摘要: 对内蒙古自治区赤峰市农牧交错区撂荒地和玉米(Zea mays L.)种植年限为1、5、10、50年的土壤氮磷养分进行分析和比较,旨在探明玉米种植年限对土壤氮磷养分的影响。结果表明,土壤氮磷养分随玉米种植年限的延长表现出明显的增加趋势;土壤有机质以及氮磷养分与种植年限之间均呈显著或极显著正相关关系。玉米种植年限达50年的土壤中氮磷养分含量达到了最高值。因此,在该区玉米种植管理过程中,要结合各养分因子随年限的变化规律以及不同养分因子间的相关性,因土施肥、合理培肥,达到玉米增产以及环境保护的目的。

Abstract: The soil nitrogen and phosphorus nutrients were analyzed and compared in abandoned land and maize soil planted for 1, 5, 10 and 50 years in agro-pastoral ecotone in Chifeng City, Inner Mongolia Autonomous Region, in order to investigate the effects of maize planting years on soil nitrogen and phosphorus. The results showed that the soil nitrogen and phosphorus nutrients increased obviously with the increase of maize planting years. Soil organic matter and nitrogen and phosphorus nutrients showed a significant or extremely significant positive correlation correlated with planting years. Soil nitrogen and phosphorus contents reached the highest level under 50 planting years. Therefore, in the process of maize planting management in this area, it was necessary to combine the change rule of each nutrient factor with years and the correlation among different nutrient factors, so as to achieve the purpose of increasing maize yield and environmental protection through soil fertilization and rational fertilizer cultivation.

Key words: planting years, maize(Zea mays L.), soil nitrogen, soil phosphorus, agro-pastoral ecotone
