稻壳暗管在改良低湿地中的应用

Rice Husk Subsurface Pipe in theImprovement of Lowland

黑龙江省宝清县三江水利试验站稻壳暗管排水资料表明，稻壳暗管既能排出地表残留水、水壤过湿水分稻壳腐乱后，又能增加上壤有机成分，改善作物生态环境，促进作物生长，提高作物产量，是改良低湿地有效的技术措施。

Based on the in-situ data obtained in Sanjiang Hydraulic Test Station in BaoqingCounty of Heilongjiang,an analysis is made,and the results show that rice husk subsurface pipe can drain both superficial residury water and soil supersaturation waifer,andwhen rice husk decayed,organic element in soil can be enriched and ecosystem can be improved. Rice husk subsurface pipe can be an effective engineering approach for the improvement of lowland.
