| 摘要: |
| 结合地上滴灌与渗灌技术优势,提出并进行了地下低压微孔管灌技术要素试验研究,结果认为,条件许可的地方工作压力选择1. 57～2. 35 kPa变水头,管径20mm,孔距60 cm,孔径0. 7mm为最佳管道技术要素;微孔管内的悬浮物质及固体物质易于清洗;管道各孔口出流均匀,土壤湿润理想;并可方便施肥。 |

| Technical elements of low-pressure underground pipe with micro-hole seep irrigation study |
|
|
| Abstract: |
| Combining advantages of drip-irrigation and seep irrigation,the experiment of the underground pipe with micro-hole seep irrigation was designed and conducted.The result showed that the working pressure could be chosen at 1.57-2.35 kPa,the pipe diameter 20 mm,the hole diameter 0.7 mm and hole interval 60 cm.The experiment proved that suspended substance and solid matter within the micro-hole pipe could be easily cleared,the flow from the micro-hole is well distributed with good soil infiltration.At same time,we could easily apply fertilizer. |
