| 摘 要： | 以长期定位试验点新疆伊犁河谷新垦绿洲灰钙土为研究对象,选择不同土地利用类型,采集上层(0～20 cm)、中层(20～40 cm)和下层土壤(40～60 cm)样品,分析土地利用类型对灰钙土土壤有机质、全氮和全磷的影响.研究结果表明:土壤有机质和全量氮磷含量表聚性特征明显;垂直分布总体变化趋势均为由上到下依次减少,且都以40 cm处为其变化转折点;从土壤有机质含量来看,以天然荒地最高,树上干杏林地和杨树林地次之,撂荒地和小麦-油葵轮作地较低;从土壤全氮含量来看,以天然荒地最高,树上干杏林地和撂荒地次之,杨树林地和小麦-油葵轮作地较低;从土壤全磷含量来看,树上干杏林地最高,天然荒地、撂荒地和杨树林地次之,小麦-油葵轮作地最低.植被类型对土壤质量影响显著,在今后的土地资源利用过程中,在施用无机化肥的同时也要注意推广秸秆还田,增加施用有机肥,做好土壤的培肥工作.

| Abstract: | Organic matter,total nitrogen and phosphorus of oasis sierozem in the Yili valley of Xinjiang are investigated in terms of soil features and spatial distributions.The results show that,concentrations of soil organic matter,total nitrogen and phosphorus in surface study soil are significantly higher than respective values of subsoil.The concentrations all gradually decreases with soil depths,with a turning point 40 cm under soil surface.The soil of natural wastelands has the highest amount of soil organic ma... |
