组合施肥技术对黑土肥力影响的研究

采取定位试验的方法研究了组合施肥技术对土壤有机质、氮、磷的影响。结果表明,组合施肥较单施化肥土壤有机质含量增加1.8～3.3g/kg;土壤全氮增加0.05g/kg,速效氮(除Ⅱ处理外)增加6.6～44.6mg/kg;土壤全磷增加0.15～0.29g/kg.速效磷增加15.68～37.21mg/kg。土壤有机质增量为0.6～23g/kg;土壤氮素增量全氮增加0.002～0.25g/kg,速效氮增加11.6～39.4mg/kg;土壤磷素增量全磷增加0.09～0.24g/kg,速效磷增加23.59～57.28mg/kg。在保持土壤肥力有所提高的情况下,玉米大豆两年平均产量提高7.7％～17.3％,净收入提高19.4％～37.3％,由此可见,组合施肥技术应用前景广阔。     

Assessment of Groundwater Quality and Contamination from Uranium-Bearing Black Shale in Goesan–Boeun Areas, Korea

This study was initiated to identify the impact of metals and uranium enriched soil and black shale in groundwater quality and contamination. From a Piper diagram, groundwater was classified into four types as (Ca+Mg)–HCO₃ type, (Ca+Mg)–SO₄ type, the mixed type of these two and Na–HCO₃ type, reflecting the complicated nature of geology of the study area. Silicate weathering appeared to be the major water–rock interaction. In groundwater, metals including Cr, Pb, Cu and V, previously identified as being enriched in soils and black shale, were much lower in concentrations than Korean and US EPA drinking water guidelines. Instead, Fe and Mn caused major water-quality problems. In the artesian groundwater from an abandoned uranium mine, the uranium concentration was 21.3 µg L^–1, slightly higher than EPA guidelines of 20 µg L^–1. Heavy metals in groundwater appeared to be controlled mostly by sorptions on to Fe- and Mn-oxyhydroxides. They could be remobilised in groundwater with changes of pH and Eh conditions due to acid mine drainage from black shale or the recharge of fresh water. Uranium would be associated with carbonate and sulphate complexes in groundwater. Because of the remaining water-quality problems in the study area, we suggested containment of identified mine wastes, considering remedial measures for local problems with Fe and Mn, continuous monitoring of groundwater and developing groundwater from deep aquifers.     

A new direction for the development of the paper industry

-In order to reduce the increasingly serious environmental impact caused by wastewater from the paper industry, the municipality of Jinan plans to adopt a specialized production technology. The new technology will centralize pulp production and decentralize paper production. It is predicted that the new technology will greatly reduce the environmental effects of the paper industry. Perhaps it is a new direction for the development of the paper industry in China.
