Evaluation of soil nutrient status of farmland in Bachu County,Xinjiang
摘要
Abstract
In order to comprehensively understand soil nutrients status in Bachu County,Xinjiang,1 500 soil samples were collect-ed from 10 townships in Bachu County in 2022,and the content of organic matter,total nitrogen,alkali-hydrolytic nitrogen,avail-able phosphorus,available potassium and pH in which were determined.The results showed that the contents of organic matter,to-tal nitrogen,alkali-hydrolytic nitrogen,available phosphorus,available potassium and pH value of farmland soil in Bachu County were 11.49 g/kg,0.71 g/kg,45.1 mg/kg,13.8 mg/kg,147.8 mg/kg and 8.02,respectively.According to the nutrient classification standards of the second national soil survey,the contents of organic matter,total nitrogen,alkali-hydrolyzed nitrogen,available phosphorus and available potassium were mainly in the fourth,fifth,fifth,fourth and third levels.The spatial distribution character-istic of soil organic matter content was higher in the southeast and west,and lower in the middle and north.The soil total nitrogen content showed a spatial distribution pattern of high in southwest and northeast,low in middle.The spatial distribution of soil alkali-hydrolyzed nitrogen exhibited a"flower pattern".The spatial distribution of soil available phosphorus content was spotty.The soil available potassium content showed a concentrated distribution feature,with relatively high levels in the Kashgar River basin and the central northern region of the Yarkand River.Compared with the soil samples from southern Xinjiang during the second soil sur-vey,the content of alkali-hydrolyzed nitrogen and available phosphorus increased significantly,while the content of available potas-sium decreased significantly.Based on the actual production in Bachu County,farmers should increase the application of organic fertilizer,control the application of nitrogen and phosphate fertilizer reasonably,and increase the application of potassium fertilizer during the production process.关键词
