| 摘 要： | 采用玉米室内盆栽试验的方法,研究了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、有机肥、石膏、PAM等不同土壤改良剂对土壤结构的影响.研究结果表明,4类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,共同促进了当地盐碱土的改良;硫磺的最佳用量确定为在30.45 g/盆,并需要注意土壤通气性,防止发生反硫化作用,对玉米根系产生毒害;综合而言,PAM改良效果最佳.其次是石膏和S3处理.

| Abstract: | The effects of the application of different soil conditioners (sulfur,organic,gypsum,fertilizer,and PAM) on soil structure were studied by pot experiment with alkali-saline soil in Pingluo,Ningxia Hui Autonomous Region. All of the four soil conditioners reduced soil bulk density and increased soil total porosity. The improvement of soil physical structure,in combination with water use,promoted the improvement of local alkali soil. The best amount of sulfur was found to be 30.45 g/pot. Great attentions should be paid to soil aeration and prevention of the occurrence of anti-vulcanization. Among the four soil conditioners,PAM showed the best effect,followed by gypsum and S3 treatments. |
