摘要
结合近两年对克拉玛依新垦荒地土壤理化性状的监测分析,对新垦荒地不同种植年限中的土壤盐分、养分、土壤pH值等变化进行了研究。研究结果显示:随着开垦年限的增加,土壤有机质、速效氮、速效磷、速效钾含量逐渐增加:土壤盐分随着种植年限的增加而逐渐减少;而土壤pH随着种植年限的增加缓慢降低。造成此种现象的原因可能与耕作方式和使用化肥有关。
By analyzing soil samples gathered from different new reclamed land which were reclaimed in different period, the soil physical and chemical properties were appraised. The study found that the content of soil organic matter, soil available nitrogen（N）, soil available phosphorus（P） and soil available potassium（K） of new newly reclaimed land were affected by Land used period. The content of soil organic matter, soil available nitrogen（N）, soil available phosphorus（P） and soil available potassium（K） was all enhanced with the increase of land planting period of new opened up badland; However content of soil total salt, pH value were decreased respectively with the increase of land planting period of new opened up badland. This results might be caused by the pattern of cultivating and the usage of fertilizer.
