摘　　要：对金水梨树进行工程渗灌和的漫灌对比试验结果表明 :工程渗灌能节水并可防涝 ,可增加土壤孔隙度 ,提高土壤养分含量 ,增加吸收根数量 。The effects of subsoil irrigation and wild flooding irrigation were compared on pear trees . The results indicated that subsoil irrigation could save water and prevent waterlogging and that it could increase soil porosity and soil nutrient content.The technology could also increase the number of absorbing roots and promote the growth of trees.
