中文摘要	对河西绿洲灌区土壤养分进行的研究表明,该区土壤偏碱性,有机质含量较低,碱解氮含量偏低,有效磷含量中等偏上,速效钾已表现出亏缺趋势;中量元素钙、镁含量均很高,有效硫含量处于较高水平;微量营养元素硼、铜、铁含量丰富,锰含量处于中等偏低水平,锌含量处于中等偏高水平.建议该区域应增施有机肥或秸秆还田,氮肥以追施为主,适当补充磷钾肥,土施或喷施一定量的微量元素锰和锌
英文摘要	The soil nutrient status of Hexi corridor oasis irrigation area was analyzed. The result showed that the soil of this area is alkalescence, the content of organic matter and alkali-hydrolysable nitrogen are low, while the content available phosphorus is in the upper medium level and available potassium has been shown deficit trends. The contents of secondary element-Ca and Mg are very high and the available sulfur is rich in the soil; the contents of micronutrient B, Cu and Fe are rich, but the content of Mn is in medium low level, and the content of Zn is in medium to higli level. The fertilization recommendations are adding organic fertilizer or straw-returning, mainly topdressing nitrogen fertilizer with supplementary P and K, soil application or spraying Mn and Zn
