开展对塔河铁矿废弃地土壤速效养分含量的测定以及对比分析,通过对实验结果的科学分析,对该地区的植被恢复提供科学指导。实验结果表明,该地区土壤中速效N、P、K含量与对照地均显著不同,速效N含量明显降低,速效P和速效K含量明显增加。速效N与速效P含量的异质性非常明显,而速效K含量则仍具有一定的均一性。
Carrying out the determination and comparative analysis of available soil nutrient content in the wasteland of Tahe Iron Mine, and providing scientific guidance for the vegetation restoration in the area through scientific analysis of the experimental results. The experimental results showed that available N, P and K contents in soils were significantly different from those in the control land, the content of available N was obviously decreased, and the contents of available P and available K were significantly increased. The heterogeneity of available N and available P content is very obvious, while the available K content still has a certain degree of homogeneity.
