脱硫石膏与粉煤灰配施对盐碱土改良效果研究
Application of desulphurization gypsum with fly ash improves saline-alkali soils
为探究脱硫石膏与粉煤灰配施对干旱半干旱区盐碱土的改良效果,本研究以定边县盐碱土壤为对象,以紫花苜蓿为供试材料,进行盆栽试验,设置对照(CK)、添加脱硫石膏(1%、2%和4%;D1、D2和D3)、添加粉煤灰(1%、2%和4%;F1、F2和F3)以及添加脱硫石膏和粉煤灰混合物(0.5%+0.5%、1%+1%和2%+2%;DF1、DF2和DF3)10个处理,对土壤盐碱化指标、土壤养分含量及苜蓿生长进行研究和分析。结果表明:脱硫石膏可降低土壤pH,增加土壤总磷含量,提高苜蓿株高、生物量;SO42-、K+、Ca2+、Mg2+含量随脱硫石膏添加量的增加而增加。粉煤灰增加了土壤pH、SO42-、Ca2+和铁含量,降低了K+含量、苜蓿株高和生物量。脱硫石膏和粉煤灰配施降低了铁含量,增加了总磷含量,对苜蓿生长没有明显影响,说明二者配施对盐碱土的改良效果不佳。研究结果可为干旱半干旱区盐碱土改良以及煤基固废综合利用提供科学依据。
Saline-alkali soil is prevalent in arid and semiarid areas of Dingbian county. The aim of this study was to determine whether adding desulfurization gypsum, fly ash, or a combination of these two materials can improve saline-alkali soil. Pot experiments were conducted with alfalfa (Medicago sativa) growing in saline-alkaline soil with 10 treatments, including a control (CK), soil with the addition of desulfurization gypsum (1%, 2%, 4%; D1, D2, D3), soil with the addition of fly ash (1%, 2%, 4%; F1, F2, F3), and soil with the addition of mixture of desulfurization gypsum and fly ash (0.5%+0.5%, 1%+1%, 2%+2%; DF1, DF2, DF3). The salinity, sodicity, and nutrient profile of the soils and plant growth were analyzed. The results showed that the addition of desulfurization gypsum reduced the soil pH, increased the total phosphorus content in soil, and increased plant height and biomass. The contents of SO42-, K+, Ca2+, and Mg2+ in soil increased with the addition of desulfurization gypsum. The addition of fly ash increased soil pH, SO42ͨ-, Ca2+, and total iron contents, decreased the soil K+ content, and resulted in decreased plant height and biomass. The mixture of desulfurization gypsum and fly ash significantly reduced the total iron content and increased the total P content in soil, but did not significantly affect plant growth. The results indicate that, compared with the addition of desulfurization gypsum and fly ash to saline-alkali soil, the addition of desulfurization gypsum alone more effectively improved soil quality and promoted plant growth. These results provide a scientific basis for the improvement of saline-alkali soil and for the comprehensive utilization of coal-based solid waste in arid and semiarid areas.
