摘要
在灵武长枣示范园区选择5个种植基地的土样进行土壤有机质、氮、磷、钾含量等的测定,分析宁夏灵武长枣示范园区土壤养分状况。结果表明:灵武长枣园区土壤有机质含量平均为14.13g/kg,全氮和碱解氮含量平均值分别为0.33g/kg和11.53mg/kg,全磷含量在0.19~2.06∥妇之间,速效磷含量为4.70-161.34mg/kg,速效钾含量平均值为319.9mg/kg;示范区土壤有机质含量差异较大,土壤中氮素严重缺乏,磷素含量较为适宜,但钾素充足;5个基地中红柳湾村和果园村的土壤肥力相对较高,银湖公司的土壤肥力较差。
Soil samples from 5 planting base in Lingwuchangzao demonstration garden in Ningxia were selected to deter- mine the soil organic matter content ,nitrogen, phosphorus and potassium contents,and the soil nutrient situation in Ling- wuchangzao demonstration garden in Ningxia. The results showed that the average value of soil organic matter content was 14. 13 g/kg,the total nitrogen and available nitrogen contents 0. 33 g/kg and 11.53 mg/kg respectively,total phos- phorus content 0. 19 ~ 2.06 g/kg, available phosphorus content 4. 70 ~ 161.34 mg/kg, available potassium content 319. 9 mg/kg in average;the soil organic matter content in demonstration garden had quite difference,with nitrogen lack, phosphorus appropriate, potassium adequate;the soil fertility in Hongliuwan and Guoyuan village were relative high, and in Yinhu company the soil fertility was poor.
