| Abstract: | Pitcher irrigation, used for several centuries in India,Pakistan and Tunisia ect.,is a water saving irrigation technique that water delivers from a pitcher,instulled under the ground near a tree or crop, to water the tree or crop. The technology was introduced and improved in 1993 at the Yuanmou Dry-Hot Valley Soil Conservation and Ecology Experinment Station. By testing, the hot pitcher, cement pitcher, was developed with success.It has Simple productive technology,lower cost, conveniet transportation, material got easily, long lifetime and rate of water delivery controlled easily advantages.The best economic technology indexes to make cement pitcher are: proportion of cement and sand is 1: 6;thickness is 2cm;form is cylinder and height equates diameter.The irrigation system, used cement pitcher, has following advantages:1. It is very water saving. By comparison of normal irrigation methods, it saved 80% of irrigation water.2. Technology is simple. Farmer can make cement pitcher and manage pitcher irrigation system by himself.3. The irrigation system established is no topography limit.The pitcher irrigation systems are suitable for spreadiny in the mountainous region of China. |
