| 中文摘要: |
| 特制陶罐埋入土中盖膜并盛水,通过罐壁微孔,使水分缓慢渗入土中,试验表明,该技术不形成径流和深层水分渗漏,不造成土壤板结,遇旱可及时补水,并将作物需要的养分和农药溶于水中,在地膜覆盖下,很少发生地表蒸发。在年降雨量350mm左右的旱山区,利用“121”雨水集蓄工程中的窖水,种植西瓜、籽瓜、西红柿、辣椒等获得成功,其效益与种植地膜粮食相比,高3.5～9.8倍,而成本仅为软管滴灌的1/3。 |
| 英文摘要: |
| Water stored in the specially-made earthenware pots buried in the soil and covered with plastic mulch slowly penetrates into soil through the micro-apertures on the pot wall and moistens the soil around the root zone. The results showed that this irrigation technique does not cause surface runoff , water loss through deep penetration and prevent soil surface crust. In drought season, it provides efficient supplementary irrigation, and evaporation is minimized by mulching. Furthermore, fertilizers and chemicals can be added in the irrigation water and transferred to the root zone if necessary. In the mountain areas, with 350 mm annual rainfall, watermelon, seeded watermelon, eggplant, tomato and pepper have been successfully planted by using water stored in the water-harvesting pools. Compared with grain production under mulching, the output increases 3. 5-5. 9 times greater while the input is only about 1/3 of drip irrigation system. |
