通过田间试验探讨了复合改良制剂、草炭、风化煤等腐植酸类物质施用对盐碱化中低产田土壤理化性质及生长作物的影响,结果表明:复合改良制剂、草炭、风化煤施用对土壤理化性质均有积极的影响,与对照相比达到显著水平。玉米产量的方差分析表明,复合改良制剂处理与草炭、风化煤等处理差异显著,与对照差异极显著,增产率均达到30.67%以上。
The field experiment was carried out to study the effects of humic acids such as compound modified preparations, peat and weathered coal on soil physical and chemical properties and growing crops in middle-low salinity and saline-alkali soil. The results showed that the effects of compound modified preparations, peat and weathered coal on soil physical and chemical Both have a positive impact on the nature, reaching a significant level compared with the control. Analysis of variance of corn yield showed that there was significant difference between the treatment of compound improved preparation and peat, weathered coal and other treatments, and the difference was significant with the control, with the yield increasing rate reaching over 30.67%.
