用 4种滴速在室内条件下进行了砖红壤水分入渗试验研究 ,采用烘干法和张力计法测定了不同时刻和不同深度处土壤的含水量 ,得到了砖红壤中水分迁移规律和适宜的滴灌速度 .结果表明 :在滴灌时 ,土壤中的水分主要受重力作用和毛细作用 ,使水分产生水平和垂直运动 ;滴灌停止后 ,土壤中的水分主要受热运动 (蒸发 )和土颗粒的结合力作用 ,使土壤中的水分逐渐均匀化 ;虽然砖红壤的细颗粒含量较高 ,但水分入渗速度快 ,因而应采用较大滴速进行滴灌 ,建议选择 15～ 2 0mL/min的滴速对短期生长的蔬菜、瓜果进行滴灌较为适宜 ,既可满足充分供水 ,又可减少渗漏损失 The water infiltration of brick red soil was tested under four indoor drip rates. The moisture content of soil at different times and depths was determined by the drying method and the tensiometer method, and the water migration rules in the brick red soil were obtained. Of drip irrigation.The results showed that the moisture in the soil was mainly affected by gravity and capillary action during drip irrigation, which made the water produce horizontal and vertical movement. After the drip irrigation stopped, the moisture in the soil was mainly affected by the combination of heat movement (evaporation) and soil particles Force, so that the soil water gradually uniform; Although the red brick red soil high content, but the water infiltration speed, and therefore should be a larger drip drip, it is recommended to choose 15 ~ 20mL / min drip rate For short-term growth of vegetables, fruits drip irrigation is more appropriate, can meet the full water supply, but also reduce leakage losses
