本试验研究了施用脱硫废弃物对盐碱地林草生长发育及土壤性质的影响。结果表明:施用脱硫废弃物能显著改善土壤的理化性质,促进林草的生长发育,但在不同林草品种间存在差异性。土壤改良效果与栽植林草间存在交互作用,不与脱硫废弃物的施用量呈正相关,以15 t/hm2的施用量效果最佳。
The experiment studied the effects of applying desulphurization waste on the growth and soil properties of forestland grassland in saline-alkali land. The results showed that the application of desulfurization waste can significantly improve soil physical and chemical properties, and promote the growth and development of forest and grass, but there are differences in different forest grass varieties. There was interaction between soil improvement effect and planting forest and grass, and it was not positively correlated with the amount of desulfurization waste. The best application rate was 15 t / hm2.
