摘要
大田试验结合玉米室内模拟盆栽,研究宁夏回族自治区石嘴山市平罗县姚伏镇大兴墩村的盐碱土在施用硫磺、石膏、有机肥、PAM等不同改良剂后,土壤水分及相关性质的变化。结果表明：（1）4种改良剂均有效降低了土壤容重,土壤空隙度随之增加,土壤物理结构的改善与水分利用相互配合,共同促进了盐碱土的改良;（2）硫磺的最佳用量在675-900 kg/hm2之间;（3）就4种改良剂综合而言,PAM表现出最佳效果。
With field and pot experiments,a research was carried out on the effect of different soil conditioners（sulfur,PAM,organic fertilizer） on water and other characteristics of alkali-saline soil in Niaxia.The results were shown as the followings：（1） All of four soil conditioners decreased soil bulk density efficiency,and the improvement of soil physical structure in combination with water use promoted alkali soil commonly;（2） The best amount of sulfur was between 675～900 kg/hm2;（3） Among four soil conditioners,PAM showed the best effect.
