In order to study the effects of different fertilizer application rates on soil nutrients in Cele oasis,this study took Cele oasis in the southern margin of Tarim Basin as the research area under extreme arid environment,and three types of typical different fertility input of farmland at the edge of oasis. Three types of typical different fertility inputs of farmlands at the edge of oasis: high-input farmland,conventionally input farmland,and newly reclaimed farmland without fertilization were taken as the research samples. Another uncultivated sample plot was selected as a pair of conventional plots. From 2006 to 2018,the sampling time was from 2006 to 2010 and from 2017 to 2018,and the changes of 6 indicators such as soil organic matter content in four sample plots were analyzed. The results showed that: from 2006 to 2018,the organic matter content,total nitrogen content,alkalytic nitrogen content and available phosphorus content in the sample plots of high-input farmland in the study area were significantly higher than those of conventional input farmland,new reclaimed farmland without fertilization and unreclaimed pair farmland. The content of available potassium in uncultivated land was significantly higher than that in other three plots. By analyzing the average values of soil nutrients from 2006 to 2018,it was found that the soil nutrients in high-input farmland had a better improvement effect. The organic matter content,total nitrogen content,alkali-hydrolyzed nitrogen content and available phosphorus content increased by 204.22%,146.73%,46.45% and 633.75%,respectively,compared with those of uncultivated farmland. There were significant positive correlation between pH value and organic matter content(p<0.01),a significant or significant negative correlation between pH value and available potassium content,and a significant positive correlation between organic matter content and total nitrogen and available phosphorus content(p<0.01). This study can provide reference for rational fertilizer input and sustainable management of farmland during oasis reclamation.
