对建水县肥料施用现状进行调查，并结合当地农业局提供的数据资料，分析该县主要农作物的农田施肥状况和养分结构。结果表明：建水县农田养分补充主要依赖化学肥料，有机肥施用量较少；化肥施用上存在重氮轻磷现象，氮、磷比例有所失衡，钾素、中微量元素养分供应不足。为提高肥料利用率，今后应增加有机肥施用量，控制化学氮肥用量，增施磷、钾肥，适当补施微肥。

Combining of data provided by the local agricultural bureau ,the fertilization status of main crops was analyzed in Jianshui County. The results showed that the complement of farmland nutrient in Jianshui County mainly relied on the supplement of chemical fertilizers, and the amount of organic fertilizer application was very small. There was a serious imbalanee in the ratio of nitrogen and phosphorus, and potassium and trace nutrients were in short supply. To improve the fertilizer utilization ratio,in the future,it should be emphasis on applieation of organie manure,control the amount of nitrogen fertilizer,increase the percentage of phosphorous and potassium fertilizers, and properly fill trace nutrient fertilizer.
