    摘要:

    为探明含碳与含硫改良物料对苏打盐化土的改良效果,利用含硫物料硫酸亚铁(FeSO 4)、硫酸铝 Al2(SO4)3和含碳物料[腐植酸改良剂(DS-1997)、风化煤]作为改良材料,采用田间定位试验,研究苏打盐化土在施用不同改良物料条件下土壤 pH值、EC值、ESP值、土壤盐基离子、土壤养分的变化规律,以及饲草玉米对土壤改良效果的响应。结果显示,4种物料均能较对照(CK)显著降低土壤 pH值、ESP值,交换性 Na +和水溶性 Na +含量,分别降低了 2.87%~5.39%、38.72%~75.21%、52.33%~ 78.14%和 89.54%~96.61%,均以风化煤处理降低幅度最大。施用风化煤和 DS-1997能显著提高土壤有机质和有效磷含量,风化煤处理较 CK分别提高了 88.51%和38.70%,DS-1997处理较 CK分别提高了 63.18%和33.33%( P<0.05)。各改良物料均可显著改善玉米生物性状,但各改良剂处理间无显著性差异。综合分析,风化煤在苏打盐化土中改良效果最好,可作为内陆苏打盐化土的最佳改良物料。

    Abstract:

    Aimed at screening effective soil amendments to the soda salinesoil,a stationary experiment was carried out in the field. FeSO4,Al2(SO4)3,weathered coal and humic acid amendment(DS -1997)were applied to study the effects ofdifferent soil amendments on maizebiomass,soilpH,EC,ESP value,soil salt and nutrientcontains,in contrast no soilamendment was applied. The results showedthat,compared with CKtreatment,the application of the four amendmentssignificantlydecreasedsoilpH,ESPvalue,thecontents ofexchangeNa + and watersoluble Na+contentsby2.87%~5.39%,38.72%~75.21%,52.33%~ 78.14% and 89.54%~96.61%,respectively,all of them showed the greatest decrease with weathered coal. Soil organic matter and Olsen-P contents showed significantly increase with the application of weathered coal and DS-1997. Compared with CK treatment,the SOM and Olsen -P contents increased by 88.51% and 38.70% inweatheredcoal,by 63.18% and 33.33% in DS -1997( P<0.05). Different amendments could improve maize biologicalcharacteristics,there were no significant differences among four amendments,compared with CK treatment. In summary,the application of weathered coal could significantly improve soda salinizedsoil,by decreasing soil pH and ESPvalues,improving soil saltcomposition,increasing soil nutrient content and maize yield.
