| 摘 要： | 通过连续四年在内蒙古河套灌区低产盐碱地定点、定位试验与定时测土分析，明确了土壤耕层增施有机物料建立有机质富积层，能够改善土壤理化性状，尤其是能降低土壤表层含盐量，提高作物保苗率和显著增加作物产出量。

| Abstract: | The paper concludes and analyzes the 4-year experiments on saline farmland in Hetao plain of Inner Mongolia.The results show that organic matter accumulated in cultivated horizon can improve soil properties,the salt content in surface stratum obviously decreases.Thus,the seedlings grow well and the grain output remarkedly increases. \ \ |
