为了解酒泉市土壤养分状况。对酒泉市各县市的土样进行了养分测定。结果表明，酒泉市的农田土壤养分状况总体表现为有机质偏低，全氮和碱解氮中等偏低，速效磷和速效钾处于适宜和高水平。土壤pH总体为适宜和高水平。另外，各县(区、市)的土壤养分状况差异较大，均有一定比例的全氮、速效磷、速效钾等指标同时存在偏低或过高的现象。各县(区、市)应因地制宜，通过测土配方、合理施肥来提高土壤养分均衡供应能力，减少肥料施用量。

In order to understand the soil nutrient status in Jiuquan City， the soil sample from counties and cities in Jiuquan city was conducted to test the nutrient status. The results showed organic matter was low level， total nitrogen and alkali hydrolyzed nitrogen was medium to low； available phosphorus and available potassium was at suitable and high level； pH was general suitable and high. In addition， the soil nutrient status in different counties and cities was quite different， and there were certain proportion of soil， and the indicators of total nitrogen， available phosphorus and available potassium were lower or higher at the same time. It is suggested that in the future each county and city should adjust measures to local conditions， measure soil formula， and apply fertilizer reasonably， so as to improve the balanced supply capacity of soil nutrients and reduce the amount of fertilizer application.
