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 ,对于宏观上指导农业施肥很有帮助
Through the statistical analysis of the present status of soil nutrients in three typical oasis farmlands in the southern margin of the Taklamakan Desert, the results show that there is a large degree of convergence and the difference between trace elements is greater. Fertilizers "is the macroscopic guideline of fertilizer application and fertilization in three counties. The spatial analysis of farmland soil nutrients between oases is very helpful for macro-guiding agricultural fertilization
