【目的】分析昌吉市阿什里乡牧民定居区耕地的土壤养分情况,为其合理施肥和土壤改良提供科学依据。【方法】采用野外常规取样和实验室分析结合的方法,测定土壤有机质、碱解氮、速效磷、速效钾、pH值等指标。【结果】研究区域土壤养分中有机质的含量在9.82~15.96g/kg,平均为14.24 g/kg;碱解氮含量在20.67~82.70 mg/kg,平均为39.05 mg/kg;速效磷含量在0.54~7.63 mg/kg,平均为3.12 mg/kg;速效钾含量在19.30~34.47 mg/kg,平均为25.80mg/kg;pH值在6.9~8.6,平均为7.9。【结论】该牧民定居点的耕地土壤养分水平较低,耕地质量以四至六级耕地为主,耕地质量较差。
【Objective】 The objective of this study was to analyze the soil nutrient status of cultivated land in herdsman settlements in Ashiri Township, Changji City, providing a scientific basis for its rational fertilization and soil improvement. 【Method】 The indexes of soil organic matter, available nitrogen, available phosphorus, available potassium, pH value and so on were determined by routine combination of field sampling and laboratory analysis. 【Result】 The results showed that the contents of organic matter in the soil nutrients ranged from 9.82 to 15.96 g / kg with an average of 14.24 g / kg and the alkali-hydrolyzable nitrogen contents ranged from 20.67 to 82.70 mg / kg with an average of 39.05 mg / kg and available phosphorus at 0.54 ~ 7.63 mg / kg, with an average of 3.12 mg / kg; available potassium content was 19.30 ~ 34.47 mg / kg with an average of 25.80 mg / kg; pH ranged from 6.9 to 8.6 with an average of 7.9. 【Conclusion】 The soil nutrient level of cultivated land in settlements of herdsmen is relatively low. The cultivated land quality is dominated by four to six cultivated lands, and the cultivated land is of poor quality.
