌溉入渗补给系数算得补给地下水量,作为本区的地下水补给量。引河水灌溉,一般灌水定额较大,灌溉入渗补给系数大;引井水灌溉,灌水定额较小,此系数亦小。(金光炎)
