利用风化煤改良盐碱湿地的初步研究

经试验研究证明用风化煤改良盐碱湿地,种植小麦增产效果明显,可以解决风化煤堆积占地影响环境的问题.试验证明,盐碱湿地施入风化煤后,可以降低盐碱湿地土壤的容重,增加孔隙度,提高土地温度,缩小膨胀率,明显地改善了土壤的物理、化学性质,促进土壤中微生物的活性,从而有利于土壤的保温,保墒,有利于养分的转化,为作物生长创造良好的土壤环境.

The Initial Results from Research on Soil Improvement Utilising Weathering Coal

Experiments shows that the wheat production yield in saline-Alkali field will be increased considerably by utilizing weathering coal properly. Utlizing weathwcathering coal can decrease the marsh content of soil, reduce density and swelling value, increase porosity of soil. Weathering coal could also improve the physical and chemical properties, promote micronial activities of soil. It could raise soil temperature, enhance the transformation of soil nuturients and create a good soil environment for crop growth as well. On the top of these, utilizing weathering coal properly in saline-Alkali field will straighten out the inviroment polution caused by piling up weathering coal in fields.
