摘要
通过对塔克拉玛干沙漠南缘 3个典型绿洲农田土壤养分现状的统计分析得出 :大量元素的趋同性较大 ,微量元素的差别较大 ;“增氮、稳磷、补钾 ,有针对性的补施微肥”是 3县农业生产施肥的宏观指导方针 ;绿洲之间农田土壤养分空间差异分析研究 。
The statistics analysis of the farmland soil nutrients presen t situation between the three typical oases near the south Taklarmakan desert showed:The major nutrient elements comparatively trend similar and the mic ro-nutrient elements were comparatively different.Increasing nitrogenous fertil izer, stabilizing phosphate fertilizer, replenishing potash fertilizer and direc tly supplementing micronutrient elements fertilizer were three guide princip les of the agricultural production fertilization.The big scale space variation r esearch about the farmland soil nutrients was helpful to the centralize guidance for the agricultural fertilization.
