| 摘 要： | 研究了蔗园土壤养分的垂直分布特征。结果表明:(1)不管是在旱地蔗园还是在水田蔗园,0～30cm土层的有机质、水解氮、速效磷、速效钾等主要养分含量明显高于30～60cm的土层,但全氮、全磷、全钾在0～30cm土层与30～60cm土层之间没有明显的变化。(2)旱地蔗园的有效铁、有效锰和有效铜0～30cm土层比30～60cm土层高,有效锌含量在0～30cm的土层与30～60cm的土层之间变化不大。

| Abstract: | Vertical distribution of soil organic matter,pH and N,P,K nutrients was tested in soil from Changning county,Yunnan Province.The results showed that there were the same patterns in the dry and irrigation sugarcane fields.Soil available N,P,K and organic matter contents in 0-30 cm layer were significantly higher than that in 30-60cm soil layer.There were not notable differences for total N,P,K and pH between 0-30cmand 30-60cm layers.Available Fe,Mn and Cu in 0-30cm layer were significantly higher than that in 30-60cm in dry sugarcane crop fields.There was no difference for available Zn between 0-30cm and 30-60cm soil layers. |
