秸秆生物反应堆对滨海盐碱土的改良培肥效果

Effects of Straw Biological Reaction Pile Technology on Improvement and Fertility of Coastal Saline-alkali Soil

为充分利用滨海土壤资源,发展沿海滩涂高效农业,采用挑台建造塑料大棚并利用秸秆生物反应堆技术,在乐亭县进行了渤海湾地区盐碱地改造及高效农业配套技术研究。结果表明:挑台建棚秸秆生物反应堆技术能改良、培肥滨海盐碱土,与挑台淋盐方法相比,显著改善土壤孔隙状况,减小容重,降低土壤酸碱度,土壤脱盐达到轻盐化～非盐化水平,为发展高效农业建立了良好基础。

The deep ditch plus straw biological reaction pile technology was tested to take full advantage of coastal soil resources and to develop high-efficiency agriculture in coastal areas. The results showed that the deep ditch plus straw biological reaction pile technology could fertilize coastal saline-alkali soil, significantly improve soil porosity, decrease soil bulk density and reduce soil pH for light salinization and non-salinization of coastal saline-alkali soil compared with the deep ditch model.
