临沭县山丘区旱地果园应用地下陶管渗灌技术，为果树提供了良好的水、肥、气、热条件，从而促进了果树的生长发育．不同渗径（渗径分别为１ｍｍ，２ｍｍ，３ｍｍ）渗灌和沟灌的试验对比表明，以１ｍｍ渗孔效果最好，每年增产苹果７２０４５０ｋｇ／ｈｍ２，节水２５１４ｍ３／ｈｍ２，增值１０４６４４５元／ｈｍ２．这一渗灌技术可作为我国北方旱地果园一种新的有效节水灌溉技术推广应用 The application of underground potting seepage irrigation technology in the dryland orchards in the hills and lush hills of Linshu County has provided fruit trees with good water, fertilizer, gas and heat conditions, thereby promoting the growth and development of fruit trees. The comparison of seepage irrigation and furrow irrigation with different seepage diameters (1mm, 2mm and 3mm respectively) shows that the best effect of 1mm perforation is that 720450kg / hm2 apples are added per year, water saving is 2514m3 / hm2, and the added value is 1046445 Yuan / hm2. This infiltration technology can be used as a new effective water-saving irrigation technology in dry orchards in northern China
