渗灌是节水农业中一类有效的灌溉方式。实践证明渗灌具有明显的节水高产效果,但以往在生产中推广应用的渗灌方法,由于其设备复杂、投资大、用工多、操作不便等缺点,往往存在推而不广、用而不久、效益不佳的状况。作者在实践中曾探索设计出一种简单易行,行之有效的渗灌方法,即瓦道暗灌法。该方法具有诸多优点,其综合经济效益达30％以上,是一种值得推广的的实用技术。 1 瓦道暗灌法的操作规程 利用传统烧制的盖房用的泥瓦为材料,上两片对扣联接,水平铺设于土壤作层中,组成通水渗水管道。瓦道底层距地表深度10～30cm。具体深度可根 Seepage irrigation is an effective irrigation method in water-saving agriculture. It has been proved that seepage irrigation has significant water-saving and high-yielding effects. However, the conventional seepage irrigation methods that have been widely applied in production are often short-lived due to complicated equipment, large investment, laborious labor and inconvenient operation. , The poor efficiency of the situation. In practice, the author has explored to design a simple and effective seepage irrigation method, that is, the method of shimming through the valley. The method has many advantages, its comprehensive economic benefits of more than 30%, is a practical technology worth promoting. 1 Wavow dark irrigation method of operating rules The use of traditional burial mound for the use of clay roofing materials, the two on the buckle connection, horizontal laying in the soil layer, the composition of water seepage pipe. The bottom of the tile is 10 ~ 30cm away from the ground. Specific depth can be root
