宣城市岗坡地土壤养分特征及其与颗粒组成关系
|
摘要
对宣城市岗坡地土壤养分特征及其与颗粒组成关系进行了分析,结果表明:⑴不同土地利用类型中,林地土壤有机质和全氮含量显著高于其它3种土地利用类型;耕地和新耕地土壤全磷、速效养分含量都高于林地和灌丛;土壤有机质、速效氮和速效磷含量与土地利用类型有显著的相关性。⑵土壤有机质、全氮含量中、上坡位都显著高于下坡位,全磷和速效养分的含量随坡位下降呈显著增加趋势;有机质、全磷和速效磷与坡位有显著的相关性。⑶土壤有机质与粘粒(<0.002 mm)和粉粒(0.002~0.02 mm)的含量均呈显著的正相关,与砂粒(0.02~2 mm)含量呈显著负相关,全氮与粉粒含量呈现显著正相关,全磷与粉粒、砂粒含量显著正相关。
The characteristics of soil nutrients and the relationship between soil nutrients and particles in hills of Xuancheng were analyzed.The results showed that:(1) In different land use types,the content of soil organic matter and total nitrogen in woodland were significantly higher than that of the other three land use types.The contents of total phosphorus and available nutrient in arable land and new arable land were higher than that in woodland and scrub.The correlation between organic matter,available nitrogen and available phosphorus and land use types was significant.(2) The contents of organic matter and total nitrogen in middle slope and up slope were significantly higher than that in downhill slope,and the total phosphorus and available nutrient showed a significant upward trend as the slope position decreased.There were obvious correlations between organic matter,total phosphorus and available phosphorus and the slope position.(3) There was an obviously positive correlation between organic matter and clay(<0.002 mm) and powder(0.002~0.02 mm),and an significantly negative correlation between organic matter and sand(0.02~2 mm).Meanwhile,the correlation between total nitrogen and silt were significantly positive,the same to the correlation between total phosphorus and the contents of silt and clay.
