In this paper, based on the field single-point infiltration experiments of surge irrigation and continue irrigation at Guan Zhong, Shaanxi, the influence of surgeimgation technical parameters upon the red- ucing infiltration effects of intermittent infiltration in midium loam is analysed and the reasonal surge irrgation technical parameters that are suitable for midium loam are put forward from the single-point infiltration characteristics. The results can be used as reference for the field irrigation experiments...

The results can be used as reference for the field irrigation experiments and management under surge inigation in the similar districts

本文以大田实测连续及间歇单点入渗对比试验为依据,针对陕西关中土类之一搂土,分析了间歇灌灌水参数对间歇入渗减渗效果的影响。从单点入渗的角度,提出了适合中壤质地土壤的合理间歇灌灌水技术参数,可供类似土壤质地地区间歇灌大田试验及用水管理参考。

Intermittent irrigation is a new surface irrigation technology for saving water, The paper analyses the influence on the results of intermittent infiltration and infiltration reduction by the factors of initial soil moisture, soil structure and watering parameters based on 141 groups of farmland test data of continuous and intermittent single-point infiltration and in the light of middle loamy soil in Guanzhong region of Shaanxi Province. The results show that the degree of initial soil moisture influences mainly the initial stage of infiltration process, but a little influence to the results of infiltration reduction; infiltration reduction rate is getting smaller along with the increase of unit weight of surface soil; watering parameters have different effects on infiltration reduction results, among which, the effect on circulation ratio is the maximum.

间歇灌是一种新的地面节水灌溉技术。本文以141组大田连续及间歇单点入渗试验资料为依据,针对陕西关中地区中壤质地土壤,分析了土壤初始含水量、土壤结构及灌水参数等因素对间歇入渗减渗效果的影响。结果表明,土壤初始含水量的大小主要影响入渗过程的初始阶段,对减渗效果影响甚微;随着表土容重增大,减渗率减小;灌水参数对减渗效果有不同程度的影响,其中循环率影响最大。

The infiltration experiment of point source irrigation reveals that two kinds of boundary condition may occur, depending on the drip flux. One is non\|pond infiltration formed by insufficient flux, whereas another is pond infiltration with moving boundary. The characteristics of these two boundary conditions and the relationships among drip flux, irrigation duration, wetting front and distribution of soil moisture are analyzed in this paper. It concludes that the wetting front rate is one of the important parameters...

The infiltration experiment of point source irrigation reveals that two kinds of boundary condition may occur, depending on the drip flux. One is non\|pond infiltration formed by insufficient flux, whereas another is pond infiltration with moving boundary. The characteristics of these two boundary conditions and the relationships among drip flux, irrigation duration, wetting front and distribution of soil moisture are analyzed in this paper. It concludes that the wetting front rate is one of the important parameters of drip irrigation and the best rate in less than 1 0.

由不同质地土壤的点源入渗实验 ,得出了在不同滴头流量情况下 ,实际滴灌可以形成两种入渗边界 ,边界一是非充分供水点源入渗边界 ;边界二为变边界积水点源入渗边界 .本文对两种边界条件特点及其滴头流量、灌水时间、湿润锋、含水量分布等之间的关系进行了分析 ,认为湿润比可以作为确定滴灌灌水参数的指标之一 ,对于实验滴灌的适宜湿润比以小于 1 0为宜
