中文摘要	科尔沁沙地是我国东北部严重的荒漠化土地,也是京津风沙源地之一。为了探讨土壤改良剂组合(黏土、有机肥、腐植酸)对风沙土的改良效果,通过田间小区试验的方法,研究不同用量配比的有机改良材料对风沙土保水保肥性及玉米生长状况的影响。结果表明:土壤改良剂组合在施用黏土、有机肥、腐植酸分别为150 t·hm~(-2)、 30 t·hm~(-2)和3.75 t·hm~(-2)时,可以显著提高风沙土的持水性、保肥性,促进玉米植株生长,提高产量,其增加幅度分别为: 46.61%、197.59%、36.67%和70.08%。与对照相比,施用土壤改良剂可以显著提高玉米拔节期叶片SPAD值(叶绿素的相对含量), 其增幅达69.32% ~ 91.63%。因此,认为黏土、有机肥与腐植酸复合改良剂,有利于维持较高的土壤生产力,同时,对该地区沙土培肥具有重要作用。
英文摘要	Land desertification is serious in the Horqin Sandy Land in northeast China,and the sandy land is also one of the Beijing-Tianjin sandstorm sources. In order to investigate the effects of applying soil organic materials(clay,organic fertilizer and humic acid) on the Aeolian sandy soil improvement,the effects of soil organic improvement measures on fertility of Aeolian sandy soil and maize growth were studied through field plot experiment. The results showed that the capacities of water retention and nutrient retention of Aeolian sandy soil as well as the maize growth could be significantly improved by applying clay,organic fertilizer and humic acid for 150 t·hm~(-2), 30 t·hm~(-2) and 3.75 t·hm~(-2),and the maize yield could be increased by 46.61%,197.59%,36.67% and 70.08%,respectively. Compared with the contrast,the maize leaf SPAD value could be significantly increased by 69.32% - 91.63% by applying soil conditioner. Therefore,it was considered that it was advantageous for maintaining a high soil fertility and of important significance for fertilizing Aeolian sandy soil to apply the soil conditioner composed of clay,organic fertilizer and humic acid in the study area.
