| 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。

| Abstract: | 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... |
