| 摘 要： | 为了了解野生樱桃李(Prunus divaricata)下土壤养分状况,为野果林资源的合理利用与保护提供有价值的参考,对新疆伊犁霍城县大、小西沟野生樱桃李林下土壤发育有机质与速效养分含量进行了分析。结果表明,野生樱桃李林下的土壤有机质属于中等变异;有机质含量与速效氮、速效磷、速效钾含量呈极显著正相关;速效氮、速效磷、速效钾的含量随着土层深度的增加而减少,p H随着土层深度的增加而增大;土壤速效氮、速效磷、速效钾的均值分别为295.71、39.75、391.05μg/g,有机质含量均值为0.31%。

Correlation Analysis and Nutrient Characteristics of Soil under Prunus divaricata in Daxigou and Xiaoxigou Valley,Yili, Xinjiang |

| Abstract: | In order to understand the nutrient status of the soil under Prunus divaricata, and provide valuable reference for the rational utilization and protection of wild fruit forest resources, organic matter and avaiable nutrients of soil under P. divaricata in Daxigou and Xiaoxigou valley, Huocheng country, Yili, Xinjiang, was analyzed. The results showed that, the variance coefficient of organic matter of soil under P. divaricata was moderate. The soil organic was significantly positively correlated with available nitrogen, available phosphorus and available potassium. The content of available nitrogen, available phosphorus and available potassium was decreased with the increase of soil depth, but the pH value was increased. The average value of soil available nitrogen, available phosphorus, available potassium and organic matter was 295.71,39.75,391.05μg/g and 0.31%, respectively. |
