摘要: 以大兴安岭南麓阿荣旗农田土壤为研究对象,探索阿荣旗农田土壤养分空间异质性。结果表明,阿荣旗农田土壤有机质、全钾、全磷、全氮含量分别为47.48、29.31、1.57、2.27 g/kg,土壤养分总体含量丰富,适宜作物生长,土壤各养分变异度均在10%~100%,为中等变异程度且各样点单因素显著,各样点存在显著的空间异质性。为合理优化施肥方案,改善耕作方式,实现阿荣旗农田各样点土壤养分平衡、地力提升提供科学依据,为构建大兴安岭南麓耕地地力评价体系提供理论支撑。

Abstract: This study took the farmland soil of Arong Banner at the South foot of Daxinganling as the research object,to explore the spatial heterogeneity of the farmland soil nutrients in Arong Banner. The results showed that the contents of organic matter, total potassium, total phosphorus and total nitrogen in the farmland soil of Arong Banner were 47.48, 29.31,1.57, 2.27 g/kg, respectively. The nutrient content of the soil was rich and suitable for crop growth. The variability of the nutrients in the soil was between 10% and 100%, which was a moderate degree of variability, and the single factor at each point was significant, and there was significant spatial heterogeneity at each point. It provided a scientific basis for reasonably optimizing fertilization schemes, improving farming methods, realizing soil nutrient balance and improving soil fertility at various points of Arong Banner farmland, and provided theoretical support for constructing a farmland fertility evaluation system at the Southern foot of Daxinganling.

Key words: soil nutrients, spatial heterogeneity, variability, relevance, south foot of Daxinganling, Arong Banner
