稻田砂金开采生物复田技术研究

Research on Placer Gold Mining under Paddy Field-the Technology of Biological Field Recovery

从生物复田方面对稻田下砂金船采后的复田技术进行了系统的试验和分析研究。认为稻田下采矿金，复田后种植的农作物以大豆类作物为宜；生物复田全过程采用大豆—绿肥—杂交中稻—绿肥—杂交中稻种植模式，两年后稻田肥力可望达到或接近正常稻田肥力水平。

Based on the tests and analyses of engineering, the systematic research on biological field recovery technoeogy after being mined by dredger under the paddy field has been carried out. It is believed that the ratio, the overall Procedure of crops planting after biological field recovery can be the pattern sogbean -green manure - hybrid rice - green manure - hybrid rice. Ttus the fertility in the Paddy Should be the ferility in normal Paddy fied.
