| 摘 要： | 本文系统研究了神东矿区马家塔露天采坑复垦区土壤养分状况,结果显示:复垦区土壤基本上为原始回填土,剖面层次不发育,成土程度很低;土壤机械组成以砾石、粗沙为主,含量高达90%。有机质、含碱解氮含量略高于未受扰动的原状土壤,但速磷、速钾含量均低于原状土壤,总体评价土壤属于养分贫乏型;成土程度低、养分含量少是农林业生产水平不高的主要原因。研究表明通过改良复垦工艺以及提高复垦区生产管理水平是提高土地生产力的主要措施。

| Abstract: | The condition of nutrients in soil reclamed around Majiata reclaimed regions was studied.The results showed that organic matter,the amount of N were slightly high in original shape soil,however,the amount of P,K was slightly low in original shape soil.Thegravel,thick sand content is high,the quality is thicker,the section structure is obscure,coming short of the agriculture and forestry industry to produce still need familiar to turn the degree,the study also showed that it play a important role to improve soil nutrient by improve reclamation technics and improve reclamation manage level. |
