中文摘要:
      为寻求适宜内蒙古河套灌区中度盐渍化土壤改良产品,选择了具有代表性的4种土壤改良剂和3种抗盐碱专用肥,通过田间及室内试验研究施用各土壤改良产品对土壤含盐量、土层贮盐量及油葵产量构成等因素的影响。结果表明:施用各种土壤改良产品处理均显著优于对照处理;其中抗盐碱专用肥在提高作物出苗率、保苗率及增产方面占优,而土壤改良剂在土壤脱盐及降低土壤碱性方面更具优势;在各种改良产品中丹路菌肥(T5处理)在提高葵花出苗率、保苗率及增产方面效果最佳,在土壤脱盐及降低土壤碱性方面也较为突出;磷石膏(T1)处理在土壤脱盐及降低土壤碱性方面效果最佳,故将丹路菌肥和磷石膏作为本研究筛选结果,建议在盐渍化土壤改良中推广使用。
Abstract:
      The effects of four kinds of soil ameliorants and three kinds of anti-alkali special fertilizers on soil salt content, salt storage of soil layer, yield components and dry matter quality of oil sunflower were analyzed in order to screen the suitable materials for improving the moderately salinized soil in Hetao Irrigation Area of Inner Mongolia. The results showed that the effects of soil ameliorants and anti-alkali fertilizers were significantly better than the control treatment, anti-alkali fertilizers showed better in promoting the emergence and survival rates and the yield of oil flower, while soil ameliorants better in soil desalting and reducing soil alkalinity. Danlu bacterial fertilizer (T5) showed best for plant, and also more prominent for soil; while phosphogypsum (T1) best for soil, so they are recommended to be used for improvement of salinized soil.
