滴灌时每个滴头湿润范围的大小、深浅以及浸润的快慢都与土壤的结构、初始含水量、滴水时间、滴水量等因素有关。本文根据我国滴灌的实际情况,以大量的田间实测资料为基础,采用较简便的公式,从几个方面概括了实验中所得的关系,一、滴灌时土壤湿润锋运移速度。二、不同土壤在同一滴水量时的浸润形状。三、不同滴水量下的土壤浸润球体。四、滴灌浸润球体内土壤水分的分布。为滴灌系统设计及管理运用好滴灌系统提供了依据。
The drip irrigation drip wet range size, depth and infiltration speed and soil structure, initial water content, drip time, drip and other factors. Based on the actual situation of drip irrigation in China and based on a large number of measured data in the field, this paper summarizes the experimental results from several aspects by using simpler formulas. First, the transport speed of soil wetting front during drip irrigation. Second, different soil infiltration in the same drip shape. Third, the amount of drip infiltration of the soil under the soil. Fourth, drip irrigation infiltration of soil moisture distribution. Drip irrigation system for the design and management to use good drip irrigation system provided the basis.
