荒漠绿洲区不同土地利用方式下土壤养分差异分析
Analysis on soil nutrients difference under different land use patterns in desert oasis region
摘要
Abstract
In northern tarim basin desert oasis region (Weigan-kuqa river delta oasis)as the research object, through the field sample collection and indoor analysis,soil nutrient elements of different land use patterns(organic mat-ter,total nitrogen,alkali solution nitrogen,available phosphorus and available potassium)were analyzed,the results show that:(1)the spatial variation of the soil nutrient elements from strong to weak order of sequence is available phos-phorus>alkali solution nitrogen>available potassium>total nitrogen>organic matter.(2)under the different soil depth,the contents of soil organic matter,total nitrogen,available phosphorus and available potassium showed more sig-nificant difference between the different land use patterns(P<0 .05),while soil alkali solution nitrogen was no signifi-cant difference between the different land use patterns(P>0 .05).(3)Under the different patterns of land use,the re-lationships of correlation were strong between the soil nutrient index of organic matter,total nitrogen and alkali solution nitrogen .The relationship of correlation between the available phosphorus and available potassium was relatively weak .关键词
