摘要:
采用土柱淋溶模拟试验,研究长效碳铵及普通碳铵在土壤中的分解特性,以考察长效碳铵固碳的实际可能性.试验表明:在施用长效碳铵和普通碳铵后的1个星期左右,两者在土壤中的HCO-3,CO2-3离子质量浓度基本相同,且主要集中在土壤表层.2个星期后,施用长效碳铵的土壤中HCO-3,CO2-3离子质量浓度都明显高于相应的普通碳铵.结果可知在土壤固碳方面长效碳铵要优于普通碳铵.
Abstract:
Ammonium bicarbonate(ABC)and long-effect ammonium bicarbonate(LEABC), are water soluble carbon compounds. They can percolate into the earth’s aquifer layer, and eventually be neutralized by the alkaline components in the aquifer. Therefore some of the carbon compounds in it can be permanently fixed in the earth in stead of returning into atmosphere as greenhouse gas-CO2. The percolation characteristics of ABC and LEABC is studied in this paper. Simulative soil columns, which were fertilized with ABC and LEABC respectively, were used to research the distribution and decomposition of the two fertilizers in soil under the natural condition in laboratory. It is found that concentrations of bicarbonate in soil columns fertilized with ABC and LEABC are almost the same at the same depth of the soil after 7 days. But after two weeks, obvious differences between soil columns fertilized with LEABC and ABC can be found. The concentration of the former is much higher than that of the latter at the same depth. The results indicate that LEABC is better than ABC to sequestrate CO2.
