中文摘要：
采用石膏、草炭、自制的盐碱改良剂、禾康土壤改良刹对吉林省西部盐碱旱作农田进行改良研究，分析了不同改良剂处理对玉米产量、植株特征及土壤理化性状的影响。结果表明，不同上壤改良剂处理，玉米产量增加，玉米株高、叶面积增加显著；土壤pH均比对照降低、土壤速效养分和有机质增加；土壤阳离子交换量增加，提高了土壤的保肥供肥能力。自制碱性农田土壤改良剂与草炭的改良效果较好，施入自制碱性农田土壤改良剂玉米产量比对照增加了，16．3％；施入草炭玉米产量比对照产量增加了8．2％。
英文摘要：
In this paper, gypsum, peat, self-made saline modifier, Hekang were used to improve saline-alkaline soil, combined with scientific cuhivation and management methods. Maize yield, soil physi-col and chemical properties were analyzed after treatment with different modifiers. The results showed that effects of soil modifier were obvious. Maize yield, plant height and leaf area were increased by application of soil modifiers. The soil pH decreased and soil available nutrients, organic matter and soil CEC were in-creased. The soil modifier improved the soil fertilizer capacity. The effects of self-made saline modifier and peat were better, maize yield was increased by 16.29% and 8.2%, respectively.
