Abstract:
Soil samples from 5 planting base in Lingwuchangzao demonstration garden in Ningxia were selected to determine the soil organic matter content,nitrogen,phosphorus and potassium contents,and the soil nutrient situation in Lingwuchangzao 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 phosphorus 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.
